Residential Systems to be Addressed at ASHRAE Winter Conference
Balancing energy efficiency and comfort in homes
ATLANTA — Over the last 15 years single-family homes have been built tighter, making them much more energy efficient and comfortable compared to drafty houses of the past. But there’s a tradeoff, which will be addressed in one of the residential sessions at the ASHRAE 2016 Winter Conference.
“While the energy benefits are great, air tight homes demand thoughtful HVACR design for ventilation and building pressure management,” said Lew Harriman. “The big issues involve adequate outdoor air for kitchen and bathroom exhausts and combustion appliances, plus the continuous ventilation now required by ASHRAE’s residential indoor air quality standard, 62.2.”
Air tightness is indirectly connected to IAQ because IAQ is connected to total ventilation, and leaky buildings can contribute to total ventilation. But it is much more energy efficient to provide ventilation mechanically vs. through air leakage, Harriman noted.
Harriman is chairing a session that addresses residential building applications at the ASHRAE 2016 Winter Conference, which takes place Jan. 23-27, in Orlando, Florida.
The seminar, High Performance Residential Building Applications and Issues, takes place Monday, Jan. 25. Experts from the natural gas industry, the U.S. Department of Energy (DOE), and Lawrence Berkeley National Laboratory will describe results of their decades of real-world experience measuring and understanding the behavior of tight houses. They will provide practical tips and traps to help both HVAC professionals and homeowners ensure safe, high quality indoor air in the tight, net-zero energy houses of the 21st Century, according to Harriman.
The seminar program is part of the Technical Program track on modern residential systems.
“Engineering for residential HVAC and plumbing systems and equipment used to be referred to as catalog engineering: for a two bedroom house choose one from Column A; for a three bedroom house choose one from Column B,” said Jennifer Leach, chair of the track and of the conference’s Technical Program. “Recent years have seen a boom in energy efficient solutions for the savvy, fiscally-conscience homeowner. From glazing to water heating to lighting, speakers in this track are going to provide updates on the latest advances for the residential market.”
