Residential IAQ Guide

ASHRAE Journal, Mar. 2016, by Lawrence J. Schoen.
http://bookstore.ashrae.biz/journal/download.php?file=2016Mar_080-081_IAQ_Schoen.pdf

"This column previews the Residential Indoor Air Quality Guide that ASHRAE will publish early in 2017. The new guide will be a companion to the affordable Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning that ASHRAE published in 2009, which focused primarily on nonresidential indoor air quality."

Health, Wellbeing and Productivity in Retail: The Impact of Green Buildings on People and Profit

World Green Building Council, Feb. 2016.

"The report’s main finding is that retailers can improve the shopping experience for their customers and potentially increase their profits by providing greener, healthier stores."

Direct-Fired Technology: From Makeup Air to Space Heating

ASHRAE Journal, Sep. 2015, by Thomas Boeckermann, and others.
http://bookstore.ashrae.biz/journal/download.php?file=2015Sept_016-027_Kuehn.pdf

"Direct-fired heating technology is a safe, energy-efficient, and cost-effective means to provide heating for a wide range of applications. The two main uses—makeup air and space heating—have different applications and require different approaches to deliver the most efficient design. This article summarizes the basic operating principles, safety, energy performance, psychrometric behavior, and recommendations for the use of direct-fired heating units."

Pacific Northwest Residential Ventilation Effectiveness Study

Northwest Energy Efficiency Alliance, Sept. 14, 2015, by Ken Eklund and others.

"This report presents the findings and conclusions of the Pacific Northwest Residential Ventilation Effectiveness study in houses with low air leakage. The Northwest Energy Efficiency Alliance (NEEA) commissioned the Washington State University (WSU) Energy Program to conduct the study, which included a total of twenty-nine houses in Washington State with five different types of ventilation systems. Exhaust ventilation (Exhaust Only (EO) and Exhaust with Inlet Vents (EI)) and heat recovery ventilation (HRV)/energy recovery ventilation (ERV) systems made up the largest share of the ventilation systems studied."

Indoor Air Quality in Hospitals

Consulting-Specifying Engineer, July 2015, by Christopher J. Stipe.
http://www.csemag.com/single-article/indoor-air-quality-in-hospitals/b4a355bfbd61c4902f08216c20be3e8e.html

"Hospitals and health care facilities must comply with ASHRAE and other regulatory standards with respect to air change rates, humidity requirements, and pressurization. ASHRAE Standard 62.1 is the most commonly referenced standard to meet appropriate HVAC system design. Other factors to consider include the use of UV light to reduce hospital-acquired infections, unique air requirements, and outdoor air systems."

Study Suggests Residential Pellet Offgassing a Nonissue

Biomass Magazine, Aug. 12, 2015, by Anna Simet.
http://www.biomassmagazine.com/articles/12297/study-suggets-residential-pellet-offgassing-a-nonissue

"According to results from a new study released by the University of New Hampshire, indoor storage of pellets in homes using the fuel for heat does not pose a risk of generating carbon monoxide (CO) levels above recommended thresholds. The issue has been contentious in the Northeast, said Adam Sherman, executive director of Vermont-based Biomass Energy Resource Center."
