Sustaining A Great Place To Work

Posted on by Lindsey Burbee

During almost every interview or conversation I have with a non-Melinker, I am asked why I love Melink. My response is always the same, the employees!I am grateful for the “Good Mornings” as employees pass my office, to hear Lorie’s laughter, the conversations at the coffee pot, and sharing thoughts and ideas with my teams.  If you know Melink, you know that we are a leader in energy-efficiency and sustainability practices, but our biggest asset and greatest advantage is our employees.

Every year, one of our top strategic objectives is to ensure our organization is considered a Great Place to Work.  I am proud to say that for the last 2 years we have accomplished that goal! It’s very gratifying to know that 93% of our employees told the institute they feel management is honest and ethical in its business practices. What’s more, 96% indicated they have great pride in who we are and what we do!

So, how do we sustain and keep that momentum?

We have to be transparent about our goals and actions, and very intentional about making sure we are meeting the needs of our employees and providing a satisfying work life, which can certainly be tricky with half of our employees being remotely located across the world. That is why I love Springtime at Melink as we approach our Annual Company Meeting.  This is our own version of a big Family Reunion! We get the chance to be together in one and ensure all voices are heard. All employees gather at our headquarters in Milford, Ohio to reconnect (or meet for the first time!), catch up, and learn more about each other.  We share thoughts, conduct training, share our hopes and concerns for the coming year, and of course have fun!  We will beat up new processes, challenge each other to meet our customer needs, and focus on delivering the best results to achieve our annual and strategic goals. It is an all-hands-on-deck, no holding anything back type of week!

Our 2018 meeting is right around the corner and the planning is almost finished. Food has been ordered, hotels confirmed, flights are scheduled, and agendas finalized. Our remote employees will start to arrive tomorrow. Our days may be packed with educational sessions, brainstorming meetings, internal presentations, and forecasting, but we have plenty of fun planned too!  This year we are excited to have Scott Tallman share his BBQing talents for a cookout, and enjoy a dinner cruise down the Ohio River (thanks Lorie!).

The energy is building and we will soon conduct our survey again. How did we measure up? How do we impact our employees? How do we continue to keep them engaged? While I have a good pulse on where we stand, I can’t wait to show the world once again how Melink stacks up as a Great Place To Work!

A Letter To Employees From Steve Melink Regarding The Paris Climate Agreement

Posted on by Lindsey Burbee

Hi Everyone,

I am sure you heard that President Trump withdrew the U.S. from the Paris Climate Accord, and some of you may be wondering what the impact will be for Melink and other like-minded leaders in the clean energy age. The answer is none. No impact, zero, zilch, nada!

Our commitment is unequivocal. We are not less steadfast – we are more steadfast in the face of bad politics and fake news. We have to be because our U.S. and global economy, security, health, and environment depend on it. Climate change, in particular, is a growing risk and threat that we must fight today and not after it becomes too late. Our children and future generations will see this as our ultimate legacy.

The Paris Climate Agreement was signed by almost 200 countries. It is supported by many of the largest and most successful companies in the U.S., including Apple, Google, Facebook, Microsoft, GE, P&G, Bank of America, Walt Disney, Pacific gas & Electric, Salesforce, 3M, Citigroup, Corning, Coca-Cola, Goldman Sachs, Dow Chemical, Johnson & Jonson, Morgan Stanley, Tesla, Unilever, and many others.

This is not about jobs in Pittsburgh verses Paris. This is infinitely larger. And hence we will continue our good work to ensure we end up on the right side of history. Science and data will lead us, not rhetoric and short-term thinking.

We are just a medium-sized company, but our leadership and influence are critical in our state, industry, and the local communities in which we live. Thanks for living our mission and sharing this journey with me.

Back to work …

Purchasing an Electric Car

Posted on by Lindsey Burbee

You may have noticed by my title – I’m senior accountant at Melink-  that I’m involved with finances. It’s in my nature to look for a good return on the money I invest in products and services. So, when I decided it was time to purchase my first electric vehicle (EV), I conducted a good amount of research.

I decided on a used 2013 Chevy Volt, and it has been everything I hoped. Being diligent in charging my Volt – at home and at work – I was even able to drive 3,000 miles on one tank of gasoline.

 

When considering an EV, the most important thing to determine is your realistic commute. That will help you weigh the pros and cons of the limitations of a pure electric car. Starting with a zero-charged battery, an EV (pure electric and gas backup models) will take anywhere from four to 22 hours to fully charge for a 40-200 mile range depending on the model and charger you select. Take it from me, invest in a 240V charger if you want the shortest charge time.

In the United States, there are about 20 models of mainstream EVs available for purchase.

A Balancing Act: Air Balance is an important part of HVAC maintenance

Posted on by Lindsey Burbee

When it comes to HVAC, no news is good news for restaurant facility managers. When you start hearing chatter about the building being hot and humid, drafty, smoky or uncomfortable, you know a problem has already taken root. It’s like a piano being out of tune. In addition to unhappy customers and employees, comfort issues are indicators of energy inefficiency within a system and air balance issues. So, what can facility managers do to prevent comfort and energy threats?

Identifying Common Problems

“Facility managers need to be trained on air balance and push it to their service contractors,” recommends Jeff Dover, resource manager at RFMA.

A good place to start is to gain a foundational understanding of building pressure and common HVAC deficiencies along with following seven easy steps to bring your restaurant back into tune. Most importantly, learn how to look for negative building pressure. Remember, the goal is to stay slightly positive in building pressure.

There are three methods to identify negative building pressure. The first and most reactive method is to monitor signals that your building is negative. These signs are hot/cold spots, entry doors that are hard to open, poor smoke capture, humidity, condensation dripping from diffusers and drafts.
Second, you can measure the building pressure yourself or with the help of your service contractor by using a pressure reading tool such as an anemometer to get a ballpark pressure reading. The third and most accurate method is to hire an air balance firm to check the facility’s building balance once a year. If comfort-related issues or a negative building pressure reading are observed, then an air balance needs to be scheduled.

Investigating the Cause

What causes a building to become negative or unbalanced? The usual offenders are equipment deficiencies, improper preventative maintenance programs, and adjustment errors such as kitchen staff fiddling with thermostats or service contractors opening or closing dampers.

 Here are 10 example deficiencies you or your service contractors should be on the lookout for:
  1. Exhaust fans in poor condition
  1. Supply air leaking above ceiling
  1. OA dampers improperly installed
  1. Exhaust fans not sealed to curb or hinged correctly
  1. Dirty compartment/coil in the RTU
  1. Tops of diffuser not insulated
  1. Filters improperly sized for hoods
  1. MUA not operating properly
  1. Dirty indoor/outdoor filters
  1. Worn/broken belts

Achieving Air Balance in HVAC

Once you’re ready to bring a facility back into tune, there are seven easy steps to complete. These steps may be completed by the facility manager alone, but are more likely in partnership with a service contractor. To get started, pull out the facility’s previous balance report to use as a base line for data.

One Principal Engineer at a hamburger fast food chain overseeing thousands of locations explains how her team uses the air balance report to get started with troubleshooting comfort issues.

“The reports really are my first line of defense when someone says ‘Hey, my store is cold/hot/humid,’ she points out. “The first thing I do is pull out the TAB report and see what it says. I look at the punch list and ask was anything wrong? Not fixed? It helps when I have to remotely assess or diagnose problems.”

7 Steps to HVAC Balance

Whether the previous air balance report has been reviewed or not, proceed to the following steps:

  1. Ask the onsite restaurant managers what the complaints are from employees and customers.
  1. Turn on all HVAC equipment.
    • Verify thermostats are set to “FAN ON”
  1. Check building pressure with the flame test in different areas around the restaurant (Figure 3)
  1. Observe smoke capture
    • Is the hood in the correct overhang position?
    • Are there drafts along the cook line?
  1. Check for common comfort issues (hot/cold spots, entry doors that are hard to open, poor smoke capture, humidity, condensation dripping from diffusers and drafts).
  1. Inspect the equipment.
    • Are the filters clean?
    • Are the belts in good condition?
    • Are the exhaust fan wheels clean?
  1. Determine an intervention plan.
    • If some preventative maintenance actions and/or repairs need to happen, start with the service contractor.
    • If equipment is inoperable, have it repaired or replaced.
    1. If the preventative maintenance actions are in order and the problems persist, call in a certified air balance company that has experience with restaurants like yours.
Facility managers need to trust that their service contractors will notify them of airflow-related issues. Those technicians are out on the roofs and looking at the HVAC system components more than anyone else. If the restaurant has negative pressure or other out-of-tune symptoms, the service contractor needs to inform the facility manager right away. After all, you want your customers and employees to continue singing your praises.

Air Balance Basics for Existing Facilities

Posted on by Lindsey Burbee

We understand the concept of the “band-aid approach” whereby you find a quick cover-up to a problem without actually investigating the root of the it.  This concept applies frequently to Facility Managers or Building Owners wrestling with HVAC emergencies being caused by negative building pressure. They tackle issues such as condensation, hot/cold spots, humidity, odor, and difficult to open doors with “band-aids”. These “band-aids” are in the form of increased air conditioning, dehumidifiers, wet floor caution signs, door mechanisms, air fresheners, apologizing to patrons, comping customers’ bills, and so on.  This is understandable when you’re managing 80+ facilities, all with problems that stretch far beyond just HVAC.  However, it comes with a cost of spending a lot of time, money, energy, and reputation just to have the issues continuing to come back.  While balanced airflow is not a tangible product, the consequences of an unbalanced building are very perceptible.

Facility Managers are ready to de-mystify their HVAC issues by understanding the root causes. Use the air balance basics below to recognize when an issue is airflow related.

 

What does it mean to have a balanced airflow?

Think of financial statements with income listed in one column and expenses in the other.  Much like a budget, you want incoming cash coming to be equal to or greater than cash going out. You typically want the air going into a building to be slightly greater than the air going out.  Similarly, think of a balanced scale.  In the graphic below, air is being drawn out of the building by exhaust fans at a rate of 4000 CFM (cubic feet per minute). This is to remove heat and smoke from kitchen cooking appliances and foul air from the restrooms. Air is also being introduced into the building through an outside air fan, at a rate of 4500 CFM. This is to provide fresh breathing air for the occupants and to replace the exhausted air.  The result is a slightly positive building pressure of 500 CFM (4500 – 4000 = 500), which signifies a balanced airflow.  Conversely, if air coming into the building is slightly less than the air leaving the building, then you have a negative building pressure, which is the frequent culprit of many HVAC problems.

Which brings us to a crucial pairing to the air balance concept.  That is if balanced airflow is peanut butter, then a performance test is the jelly.

 

What is an air test & balance service? 

Air balance testing is the process of measuring HVAC airflow performance.  Once tested, the systems are then adjusted, or balanced, so the air brought into a building is slightly greater than the air being pulled out of the building.  The benefit for testing and balancing being a combined service is explained by Rob Falke, President of the National Comfort Institute, “This [positive] pressure condition can be designed, but to be sure it actually happens requires air diagnostic testing.  However, it’s hard to say how great the positive pressure reading in the building will be. It depends on how tight (or leaky) the envelope of the building is, and what other pressure generating forces exist, including the wind, appliances, exhaust fans, and the stack effect of the building.”  The result is a comfortable, healthy indoor environment with an HVAC system that is optimized to perform efficiently.

3 Steps to Troubleshooting Your Facility’s HVAC With Onsite Staff

Posted on by Lindsey Burbee

HVAC Troubleshooting

Have you identified that your facility is experiencing a potential air balance problem?  You might be experiencing hard to open doors, uncomfortable temperatures, poor smoke capture, odors, drafty areas, or any combination of the other common sick building symptoms.  The inevitable question now is, “Who can resolve this best?” Bringing in your facility’s mechanical contractor may be your first instinct but troubleshooting with your onsite managers is actually the best place to start. Work through the following questions with your facility’s day-to-day manager:  

1.  Is the equipment running?

As basic as this may come across, it is absolutely crucial to check if all HVAC equipment is operating. Check grilles to see if air is being blown out or sucked in. Check roof equipment, can you hear the fans from the RTU, MUA, or EF units spinning? Have the manager record and communicate findings.

2. Check the Thermostats

Navigate to the wall mounted thermostats and ensure they have the proper set points. Often, a thermostat is installed and connected to the system and then left alone. When this occurs the thermostat is left at factory settings which is often set at a random temperature. Your staff can follow the directions on this thermostat to program it for the desired temperatures.  As well, check the thermostats for “Fan ON.”

3.  Check the Circuit Breakers

Check indoor and outdoor circuit breakers. Observe tripped or “Off” breakers. DO NOT flip the breaker on. If tripped or left off, there’s likely a reason for it and you don’t want to risk frying the electrical systems. We recommend calling an electrician for this type of deficiency.

 

Armed with your findings from these simple tests, you can save some money with a Do-It-Yourself fix.  It’s possible that the journey back to a healthy building ends here.  But if the problem persists, it’s time for the level of technical know-how. Call the mechanical contractor. With your observations to these preliminary steps above, you can approach your mechanical contractor with information that will help them to better understand your situation and get you closer to achieving a healthy building.
