Economic Recovery and the Clean Energy Revolution

Recovery, Growth, and Clean Energy

Companies, non-profits, government organizations, healthcare facilities, and institutions of higher learning will soon look beyond survival to recovery, and eventually growth. It is a rising movement called the Clean Energy Revolution. It may be difficult to visualize this given our current state of affairs, but this too shall pass, and better times will come. Our culture has seemingly lost its ability to think and plan for the long-term; priorities, politics, and results are driven by short-term metrics. As such, I believe that we should use this opportunity to reinvent, rethink, and rebuild with the following attributes in mind: organizational resiliency, serving the common good, equability, and sustainability.

Sure, this all sounds great. But what do you mean?

I tend to think of nearly every problem (opportunity) in terms of the Pareto Principle, better known as The 80/20 Rule. It asserts that 80% of outcomes result from 20% of all causes for any given event. In business, for example, the goal is to identify what actions or inputs are most productive and prioritize them accordingly.

The Pareto Principle or the 80/20 Rule

So, as it pertains to this concept, I believe there are two inputs we should focus on with respect to economic recovery, arguably the biggest global challenges of our time (COVID-19 + climate change), and the attributes I mentioned earlier (Resiliency, serving the common good, equability, and sustainability). Speaking broadly, they are 1.) Energy and 2.) Health.

No, seriously. I get it. Give me specifics.

OK, first we need to deal with the public health crisis at hand. Social distancing, wearing masks, and limiting travel — these practices are already in play and are driven by behavior. But the one thing we can do to make people feel more comfortable returning to our prior norms, such as returning to work, shopping, eating at restaurants, etc. is to invest in the health of our buildings. By focusing on healthy buildings (HBs), we will not only make people feel comfortable, but help reduce the spread of the virus and make ourselves more productive. This leaves our employees, customers, and any other stakeholders feeling better and more productive.

So, what constitutes a healthy building?

Sick building showing indoor air quality

First, seek to understand sick building syndrome (SBS) and building related illnesses (BRI). The EPA defines SBS as a situation in which occupants experience acute health and comfort effects linked to time spent in a building, but no specific illness or cause can be identified. Indicators of discomfort include headaches; irritated eye, nose, or throat; coughing, dry or itchy skin, nausea, and difficulty concentrating among other symptoms. Occupants report relief soon after leaving the building. Physical evidence within the building itself includes an incoming draft at the front door; hot or cold spots throughout the facility; condensation on ceiling diffusers; slippery floors; mold; hard to open doors, high energy expenses, and other contributing factors. BRI is indicated by occupants reporting of symptoms such as cough; chest tightness; fever, chills; and muscle aches. These can be clinically defined and require some recovery, after leaving the building.

Holy cow. I hadn’t thought of all this being related to buildings. What are the primary causes of SBS and BRI?

Poor HVAC performance such as inadequate ventilation and negative building pressure.

OK so, how can I invest to make my building healthy as you suggest?

This is a loaded question. There are A LOT of things you can do. I’ll try to keep this brief.

First and foremost, make sure the HVAC system has been well maintained. And think about the health issues described above. Are these currently problems? If not, you may not need to do much, though there’s certainly always room for improvement. If these are problems, consider consulting with an expert on HVAC and healthy buildings. Make sure they’re independent of whomever is responsible for your maintenance and certified to do so. They’ll likely perform an investigation and assessment on the HVAC system, as well as indoor air quality. The factors to be evaluated (and adjusted) on the HVAC system include but aren’t limited to verifying equipment operation; checking building pressure; inspecting filters, belts, and fans; and finally asking questions about comfort. The primary factors that influence indoor air quality are the occupants; the HVAC system; pollutants and their pathways; and internal and external contaminants such as chemicals, smoke, grease, molds, and pollen.

Energy Revolution

After these initial assessments are complete and adjustments made, get some form of system to monitor building health. Think of these monitors like having a FitBit for your building; empower yourself with data to maintain proper health. There are plenty of options out there and what you install should monitor some of the following attributes: differential building pressure (the #1 indicator of overall building health); C02; relative humidity; and temperature. Monitoring these core attributes will cover the 80/20. Other important, albeit less impactful, attributes to monitor may include volatile organic compounds, water quality, noise pollution, occupancy, lighting quality, and energy usage.

Building health alone covers more ground than I imagined. But you also mentioned energy. What can I do there?

Invest in Energy Efficiency (EE), Renewable Energy (RE), and Clean Energy Transportation (electric vehicles or EVs). The Clean Energy Revolution is way more than just building health alone.

 

Why? And, how does this relate to helping with economic recovery?

There are a number of reasons. Quite honestly, too many to cover without writing a book. So, again, I’ll focus on the 80/20.

Economic Opportunity

First, and most pressing is economic opportunity. Energy, and the cost of it, flows through everything. Think about that. The cost. of. energy. flows. through. everything. As far as EE goes, the cost of energy saved is the lowest cost of energy. This is a no-brainer with a guaranteed ROI. Further, the cost of RE is at or below the cost of traditional fossil-fuel based sources, depending on the state, scale, and application. And EE, RE, and EVs are driven by technology — not sources of fuel. In terms of economic growth, every measure of kWh or BTU saved by EE or generated domestically by RE translates into wealth we are not exporting to foreign nations. Put that into perspective, relative to the cost of energy, which is buried in the cost of everything.

Moral Imperative

Making the transition is a moral imperative during the Clean Energy Revolution. The science is clear and indisputable. We are harming our earth. If we do not reverse course, soon, the damage will be irrecoverable. Remember how quickly COVID-19 swept the globe and how we’re still reeling from its devastating impacts. Climate change is a crisis in slow motion. Yet, unlike this virus and the subsequent public health crisis, the impact will change the face of the earth — and humanity —forever. I cannot, in good conscience, put that burden on my children and grandchildren. We have borrowed at their expense for far too long.

National Security

Making the transition is a matter of national security. How many global conflicts have been fought over the allocation of natural resources? This strategy not only protects the lives of future generations through preserving the earth but, quite literally, may prevent them from fighting avoidable wars. When we leverage technology for our energy, we are not subject to the whims of foreign nations and their strategic interests. As the world seems increasingly less stable, this also seems like a no-brainer, let alone the cost savings relative to current military spending. Simply put, an investment in clean energy is an investment in our own national security.

Shaping Our Future

Finally, consider how past industrial revolutions have shaped our nation. The emergence of water, steam, and coal as sources of power and how they expanded industries such as railroads, steel manufacturing, electric lighting, automotive, and the digital revolution — which brought forth widespread globalization, low-cost economies, and new business models. What is next? I pronounce we are in the beginning of the Clean Energy Revolution. And once we have hindsight, I truly believe it will surpass prior examples in terms of how it changes the world. Do we want to be the leaders of this revolution? Or will we continue to cede this opportunity for other nations to embrace? If we do not lead this New Age, what’s next for America? Let’s dismiss coal and oil to embrace the future. The potential for job growth and opportunities for continued innovation are beyond comprehension.

Clean Energy

It is clear that investing in the Clean Energy Revolution will make our nation more resilient, equitable, sustainable, and resilient. Much like other successful businesses, we won’t rebuild our economy by relying on fossil fuels. We cannot subsidize our way out of this. So, let’s learn from our current crisis as we begin planning for a better future. None of us can carry the world on our shoulders. But we can carry our world on our shoulders. If we do our part individually, collectively we can make America — let alone the world — a better place if not for ourselves, then for future generations.

HVAC Ductwork Design

 HVAC Ductwork Design

Have you ever wondered how HVAC ductwork is designed?

There are six methods for designing low, medium, and high-pressure HVAC systems:

  • Equal Friction Method
  • Static Regain Method
  • T-Method
  • Extended Plenum Method
  • Velocity Reduction Method
  • Constant Velocity Method

The most commonly used method is the Equal Friction Method. This method is used for low-pressure systems found in commercial buildings. It’s distinguishable by pressure loss per every 100 ft. of duct and is designed to be the same for the entire system. A well-designed system has an average friction rate of about 0.1” of water column per 100 ft. of duct length.

After determining the desired friction rate and CFM (cubic feet per minute) of airflow for a system, an air duct calculator properly sizes the ductwork that can support these requirements. The disadvantage of the Equal Friction Method is the lack of provision for equalizing pressure drops in duct branches. This only works if the duct layout is symmetrical.

Air Duct calculator for HVAC ductwork design

Why Is Duct Design Important?

HVAC systems are comparable to cardiovascular systems. Rooftop or air handling units are the heart, and the HVAC ductwork design is the body’s arteries and veins. Continuing this example, if arteries or veins are too big or too small, issues (such as high blood pressure or a stroke) can arise.

Comparatively, if ductwork is incorrectly sized, vital issues to the units can arise. Having ductwork that is too large can lead to a low CFM (Cubic Feet per Minute) of air flow in a given space. This can cause the unit to run longer in attempt to heat or cool a space. Inversely, having too small of ductwork can lead to high velocities and static pressures. This can create a loud environment and put unnecessary stress on the system.

In conclusion, incorrectly sized ductwork negatively impacts a system’s lifespan and energy expenses. Properly sized ductwork leads to lower energy expenses, longer unit lifespans, and more comfortable environments.

How Does a Melink Technician Verify Ductwork Installation?

While on site performing a Test & Balance, Melink technicians assess if duct systems are installed correctly. They analyze the duct system in the situation where proper airflow is unattainable. Unless unit total speeds are further adjusted to deviate from the design and rectify the imbalance.

As a result, Melink technicians reference mechanical plans, duct design tables, or an air duct calculator to verify proper duct size. Afterwards, they reference this to the given amount of air flow, then compare it with the installed ductwork.

This picture represents how air moves in ducts. Red areas have high static pressure, and green areas show high velocity.

Trained technicians inspect and identify dynamic losses areas, portions of ductwork with high friction rates and static pressure.

Dynamic loss examples due to installation errors are incorrect duct take offs, failure to include duct turning vanes, long runs of flex duct, or crimped flex duct. These issues can shorten the unit’s lifespan if not corrected. For instance, these issues can average costs of $1,200 per year extra in energy expenses.

Lastly, duct design discrepancies found during a TAB are reported and photographed for the customer’s reference.

The Electric Revolution

Are electric vehicles (and electric options of all kinds) the future?

The year is 2008. The best-selling vehicle in the United States for the 27th year in a row is the Ford F-Series truck with more than 500,000 sold.

Fast forward to 2020. We are entering a new phase in the automotive industry. As of February, Tesla passed a significant milestone, selling 1 million electric vehicles (EV). Plus, the Tesla Model 3 became the all-time best selling EV globally. This happened in just 2.5 years of production, which had taken the previous leader almost 10 years to accomplish.

Clearly, this is a very exciting time for EV enthusiasts as options become more stylish, have longer ranges, and achieve faster 0-60 MPH times, all while becoming more affordable for the average American. In fact, this is an exciting time for electric options of all kinds…

Is Everything Going Electric?

You may not realize it, but electric operation has been utilized for many years. No matter what your indoor or outdoor “go-to” is for fun or home improvement, chances are that an electric powered vehicle or tool has helped you get the job done.  

Have you ever been golfing and paid for “18 and a cart”?  If it has been in the last 15 years, it was probably an electric golf cart. More into walking the golf course? They make “smart cart” bag carriers that can now follow you based off of remote control or a “follow me” clip attached to your belt.

If golf is not your sport, how about skateboarding? Hop on one of a myriad of manufacturers’ longboard, traditional, or one-wheel style boards to rip the streets or trails with speeds of 60+ MPH, or a range of almost 60 miles.

Maybe being outdoors isn’t your thing, but you like having a tidy, well-groomed yard… Look no further than Husqvarna or Worx for their cordless, robotic lawn mowers, controlled by an app and GPS.

Electric History
All these EVs, toys and tools sound great, but what happens when they run out of charge?  Well, the history of the battery — the backbone of electric powered tools and toys — is longer than you may think. The first recorded battery to provide continuous electrical current to a circuit was created by an Italian physicist, Alessandro Volta, in 1799. This was very crude, using zinc and copper for the electrodes and a piece of brine-soaked paper for the electrolyte. We have since gone through Daniell Cell (1836), Lead-Acid (1859), Nickel Cadmium (1899), Alkaline (1950s), Nickel-Metal Hydride (1989), and finally Lithium-Ion (1991) batteries. (Read more about “The Evolution of Battery Technology.”)  

Or maybe you work in a warehouse and are sick of the noise and smell of gas-powered fork trucks. Well, you guessed it — there is an electric battery powered alternative. 

And kids from 5 to 15 years are getting more and more into hoverboards; electric scooters; electric RC cars, planes and boats; Power Wheels, and even dirt bikes. In fact, I see this trend in my own home. My kids have hoverboards and love them, but they are already looking to the next electric transportation method of their dreams: the one-wheel, a scooter, a dirt bike, etc.  I can no longer tell them that such “toys” will disturb the neighbors because the days of the iconic sound of a two-stroke or four-stroke dirt bike may soon be over with how quiet electric motors have become.

Benefits of Electric Vehicles

Now, this movement toward electric transportation (and more!) does not have to be all about fun.  Some people choose electric it for the savings or the impact on climate change.

Let’s just focus strictly on EVs… Most consumers can expect to save $600-1,300 a year in fuel costs alone when switching from a conventional vehicle. Now, factor in less required maintenance like oil changes and brake service, and the savings just keep stacking up. It can take as little as $0.12/kWh to charge your car, meaning a full “tank” can cost as little as $5 or $6. How does that compare to your last fill up?

Other consumers may switch for the wellbeing of our environment and our children by aiding in the removal of toxic emissions. In 2008, the U.S. averaged 55,108,100 gallons of gasoline sold per day. That is an annual total sale of 20,114,456,500 gallons. This led the U.S. to 5,817 million metric tons of CO2 emissions.

However, since the introduction of EVs, this consumption trend has declined. In 2019, the U.S. averaged just 24,239,300 gallons of gasoline sold per day. This makes for a 30,868,800 gallon per day difference, for an annual consumption difference of 11,267,112,000 gallons! That is an average reduction of 1,024,282,909 gallons per year.

If the EV trend sticks and its popularity continues to rise, the U.S. will consume 12,291,394,909 fewer gallons of gasoline in 2020 than just 12 years prior.  At a current national average of $2.186, that means that as a nation, we will save an estimated $26,868,989,271.07 on gasoline purchases this year. That is enough money to purchase any of the following:

  • 2 U.S. Navy Nimitz Class Aircraft Carriers
  • 15 Buckingham Palaces
  • 16 Burj Khalifa towers
  • 50,000 Teachers hired for 10 years
  • 597,088 Tesla Model 3 cars
  • 700,000 Homes powered with solar energy
  • 3,400,000 People fed three meals a day for a year

Our Electric Future

So, whether you are into electric power vehicles and tools for personal enjoyment or trying to do your part for a cleaner Earth, there is an electric, battery powered solution out there for you.  So, get out there and form your own opinions on all things electric.

I challenge you to go electric and just see how you like it! Get behind the wheel of an EV, or climb onto an electric dirt bike and try not to have fun! The torque, the acceleration, and the handling — all of it is intoxicating. It pulls you in and makes you want to find reasons to drive the car or ride the dirt bike at every opportunity.

So drive a Tesla, do a handyman job using a 20v Li-Ion powered tool, rip the local trails on a Onewheel, film a YouTube video using a drone, go golfing and ride along in an electric cart, or start a new hobby with your kids with brushless electric motor RC vehicles. There are so many emerging trends within the battery powered world, and electric vehicles are just one of them.

Will the world ever regress, ever think about going back to its fossil fuel roots? Perhaps so, perhaps not.  As for this new EV owner, I’m never looking back.
