"While times are hard now for many schools, some manufacturers believe an improving economy and increasing availability of alternative financing options will soon make it easier for schools to get the funding necessary for upgrades. And, in the meantime, HVAC products will continue to improve in energy efficiency, ease of installation, and life cycle."

Wood-Pellet-Fired Boilers Provide Highly Efficient, No-Fuss Operation

Heating/Piping/Air Conditioning Engineering, June 2014, by Dan Vastyan.
http://hpac.com/heating/wood-pellet-fired-boilers-provide-highly-efficient-no-fuss-operation

"The Pennsylvania Department of Conservation and Natural Resources (DCNR)...wanted a district hydronic heating system fired by a renewable fuel—ideally, wood for its Resource Management Center—in Weiser State Forest in eastern Pennsylvania.

After reviewing several proposals, the DCNR chose a solution offered by ATI Systems Inc., a hybrid representative/distributor/engineering-services organization based in Conestoga, Pa., whose founder, Carl Longenecker, has found a way to burn wood automatically at near-condensing efficiencies with an air-friendly emissions profile vastly beyond traditional wood and coal burners

High-Efficiency Condensing Boilers for Multifamily Applications

Heating/Piping/Air Conditioning Engineering, June 2014, by Tracy Young.
http://hpac.com/heating/high-efficiency-condensing-boilers-multifamily-applications

"Just over a decade ago, a new heating/heating-and-water-heating option for multifamily dwellings arrived in North America: the high-efficiency wall-hung condensing boiler. A standard in Europe for many years, these units save space and reduce utility bills while continuously providing heat and hot water to tenants. Units decrease utility bills, boost tenant satisfaction."

Glazing Systems: Considerations for the Mechanical Engineer

Consulting-Specifying Engineer, June 2014, by Jerry Bauers and George W. Houk.

"Window glazing and shading or louvers have a direct impact on the HVAC load of a building. Mechanical engineers often are tasked with specifying window and shading systems. Know about building envelope, and how it can be managed/altered by window system selection."


Taming an Energy Hog with Efficiency Standards [Furnace Fans]

American Council for an Energy-Efficient Economy (ACEEE), June 25, 2014, by Joanna Mauer.
http://aceee.org/blog/2014/06/taming-energy-hog-efficiency-standard%20

"The Department of Energy (DOE) issued new efficiency standards today that will dramatically reduce the energy use of a little-known home energy hog. Furnace fans, which circulate heated and cooled air throughout a home, consume more than twice the electricity in a year as a typical new refrigerator. The new standards will cut the cost to power furnace fans by about 40% and also deliver improved comfort."
