A Good Time For Technology

Posted on by Lindsey Burbee

Future of Technology

“Life moves pretty fast.  If you don’t stop and look around every once in a while, you could miss it.”  In my estimation, this quote from Ferris Bueller is more relevant now than when first uttered.  We’re in a period where everything continues to speed up. We’re moving along at breakneck speed to get to the next task, the next meeting, the next event, that it’s often easier to keep your head down.  The downside is that it’s easy to miss some of the amazing things happening in the world due to technology.

Smartphones

Smartphones, for example.  In the span of just a few years they’ve managed to become a nearly indispensable tool.  Gone are the days of proud parents stuffing their wallets with photos – you now have a literal gallery at your beck and call.  Simply carrying the phone gives us the ability to capture those special moments that in years past may be missed.  Try remembering what life was like travelling to a new city before we started carrying portable GPS units in our pockets.  What would previously take hours of planning is now done in minutes (if not seconds).  That’s not to say the consequences of ‘pocket computers’ have been beneficial, but I’d argue the good outweighs the bad by a significant margin.

Furthering Technology

Imagine opportunities to create new technology.  Instead of further connecting people (like the smartphone did), think of developing the next generation of sustainability.  Advancing business capabilities to reduce the amount of energy they consume and to make facilities healthier.  To help build intelligence that create win-win scenarios for companies and consumers at the same time.   Regardless of anyone’s beliefs on climate change and why it’s happening, it’s clear that the climate is changing.  Another thing that has been clear for some time is that the resources that we have on this planet are finite.  Finally, we’ve also learned that the cheapest energy of all is the energy that doesn’t get used.

Make an Impact

Right now, there is such an opportunity available.  Melink is actively searching for an Embedded Software Engineer and an Application Developer who would like to join our family as we continue our journey towards a brighter, more sustainable tomorrow.  We’re growing our sustainable offerings. These offerings include energy-saving demand controls for commercial kitchens (Intelli-Hood), innovative geothermal solutions (Manifest), and HVAC commissioning (Test and Balance). Melink is about to release an innovative new building health monitor (PositiV) and has more innovation on the way.  We’re also creating an awesome Portal that will connect our employees, technology, products, and customers with a clean, intuitive interface. This will create new applications to expand the reach of our hardware and improve the work-life balance of our employees.  Help us build the new tomorrow.

PACE Helps Fund Melink HQ2

Posted on by Lindsey Burbee

Word is spreading that we have started construction on one of the greenest buildings in the U.S.  Melink HQ2 will not only expand our corporate campus for future growth, it will also serve as a model for how to design and construct Zero-Energy Buildings.

What is lesser known is how this project is being financed.  Yes, traditional equity and debt will pay for 80% of this $5 million project.  There is no getting around the fact that concrete, steel, and glass costs money and plenty of it.

But the other 20% of this project will be financed by PACE – which stands for Property Accessed Clean Energy.  This is a smart way to fund energy efficiency and renewable energy improvements that might otherwise get axed from consideration because of budget constraints.

Basically, PACE financing is a long-term loan that gets paid over the long term by the energy savings of the above stated improvements.  However, rather than calling it debt, it is recognized as a property tax assessment based on the increased value of the improvements.

In this example, Melink will be able to make $1 million worth of energy efficiency and renewable energy improvements and pay for them gradually over the next 30 years through an assessment on our property taxes.  In other words, the energy savings will cash-flow the incremental value.

This is important for the building industry to understand, including developers, architects, and construction firms.  The reason is, investing up to 20% on energy improvements can make the difference between a zero-energy building and an energy hog that cripples your business.

There is no personal guarantee required and no additional debt on your balance sheet.  You get a fixed rate with fixed payments that can be passed onto your tenants through a triple-net lease.

Moreover, it allows you as the building owner and/or tenant to market your sustainability mindset and accomplishments.  And with growing pressure from customers and employees to be part of the solution, there is no excuse for not doing the right thing.

For our project, Ohio PACE and CenterBank have been indispensable partners to making this financing possible for us.  In your state, it might be someone else.  Either way, if your clients don’t know about this financing tool, you need to educate them on it.

Leading by example is one of the most important things we can do.  And with PACE financing, we hope to show countless other building owners and professionals that zero energy buildings are not only proven and practical, but also profitable.  Today.

Considerations for a Successful HVAC Equipment Upgrade Program

Posted on by Lindsey Burbee

Have you ever replaced old HVAC equipment just to find that, after spending a lot of money, the comfort issues you were experiencing previously are still there?  Or you now have new problems that weren’t there before?  Your HVAC operates as a complete system, and the new equipment is only as good as its installation quality and the existing system it is connected with.  Here are some tips to help you get the most out of your HVAC equipment upgrade program.

  1. First, be proactive.  Get ahead of HVAC issues before they get worse or before they occur at all.  The more proactive you are, the lesser the negative impacts to your facilities operating budget, revenue, customer relations, and human resources.  On the flip side, with a fix-on-fail approach, you deal with costly emergency repairs, you have high energy costs from inefficient equipment, your revenue and customer relations suffer as uncomfortable customers take their business elsewhere, and your human resources incur lost productivity and even turnover of employees due to uncomfortable/unhealthy working conditions.  Not to mention the effect on your stress level when you have to deal with HVAC breakdowns!
  2. Start with a site survey.  You need an accurate inventory of your existing HVAC equipment, so you can make decisions on what to do with it.  Be clear about what information you need to have collected from the field, information that will enable you to make a thorough evaluation and meaningful recommendations.  Examples include equipment age, condition, features, operating measures, and so on.  Remember that your HVAC is a system, made up of many components all working together.  The focus can tend to be limited to the heating/cooling equipment, but there are also other pieces of the system that are very important, such as exhaust fans, ductwork, air grilles, and controls, to name a few.  Issues with these other components could limit the effectiveness of any new heating/cooling equipment.  The system is only as good as its weakest member.
  3. Assess the data.  Review the data returned from the site surveys to assess the overall scale and scope of your upgrade program.  Determine your trigger points for repair versus replacement, such as equipment age, condition, and efficiency.  This is the methodology that will help you to objectively decide whether you will continue to invest in a piece of equipment or replace it altogether.  In grading the equipment, this could be a simple, Green – Yellow – Red system of classification.  Green meaning ‘do nothing’, the equipment is good as-is.  Yellow meaning ‘repair’, the equipment has some issues that can be corrected at relatively low cost.  Red meaning ‘replace’, the equipment has completely failed or is no longer worth investing in.
  4. Prepare a scope of work.  Apply the previously prepared methodology to your entire equipment inventory.  This then becomes your scope of work for each site.  Put the scope in writing and be clear about your expectations.  Your equipment suppliers and installation contractors will need this scope in order to provide you with accurate estimates of cost and lead time.  This advanced planning, budgeting, and coordination will help to ensure the subsequent execution of the work goes smoothly.
  5. Consider the timing.  Equipment suppliers and installation contractors tend to be busiest in the summer and early fall months when construction activity peaks.  Avoiding these times helps to ensure you have the support you need, and your costs may be lower.  Plus, upgrading before summer helps to prepare your facilities to handle the hot/humid weather ahead.  Any temporary outages of heating/cooling that may occur while equipment is being repaired or replaced is less impactful on the facility operations during times of milder weather.
  6. Vet your partners.  Working with the right people makes a world of difference.  Partner with suppliers and contractors who are trustworthy and reputable.  Make sure they have experience with your type of facility and HVAC system, and are qualified for the services to be performed.  With the right team, you can accomplish most anything.
  7. Inspect the work.  After the equipment is repaired or replaced, it is imperative that it be inspected, tested, balanced, and commissioned in order to receive the full benefit of your capital investment.  This is your final assurance that you get the quality and performance expected out of your HVAC system.  When issues are uncovered during this process, be sure to have them corrected by the suppliers and contractors while they are still under warranty.  If left unaddressed, those issues will become headaches and costs to your facilities and operations teams later.

Managing an HVAC equipment upgrade program can be a daunting job.  When it is handled in a proactive and organized fashion, and includes the right partners, the results can be extraordinary.

The 3 Most Common HVAC Problems During Winter

Posted on by Lindsey Burbee

To quote a critically acclaimed HBO television series, “winter is coming, and we know what’s coming with it.” While it may not be as bad as the army of the dead, we can expect winter to bring about a variety of HVAC issues that can cost more pennies than shivers. Here are the top three most preventable winter mishaps, and how they can be avoided with a little DIY maintenance.

  1. Frozen Pipes

Besides fire, a building’s biggest enemy is water. Only this time of year, unwelcomed water doesn’t come in the form of humidity or a leaky roof, rather, in the form of solid icy pipes. Many building owners will try to cut costs by not heating their buildings at all times while completely unaware that above ceiling and sub-floor spaces can fall below zero in extreme cold weather. These spaces are home to water pipes that can freeze and burst causing un-flushable toilets, compromised showers, inaccessible tap water, and not mention, outrageous repair costs. The residual heat from the livable spaces above or below these pipes help to keep temperatures above freezing, so setting the thermostat to at least 65 °F throughout the day and night should keep the water flowing. In addition, be particularly aware of areas that are unheated or are constantly exposed to the elements like garages, loading docks, and basement storage rooms. Insulated pipes and walls will help to seal the deal.

  1. Uneven Airflow and Temperatures

Depending on the season, air is circulated throughout a building in different ways. Cold air falls which is why in the summer months, closing floor vents to allow more air to diffuse from ceiling vents is most effective in cooling a space. The opposite is true in the winter months where rising warm air is best circulated from floor diffusers and baseboard radiators. Knowing these trivial properties about air temperature can best optimize how your building is heated or cooled, so let the cool air fall and the warm air rise!

  1. Dirty Furnace Filters

While problems that arise from dirty or clogged filters are not unique to the winter, it’s still one of the most common culprits for defective air conditioning. A unit’s air filter removes particulates from the pre-conditioned air and allows the clean air to be conditioned and distributed. If a filter is clogged, airflow is reduced, and the terminal units will have to run longer to achieve desirable space temperatures. In the colder months, the air becomes dry which can dehydrate a person’s skin as a result. With dead skin cells making up 70 to 80 percent of dust content, it’s no wonder that the winter sees some pretty dirty filters. Changing an air filter is one of the easiest, cheapest, and most effective way to ensure maximum heating outputs which is why new filters should be installed before every season.

These winter mishaps are snow laughing matter, but just like bad puns, they’re easy to spot. Keeping these three common maintenance issues in mind will allow you to brave the cold and keep cozy all winter long.

Noise! Noise! Noise! Reduce The Noise!

Posted on by Lindsey Burbee

The Holidays are upon us, with all the excitement and the parties. As the Grinch says, “And Then! Oh, the noise! Noise! Noise! Noise! There’s one thing I hate! All the NOISE! NOISE! NOISE! NOISE!”

Now, I am no Grinch about the holidays, but prior to my tenure here at Melink I worked for nearly 10 years as an Environmental Health and Safety Manager within a large chemical facility, and there were various work areas which exceeded noise thresholds requiring hearing protection. It was LOUD. This is where I became cognoscente of NIOSH (National Institute for Occupational Safety and Health) standards for hearing conservation,

NIOSH states continued exposure to noise above 85 dBA (adjusted decibels) over time will cause hearing loss. The volume (dBA) and the length of exposure to the sound will tell you how harmful the noise is. In general, the louder the noise, the less time required before hearing loss will occur. According to the NIOSH, the maximum exposure time at 85 dBA is eight hours.

Although we may not be able to control the noise of the holiday party or the loud toys the children will receive on Christmas day, perhaps within the working environments of commercial kitchens we can make drastic improvements and reduce the overall noise level.

Studies have been conducted over the years and dependent on many variables such as the size of the kitchen spaces, the duration of peak activity, and other various factors the overall noise level at times approach or exceed the 85dBA level, sources show a typical restaurant operates at 80 dB, although this value does not trigger hearing protection, some restaurants are known to reach 110 dB at times which is the noise level of a jackhammer! Think of the last time you were at your favorite restaurant and seated near the kitchen entrance versus the opposite side of the room.

Demand control kitchen ventilation can help not just provide energy savings but also reduce the noise levels drastically, especially over an 8-hour timeframe for employees in the kitchen spaces. When researching kitchen exhaust fans one will find that the noise levels are reported as a “sone” which depending on the static pressure of the design the noise levels can vary. A sone is a unit of loudness, how loud a sound is perceived. Doubling the perceived loudness doubles the sone value. Within fan specs of kitchen exhaust fans manufacturers indicate the “Sones” level for example a 5hp kitchen exhaust fan has a sone level ranging from 16.5 to 26 sones dependent on duct design. Per the decibel level and sones conversion chart this is equivalent to around 68.3 to 74.9 dB!

Now considering utilizing a temperature and optic based demand control kitchen ventilation, such as Intelli-Hood, can reduce fan speeds by 30-45% average fan speed over a 24hr period consider the reduction of noise exposure this provides. It is not uncommon for customers post installation of a Melink Intelli-Hood system to recognize significant noise reduction, many times commenting that during food prep hours, although the fans are “turned on” they operate at a minimum speed and it sounds like they are not even operating!

Perhaps you are in a position of influence of the decision to retrofit Demand Control Kitchen Ventilation, or perhaps evaluating and analyzing the opportunity for a client. Remember that there is more savings than simply energy that can be considered when evaluating demand control kitchen ventilation.

Headquarters 2.0

Posted on by Lindsey Burbee

Another major step on our sustainability journey will be the design and construction of a second headquarters in 2018 and 2019. As Melink continues to grow, we will need more office and warehouse space than our first building can provide.

Fortunately, we have the land next to our current HQ1 in which to build HQ2. It will be of a similar size and layout – with the courtyard facing our current building. And like our first building, it will be super-green. Except our second building will take green to a whole new level!

In addition to it serving our future workplace needs, it will serve as a model Zero-Energy Building (ZEB) for architects, engineers, and contractors to learn ZEB best practices. The goal will be to show a cost-benefit analysis that will make other building owners want to emulate and mainstream ZEB.

A growing segment of the building industry is calling for all new buildings to be Zero-Energy Building by the year 2030. We want to show that this can be easily achieved, 10 years ahead of schedule, with a relatively simple design strategy.

Since the largest energy loads in most commercial buildings are lighting, HVAC, and hot water, we will focus on showing how these can be minimized – and offset by a slightly greater amount of solar PV electric generation. Nothing new, except HQ2 will do this better than HQ1.

But the main innovation will be around our super-hybrid geothermal HVAC system. Don’t worry, we’ll figure out a cool brand name for it. The point is, this new system will help advance the energy savings of geothermal without the high cost normally associated with it.

If you think we have received lots of regional and national attention with HQ1, wait until you see what happens with HQ2. Through countless tours and presentations, we will influence thousands of additional building professionals and continue building a green brand unlike any company.

By the way, if any of you would like to work in this new super, high-tech, and beautiful workplace, you better get an electric car first. Because only EVs will be permitted to drive and park on its new green parking lot of the future.

The Melink Energy Revolution is just beginning…

Cultural Rules and the Global Economy

Posted on by Lindsey Burbee

Between Milford, Ohio and Barcelona, Spain we have thousands of miles for you, kilometers for me, gallons of salted water for you, liters for me, pounds of earth for you and kilograms for me…

We have different ways to talk about the same thing, but sometimes for different things we try to use the same way, what is a common mistake…

In terms of business, like the stone falling on the water, any new project will have an infinite number of concentric circles. The stone can be bigger or smaller, but always will generate a wave, big or small as well.

We will always face a person, with a better or worst day, with more or less problems, at home or at work, it doesn’t matter, with a culture, an education, inside of an organization, with a culture and an education, sometimes with people above, sometimes under, sometimes both, in a county of a region in a state of a country integrated with the economy of 28 other countries, with special regulations at different levels, different languages, different cultures…

Too complicated to be true? This is every single day of a sales in a global economy. Sometimes with more or less circles around each project, but this is the cruel reality nonetheless.

In this scenario, it becomes fully necessary having an internal decoder, armed with miles of knowledge, gallons of passion and pounds of personal skills, but also kilometers experience, liters of patients and kilograms of attitude.

How do you face this? It is easy, we build a rules structure trying include what we consider is “general” or “normal”. With these rules we don’t need to think about processes (internal or external) and we can be focused on what it is important: making a global impact.

But what happens when it is out of what we consider “normal” in our home culture, but acceptable in others? Here is when we need to show how flexible we are. It must not be a drama. This is life, different people thinking different. However, it’s important to keep the mission in mind and work towards a common good for ourselves, fellow man, and planet.

Being flexible is not meaning breaking the rules, because within these rules there are some red lines we must never cross in any culture, but we need to adapt ourselves to the situation. If we just can see the shadow of a tree is covering us, we will never be able to see the forest. We need to balance our flexibility with the opportunity cost and the risk it supposes.

So, if you know the rules, because they are yours, and within these rules exist the red lines, it is just about how flexible you are to get the job completed. And everyone has their own way, their own flexibility. There is no miraculous recipe, just training your own flexibility to convince the Polish mechanical contractor and the French end-user with different arguments to be a collective success, because they have diametrically opposed interests for the same product or solution.

To be truly global, you must be global in your thoughts and open to cultural norms wherever you may go.

Customer Experience – The Key Differentiator

Posted on by Lindsey Burbee

Good is no longer good enough! It seems it was only yesterday that every business claimed the key to winning customers was the quality of product or service they deliver. Here at Melink, we’re changing the game to focus on the customer experience! According to a Walker study, by the year 2020, customer experience will overtake price and product as the key brand differentiator. So, what is customer experience you ask? Customer experience is your customers’ perception of how the company treats them. These perceptions affect their behaviors and build memories and feelings, and may drive their loyalty. In other words, if they like you and continue to like you, they are going to do business with you and recommend you to the others. With customer experience being the new battlefield, companies are changing their approach, offerings, and business practices. Sales teams are working harder to learn their customers and their customer’s business, so they can create the “wow”. Hotel managers, restaurant chains, and even doctors’ offices are focused on creating an experience that knocks their customers socks off, instead of just standard practices.

These days, social media gives the consumer a lot of power and impact. There’s an instant feedback loop and the cluster of data starts to create the company’s reputation. For example, if you get on Amazon to buy a new bike for your son, you’re likely going to check the performance stars and the customer reviews. Any of those reviews can be the difference between you purchasing that bike and moving on to a different bike. If you’re looking for a surgeon and every website has them at 3 out of 5 stars, you’re likely going to move on to the next guy. He may be the best surgeon in the land, but his rude receptionist and office staff have poor bedside manner and make people miserable when they go in to see him. If you go to a fast-food burger joint, how likely is it that you’re going to write a positive Yelp review if you pull up to the drive thru, order your food, pay the correct amount, get the correct change and correct order, and you leave in a timely manner? Probably never! They didn’t go above and beyond and create the “wow”! If you want to improve the customer experience, there must be a “wow”! Recently I went through a drive thru myself and was caught off guard with my experience. When I pulled up it was raining. Normally I would get soaked reaching out to hand over the money. This time the cashier stuck an umbrella out the window, so I wouldn’t get drenched. Super small, super easy, but I was impressed! I’ve never seen it before in my time on this earth and he was focused on my experience! I did write a review and I tipped a drive-thru cashier for the first time!

Millennials are changing the game and companies need to embrace it. Sure, the entitlement is out of control, but the business practice changes are not all bad. If you’re focusing only on your product or service and not how your customer feels about the entire experience, you’re in trouble! Some of the large hotel companies are incentivizing their General Managers on customer experience and guest loyalty. The baby-boomers want to talk, interact, have face-to-face experiences with nice people. The millennials want to check-in swiftly to the hotel with no hiccups and have issues resolved quickly. Management needs to address all their consumer personas in a unique way to setup the individual customer experiences for success.

What happens if you fail to provide a positive customer experience? According to a recent study, 67% of customers mention bad experiences as a reason for churn and only 1 in 26 unhappy customers complain. That means companies not focused on the customer experience will lose customers well after it’s too late! Most of this is the result of what I refer to as “sales autopilot”. When you’re there trying to make it look like your product is perfect for them, without the data, you end up losing trust with them. Trust, brand and customer experience are all built on honesty. And honesty is knowing when your product won’t be a perfect fit for everyone. Therefore it’s so important to stop selling and start solving!

Since most companies will be expected to compete mainly on customer experience, organizations like Melink that focus on customer experience will stand out from the noise and win loyal customers over. One thing is for sure, if you want your customer to have an excellent customer experience and create a “wow” you must know your customers better than ever before! Here at Melink, my team and I are completing customer profiles and personas to improve individual experiences. Once you know your customers well enough, you can use that knowledge to personalize every interaction. Customers these days have more power and choice than ever before. Thus, we are responsible for understanding and acknowledging their needs. When people ask what we do, it shouldn’t be Test & Balance, Demand-Controlled Kitchen Ventilation (DCKV), Solar, or Geothermal, it should be creating the best customer experience in renewable and energy reduction markets for our customers!

Road-Tripping in a Non-Tesla 100% EV

Posted on by Lindsey Burbee

You cannot escape the responsibility of tomorrow by evading it today.

Abraham Lincoln

I have the unique pleasure of working with an employee-owned organization, Melink Corporation, that is dedicated toward making the world a better place. Our vision is to help advance clean energy such that it transforms the world through improving our global economy, security and environment – for ourselves, our children and future generations.

Though energy efficiency and renewable energy are at the core of what we do, sustainability is central to who we are. If we don’t lead by example, who will? So, in addition to operating a Net-Zero LEED® Platinum headquarters facility, we have a super-green fleet of vehicles. Our National Network of Service Technicians each drive hybrid vehicles. Our parking lot has over twenty electric-vehicle charging stations. In total we have over forty hybrids and seventeen EVs in our fleet driven. 61% of our employees drive either hybrid or electric.

I, personally, drive a 2018 Chevy Bolt and have done so for about nine months. The car has a 238 EPA estimated range and does not have the luxury of accessing Tesla’s Supercharging Network. I have a 45 mile commute, one-way from my home to my office. Fortunately, by driving an EV, living in a home and working in an office that are both powered by renewable energy, my ‘electric gas’ is very clean. I have three young kids, and it is very important to my wife and I, that we set a good example; not only so we guide them toward making their own integrity-based decisions as they mature, but also so in a direct effort preserve their future. As Abraham Lincon said, You cannot escape the responsibility of tomorrow by evading it today.

This month was the first time I took the Bolt on a good old fashion, American road-trip. I knew it would be a challenge but as another President said, nothing in the world is worth doing unless it means effort pain and difficulty. Here’s how it was (and can be) done.

The Hardware. You’ve got to have an EV that has an extended range. Here’s a list, for your reference, of the longest range EVs on the market today. But you’ve also got to have the capacity for Level 3 charging. On the Chevy Bolt the hardware cost an incremental $750, from the factory. GM advertises 90 miles of charge in 30 minutes, up to the 80% mark and the speed begins to taper to protect the battery.

The Fuel. There are of course Plug-in Hybrid EVs such as the Chevy Volt and Honda Clarity. Those models have about 30 – 50 miles of battery capacity with traditional gasoline as a backup. This isn’t the kind of EV I’m talking about here; I’m talking about 100% electrons. And I must acknowledge that during my road trip the electrons pulled from the grid may be coming from brown-power sources; but not necessarily. Wal-Mart, for example, has solar on many of their locations. And one of the two EVgo stations I charged at was at a Wal-Mart. Nonetheless, what’s the advantage of driving an EV vs. a traditional internal-combustion engine that uses gasoline? For one, EVs convert about 60% of their energy from the grid to power at the wheels; gasoline only converts about 19% of the energy stored to the wheels. Also, electricity, even from a coal-fired power plant, is a domestic energy source. Finally, you can get your electricity from renewable sources such as solar and wind.

The Apps. Before making any long-distance road trip, pre-planning the locations of charging stations (and their distances from one another), is critical. There are a number of apps you can use to see what’s out there: PlugShare, ChargePoint, and EVgo are the ones I use.

The Infrastructure. EVgo is America’s largest Public Electric Vehicle Fast Charging Network, with over 1,000 chargers in 66 markets. As a non-Tesla driver, this network is vitally important for the emerging EV market.

The Planning. A few days before my trip from Southwest Ohio to Eastern Tennessee, a 350 mile commute, I identified two Level 3 Fast charging stations and one Level 2 charging station for my trip. The first Level 3 charger I stopped at was only 35 miles from my house, located at a Wal-Mart in Florence, Kentucky. I topped off and drove another 239 miles to Knoxville, Tennessee… quite literally almost no margin for error between charging stations. Fortunately, during my planning I learned of an EVgo charging station that’s being installed about 3/4 that distance, along I-75 near Williamsburg, Kentucky. So the infrastructure is continuing to develop. After making it to the next fast-charger in Knoxville… I had 8 miles to spare. Nonetheless, I made it. So I charged for about one hour (180 miles). While I waited I was able to eat lunch and catch-up on some work. Then I drove another 35 miles to my final destination, which was for business purposes There I stayed for about 30 hours, plugged in to a residential 120V outlet at 12 amps. I got my charge up to about 90% before making the return trip… back to Knoxville, then to Florence, then home. Similar to my first-leg, I made it back to the Florence charger with about 6 miles to spare.

Lessons Learned. For one, my tire pressure was relatively low when I left my house. It took the necessity of my thin battery margin to realize the impact it had on my mileage efficiency. So, I filled them almost to max-pressure and the Bolt was ‘intelligent’ enough to roll this new information into its algorithm, thus giving me an increased range by about 10 miles from where I was before. Second, I noticed that by turning off my air conditioning, the algorithm gave me another 10 mile boost in my range. Also, I tried to keep my speed (on I-75, no less) at around 65 mph. You’ll notice in this chart the relationship between speed and range; the faster you drive, the less efficient your mileage.

In order to change the world, we’ve got to do things differently. Otherwise, if we continue to do the same things, nothing will change. This trip wasn’t easy. An otherwise normal five-hour trip took me about seven-hours, one way. I didn’t want to leave the house at 5am and I certainly didn’t want to get home at 2am. But I wanted to demonstrate it could be done, in the hope that just maybe it inspires others to make the leap, not only to an EV, but to a brighter future.

Top 5 Negative Building Pressure Problems

Posted on by Lindsey Burbee

The difference between outside air supplied to a building and air removed from inside a building is the building pressure.  Typically, a slightly positive (or more air being supplied than taken out) building pressure is wanted for most buildings.  Negative building pressure can cause many issues for customers from high energy costs to hot and cold spots in a building.  Here are the top five problems a building with negative pressure can experience:

  1. Difficulty Opening and Closing Doors:

One of the first signs that a building is negatively pressurized, is when the front door is not easily opened.  After finally opening the door to a negatively pressurized building, a large draft will be felt on your back as the door is slammed closed.  Because buildings are typically designed to be positively pressurized, you should feel a soft gust of air blowing outward when this is set properly.

  1. High Humidity:

If your building is negatively pressurized, the building will pull in unconditioned outside air through all openings including doors, windows, and other leaks in the structure. This is very noticeable in the summertime when outside humidity is especially high.  This can cause mold or mildew in the building.

  1. High Energy Costs:

Studies have shown that correcting negative building pressure can save a facility owner as much as 20% on their HVAC energy costs.  By ensuring your facility has a positive building pressure, you are avoiding unnecessary costs and maximizing comfort in the facility.

  1. Outside Debris:

In a facility that is negatively pressurized, owners are more likely to see outside debris being pulled into the facility through various openings. These items include, leaves, flies, dirt, as well as smells brought in from outside.  In many facilities, this could create major issues with production as the outside debris could be contaminating the products.

  1. Hot and Cold Spots:

Another symptom commonly noticed in buildings with negative building pressure is noticeable hot and cold spots that are created by the disrupted airflow.  This could cause the customers to become angry because they can’t reach a comfortable temperature in the building.  In a restaurant, this could also cause food at the counter to become cold.
