"The energy-efficiency ratings of residential air-source heat pumps have risen dramatically over the last few years, with many manufacturers now offering equipment well exceeding the 20-SEER mark. There have been significant gains made in commercial heat pump efficiencies as well, thanks to the growing demand from building owners and managers, who are looking for ways to save energy."

How to Design & Control Waterside Economizers

ASHRAE Journal, Jun 2014, by Steven T. Taylor.

"ASHRAE/IES Standard 90.1 requires either airside economizers or waterside economizers for most cooling system applications. Air economizers are more common and almost always more energy efficient. But there are some applications where water economizers are preferred."

Hydronic Heat Recovery in Health Care

"Over the years, HVAC engineers have been challenged to provide more efficient and sustainable designs that meet societal demands to reduce the overall carbon footprint of a facility. Performance guidelines provided by programs such as the U.S. Green Building Council, Green Globes, and Energy Star provide guidelines for energy efficiency, while agencies such as the Environmental Protection Agency (EPA) and the Dept. of Energy (DOE) establish compliance guidelines for commercial HVAC systems."

"Infosys, one of India’s top three software companies, implemented a program in 2011 to find the best way to cool its buildings, while creating lower energy buildings that better suited the needs of its employees. The resulting building, Software Development Block 1 (SDB-1) in Hyderabad, not only became the first radiantly cooled building in India, but also resulted in the world’s largest HVAC side-by-side comparison."



Saving Energy with Neighborly Behavior: Energy Efficiency for Multifamily Renters and Homebuyers

ACEEE, May 2014, by Kate Farley and Susan Mazur-Stommen.
http://www.aceee.org/files/pdf/white-paper/saving-energy-with-neighborly-behavior.pdf

A White Paper from the American Council for an Energy-Efficient Economy. "Tenant engagement programs encourage the people who live in a multifamily property to change their behavior in order to achieve a goal. These programs are an attractive option for owners or managers who want to improve energy efficiency. In this report, we assess the key features of existing programs, make recommendations for improvements that housing providers and advocates can use immediately, and outline a wish list for the future."
