"After decades of the old terminal velocity standby, it may be time to do away with “We’ve always done it that way.”"

A New Spin On VRF & Ventilation [in a School]

Engineered Systems, Feb. 2017, by John Parris Frantz.

"A Tennessee district faced an old school HVAC challenge: aging ventilators and space constraints. So this team tried a new-school variation on common VRF retrofits to deliver improved efficiency and critical IAQ: they decentralized the outdoor air, combining enthalpy wheel and VRF components within a single classroom enclosure."

Can Energy Efficiency and Health Industries Bring Momentum Mainstream?

E4TheFuture Blog, Jan. 12, 2017, Julie Michals.

"When E4TheFuture decided to explore the health co-benefits of energy efficiency in its November 2016 white paper Occupant Health Benefits of Residential Energy, we had a particular reason for doing so. Our initial focus was to document studies that could help inform cost-effectiveness screening—specifically, to help make the case that important health co-benefits of efficiency exist, and their value is not $0. We were excited to piggyback on a broader research effort undertaken by the US DOE."

Specifying HVAC Equipment in Critical Environments

The Construction Specifier, Dec. 2016, by Matt Strong.

"Cleanrooms present unique design challenges because they must meet specific requirements that go beyond what is encountered in a typical commercial space. When specifying HVAC equipment in a critical environment such as a cleanroom, engineers must consider the key issues of air filtration, humidity control, and pressurization. While a specifying engineer may have experience with these issues in the context of a traditional commercial application, the considerations are substantially different in a cleanroom."

Home RX: The Health Benefits of Home Performance: A Review of the Current Evidence

Prepared by the National Center for Healthy Housing (NCHH) for the U.S. Dept. of Energy, EERE, Dec. 2016.

"The home performance industry supports whole-house solutions to improve home energy use and enhance indoor air quality and environmental conditions. Numerous studies have evaluated the effects of a range of residential energy efficiency and green renovation work on indoor environmental quality and occupant health. However, there has not been a systematic review of such studies to summarize current knowledge and identify research gaps."

Weatherization Plus Health in Washington State: An Update

National Association for State Community Services, Oct. 26, 2016.
https://thestateofpoverty.org/2016/10/26/weatherization-plus-health-in-washington-state-an-update/

"In April, we described the launch of an exciting new weatherization venture in Washington State that combines the energy efficiency improvements of weatherization with a targeted approach to reduce and remove asthma triggers in low-income households. Six months later, the hard work of marrying weatherization to home health environment improvements is underway. The Washington State Low-Income Weatherization Assistance Program is learning a great deal about the challenges, and the promise, of energy savings and health impacts in low-income homes."

Know When, Where to Specify VRF Systems

Consulting-Specifying Engineer, Sept. 2016, by James M. Del Monaco.

"Variable refrigerant flow (VRF) offers an alternate HVAC solution. Its key attributes include zonal control, energy efficiency, and indoor air quality (IAQ). To help facilitate their successful design and operation, engineers should take advantage of the available resources and training offered by manufacturers, utilities, and others."

Classroom Ventilation: Meeting Today's Challenges

Engineered Systems, May 2016, by Steven G. Liescheidt.
http://www.esmagazine.com/articles/97718-classroom-ventilation-meeting-todays-challenges

"Budgets, codes, and technologies are constantly shifting and evolving. These days, even the classrooms are often portable. Staying one step ahead will depend on your knowledge of current design options and how to integrate them into the space."

Unique Approach to High-Efficiency Laboratory-Exhaust Energy Recovery

"The addition of adiabatic/evaporative exhaust cooling to a laboratory run-around-coil heat-recovery system at the College of Charleston [SC]."

Case in Point: School District Aces Efficiency, Flexibility with VRF

Engineered Systems, May 2, 2016.
http://www.esmagazine.com/articles/97709-school-district-aces-efficiency-flexibility-with-vrf

"Several schools in the Hazelwood School District north of St. Louis were retrofitted with heat recovery systems. This allowed some schools to reduce installed tonnage by up to 50% and also gave teachers greater control of classroom comfort."
