YORK YZ Magnetic Bearing Centrifugal Chiller is the first chiller to be optimized for use with a low-GWP hydrofluoroolefin (HFO) refrigerant.

January 7, 2020

Refrigerants are a unique problem in the green building world. Even the most energy-efficient chillers and heat pumps use them, and many of these refrigerants have global warming potential (GWP) more than a thousand times that of CO2. The “next generation” hydrofluoroolefin (HFO) refrigerants are a good solution, but if they are dropped into... Read more

If you thought doing an energy model on one building was hard, try a whole district. But NREL is going to make it easier.

December 2, 2019

In theory, district-scale energy systems are the future. But there’s a big problem: it is very difficult to model them—which in turn makes it difficult to design them. That’s now being rectified with the Urban Renewable Building and Neighborhood optimization (URBANopt), an EnergyPlus- and OpenStudio-based simulation platform being developed by... Read more
