This past June, Klas Haglid of Haglid Engineering attended the ASHRAE Annual Conference in Houston, TX. I always recommend attending these kinds of advanced learning events. They will help you in your job and your career! I did not attend this year as I was speaking across the state at the BOMA International Conference and Expo in San Antonio. So while I could not be there in person, I am grateful for the other industry leaders like Klas who attend and share their key takeaways with us.

Why Your Energy Star Rating May Go Down in 2018

And What You Can Do About It in 2017

The good news is that EPA’s Energy Star Portfolio Manager is getting a much needed data update.

The bad news is that it may cause some Energy Star scores to go down.

How Portfolio Manager Works

ENE_prt_v_c.jpgAs you probably know, Energy Star Portfolio Manager (ESPM) is a well-known and widely used program for comparing energy use among existing buildings. Building owners and managers use ESPM to see how well their building performs with regards to energy use. The ESPM rates the building on a 1-100 scale against buildings of similar size and use. It also takes into consideration climatization so that buildings in different climate zones can be compared with each other. 

Energy Star requires a score of 75 or better to earn Certification. For details, click here. If your score is below 75, or you would like to see a higher score – and lower utility bills – consider implementing some low-cost or no-cost Energy Conservation Measures (ECMs) with relatively fast paybacks. Other ECMs might be more expensive with long paybacks. In that case you may want to consider alternative financing, such as Property Assessed Clean Energy, or PACE (Click to learn how PACE can help you.)

Is Energy Star Going Away?

Note: Since this was article was originally posted, a budget passed Congress that does not significantly reduce EPA funding. So we believe the Energy Star Program is safe - for now. It’s good to know, however, what else is out there from the private sector, for example, ASHRAE bEQ as is discussed below. Our industry needs to be well-versed in all the options, not on a just-in-case basis, but on a what’s-best-for-the-customer basis. (updated 5/10/2017)

Since its inception in 1992, the Energy Star label has gained tremendous popularity, and today thousands of products (mostly small and medium home appliances) sport the Energy Star logo. Use of this program, run by the US Environmental Protection Agency (EPA) in partnership with the US Department of Energy (DOE), had saved $362 billion on energy bills and prevented nearly 2.5 billion tons of greenhouse gases from being released into the atmosphere. If this program goes away, as is being proposed by the current administration, we risk losing many of the gains that have been made.

Sizing Up Equipment Selection for Energy Efficiency

Energy Recovery Ventilators Can Enhance Indoor Air Quality While Saving Energy and Money

FRESH AIR FUNDAMENTALS. Fresh air being key to good health, it's a shame we cannot rely on the supply and quality of our indoor air these days. Thanks to technology, our building envelopes - the physical separation between the interior and exterior of a structure - have grown significantly tighter. One hundred years ago people enjoyed generous amounts of OA (Outside Air) flowing through gaps in doors, windows, joints, and cracks. A cool draft through an old building was typical and necessary for a good ghost story. However, the cost of energy and technology has changed our perspective on drafts as well as mechanically cooled or heated air. We don't want to pay extra to heat or cool more air than we have to due to excessive outdoor air coming in or conditioned air leaving the building before delivering its full potential. Tighter envelopes lessen the avenues for air entry and escape in order to achieve energy savings. So ... tighter envelopes that reduce energy costs as well as the amount of emissions fleeing into the atmosphere is a good thing, yes? Naturally, but as with most things, you can have too much of a good thing.

According to the EPA, "Indoor levels of pollutants may be 2 to 5 times - and occasionally more than 100 times - higher than outdoor pollutant levels {and} have been ranked among the top five environmental risks to public health."

What’s Preventing You From Having an Energy Audit?

Energy audits are one of the best ways to discover money-saving opportunities in an existing building. A commercial or industrial energy audit, also called an energy analysis, will identify how much energy a building uses, how efficiently it uses that energy, and where changes and improvements can be made that will impact both the occupant comfort and the bottom line.
