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...

Much of what we do in the energy industry feels very esoteric. So, whenever an opportunity presents itself to incorporate work from other disciplines, like data science, I get really excited. That is what’s happening with ASHRAE Great Energy Predictor Challenge III that just launched...

Unfortunately, in the world of building design, feedback is often lacking. Most architects and engineers work on new buildings, and once commissioning is done, there’s little opportunity (or budget) to review the impact of design choices, positive or negative. Without a feedback loop from commissioning...

Did you know your business could receive incentives or no-cost technical support to investigate and implement energy-saving projects in your building? Utilities offer and procure energy efficiency programs to increase building energy efficiency. The goal of these program is to save energy by resolving inefficient...

There are many tools of the trade in the world of building energy efficiency. Knowing the difference between approaches, like the difference between a commercial building energy audit and retro-commissioning, can help you take the next best step to lower your energy bills, while meeting...
