Energy efficient design is more than just choosing equipment with the highest energy efficiency rating. Real world building operating conditions must be accounted for to ensure energy savings. Energy modeling, not nameplate ratings, is key to specifying equipment that will yield the highest energy and...
We recently released an update to our R package, nmecr. This version provides a bug fix and vignettes for the R code. is an open-source set of tools for analyzing commercial building energy consumption using a meter-based, whole-building approach for measurement and verification (M&V) of...
For my 2020 resolution I’m making a pledge to take action and reduce my carbon footprint, and I hope that you’ll join me. I’m making a real, concerted effort this year to reduce my carbon footprint as low as I can get it. That means...
If you reside outside the world of energy efficiency, you might not be familiar with an energy audit. Perhaps you just want to reduce operating expenses by lowering your utility bills? Maybe you need to meet corporate sustainability goals? An energy audit can be the...
When you get a bunch of energy engineers in a room you’ll start hearing a lot of acronyms like Cx, RCx, and MBCx to name a few. It can be overwhelming to anyone not living and breathing building energy efficiency. So, let’s break down what...
Your employees may be on vacation but your computers and office equipment don’t get one, unless you give them one. With sparsely occupied offices over the holidays, it’s the perfect time to think about how your business can save energy and help the planet by...
We are very excited to announce that kW Engineering released open source R code today for analyzing site-level, meter-based energy savings. Our will make it much easier for energy efficiency program implementers to analyze energy efficiency project impacts using the normalized metered energy consumption (NMEC)...
There’s hardly any excuse anymore not to have an EV (electric vehicle), as a second or third car at least. If you are concerned about climate change, like a good deal, and live in a house in California, you should get an electric car, now. But...
Earlier this year, I wrote about the brand new Lab Benchmarking Tool we developed with our partners at LBNL, I2SL, and DOE. I’m pleased to report that we’ve gotten lots of positive feedback since the LBT’s release! We’ve also been busy developing new features to...
Commercial building heating, ventilation and air conditioning (HVAC) systems commonly use variable air volume (VAV) systems for their heating and cooling needs. VAV systems can be more energy efficient when properly controlled and operated. We frequently find these systems performing less than optimally and recommend...
