A Comprehensive Look at the Intelligent Building

Consulting-Specifying Engineer, Apr. 2016, by Steve Brown, Kurt Karnatz, and Rob Knight.

"Technology is changing what’s possible for buildings. With the advent of smart building technology, heating, cooling, electrical, lighting, fire/life safety, and other systems need monitoring and intercommunication for optimized efficiency and operation."

Should we Promote Heat Pumps to Save Energy and Reduce Greenhouse Gas Emissions?

American Council for an Energy-Efficient Economy, May 4, 2016, by Steven Nadel.
http://aceee.org/blog/2016/05/should-we-promote-heat-pumps-save

"In order to examine which applications are good for obtaining cost-effective energy savings from heat pumps, ACEEE conducted a pair of analyses that we are releasing today. One addresses opportunities to replace electric resistance heat with heat pumps and the other addresses replacing gas furnaces with heat pumps."

High-Performance High-Rise

Building Operating Management, Apr. 2016, by Saied A. Nazeri.

"The HVAC system at 350 Mission [San Francisco] aims for top marks in both energy efficiency and occupant satisfaction."

Data Centers and Ab/Adsorption Chillers

Engineered Systems, Apr. 2016, by Marcia Karr.

"A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation."

Rooftop Refrigeration Unit Performance

ASHRAE Journal, Apr. 2016, by Kenneth M. Elovitz.

"Diagnosing a rooftop air-conditioning equipment performance problem requires analyzing complete refrigeration system performance data. The systematic approach described in this article resulted in replacing orifice-type metering devices with a traditional thermal expansion valve—and remedying insufficient dehumidification."

A Simple Approach to Affordable GSHPs

ASHRAE Journal, Apr. 2016, by Steve Kavanaugh and Chris Gray.
http://bookstore.ashrae.biz/journal/download.php?file=2016Apr_014-025_Kavanaugh.pdf

"Conventional wisdom says ground source heat pumps (GSHPs) should not be considered for commercial and institutional buildings because of the added cost. This article investigates how building owners leasing the ground heat exchanger can make GSHPS affordable for commercial and institutional applications."

Wood Alternatives to Fossil Fuels [Wood Pellets]

Buildings, Mar. 2016, by Janelle Penny.
http://www.buildings.com/news/industry-news/articleid/19958/title/wood-alternatives-to-fossil-fuels.aspx

"Could scraps from sawmills and furniture manufacturers become an affordable, eco-friendly heating option for your facility? Wood chips and pellets – a compressed form of wood-based waste that resembles rabbit feed – are growing in popularity as a green replacement for conventional heating fuels."

Design Considerations for Dedicated OA Systems

ASHRAE Journal, Mar. 2016, by Hugh Crowther and Yi Teng.
http://tinyurl.com/h4xlwh2

"Dedicated outdoor air systems (DOAS) decouple the heating, cooling, dehumidification and humidification of outdoor air from the space air-conditioning system. Common HVAC systems such as water (ground) source heat pumps, variable refrigerant flow (VRF), fan coils and chilled beams require a DOAS to meet ventilation requirements. But DOAS is a system, not a piece of equipment."

The Ultimate Biomass Heating Package [in a School]

Biomass Magazine, Mar. 2016, by Ron Kotrba.
http://biomassmagazine.com/articles/12891/the-ultimate-biomass-heating-package

"Via a contractual arrangement unique to biomass heat in the U.S., Wilton, New Hampshire-based High Mowing School replaced fuel oil with a biomass district heating system from Xylogen."

Absorption Chillers For Institutional Occupancies

Engineered Systems, Feb. 2016, by Marcia Karr.
http://www.esmagazine.com/articles/97567-absorption-chillers-for-institutional-occpancies

"It's not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success."
