Indoor Dew Point: Maintaining Thermal Comfort, Avoiding Building Damage

Posted on by Lindsey Burbee

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.

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 Lindsey Burbee

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).

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.

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

Posted on by Lindsey Burbee

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.

Winning the Fight on Climate Change

In summary, combining energy efficiency and renewable energy delivers the greatest environmental and economic benefits. Melink Corporation can help building owners, engineers, and designers with both energy efficiency and renewable solutions. We know this combination works from experience, too. With our own Zero Energy Building and another LEED Platinum building, Melink does not just talk the talk, we walk the walk.

Maintaining Perspective (For a Better Future)

Posted on by Lindsey Burbee

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,

International Women in Engineering Day

Posted on by Lindsey Burbee

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.

Meet Melink’s women in engineering…

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.

Becoming an Intelli-Hood Sales Engineer (During a Pandemic)

Posted on by Lindsey Burbee

 

Sales Engineer. These are two words that most of us have a clear understanding of their respective meanings. But what about when they are put together? Well, I ‘m not sure what to expect either, but it sounded like a challenge, and I like those. I’m new to the Demand Control Kitchen Ventilation (DCKV) industry but well-versed in technology and mechanics due to my background. So, when I took the role of a Melink Intelli-Hood Sales Engineer, I felt well prepared.

Then, enter COVID-19. 

Onboarding plan? Derailed. Customer visits? Cancelled. Installations with field service techs? Not attending. How was I supposed to embrace my role and be a valuable addition to the team? 

What Next?

That’s where my Melink family stepped in. To continue with business “as normal,” we, like other companies, took advantage of virtual meetings, trainings, lunch-and-learns, and other digital tools. These tools were not thought about or utilized even just 10 years ago! As the pandemic unfolded, our work progressed, thanks to these digital tools. I immediately saw the value in my new role and Melink’s value to their customers.

For instance, indoor air quality became a topic of daily conversation. Essential facilities, like grocery stores and hospitals, were now on the front lines. I helped get Intelli-Hood® kitchen ventilation controls into these areas and ensured first responders had healthy air.

You see, Intelli-Hood learns to optimize your kitchen ventilation by using temperature probes paired with infrared optical sensors. The optics pick up on airborne contaminants in the form of smoke and then trigger the variable frequency drives. The exhaust fan’s variable frequency drive (VFD) adjust to the appropriate speed to ensure adequate evacuation of the effluent. Smoke being present does not have to mean that heat is, which is one more way that a Melink Intelli-Hood control system ensures continuous capture of all effluent. As if that was not beneficial enough, the system is also ensuring that more of the pre-conditioned air is staying in the occupied spaces instead of being wastefully exhausted from the kitchen due to continuous discharge ventilation.

Melink Intelli-Hood System

Looking to the Future: Customized Solutions

Pre-COVID-19 and now, I spend each day as a Sales Engineer building customized quotes for our customers’ unique needs. As requests for new construction sites roll in, I work with my Business Development Manager to go through the plans for each site, reviewing the kitchen designs and ventilation requirements, as well as requirements that have been called out by general contractors and food service consultants. Every job requires different exhaust hood types; fan types and horsepower; and temperature monitoring preferences, as well as the possibility of tying the system into a building’s BACnet. All of these items and more are taken into consideration when preparing an accurate, customized quote for our customers.

Thus, these last few months of working in Virtual Corporate America have helped me realize just how adaptable our team at Melink — and our Intelli-Hood controls — really are. COVID-19 or not, these control systems are improving the health and wellness of employees and customers in thousands of locations worldwide, all while being the most energy efficient DCKV system on the market. And the umbrella of Melink solutions extends to other areas, too. When you pair an Intelli-Hood control system with solar panels, a PositiV® unit to monitor building health, and a high-quality Test and Balance plan, you really cannot ask for a more efficient and energy-saving space.

I may only be finishing my first quarter here at Melink as a Sales Engineer, but already I have felt the satisfaction of knowing that what I am doing is making a difference.  We really are making the world a better, greener place, one building at a time.

Intelli-Hood in the Indian Market

Posted on by Lindsey Burbee

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.

Intelli-Hood in Asian Market Case Study example 1

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.

Intelli-Hood in Asian Market Case Study example 2

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].

How Restaurants Can Verify Proper Ventilation for Health & Comfort

Posted on by Lindsey Burbee

If you have owned or operated a restaurant, you are familiar with the challenges of maintaining proper airflow throughout the building. From the kitchen to the front of the house to the back of the house, proper airflow can be challenging to keep in balance. That said, restaurants go out of balance for many reasons, wreaking havoc on a building’s health, comfort, and ventilation.

Does your restaurant look like this?

Restaurant Ventilation Problems

Unfortunately, these types of issues are extremely common in existing restaurants throughout the United States, and, when left unaddressed, can lead to negative building pressure, which causes serious long-term damage, poor indoor air quality, poor energy efficiency and uncomfortable conditions.

What are the industry guidelines for building ventilation?

ASHRAE 62.1 outlines minimum ventilation rates for various types of buildings, as well as other measures to ensure acceptable indoor air quality (IAQ) for human occupants.  In a nutshell, ASHRAE recommends a certain minimum amount of fresh outside air be introduced through the building’s HVAC system.  It also recommends that the proper amount of outside air be verified at least every five years. Without properly setting the outside air intake volume, buildings can experience negative building pressure and exhibit sick building characteristic. The best way to verify outside air is to hire a certified Test & Balance company, such as Melink, which has the proper air measurement instrumentation and years of experience.

How can I tell if my restaurant is properly ventilated?

  1. Observe restaurant conditions and ask staff for a log of comfort issues
  2. Turn on HVAC equipment, “Fan On” mode
  3. Check the front door for signs of negative building pressure
  4. Observe the kitchen hoods for proper smoke capture
  5. Check the restaurant for drafts
  6. Inspect the rooftop equipment to ensure it is in working condition
  7. Ensure your HVAC preventative maintenance services are being performed satisfactorily
  8. Contact Melink for building balance and comfort investigation services

How can I be sure my building stays healthy, comfortable, and properly ventilated for the long-run?

More and more restaurant chains are interested in the idea of “ongoing commissioning.”  With scant facilities budgets and facilities managers stretched ever thinner, it is not feasible to routinely send someone to each facility to verify building health, ventilation, and comfort. Out of this necessity, Melink’s PositiV® Building Health Monitor was born. PositiV is a standalone system that monitors your building’s pressure and remotely tracks building health. Alerts are sent when the system detects anything is out of set parameters. Moreover, PositiV monitors temperature, relative humidity and CO2 so that you gain a full picture of the health of your facility. 

Melink PositiV Building Health Monitor

PositiV is THE solution toward being able to actively monitor restaurant health, comfort and ventilation for the long-haul, and it is the most affordable way for multi-site facility managers to proactively stay ahead of building health issues before they become big facility problems.

Below is a REAL restaurant’s PositiV data. The site is taking action to improve negative pressure and building ventilation issues before they cause building damage, mold and comfort problems.

Melink Volunteers: Green Business Groups of Cincinnati

Posted on by Lindsey Burbee

Supporting green business groups and clean energy initiatives is important to Melink as a company, and many employees have made a personal commitment to such initiatives as well. Melink employee-owners donate their time and expertise to serve on sustainability groups, advisory board committees, or professional boards at the local and regional levels.

Green Business Council of Cincinnati 

Joel Geiman, General Manager
Allison Sternad, Director of Marketing & Sustainability

The Green Business Council of Cincinnati (GBC) was founded in 2011 by several Cincinnati area corporations to help local business leaders collaborate on sustainability initiatives, such as energy benchmarking, waste management, and composting. The council meets on a bi-monthly basis to help guide its members to apply best practices for delivering a better social, economic, and environmental future. Melink employees not only offer their expertise on renewable energy and LEED building certification but also share their experience with their own internal sustainability programs.

Melink is also part of the GBC Executive Committee, which meets on a monthly basis. “Melink’s responsibility on the committee is to manage the list of all council members, keep members accountable on attendance requirements, and to help set expectations for new members in the GBC’s mentorship program,” said Geiman, who has been volunteering his time with GBC for about a year.

GoZero Compost Collection at Melink Corporation

GoZero is a Cincinnati non-profit that provides food waste collection and compost delivery services. Its main goal is to divert food waste from landfills as a self-described “compost courier.” Essentially, GoZero organizes residential and commercial drop-off sites for food waste collection, picks up the waste, delivers it to a site to be composted, and then delivers the cured compost once ready for application. Melink has had a GoZERO food waste compost drop-off station on its campus since 2016. Area residents can subscribe to get a collection bucket and start dropping off food scraps from home.

Nate Schmidlin, Account Specialist

EV Cincy is a project out of the City of Cincinnati’s Office of Environment and Sustainability. Increased adoption of EVs reduces local air pollution, improves public health, and slows climate change. Schmidlin serves as an ambassador to educate others about the benefits of electric vehicles. However, due to the pandemic, original outreach plans like going on test drives are on hold.  “COVID-19 has forced us to switch gears from our original outreach plan. Now it’s all about getting the EV awareness message out on social media to help people stay informed,” said Schmidlin.

Why LEED Buildings Make Financial Sense

Posted on by Lindsey Burbee

The University of Notre Dame chose sustainable, LEED-approved construction options and why you should, too.

Recently, the United States Green Building Council (USGBC) awarded the University of Notre Dame with LEED (Leadership in Energy and Environmental Design) Gold certification for the design, construction, and operation of three buildings attached to Notre Dame Stadium. These building are Duncan Student Center, Corbett Family Hall, and O’Neill Hall. Your next statement may be “So what?!” Why should the folks at Notre Dame care, and why should anyone else involved with owning, managing, and operating a commercial building care?

The answer? Money.

According to research from the U.S. Department of Energy, LEED buildings consume 25% less energy and 11% less water than non-LEED buildings. That translates to lower utility bills. If you could build the same facility but pay 11-25% less in operating costs, why would you choose otherwise? And this isn’t even taking into account all the environmental benefits of LEED buildings!

If the decision is made for the non-LEED option, then that is saying you know you could spend less operating this building, but you want to pay more. You know you could improve the income flow of your building, but you choose to make less. Why? 

LEED Buildings: Financial Common Sense

Perhaps the concern is that a LEED building might cost more to construct than a non-LEED building. Depending on where you are building, there are notable tax benefits and incentives from states and municipalities (AKA free money). Choosing to build a non-LEED building is essentially saying you don’t want free money.

Finally, since a commercial building is an investment, the core factors of occupancy rates, lease payments, and long-term tenants are very important to cash flow. Citing the USGBC, LEED buildings retain higher property values than non-LEED buildings. LEED buildings are healthier for the occupants, and 79% of employees say they would choose a job in a LEED building over a non-LEED building. All of these point to greater demand (occupancy), longer term leases, and higher property appreciation. Money, money, money.

Intelli-Hood: A Solution for LEED Buildings

As I write this from Melink’s own LEED Platinum-certified headquarters, nicknamed HQ1, and across the street from our newly opened HQ2, which is a Zero-Energy Building, I am very happy for Notre Dame. I am also very PROUD that Melink’s Intelli-Hood® variable speed kitchen hood controls were a part of all the conservation measures that helped them achieve this certification. Within the three buildings that achieved LEED status, Intelli-Hood was installed on eight kitchen hoods. Intelli-Hood is now standard on any new hood installations, as well as retrofits, at Notre Dame.

Notre Dame opted for the sustainable, energy efficient, and financially smart option of LEED construction. What will you choose?
