COVID-19 and Building Ventilation

Posted on by melinkadmin

Keeping your HVAC breathing through the Covid-19 pandemic.

The United States continues the fight against COVID-19, many reopened businesses are concerned about indoor air quality. As a result, new requirements are being implemented for the public’s safety.

Recently, New York allowed for the reopening of shopping malls but with a mandate from Gov. Andrew Cuomo: Update HVAC filters with at least a MERV-11 rating to capture the potentially airborne coronavirus particles. Likewise, Colorado’s Denver Public Schools unanimously approved Denver schools to get ventilation upgrades to help stem the spread of coronavirus. So what do these guidelines mean, and could other states follow these policies?

HVAC Filters

Minimum Efficiency Reporting Value (MERV) is used to measure the effectiveness of air filters on a scale of 1 to 16. The higher the MERV rating, the greater the filtration, i.e. the smaller the particles it can catch. The Centers for Disease Control and Prevention (CDC) recommends to improve central air filtration to the MERV-13 level (or the highest compatible with the filter rack) and to seal edges of the filter to limit bypass.

However, updating an HVAC system’s air filters may not be as simple as it sounds. For instance, a common factor that will get overlooked is that most HVAC systems that were designed for lower MERV filters (likely most of them) will need to be rebalanced for the new filters. The higher the MERV rating, the better the filtration but also the higher the static pressure (or resistance) that the fan must work against, resulting in a drop in airflow. The reduced airflow could cause comfort problems and even frozen coils. To prevent these issues, the airflow will need to be measured with the new filters installed, and then the fan speed will need to be increased to achieve the designed airflow.

Yet this is still not a “one size fits all” solution for all. Many HVAC units cannot handle the higher-rated filters. Using a filter with a higher MERV rating may cause the motor to burn out. This is why it is important you have a trained technician review your unit before making any changes.

Other Building Ventilation Recommendations

In addition to replacing filters, ASHRAE recommends the following actions, with the ultimate goal being consistent and frequent air changes:

  • Increase outdoor air ventilation (use caution in highly polluted areas); with a lower population in the building, this increases the effective ventilation per person.
  • Open minimum outdoor air dampers, as high as 100%, thus eliminating recirculation. (During mild weather, thermal comfort or humidity within a facility normally wouldn’t be affected. During extreme weather, this clearly becomes more difficult to control.)
  • Consider portable room air cleaners with HEPA filters.
  • Consider Ultraviolet Germicidal Irradiation (UVGI), protecting occupants from radiation, which is particularly in high-risk spaces such as waiting rooms, prisons and shelters.

Developing Solutions

While the experts are recommending the above items, they are not mandatory across the country. States’ policies vary. Not to mention that COVID-19 research is still developing.

COVID-19 changing building ventilation

The result, in the near term, is likely to be a patchwork — some commercial buildings, schools, colleges, and other facilities will make investments, while others will not. One example of an organization making the investment to fight COVID-19 is KIPP DC, a publicly funded and privately operated network of seven school campuses with 1,200 employees and 7,000 students. KIPP DC has taken huge measures, working to find the ideal system optimized to filter the coronavirus.

Creative Financing Pays for Itself with Intelli-Hood

Posted on by melinkadmin

Drastic Turn

2020 has been the most unique year to date, especially when it comes to the economy. Coming off 2019, the economy was strong, companies were reinvesting and spending money. The economy looked like 2020 would be another great year — until March. Enter COVID-19; companies that could endure the pandemic had to pivot fast. Predictions for a record year were gone in a moment. For months, businesses across the country shut down.

Like other businesses, Melink tried to come out the other side of COVID-19. Many felt more timid than ever about spending cash, and understandably so. Numerous projects put on hold as capital expenditure budgets froze for 2020, 2021, and even 2022 in some cases. 

Melink’s company mission is to change the world one building at a time. We achieve this by implementing energy efficiency and renewable energy solutions into commercial facilities for decision makers. Intelli-Hood is a Demand Control Kitchen Ventilation (DCKV) system that saves money by reducing monthly operating expenses in commercial kitchen facilities. Often, Intelli-Hood pays for itself in one to three years, making it an attractive energy conservation application.

Intelli-Hood Controls

The question arises: How do we change the world one building at a time with spending on an indefinite pause? 

Creative Financing Solution

I worked with a university that wanted to implement Intelli-Hood in a kitchen. Without any utility rebates taken into consideration, the $62,000 project would pay for itself in less than three years. Everything was moving smoothly until COVID-19 put everything on pause. But Melink’s committed to working with customers and customizing energy solutions. As a result, discussions were continued with the university. We were able to come up with a creative financing solution that’s win/win for all parties: an Equipment Loan Program. Thus, the customer paid nothing out of pocket, while simultaneously being cashflow-positive the second we walk off the job site. Working with a lender, we got the $62,000 financed for the university over five full years at monthly installments of $1,287. This was a total investment of $77,220.

The Savings Stack Up

At Melink, our proposals come turnkey, along with a custom Energy Savings Report. The reports give an idea of how much money you will save with Intelli-Hood. In this instance, the customer was going to save more than $18,000 in energy savings the first year alone, resulting in a positive cashflow of almost $3,000. On average, utility rates go up 3% every year, meaning that with the customer locked into an installment payment of $1,287 for 60 months, the positive cashflow will continue to increase year over year. After five years, the loan will be paid off in full and the benefits really kick in, saving more than $20,000 per year. Thus, creative financing creates more opportunities for customers to save on energy costs.

Looking at a 10-year period, the customer is going to save more than $130,000 without having to pay anything upfront. While a traditional purchase would save more money ($148,000) over the same 10-year period, it would require the full upfront cost paid in full.

So, if your business is in a similar position where your budget is paused but you are still interested in saving energy, reducing greenhouse gasses, and cutting operating costs – maybe this creative financing can work for you, too. We can continue to work together to change the world one building at a time, all while exploring realistic options in the current economic climate. 

‘Hire a Veteran Day’ is Every Day at Melink

Posted on by melinkadmin

July 25 is National Hire a Veteran Day. At Melink Corporation, we have veterans at nearly every level of our business, and we make hiring veterans a priority year-round.

Currently, there are 12 military veterans in the Melink family. Four are in leadership roles and eight serve in roles ranging from sales to field service, via Melink’s national network of technicians. In total, veterans comprise approximately 12% of Melink Employee-Owners.

National Hire a Veteran Day - Statistics for Melink's military veteran employees

We have found that our military veterans are loyal, hardworking, and have a strong sense of integrity. They bring a different perspective on life, leadership, and hard work. Hiring and employing veterans offers Melink a chance to support those that have given so much for our country. It is a mutually beneficial relationship, and our veterans’ military values easily translate to Melink’s core values.

How We Hire Veterans

To help us get matched with veterans, we work with a couple recruiting firms. Originally, we started working with the firms to find the right type of candidate to fill the challenging role of a Melink Field Service Technician.

For this role, veterans seem to be a natural fit and are drawn to the position. The role requires travel, a self-reliant work ethic, and adherence to a specific code of conduct. Plus, a technician is often away from his or her family for an extended amount of time.

For me, hiring veterans is rewarding on several different levels. I feel that we understand the capabilities of these individuals and that we can translate their military experience into the civilian job market.

Due to several of us in the leadership team are veterans ourselves, we have a unique advantage when hiring veteran talent. We truly enjoy the chance to provide opportunities to those who have also sacrificed and taken up the call to serve our nation.

Meet Our Veterans

We are proud of our veterans and stand by them:

Q&A: What Is Net Metering?

Posted on by melinkadmin

If you are considering solar for your commercial building, an important concept to understand is net metering, whether it applies in your state, and how it works with your utility company.

What is Net Metering?

Net metering is a billing incentive that offers credits to the owner when a solar PV system produces more electricity than consumed. Any excess power generated through solar feeds back into the utility grid, thus qualifying the owner for a “credit” on his or her electric bill. Think of “debits” as energy used from the grid, or any electricity that solar power cannot cover during a given period.

What is net metering? Day to night graphic of energy flow from solar panel to grid
This animation illustrates the flow of energy production when electricity is used over the day and night. During the day, the owner generates credits when the building’s solar panels produce more power than needed (net metering). The meter spins backwards, and excess electricity gets sent to the grid. At night, the building’s electricity needs aren’t fulfilled by solar due to lack of sunlight. Its power is therefore sourced, or debited, from the grid.

How Does Net Metering Work?

  • Credits = Power produced by solar
  • Debits = Electricity consumed from the grid

The net of these two is how net metering functions, factoring in whether the owner is charged for grid usage, or owed credits for solar production.

Think of the daily variations of energy usage in the typical home. Assume that residents typically consume most of their electricity in the mornings and evenings, before and after work. If there is little or no solar production during the time when electricity is needed, energy will come from the grid. Hence, debits — or the costs one would otherwise see on the utility bill.

Solar energy systems usually hit peak production in the afternoon when sun exposure is maximized. So, what happens to all the solar generation during the day if the power is not used or needed? The excess solar power spins the meter backwards and sends energy to the grid. Hence, these credits serve to help offset your electricity bill.

Why is Net Metering Important?

Net metering ensures the owner is credited for those natural swings in daily production. Depending on your building’s energy usage and time of peak demand, net metering can help maximize the owner’s savings from solar power. Understanding net metering laws can help determine the ideal size of the PV system, after factoring in daily, weekly, monthly, or annual estimated energy usage.

If you are considering switching to solar, these net metering regulations should guide the solar company to design your system in the most cost-effective way. After evaluating your electricity usage, the solar provider should factor in net metering compensation to get the best return on your investment, depending on how much PV generation you prefer.

How Does Net Metering Compensation Work?

Forms of compensation will vary by state and utility company. Generally, the owner should be charged only for the net electricity used by the end of the month. In some instances, if more power is generated by solar than consumed over a month or year, the utility will roll over those credits to the next period. In other scenarios, the consumer will be compensated at the retail or wholesale rate at the end of a given cycle.

Consumers must elect to receive credits in a contract with their utility provider. Tariff sheets, or compensation rates, are provided by the utility and explain whether solar overproduction results in the following:

  • Monetary bill credits
  • Check payments
  • kWh credits to offset future consumption from the grid

It is important to fully understand your state’s policies regarding net metering compensation. EnergySage explains how net metering rules can vary: “If you do generate more electricity than you use in a year, utilities in some states will let you carry credits over into future years, while others will reduce your credits.”

Do not let credits confuse you for cash payments, unless you live in a state that allows for that type of compensation. While you can stock up on credits to cover power you may need from the grid throughout the month or year, do not assume the utility companies will be sending a check covering the full retail rate.

Does Every State Have Net Metering?

While net metering is authorized in most states, there are different approaches to how they distribute credits, assign eligible technology, and handle capacity limits. The National Conference of State Legislatures expands on state-specific laws and advises one cannot make assumptions about compensation without digging into state rules. For example, “California credits excess generation to a customer’s next bill at retail rate. After a 12-month period, customers can choose whether to roll credits over indefinitely or receive a payment for credits at the wholesale rate. If no option is selected, credits are granted to the utility with no customer compensation.” In this case, the owner can opt in for credits at the end of the year, but it will be at the wholesale rate. Month to month, however, they receive credits at the retail rate.

Net metering policies were originally intended for areas with lower solar adoption. As more and more states become reliant on clean energy, we can expect some changes to occur. Regardless of your state or utility’s current policy, it’s important to understand how different factors can affect your long-term savings when installing solar panel systems.

Does Net Metering Eliminate Utility Bills?

A common misconception is that if you can attain Net Zero Energy for your building, you will not receive a utility bill. This is false, as the owner is still tied to the utility company in some capacity. If you are producing a lot of solar power, the building consumes the amount of electricity needed, and the remaining power shoots back onto the grid. Credits are accumulated through net metering and impact whether your utility bill is $0, or a lesser amount than in the past.

Sure, you may owe less to the utility, and the bill may look different depending on how much energy solar can offset. However, in most cases, solar will supply as much electricity as possible, and the remaining power is met by the grid.

How Does Net Demand Work?

The following chart shows a live example of how net metering works when savings occur with solar PV generation. These daily variations in current demand (debits), layered against solar PV power (credits), result in the building’s net demand. 

The solar energy system at this site overproduces during the first two days since there is ample sunlight and little demand. The utility is crediting the owner’s account for that overproduction, which is then used to offset the bill when the system is under-producing.

Net metering occurs in the areas that display overproduction from solar. Excess electricity causes the meter to spin backwards. In these cases, solar generates more power than the actual usage. That excess power is sent back to the grid, while “credits” accumulate on the account.

Savings occur in every green area where solar produces power. For example, although the system is not overproducing during the last day, solar is still helping to offset part of the demand costs, or “debits.”

Net Metering in Office Building

WEEKEND: On Saturday and Sunday, the building load is very low. Solar power is generated throughout the day with plenty of sun, which causes a lot of energy to be exported to the grid (accumulating credits). Credits are being used up at night while there is still some electricity load.
MONDAY: The building energy load spikes, causing debits on the account. Solar generation doesn’t show a consistent curve since it’s cloudy outside. For the most part, the building is pulling power from the grid (at a reduced rate), and energy is exported for a small amount of time in the middle of the day.
TUESDAY: A nice, sunny day. In the morning, the building starts pulling power from the grid as the energy load shoots up when workers arrive. Then, the load from the grid starts to slowly reduce as some of the electricity is produced by the solar array. Then, eventually, the building exports power back to the grid (accumulating credits), before the cycle reverses again.
WEDNESDAY: No net-metering occurs because of the lack of sun. However, the load from the grid is reduced and savings still occur. The net of the debits and credits appears in the middle.

Indoor Dew Point: Maintaining Thermal Comfort, Avoiding Building Damage

Posted on by melinkadmin

Condensation, moisture absorption and, subsequently, mold or organic growth are often a result of high indoor dew point combined with cool surface temperatures. For example, if a facility’s indoor dew point is above 60oF, it is possible that moisture will begin to condense on cool surfaces like ductwork, chilled water supply lines, windows, or refrigeration systems. This collection of moisture can cause damage to the building, as well as to merchandise. It can even promote organic growth over time.

In addition to the risk of moisture accumulation, ASHRAE recommends maintaining a dew point below 62 oF to meet thermal comfort for approximately 80% of occupants; a dew point of 45 oF is recommended to maintain summertime humidity comfort levels.

Monitoring Dew Point

Consider this: You are a kid in a candy store with a plethora of delicious options in front of you. You sort through the store and boil your decision down to two candy bars.

Option A: The tried and true milk chocolate bar. Nothing fancy but classically delicious.

Option B: Fluffy nougat topped with caramel and peanuts, coated in milk chocolate. An exciting snack bursting with flavor.

Did you choose Option A or Option B?

If I had to guess, you chose Option B as it gives you more variety with your purchase! Now, what if I told you that the decision you just made also can apply to thermal HVAC design and dew point monitoring principals?

Option A: A design principal of maintaining 60% relative humidity (RH).

Option B: A design principal of maintaining a 60oF dew point.

Both are similar and help maintain a healthy building, but maintaining a 60oF dew point (Option B) is inherently better and offers a more reliable risk indicator. Using 60% RH as an indicator (Option A) is unreliable as it creates needless concern when air temperature is cool. In the example below, you can see that the amount of water vapor in the air remains the same while relative humidity concentration varies depending on the temperature of the air.

Image Source

Conversely, a facility manager or building owner may have a false sense of security when indoor air temperature is above normal levels because relative humidity will decrease as air temperature rises. These reasons are why dew point should be used as a threshold of concern. Dew point will not only factor in moisture content and temperature of the air but also provides a risk indicator for condensation and moisture absorption, which should be a facility manager’s primary concern.

Using Indoor Dew Point as a Risk Indicator

If you are already using indoor dew point as a risk indicator for indoor moisture activity, then continue to do so! Specifically, look to ensure that indoor dew point remains below 60 oF during cooling operations to reduce the risk of moisture absorption, condensation, and organic growth.

If you are not using indoor dew point as your risk indicator, now is the time to do so! You could be surprised to learn that measuring relative humidity alone may not be keeping your facility safe.

If you are already noticing signs of moisture accumulation, mold or organic growth, then ASHRAE recommends implementing the following HVAC factors to reduce your risk:

  • Ensure that ventilated air is dehumidified to a dew point below the indoor dew point when the building is in cooling mode.
  • Ensure that all condensation inside HVAC components is being properly drained.
  • Ensure that indoor surfaces are not cooled to temperatures below indoor dew point during occupied and unoccupied modes.
  • Keep indoor dew point low enough to ensure that condensation does not occur on cool surfaces of HVAC components, building materials, or building furnishings.
  • Ensure that humidifiers are sized, installed, and controlled properly to avoid the risk of overloading indoor air with humidity.
  • Ensure that cool HVAC and plumbing components are properly insulated to keep their surfaces about 10 oF above indoor dew point.

These simple steps — in addition to proper HVAC ventilation, indoor air monitoring, indoor air verification, and keeping an eye on seasonal changes — can help ensure that your facility is operating in a safe manner while reducing risk of mechanical damage, moisture accumulation, or organic growth.

Professional Development: ASHRAE & Melink

Posted on by melinkadmin

Melink Corporation is passionate about supporting the HVAC industry through its clean energy solutions. To share our field knowledge in commercial kitchen ventilation, as well as test and balance, several employees serve on professional boards like the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE).

ASHRAE logo

What is ASHRAE?

ASHRAE is a professional association to advance the design and construction of heating, ventilation, air conditioning, and refrigeration systems. The international group has more than 50,000 members in more than 130 countries. Most members are building service engineers, architects, mechanical contractors, building owners, and equipment manufacturers. ASHRAE is known for supporting research projects, offering education programs, and publishing technical standards.

Overall, ASHRAE’s technical standards support safety, occupant health, and energy efficiency. These standards establish consensus for testing methods for use in commerce, as well as the performance criteria to guide the industry. ASHRAE publishes the following three types of voluntary consensus standards:

  • Method of Measurement or Test (MOT)
  • Standard Design
  • and Standard Practice.

ASHRAE does not write rating standards unless a suitable rating standard will not otherwise be available. ASHRAE is accredited by the American National Standards Institute (ANSI) and follows ANSI’s requirements for due process and standards development.

For many years, Melink Corporation has supported ASHRAE. Employee-owners, including CEO Steve Melink, have written journal articles, technical standards, and presented at conferences. Most recently, Jason Brown (Senior Sales & Applications Engineer) and Bryan Miller (Vice President of Technology) have volunteered their time and expertise.

Here’s a closer look at Melink’s support of ASHRAE:

 
Bryan Miller

  • ASHRAE operates through committees. Through the committee structure, members decide policy, develop procedures, and direct the organization’s activities. Brown and Miller have been active for several years on two ASHRAE committees. Brown is a voting member of the following committees, meaning he has influence on what does and doesn’t pass in the committee proceedings:

    Technical Committee on Commercial Kitchen Ventilation (TC 5.10) Technical Committees (TC) are responsible for identifying research topics, proposing research projects, selecting bidders, and monitoring research projects funded by ASHRAE. Information about research programs is discussed at each TC meeting and at the TC’s Research Subcommittee meeting. For instance, the TC 5.10 Committee, in which Brown serves, is concerned with the design, construction installation, commissioning, and sustainable operation of code-compliant commercial kitchens. The committee is also involved with revisions/updates to model codes such as the International Mechanical Code (IMC) and writing/revising ASHRAE Standards. Additionally, the TC develops sessions for ASHRAE’s winter and annual conferences.

    Standards Committee for Commercial Kitchen Ventilation (SSPC 154) This Standards Committee provides design criteria for the performance of commercial cooking ventilation systems in regard to kitchen hoods, exhaust systems, and replacement air systems. Serving on this committee primarily has entailed attending and participating in meetings that occur twice per year.
  • Brown and Miller have assisted with updating sections of the ASHRAE Handbook. The ASHRAE Handbook is a series of four volumes covering HVAC Applications, Refrigeration, Fundamentals, and HVAC Systems 7 Equipment. One volume is revised each year, ensuring that no volume is older than four years. In relation to the committees previously mentioned, TC 5.10 is responsible for Chapter 34 (Kitchen Ventilation) of the ASHRAE HVAC Applications Handbook, which was last revised in 2019. The chapter focuses primarily on kitchen ventilation systems in restaurants and institutional food service facilities. Brown and Miller provided content and graphics about demand control kitchen ventilation (DCKV) systems and variable frequency drives. In addition, for other handbooks, they have provided content on HVAC test and balance commissioning.
  • For further professional development, the Melink employee-owners have attended ASHRAE’s conferences. “Normally we meet biannually for a few days in conference settings, but we have a few virtual meetings in between to vote and discuss topics that are requiring attention in the industry,” said Brown.

Maintaining Perspective (For a Better Future)

Posted on by melinkadmin

Colleagues, Team Members, Friends, and “Family”:

Global pandemic.  Divisive rhetoric.  Recession.  Systemic racism.  Civil unrest.  Climate change.  On their own, each issue represents a monumental challenge for the United States of America — let alone the global community.  Yet, here we are, faced with the totality of these seemingly insurmountable problems. As with any challenge we are faced with, we have a choice to make: Lay down and surrender.  Or, stand-up and find a solution. But nothing can change without first changing our perspective.

Despite the perpetual drumbeat of bad news, we must be intentional and work hard to maintain perspective. For without it, we are subject to become victims of circumstance, insecurity, desperation, and anxiety. Reason yields to emotion. Our thoughts become overwhelmed and critical thinking, cloudy. Therefore, let us seek perspective.

  • Historical.  For nearly 250 years, America has persevered from one crisis through to the next:  war, depression, pandemic, natural disaster, gun violence, etc.  Has it ever been easy?  Certainly not.  The night is darkest just before the dawn.  Though it may be challenging to see, we will emerge stronger than ever before. 
  • The COVID-19 pandemic is a public health crisis.  In incredibly short order, we have made massive societal adjustments to manage the impacts.  The growth clip of the pandemic is slowing.  And there is a tremendous amount of investment, research, and development, with some of the best minds in the world, working to minimize and hopefully eradicate this disease. 
  • These are times of divisive rhetoric, a crisis of culture.  Fortunately, 2020 is an election year.  Soon we shall have a meaningful opportunity to exercise our vote and drive whatever change it is we want to see.  Debates on social media will only get us so far.  Elections matter.  Vote.
  • We are in a recession, an economic crisis.  Businesses are re-opening and people are getting back to work.  The impetus of this recession was an unpredictable, catastrophic event, not part of a normal cyclical downturn.  Our new normal may be different, but consumers will consume.  Things will get better.  
  • Systemic racism is, at its core, a crisis about the soul of our society.  We, along with many of you, are disturbed by the injustice that plagues our country.  Clearly, the national conversation has been elevated and this problem is being given the attention it so desperately needs and deserves.  In the spirit of seeking a better world, for ourselves, our children, and grandchildren, we pray that these events shall not go by in vain.  Rather, that as a nation we may fulfill the concept of ‘Equal Justice Under the Law.’ 
  • Prior to the pandemic, the cause, risks, impacts, and remedies of climate change were beginning to garner regular mainstream media attention.  This is a crisis in slow-motion that will hit public health, the economy, culture, society, and most certainly human rights.  The good news is not that the tide is turning – it has turned.  For the first time in 130 years, renewable energy production in the United States has surpassed coal.  And more electric cars are being sold than ever before.  We have a long, long way to go to stave off the worst impacts of climate change, but this is progress; net-zero energy is coming.  Through our continued innovation and deployment of energy efficient and renewable energy technologies and services we will continue transforming the world.

Still yet, you may remain daunted by the scale of these issues. If so, we offer the following actionable items, to put into perspective. First, as a reminder, maintain perspective and look for the good.  Do not be naïve, but staying positive requires choice, intention, and critical thinking. Second, carry your world on your shoulders, not the world. That is, to say, do not worry about things beyond your control. Someone once said worry is interest paid on trouble before it comes due. Your resources are limited. Focus them in areas where you have control and, or influence. Similarly cut out the noise. Seek truth when you absolutely need to be but be judicious in so doing. Apply yourself where and when it matters most. 

Finally, beyond their respective magnitude and impact, I believe each of these issues has one more critical attribute in common:  they are incredibly complex. We cannot solve them if we remain entrenched and endeavor for our perspective “side” to win.  We can and will continue solving complex issues if we remain open minded, empathetic, collaborative, and firmly commit to a better future. 

To our children, and grandchildren,

Energy Efficiency & Renewable Energy: Fighting Climate Change with a One-Two Punch

Posted on by melinkadmin

To invest in energy efficiency or renewable energy? A question often pondered by building owners, design engineers, investors, energy engineers, performance contractors, and anyone in between who has a say deciding how to invest money to make the strongest financial and environmental impacts. In an ideal scenario, one can invest in both efficiency and renewable energy.

Integrating Efficiency and Renewable Energy

When it comes to the materials we use in everyday life, we have all heard the phrase “Reduce, Reuse, Recycle.” Well, there is a reason why reduction is mentioned first! It can be argued that the most sustainable energy source available is the energy that we never have to use.

Of course, there will always be energy used no matter how efficient a building is. But, in the energy spectrum, renewables reduce the cost for the electricity that must be used. Renewables also offer many other benefits, such as protection against fluctuating energy costs, incentives like federal tax credits, net metering, shaded parking lots… the list could keep going. And research confirms that investing in both energy efficiency options and renewable energy is a smart move. The American Council for an Energy-Efficient Economy (ACEEE) and the American Council on Renewable Energy (ACORE) collaborated in a 2007 study, reporting that investments in both energy efficiency and renewable energy are essential for the United States to create a secure energy future.   

Boxing gloves

Creating an Energy Synergy

Think about it like this… If a boxer has a great right hook but a poor defense, he may win some fights but could easily lose to an opponent with a solid defense and a timely counterpunch. Combining two strengths to be stronger overall is called synergy. That is when the whole is greater than the sum of the parts. When energy efficiency and renewable energy are combined, they complement each other in a way that can maximize the total impact, both environmentally and economically. Consider this…

Right hook: An upgraded utility plan to reduce HVAC costs.

Left jab: Intelli-Hood®, Melink’s demand control kitchen ventilation system to further reduce HVAC costs.

And for the knock-out uppercut: A solar array made of super-efficient photovoltaic modules that meets the entire energy load of the building (taking into account the reduced energy usage from the previous energy efficiency measures).

And what’s even more of a win? By reducing the facility’s entire energy load, the upfront cost of the solar array is reduced. Plus, the quick payback as a result of the energy efficiency measures creates additional cashflow to help pay for a renewable energy source, like solar array (or even geothermal!).

Accounting for Energy Opponents

But what if? Let’s say that the uppercut was blocked in this scenario because, in many cases, the availability of renewable energy is limited due to geography and available space. For example, in the hills and valleys of Southern Ohio, wind energy is not going to be near as effective as compared to the plains of Northwest Texas.

Or, while solar performs well in Ohio, a building could have very limited space for an array. For the counterpunch here, one could implement new energy efficiency technologies and maximize efficiencies on existing equipment. Then, for the knockout, a smaller solar array like a parking canopy could still be very impactful.

The bottom line? There are many options at play when it comes to the powerful combo of energy efficiency and renewable energy. Together, this combo helps to reduce peak demand charges, which can be astronomically higher than off-peak charges. For example, if a new energy-efficient HVAC system is added to an office building, that building will still see high peak demand charges (although lower than before the upgrade) from the utility. However, capturing a renewable energy source, like wind or solar, can greatly reduce the impact of peak demand charges.

International Women in Engineering Day

Posted on by melinkadmin

Now in its seventh year, International Women in Engineering Day (INWED) is celebrated annually on June 23. The day celebrates the accomplishments of women engineers and raises awareness of career opportunities.

Currently, Melink Corporation employs four female engineers.

“Our goal is to enrich and strengthen our teams with a more diverse workforce that can lead to better innovation and effective leadership, while improving our company’s overall performance,” said Angela Bradley, Melink Corporation’s Director of Human Resources.

Sarah Evans

Embedded Software Engineer

Degree: BS Computer Engineering

As an engineer at Melink, my job is to take the ideas for what we want PositiV® or Intelli-Hood® to do and implement them. Since I started working at Melink, my main focus has been on PositiV, our building health monitor system. My work includes programming the PositiV devices, maintaining an application for setting up the devices, collecting and analyzing data, and testing. While all these tasks involve software development, each problem is unique and can require a number of different solutions. Essentially, my day-to-day includes solving puzzles, which I really enjoy.

Krysta Kincaid

Sales Engineer

Degree: BS Industrial and Systems Engineering

My day-to-day in sales at Melink is not necessarily predictable, and for that I am grateful. I support the sales team by creating test and balance proposals and managing projects for new customers. The majority of my time is spent evaluating mechanical plans and developing potential scopes to create proposals for prospective customers. When we win the project or program, I run point with the end customer and site contacts. This includes reviewing the contract, scheduling our technician with the jobsite, securing rental equipment, communicating with our technician on site, distributing any necessary information to the customer in real time, and ensuring the customer gets the final report. I will then help answer any questions the customer has about the findings. In my role, I collaborate with almost the entire sales, national account, and network leadership teams on a daily basis. I truly enjoy the human interaction with my colleagues, as well as our customers. At the end of the day, all of our efforts at Melink go toward trying to save the environment, and that gets me out of bed every morning.

Katherine Moeller

Quality Assurance Engineer

Degree: BS Industrial and Systems Engineering

My role in quality assurance is to ensure that the products Melink produces, as well as our internal processes used to create those products, function properly and efficiently. Daily, my role can vary from creating process documentation to testing firmware to verifying data accuracy. I help connect what is created by the product development team to something that can be replicated easily by our production team. I support the production team by providing the materials they need to create and test a high-quality product, prior to sending it to the customer. Something I really enjoy about my job is that each day is different and I get to work with multiple stakeholders across the company.

Anna Rusconi

Account Engineer

Degree: BS Mechanical Engineering

My role varies from day to day. When we receive a test & balance quote request from one of our national accounts, I look through the mechanical prints to prepare a quote. The quote covers the scope of work for the visit, as well as the estimated time needed for an on-site technician. Before our technicians visit on site, I make sure they are equipped with all the information they need to successfully complete the job. If the technician has any questions while on site, I work with them and our site contacts to ensure the visit goes as smooth as possible. Once the T&B is completed and the final report is sent to the customer, I will work with the customer to help them understand the information. We provide our customers with an overview of their project data; I work with the National Account Manager to pull data to present to the customers. I really enjoy this position because each day is different, and it is rewarding to help the customers and the internal team. 

About International Women in Engineering Day

INWED was launched in the United Kingdom in 2014. Since then, the day has grown significantly and was recognized by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2016.

Intelli-Hood in the Indian Market

Posted on by melinkadmin

Melink’s Intelli-Hood® demand control kitchen ventilation (DCKV) system has long been a global product. But, more recently, we introduced Intelli-Hood in the Indian market.

Developing a New Market

We have officially been working in India for 2.5 years now, but it is still a fairly new and developing market for us. Introducing a company into an already mature market with similar products is very challenging. It takes attention, care, and a product that adds more value than its competitors’.

Before committing to the Indian market, we did our homework. We researched the competitors, key differentiators, competing products, and how we could best offer customer support. We put ourselves in our customers’ place to really understand their needs so that we could ensure we had a valuable product and support team that could help them meet their goals.

If we felt our customer service would be compromised by distance or communication barriers, we would not have entered this market. Melink Corporation prides itself on being a customer-focused service company. From the beginning, it was important to have someone on the ground in India to speak with customers, visit sites, and work with the home office in the United States. (That’s where I come in!)

Speaking of the home office, a critical component to entering the Indian market has been the support of the Intelli-Hood’s U.S. team. They have worked continuously with promptness to provide all the technical details that our customers need, which is the biggest boon to earn customers’ trust. I am really thankful for all the team members who supported the launch of Intelli-Hood within my region. Together, we are bringing an end-solution to save energy in our global environment.

Early Success in India

Because of all the behind-the-scenes work to enter the market, we have seen success.

One of our biggest Indian projects that has been successfully retrofitted with Melink’s Intelli-Hood system is a project in the operation kitchen of a large resort. The kitchen contains all kinds of cooking appliances to prepare food for different cuisines, like Indian, Chinese, Italian, etc. For almost a full year, we have continuously monitored the system from Day 1 of installation and commission. With these real-time result readings, we were able to prove the benefits of our product in regards to energy savings and return on investment, which has paved the way for the approval of many other projects.

Here are examples from this project. You can see the energy savings:

Main Kitchen – Fan Speed Profile
1/1/2019 to 12/31/2019
This kitchen includes five hoods and two exhaust fans. With Inteli-Hood, the customer gained an electrical savings of 1,17,496 kwH/year.

Secondary Kitchen – Fan Speed Profile
1/1/2019 to 12/31/2019
This smaller kitchen includes two hoods, one pizza oven, and one exhaust fans. With Intelli-Hood, the customer gained an electrical savings of 25,077 kwH/year.

Based on this information, we are working with the client to analyse more data to help them to be more energy efficient and to lower their operating costs.

What’s Next for Melink in the Indian Market?

Moving forward, we are working with our partners to customize Intelli-Hood system designs to meet their site requirements. We look forward to future projects in existing kitchens (retrofits) and also new projects spread across Asia.

If you have a project in India and would like to learn more about Intelli-Hood, please contact me. I live and work in India full-time, and I would welcome the chance to introduce you to Melink’s products. Email me at [email protected].
