Energy Benchmarking and Transparency Policies Are Driving Efficiency in Urban Buildings

Currently, 282 cities have signed on to the ‘We Are Still In’ Group, and in support, the C40 Cities initiative (now actually 94 cities around the globe) and American Cities Climate Challenge are just two of the organizations that provide for cities to share best practices. Among those best practices are energy benchmarking and disclosure

Are we Getting Closer to Allowing the Use of Flammable Refrigerants?

One of the barriers to the new refrigerants is the recognition of flammable refrigerants in building codes. Codes dictate so much about building construction and what mechanical equipment can be used. There are codes for fire protection, building construction, mechanical systems, and other aspects of buildings; all affect the HVACR system. A good article on

The Role of Design in Innovation and Sustainability

Henry Ford once said, “You can have any color you want as long as it’s black”—a slogan that launched the early industrial model. And still today industry relies on economies of scale—and scaling means as little product differentiation as possible within a product line. Industrial efficiency thrives on product commoditization, but in a competitive global

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%
