Is the Coronavirus Affecting Climate Change?

Internationally, the coronavirus has impacted many aspects of our world, from the economy and spending habits to our jobs and everyday routines. But what about our climate? Our ecological environment has been largely affected by COVID-19, as well.

 

 

Decreased Greenhouse Gas Emissions

While COVID-19 has spread globally, governments have initiated social distancing and stay-at-home orders in efforts to stop the spread. The lockdowns caused many industries and individuals to cease production and travel. Thus, causing a ripple effect in greenhouse gas emissions. Countries across the world are experiencing a drastic drop in greenhouse gas emissions, according to an article from the BBC. In fact, China experienced a 25% decrease in CO2 emissions. In the United States, New York has seen a decrease as low as 50% in CO2 emissions. Other major countries seeing similar decreases in CO2 and NO2 emissions include Italy, Spain, and the United Kingdom.

While this decrease appears to be some much-needed good news during the pandemic, scientists and ecological specialists are skeptical that these drops in emissions are going to have any lasting effects. If these drops in emissions are caused from a decrease in manufacturing and travel, then what will happen after the virus has been contained, when production increases and daily travel routines return?

“The fight against pollution is a long-distance race, not a sprint,” said Xavier Querol, a science researcher specialized in atmospheric pollution. Essentially, this means the sudden drops in emissions happening across the globe are temporary and if we truly want to see a lasting positive effect in greenhouse gas emissions, we must look to other solutions.

 

 

A Closer Look at Energy Consumption

The majority of greenhouse gas emissions (72%) can be attributed to energy. Of that 72%, the manufacturing and transportation sectors together make up 27.7%, which is the main contributor to the decrease in greenhouse gas emissions that are being experienced around the world due to COVID-19 restrictions.

 

However, it’s not feasible to assume emission levels are going to remain where they are once COVID-19 restrictions are lifted. Therefore, we must look to the highest contributor of energy consumption, which is electricity and heat, and find solutions to decrease emissions.

Currently, there are multiple companies creating technology to support the goals of lowering emissions, slowing climate change, and lowering energy consumption. Melink Corporation is a leader in Zero-Energy buildings. Melink offers five energy solutions to create healthy buildings and decrease energy consumption:

 

Each of these services help create a sustainable world for future generations. They also serve as cost-saving opportunities for businesses to implement.

 

 

Coronavirus and Climate Change

In summation, what’s COVID-19 teaching us about decreasing climate change? Well, that’s a loaded question that cannot be answered fully. But the solution starts with decision makers, business owners/operators, and individual consumers. If any good comes from this pandemic, maybe it’s how our perspective is changing. Now, more than ever, we see the importance of preserving this world. This can be accomplished through maintaining our current environment and ensuring future generations are set up for success. We can improve when it comes to climate change, whether coronavirus is in the picture or not.

Why Positive Building Pressure Matters

Can a building get sick? I’ll give you the answer up front: Yes, sure, most definitely — a building can get “sick.” You may ponder… “But how can a building become sick? It is an inanimate object. It doesn’t live and breathe like humans!” On the contrary, your building is a living object. The main factor making your building come alive is its people: your customers, employees, and outside partners (think mail delivery or an overnight cleaning crew). Let’s dive into what factors can make a building sick and why maintaining positive building pressure is so important in prevention.

 

 

What Makes a Building Come Alive?

First, consider what may make your building come alive (or ultimately “infect” it):

 

  • Supplies
    The products you bring in (from any point of origin) may have outside contaminants or be perishable. As you know, perishables may emanate odors or fumes.
  • Chemicals
    You must account for chemicals or cleaning supplies in their controlled rooms (where exhaust is extremely important).
  • Restrooms
    Consider the restroom facilities. Restrooms, especially those open to the general public (i.e. in a lobby area) can encounter high volumes of traffic and behaviors that may not meet sanitary standards.
  • HVAC System(s)
    Your HVAC system is a key element bringing your building to life. With proper cleaning and maintenance, they are designed to provide comfort on demand. Heating and cooling are crucial amenities that have grown to be a must-have and are mandated by federal and local guidelines.

When you take all these factors into account, it’s easier to understand how a building can become “sick.”

Facility Managers: How to Prevent Sick Buildings

So how can a facility manager or building owner help to prevent sickness in a facility? As a professional in the HVAC industry, my primary goal is to earn your trust to maintain the wellness of your building’s HVAC system. Think about it — you can’t control others’ actions. There is no way to determine someone’s state of health as they are in your establishment. But you can control the HVAC system and make sure it is properly maintained to be a healthy system!

A little-known fact about HVAC systems that I will stress the importance: FRESH OUTSIDE AIR IS NEEDED TO MAINTAIN A POSITIVE BUILDING PRESSURE AT ALL TIMES. What does this mean, and why is it important?

 

  1.  Your restaurant, retail store or office building, has many moving parts to bring it alive, has to breathe. Like any living thing, it requires oxygen to replace the carbon dioxide. The equation should result in bringing in a greater amount of fresh air than the carbon dioxide, chemicals, fumes/odors, and cooking effluents that the building creates. When this happens, there should be a slight positive pressure from the inside of your establishment that pushes outward at your doors and drive-thru windows.  A proper HVAC test and balance (TAB) by an NEBB-Certified firm like Melink can help you achieve this goal.
  2. A common oversight that people make is assuming, “My building is positive. We’re in good shape.” But how sure are they that the lungs of the HVAC system are clean and free of operational damages? Many times, I have encountered damaged and clogged filtration components within an HVAC system that may lead to costly repairs to your equipment and structural damages:

 

  • Clogged or missing outside air intake filters

  • Inadequate or missing air filters

  • Dirty evaporator and condenser coils

  • Clogged blower wheels

  • Mold, mildew, or biological growth

  • Contaminated ductwork

  • Even small animals trapped inside components

 

 

Checking HVAC ductwork for positive building pressure

 

All these issues work together to
create a sick building.  The opposite of
positive pressure is that dreaded negative pressure. Every time your facility’s
doors open, all of the outside air conditions are sucked into the
building.  These elements can be hot or
cold air, humidity, airborne pathogens, and odors. The humidity attaches to the
chilled supply diffusers and grilles, creating moisture buildup that drips onto
your floors, tables, customers, and clients.

 

 

Checking HVAC filters for positive building pressure

 

Of course, it’s not feasible for a facility manager to know the ins and outs of every HVAC system of every facility he/she manages. So let us do the work for you! Melink Corporation’s T&B technicians can be your eyes and ears to help your facilities maintain positive building pressure. We are an army of application engineers with skilled LEED and NEBB certifications. Our company is nationwide and has more than 30 years of experience. Along with services that will help you on your way to a healthy building, we offer a monitoring system and demand ventilation systems that will alert you when problems or concerns arise.  These services, along with reliable routine maintenance will minimize uninterrupted service to your most important people. We can help you protect your customers, employees, and outside partners from sick buildings.

COVID-19 Closures: Mitigating Damage to Unoccupied Buildings

Dealing with COVID-19 Closures

Many U.S. states are working to flatten the curve as businesses are impacted by COVID-19 closures. The “stay at home” or “shelter in place” orders have limited human interaction in attempt to prevent spreading the virus. Additionally, many companies across the country opted to temporarily close facilities, preventing employees from contracting the disease. With shutdowns it’s become increasingly difficult to determine a facility’s condition, or to repair any issues developing while the facility is unoccupied.

Damage to Unoccupied Buildings

Consider these scenarios that could arise in an unoccupied facility…

Humidity

 

  • Buildings in coastal regions may experience high humidity that goes unnoticed, which can in turn lead to mold growth. Imagine if the facility is a retail store. The end-result might mean thousands of dollars of damaged, unsalvageable clothing merchandise.
  • Think about a restaurant or bar. There may be hundreds (or thousands) of dollars of alcohol in stock, going untouched through the COVID-19 crisis. Corked bottles of wine are not exempt from the effects of dry indoor air. Extremely low humidity levels can slowly chip away at a cork, leaving room for air in the bottle and ruining the flavor. The ideal humidity level for wine storage is 60%.
  • Another thought for restaurant facilities: A humid environment allows mold growth to fester. The COVID-19 shutdowns began suddenly for many facilities. Did kitchen staff have adequate time to scrub walk-ins, pots, and pans? Were grease traps thoroughly degreased? These are potential breeding grounds for mold during non-occupation.

Moisture

  • If indoor moisture levels drop too low — like cooler climates that are shifting from winter to spring temps — wood can begin warping. For instance, wooden window frames can shrink, making them difficult to open. This can potentially create gaps that let in cold, dry air.
  • Low indoor moisture can also lead to peeling or separated wallpaper and cracked paint on plaster walls. What if you returned to your facility, only to realize you’ll need professional painting or remodeling services?

Mulit-Purpose

  • Contemplate multi-purpose facilities, like an apartment complex with retail or dining space on the first floor. Completely shutting down HVAC airflow to unoccupied businesses could lead to uneven air flow and temperatures throughout the larger building.

The bottom line: Scenarios like these will go unnoticed and unrepaired until employees return to their facilities. Only then will they uncover the damage caused by an unoccupied month.

 

 

Preventing Facility Damage During COVID-19 Closures

While these issues seem frightful, many state governments have kept issues like this in mind when mandating shelter-in-place orders. Seeing value and necessity in essential services, many states are allowing skilled trades such as HVAC technicians to continue working. During quarantine, let technicians be the eyes and ears at your facilities to ensure critical issues didn’t develop, and further delay reopening.

In addition, this downtime can also be the ideal occasion to have technicians visit the facility to address any known issues or to perform preventive maintenance. Maybe there is a repair the facility manager has been putting off because its fix requires closing a typically busy corridor or lobby area. By addressing this work now while the facility is shut down, managers can limit future downtime, employee inconvenience, and lost profit.

And as a preventative measure for the duration of this closure or in preparation of future closures, consider installing sensors to remotely monitor a facility’s indoor air quality levels through relative humidity, temperature, building pressure, and CO2 checks. A system like Melink Corporation’s PositiV® building health monitor can remotely track and trend building health, plus send alerts to the facility owner or manager when the system detects measurements outside its set parameters. While a facility may not have this in place to combat the current COVID-19 closures, it can be installed now to prepare for future unplanned closures or even a vacation (Facility managers need a break at some point, right?!).

Coronavirus & Indoor Air Quality

Now, maybe more than ever, many businesses are concerned about indoor air quality (IAQ) to protect employees and customers from coronavirus. With the current spread of COVID-19 across the globe, it is important that we are all taking the necessary steps to reduce the spread of the virus. As part of this, it is important to recognize how your HVAC system can impact your IAQ during long hours of social distancing, as well as steps that can be taken to limit the spread of the virus in buildings.

In a normal year, the typical American spends 90% of his or her time indoors. With current guidelines about social distancing, this number is expected to increase over the next few months. Prior to recent events, the American Medical Association stated they believe 50% of illnesses are caused, or aggravated, by polluted indoor air. Furthermore, per the EPA, indoor air contains two to five times more pollutants than typical outside air.

So what does this mean for the COVID-19 crisis? Now that we have learned the novel coronavirus can be spread via airborne transmission when in close contact, there is the possibility that the HVAC system could cross-contaminate. That means air from an infected person could recirculate through a facility’s HVAC system and infect another individual. An example of this is how cruise ships experienced severe outbreaks. All cabins share an HVAC system, which is working as a mode of transmission from one individual to another.

While this risk of shared indoor air cannot be completely eliminated,
there are a few items that can be addressed to reduce the potential for
transmission through the HVAC system including:

 

  • Enhanced Ventilation & Ventilation
    Effectiveness
  • Source Separation
  • Air Filtration
  • Operable Windows

First and foremost, facilities should ensure their HVAC
equipment is bringing in the correct amount of outside air required by the
engineered designed plans, as well as managing the pollution and exhaust from
your building properly. To further mitigate this risk, one should attempt to
increase the percentage of outside air being brought into a facility to a
higher percentage than minimally specified. In doing this, the equipment will
reduce the amount of air being recirculated through a building. This will not
only reduce “shared air,” but will also decrease levels of CO2 and other indoor
air pollutants that can create an uncomfortable, or unhealthy, facility.

For a residential facility, where air source isn’t as easily controlled, it can also be helpful to open windows to bring in fresh air to any given room. In addition, it is worth verifying that any fresh air being brought in is being evenly distributed. If it isn’t, certain rooms may have less air turnover, meaning that the air isn’t circulating in and out of the facility properly.

The next few months may be difficult with longer hours than normal spent indoors. It is important that we are all taking steps to minimize the spread of coronavirus and other airborne illnesses both now and in the future.

How Do Seasonal Changes Affect Building Health?

Seasonal Changes and Building Health

As we transition from dry, cool winter months to hot, humid summer, you may be saying, “Woohoo! Bring on the heat!”. However, seasonal changes can affect building health. Specifically, the summer season presents major problems for facility managers and building owner. This is because their buildings’ HVAC systems struggle keeping up with increasing cooling loads and extremely humid outdoor air.

Just as spring plant life sprouts, HVAC mechanical issues can pop up with warmer temperatures. Poor indoor conditions, like high indoor relative humidity, negative building pressure, CO2 buildup, and temperature fluctuations are some examples.

Staying ahead of these issues before they become noticeable, costly problems is crucial when considering the overall health of your building and its HVAC systems.

 

 

Humidity: A Common Seasonal Issue

At various facilities, a common issue that comes with changing seasons is humidity. Specifically, humidity can be difficult to maintain at a comfortable level.

 

 

Condensation on building window, a seasonal building health issue.
Condensation in office building

 

In the winter, the heating mode on air handling equipment can heat or evaporate the existing moisture in the air to reduce the overall relative humidity as outdoor air is brought into the building. However, in the summer, the opposite occurs: the air handling equipment cools the building space and doesn’t heat or evaporate the moisture out of incoming air. This combination of high relative humidity and indoor dew point ultimately creates conditions that promote condensation or organic growth within the facility.

 

 

A Year-Round Solution for Indoor Building Health

The most cost-effective solution to verifying and ensuring long-term indoor building health is with a sensor capable of measuring key building health metrics like differential pressure, relative humidity, dew point, temperature, and CO2.

 

 

Components of building health

 

By gathering data on building health metrics, the facility manager can quickly verify on-site conditions in real-time. As a result, they gain peace of mind knowing their buildings meet engineering specifications per design. In addition to these benefits, sensor data gathering gives users the ability to track and trend building health over a long-term period.

 

 

Using Data to Plan for Seasonal Building Health Changes

Getting and staying ahead of maintenance doesn’t need to start with expensive truck rolls and frequent site visits. Instead, sensor solutions provide inexpensive, effective avenues to implement proactive mindsets. Collected data can be aggregated into easy-to-use online portals, capable of summarizing, visualizing, and diagnosing issues on site. Allowing users, the ability to predict HVAC performance for a lasting solution.

Get ahead of the changing seasons by verifying your building is healthy today!

Air Quality’s Impact on Health

Indoor air quality (IAQ) can influence the cold/flu season. According to the American Medical Association, 50% of illnesses are caused or aggravated by polluted indoor air. The U.S. Environmental Protection Agency (EPA) believes this is because indoor air contains two to five times more pollutants compared to typical outside air.

While the average person spends 90% of their time indoors, many groups of people considered to be “high risk” spend even more time indoors. These populations include but are not limited to babies, the elderly, and those with health conditions. So when you consider the ample amount of time people are spending indoors with potentially polluted air, it is easy to understand how IAQ can be linked to sickness. In fact, IAQ poses such a large risk to human health globally that the EPA recognizes it as one of its top 5 health hazards.

 

 

Sick building showing indoor air quality

 

While most people think that poor IAQ is easily noticeable because they can sense it through vision or smell, this is not normally the case. Many times, the IAQ in a facility may be poor because the CO2 level is far higher than recommended. Typically, a “safe” level of CO2 is between 400-1,000ppm, but levels can reach as high as 2,000ppm. At this high level, occupants can experience headaches, sleepiness, decreased cognitive function, and increased heart rates.

To ensure that CO2 levels are kept in check, it is best to have a building health monitor (such as PositiV) installed to examine these levels. If the CO2 level is above the 1,000ppm mark, it is best to examine the outside air intake on the air conditioning equipment to ensure the facility is receiving the proper air changes per hour and enough fresh air is entering the facility.

Love Is in the Air (and So Are Dangerous Gasses)

With Valentine’s Day upon us, we can’t ignore the fact that love is in the air and all around. The season of love and Cupid’s magic are hard to ignore. Unfortunately, lovebirds, that isn’t the only thing you will find in the air this season. Dangerous gasses called Volatile Organic Compounds (VOCs) are lurking everywhere (up to 10 times higher indoors), and could be turning your stomach butterflies into nausea and vomiting.

VOCs include a variety of chemicals that are emitted as gasses from certain solids and liquids, including common household products. These are products that most people have around their house and place of business, such as paints, aerosol sprays, cleansers and disinfectants, hobby supplies, and even dry-cleaned clothing! Who knew? Items that may be littered around your space are known to cause both short-term and long-term adverse health effects including but not limited to irritation, nausea, liver and kidney damage, and possibly cancer. Scary stuff, right?

So how do you reduce your risk and exposure to these nasty gasses? First and most importantly, increasing ventilation when using these types of products is key. For commercial buildings, experienced HVAC engineers can ensure a building has enough air changes per hour to properly replace the indoor air with fresh outside air.  This measurement is determined by the building capacity, as well as how the space will be used. For example, by code, a restaurant requires an average of 20 CFM of fresh air per person, so if the max occupancy is five people, the building will require 100 CFM of fresh air at minimum to ensure a healthy amount of air changes per hour.

While this seems like a simple way to ensure a building’s air is not filled with common air pollutants including VOCs, this is not always the case. The amount of outside air entering the building is set by the rooftop unit (RTU) to match the designed value for the facility. This value is then verified through a test and balance technician measuring the airflow and resetting it to the proper amount. Without this final verification, your building may be receiving improper amounts of fresh air, which can leave your building and its occupants susceptible to higher concentrations of air pollutants.

Other steps to take to reduce risk in your home and business are:

  • Follow label instructions carefully. Always meet or exceed label precautions.
  • Throw away partially full containers of old or unneeded chemicals safely. Only buy in quantities you will use soon.
  • Keep exposure to paint strippers, adhesive removers, aerosol spray paints, auto exhaust, and tobacco smoke to a minimum.
  • Use integrated pest management techniques to reduce the need for pesticides.

Don’t let VOCs ruin the love for you this Valentine’s Day! Take the right steps to minimize your exposure and keep the magic of the season alive.

Melink Completes Zero-Energy Building at Super-Green Campus

FOR IMMEDIATE RELEASE

 

CINCINNATI, OHIO — Melink Corporation has completed construction of HQ2, its second Zero-Energy Building headquarters, at its super-green business park in Milford, Ohio.

The Melink HQ2 is a Zero-Energy Building (ZEB), meaning that the total amount of energy used by the building on an annual basis is less than or equal to the amount of renewable energy generated on site. The cutting-edge project serves as a prototype ZEB for architects, engineers, and owners to help mainstream Zero-Energy best practices.

“Our goal is to show the world that new and existing buildings can be made Zero-Energy at a cost premium of less than 15%,” said Steve Melink, who founded Melink Corporation in 1987.  “The benefits are not only significant energy savings but a reduced carbon footprint and enlightened corporate brand that attracts and retains customers and employees.”

To achieve Zero-Energy, also commonly referred to as “Net Zero,” HQ2 features several innovations, including a super-insulated envelope, super-geothermal heating/cooling system, an intelligent ventilation system, automatic lighting and shade controls, and a solar PV canopy in its parking lot with charging stations for electric vehicles (EVs).

Businesses, schools, and government agencies are invited to tour the Melink HQ2. Melink’s purpose is to educate and inspire other leaders who can further accelerate and capitalize on the shift to a clean energy economy. A grand opening celebration for HQ2 is being planned for late spring.

HQ2 is the second building on Melink’s campus. HQ1 was constructed in 2005 as a LEED Gold facility, and in the following years it was improved to Net-Zero Energy, Energy Star 99, and LEED Platinum. Also, Melink’s fleet of vehicles consists of all hybrid and EVs.

Melink Corporation is a global provider of energy efficiency and renewable energy solutions for commercial buildings with five offerings: Intelli-Hood® Kitchen Ventilation ControlsHVAC Test & BalanceSolar PV, Geothermal HVAC, and PositiV® Building Health Monitor. For more than 30 years, Melink has helped companies save energy, increase profitability, and make the world more sustainable. In 2018, Melink became an ESOP and is now 100% employee-owned.

Get A Pulse On Your Building

In today’s world, we are surrounded by smart phones, watches, cars, and other devices that are becoming further integrated into our lives. These smart sensors and technologies are helping day-to-day tasks become more efficient. To improve energy efficiency in commercial buildings and restaurants, these smart sensors and technologies can be applied in a similar manner.

Like a Fitbit that monitors and trends personal health metrics, sensors within a building can monitor and trend overall building health. With these smart sensors, important building health metrics, like relative humidity, CO2 levels, temperature, and pressure, can be measured to paint a picture of building health and HVAC performance. With data from the sensors, facility managers can identify improvements regarding building health, energy efficiency, and occupant safety and wellness within their building. PositiV, Melink’s exciting innovation in the world of building health, equips facility managers and building owners with a tool they need to verify building health and HVAC performance.

There are a variety of tell-tale signs of an unhealthy building like wet, dripping diffusers from high humidity, lower occupant cognitive ability from excessive CO2 levels, or a strong incoming draft at an open door caused by improper pressure or HVAC balance. These problematic unhealthy building signs can be addressed before becoming a costly, major issue. With building performance data, a facility manager or building owner will easier understand when building health begins to decline and identify corrective actions for the issues before they cause further problems.

A Fitbit won’t directly prevent a heart attack or make someone healthy, but it does arm its wearers with knowledge that is needed to live a healthier lifestyle. Similarly, building sensors won’t make a healthy building space, but they will equip its users with the information needed to create and sustain a healthy building space. It’s up to the manager or owner to take necessary corrective actions, but providing the data to help them make the proper decisions is the first step to improving overall building health.
