A Renewed Focus on Energy Efficiency – Energy Audits

By: Julie Lundin, LEED AP ID+C, WELL AP

2020 is in our rearview mirror.  The pandemic will end, most likely sometime in late 2021.  Businesses are beginning to restart and plan.  However, much has changed since the pandemic took hold of our lives and economy.  Initially the commercial building industry’s focus has been on the health issues of building occupants by addressing IAQ, employee density, social distancing, occupancy patterns and work schedules. But an important aspect not to be overlooked is to refocus on proactive strategies that manage operating expenses. With increased vacancy in commercial properties, decreased economic and business activity, now is the time to institute energy conservation and cost-saving measures to help contain building operating costs. A commercial energy audit will help building owners become more profitable by reducing wasted energy use whether operating under normal business conditions or COVID-19.

Commercial Energy Audits

What comes to mind when the term “audit” is used?  I usually think of a financial audit which requires a close examination of documents and perhaps a negative outcome.  The term “energy audit” might initially invoke the same response from building owners and managers. The idea of closely examining a buildings energy needs and operating efficiency might appear to be looking for unwanted change especially if the building seemingly operates fine daily. A commercial energy audit should be viewed as an energy opportunity assessment to reduce energy expenses and increase profit. Compared to a financial audit when the best that could happen is nothing, an energy audit has positive outcomes.

What motivates an energy audit?

With the inherent push back on change what motivates building owners or CFO’s to conduct an energy audit? It is usually financial driven, sustainability driven or a combination of both.  An energy audit is often the first step in making a commercial building more efficient.  The goal of an energy audit is of course to identify energy-saving opportunities but can also increase asset values, lower ownership costs, and promote environmental stewardship, human comfort, health, and safety.

What is involved in an energy audit?

Buildings, whether long-standing or recently constructed, have potential for energy improvements.  Typically, an energy audit is a loose term and follows a general framework of identifying energy usage throughout the building, assessing building systems, and conducting on- site inspections. A final report is produced outlining energy conservation and system improvement measures.

However, an energy audit is a specific term defined by ASHRAE, a global organization focused on advancing technology to improve sustainability. ASHRAE specifies three types of energy audits:

  • Level 1: A basic, high-level walkthrough. It requires data collection regarding the operation of building systems and a review of facility utility bills with the purpose of identifying major problem areas.
  • Level 2: Includes a Level 1 audit and additional complex, detailed calculations in connection with proposed energy efficiency measures.  Note: The literature suggests an entire workbook of calculations for each identified project, which means people tend not to identify small projects because the write-up is the same. As a result, a Level 2 may less useful because organizations do not consider ways to address the “low-hanging fruit” (such as LED lighting, for example) which tend to have low-cost and high return—avenues for energy efficiency that are certainly worthy of consideration.
  • Level 3: Sometimes called a “comprehensive audit,” this level includes more detailed data analysis related to the projects identified during the Level 2 audit, as well as extensive cost and savings calculations.

The result of any commercial building energy audit is to analyze and understand a facility’s energy usage. Then to design appropriate strategies for making improvements that will reduce energy input and ultimately save money.

The Energy Audit Process

Emerald Skyline’s team is trained to assist property owners and facility managers understand their buildings and discover the greatest opportunities for energy savings.  We specialize in energy management solutions and discover the greatest opportunities for energy savings. The energy audit process allows us to determine what systems are causing you the most money on your utility bills.

Review Historic Utility Bills

To begin our process, we collect facility’s historic utility bills to determine the facility’s annual energy consumption.

Examine Existing Assets

Next, our team collects on-site data by performing the energy audit. During this time, we are determining potential solutions that maximize savings.

Present Economic Solutions

After we complete the audit and compare the utility bills, our team works together to design comprehensive systems custom tailored to each individual facility that maximizes energy savings.

 Mechanical Systems

HVAC units, boilers, hot water heaters, chillers, and more to determine current state of equipment, age, life expectancy, and performance.

Interior and Exterior Lighting

Lighting technology has increased significantly over the years. With LEDs not only do you improve lighting quality, but significantly reduce electric usage

Thermal Boundaries

The building envelope (windows, insulation, roofs, etc.) seal is essential to keep your conditioned spaces from leaking air. Ensuring proper insulation throughout the facility is key to minimizing heating and cooling costs.

Destratification Fans

In facilities with tall ceilings, maintaining consistent airflow helps maintain comfort in the facility.

Every facility is custom and operates differently. Our team has audited facilities across many industries from retail, hotels, offices, multi-family, and more. We have an expanded knowledge on systems and are flexible to tackle any project. In this time of uncertainty, it is important to keep operating expenses to a minimum. Unnecessary costs include costs for energy that you do not need to use. An energy audit will help determine the best energy conservation measures for your building.

COVID-19: The Wake-Up Call The Energy Sector Needed

Perhaps Henry David Thoreau was onto something when he set out solo for a cabin in the woods with the aim of becoming completely self-sustainable – for one, he wouldn’t really need to stress about a contagious pandemic. 

Thoreau’s experience would later shape the 19th century literary classic Walden; or, Life in the Woods, detailing how he was able to rely solely on himself, including growing his own food and sourcing firewood for heat and light at night. 

Whether he knew it or not Thoreau was excelling at social distancing and we could all take a leaf out of his book. 

Because, while most of us have got the idea of self-isolation down pat, I bet few are likely to pass the self-sufficiency test.

You only have to look at recent purchasing trends to see some of the panic stemming from a lack of self-sufficiency to see this ‘test’ in action. 

First it was the toilet paper and tinned food, before spreading to plants, with a nursery’s months-worth of vegetables and seedlings stock sold over one weekend. 

Next up: renewable energy infrastructure, as demonstrated by one solar retailer experiencing a 41 percent jump in PV sales and a 400 percent increase in battery enquiries over the past two weeks. 

But where were these eco warriors, cultivating their own veggie patches and living ‘off-grid’ before the apocalyptic hysteria hit? 

If history is any proof, crises are often the perfect kindling for igniting change, especially when standards of living are threatened. 

And the COVID-19 crisis has certainly given the energy world a wake-up call when it comes to sustainability.  

Mother nature gets a well deserved break 

Amid coronavirus-induced lockdowns, shutdowns and working from home, air pollution has significantly dropped worldwide.

In New York, carbon monoxide levels, largely produced from cars, have fallen by nearly 50 percent compared with the same time last year. 

Greenhouse gas emissions in China have also plummeted with NASA releasing images where you can see the country’s reduction in nitrogen dioxide from space.

According to one analysis, the slowdown of economic activity in China led to an estimated 25 percent reduction in carbon emissions in just four weeks. 

The restriction on air travel, or any travel at all, has also clearly played a role in reducing pollutants.

And whether you choose to believe the stories of wildlife returning to cities, like dolphins and swans returning to Venice canals, coronavirus has certainly given mother nature a well-deserved moment of respite. 

However, this has been at the expense of economic development, of jobs and livelihoods – and it’s certainly not going to be long-term. 

Air pollutants will likely jump once day-to-day normalities resume. 

However, if we’re smart about it, we can use this period to re-evaluate our energy systems to help flatten the emissions curve and keep our air clean.

Energy systems under pressure 

Aside from the closure of factories and reduction in fuel-consuming transport, we can’t forget that data centers and server-farms are also huge energy-intensive industries. 

Collectively, these spaces represent approximately two percent of the United State’s total electricity use. 

In the UK, there’s been reports of home-working intensifying pressure on the electricity network, instead of being in the office where lighting, heating and cooling are shared. 

Now everyone’s either working from home, or just at home, internet use and streaming is peaking. 

A study by SaveOnEnergy estimated energy generated from the 80 million views on Netflix’s NFLX thriller Birdbox was equal to the equivalent of driving more than 146 million miles and emitting just over 66 million kilograms of CO2 – what it takes to drive from London to Istanbul and back 38,879 times. 

Beyond the environmental impact, coronavirus has brought more attention to the question of whether our current energy systems and frameworks can actually keep up with increasing demand pressures.  

Several country-appointed energy councils have met to discuss electricity demand pressures related to COVID-19, with renewable energy a popular topic. 

In a meeting between Australia’s federal, state and territory energy ministers, the transition towards a genuine two-sided market was emphasized – where consumers become prosumers by contributing excess rooftop solar and battery electricity to the grid.

This would play a large role in forming a ‘day-ahead’ market, to “address concerns that managing challenges like system strength is becoming increasingly difficult with only a real-time market”. 

On top of this, the Australian Government’s Economic Response to the Coronavirus actually includes tax deduction incentives for commercial and industrial solar PV, in a bid to help alleviate financial pressure through reduced electricity bills. 

Digital transformation is underway across the energy sector, with significant advancements in renewable energy technologies and the ways in which energy is distributed. 

For any real change to occur, you need people to switch perspectives.

Powering new mindsets

Tough times spark innovation. Now is as good a time as any to test new energy systems and processes, and it starts with a shift in thinking. 

Energy networks, retailers and operators have delivered services in much the same way for a century – driven by fossil-fuels. 

New technology is making it easier, more effective and affordable to use renewable energy, and the costs associated with installing those technologies, such as solar and batteries are decreasing.

And most industry players recognise the need to change and evolve in order to remain relevant, or are at least are starting to, with a little nudge from COVID-19. 

Self-generating renewable energy infrastructure gives people the power to become self-sufficient for their electricity needs, with some even going ‘off-grid’ altogether. 

National Energy Market retailer Powerclub is one company already trialling new technology to help alleviate demand pressure on the grid via a Virtual Power Plant (VPP) in South Australia and is currently calling for more households to join. 

The VPP enables Powerclub households with batteries to sell their stored, excess solar back to the grid during peak demand periods and price hikes, via peer-to-peer energy trading technology. 

There is a huge benefit to the broader community in that the VPP gives those who may not be able to afford solar panels, or those who are renting, the opportunity to access clean energy. 

As great as it is to think of only the environmental benefit that comes with using clean energy, a monetary incentive certainly makes the proposition more appealing. 

Not only does a VPP provide renewable energy infrastructure owners with a passive income, it can also provide an incentive for others to install solar panels – knowing they’ll be able to pay back their investment faster. 

Pair a VPP with home grown vegetables and you’re a little closer to achieving Thoreau’s vision for self-sufficiency. 

Where to from here? 

At the end of the day, it shouldn’t take a pandemic for people to reconsider their impact on the environment – but it has. 

We’re now being given a chance to press reset on many areas of our lives and reconsider what it takes and what choices to make in order to lead a more sustainable lifestyle. 

Energy regulators are on the right track with numerous initiatives and policy changes currently underway.

But you could make a change right now – how we return to normal life post COVID-19 could lay the foundations for a cleaner and more resilient energy future.

Why does that matter? Well, as Thoreau said; “What is the use of a house if you don’t have a decent planet to put it on?”

Tesla delivers 88,400 electric vehicles, beating expectations

Tesla delivered 88,400 vehicles in the first quarter, beating most analysts expectations despite a 21% decrease from the previous quarter as the COVID-19 pandemic put downward pressure on demand and created logistical challenges.

Tesla said Thursday it produced 103,000 electric vehicles in the first quarter, about 2% lower than the previous period.

The deliveries and production figures beat most analysts expectations, causing Tesla shares to jump more than 10.4% in after-hours trading. Analysts, who had anticipated lower numbers due to the COVID-19 pandemic, had varying forecasts. A consensus of analysts by FactSeat expected more than 79,908 vehicles would be delivered while Reuters reported IBES data from Refinitiv forecast numbers as high as 93,399 vehicles.

The company, which sells directly to consumers as opposed to using dealerships, was able to beat those expectations in part because it continued to produce and deliver its electric vehicles to customers in spite of the COVID-19 pandemic. The pandemic has prompted city, county and state officials to issue stay-at-home orders that have directed non-essential businesses to close. While manufacturing is often exempt from these orders, pressure from the United Auto Workers as well as falling demand has prompted automakers, including GM, Nissan, Ford, Fiat Chrysler Automobiles, Toyota and Volkswagen suspended production at all U.S. factories.

Tesla also suspended production, beginning March 23, at its plant in Fremont, Calif. However, deliveries have continued.

While COVID-19 still affected Tesla, the company still managed to beat its delivery numbers from the first quarter of 2019.

Here’s a breakdown of the first quarter 2020 deliveries and production:

  • Tesla delivered 88,400 vehicles (compared to 112,000 in Q4 and 63,000 in Q1 2019)
  • Tesla produced 103,000 vehicles (compared to 105,000 in Q4 and 77,100 in Q1 2019)

This quarter deliveries included some Model Y vehicles, the newest addition to Tesla’s portfolio. Model Y production started in January and deliveries began in March according to Tesla.

Tesla also said that its new Shanghai factory, which is producing the Model 3 for Chinese customers, is achieving “record levels of production, despite significant setbacks.” Tesla didn’t provide any details on the levels of production at the Shanghai factory. The first public deliveries of Model 3 sedans produced at its Shanghai factory began January 7, one year after Tesla began construction on its first factory outside the United States.
