I can’t tell you how happy I am that I can say that ASHRAE Standard 211 – the world’s first comprehensive standard for energy audits – is out! This news might come as a surprise to some – most people treated the energy audit levels defined...
As energy engineers looking for potential energy savings during energy audits, retro-commissioning investigations and ongoing commissioning, we typically use trend reviews to evaluate the effectiveness of control logic. Trends offer a window into what the controls accomplished in the past. They need to be interpreted...

It’s helpful for stakeholders to understand how they are different to be sure expectations are aligned and construction moves smoothly. Commissioning is a SYSTEMATIC process, not a...
‘You can’t manage what you don’t measure’ is a keystone of energy efficiency. Measuring your building’s energy use is so important that reporting it is now the law in California for many building owners. The first deadline is quickly approaching beginning on June 1, 2018....
The initial novelty of solar may have passed, but as renewables become mainstream, costs decrease, and legislation pushes for clean energy, there are still savings to be had provided systems are well-designed and continue to operate as intended. After inspecting over 3,000 PV systems in Central...
