Continued: Can HVACR technology cost-effectively boost supermarket energy efficiency in the future?

In a previous post, we considered the incremental efficiency improvements possible for supermarkets through existing technologies. However, even bigger energy savings can occur when technologies and services make connections outside the store. In fact, managing multiple stores across the enterprise multiplies the energy savings.   Option 2: Efficiency improvements through connectivity To get actionable, real-time

Can HVACR technology cost-effectively boost supermarket energy efficiency in the future?

Over the last two decades, residential HVAC systems in the US have gone from 10 SEER to 15 SEER — a 25% improvement. For commercial buildings, the source and site-energy-use efficiency improvements in ASHRAE 90.1 standards have increased more than 40% — with corresponding reductions in CO2 emissions. But, HVAC and refrigeration equipment use 50-60%

Variable speed everything

Over the past few years, it seems I’ve been able to increasingly recite what has become one of my favorite mantras: “variable speed everything.” This is in part because, on a national level, there has been a growing conversation around doubling U.S. energy productivity by 2030. Reaching that goal will undoubtedly require a strong focus
