Increasing the energy efficiency and reducing the energy consumption of existing buildings can have four times the environmental impact as compared to the installation of renewable energy.
With existing building renovation accounting for most of the money spent in U.S. building construction today, actual building performance needs to be determined to make the most of those dollars spent. Setting those metrics and increasing existing buildings’ energy efficiency is described in a seminar at the ASHRAE 2016 Annual Conference.
The Conference takes place June 25-29, Marriott St. Louis Grand Hotel and America’s Center Convention Complex. To register or for complete information, visit www.ashrae.org/stlouis.
In 2015, ASHRAE and the Illuminating Engineering Society published ANSI/ASHRAE/IES Standard 100, Energy Efficiency in Existing Buildings, which goes beyond energy efficiency minimums in that it requires energy management and operation and maintenance plans.
“By requiring energy audits and providing for life cycle cost analysis of potential energy efficiency measures, the standard gives building owners the tools and opportunity for even higher performance,” Gordon Holness, who helped write the standard, said.
Holness is a speaker at a seminar at the Conference, Standard 100-2015 Overview and the Potential of Its High-Performance Existing Building Metrics, which takes place June 29.
The standard sets specific energy targets based on building type, occupancy and climate zone with target tables established based on the top 25 % performers within the U.S. Department of Energy’s Commercial Building Energy Consumption data base. On an aggregate basis the standard is expected to reduce building energy use by approximately 30 %.
“The standard recognizes that U.S. annual investments in renovation of existing buildings account for around 86 % of all money spent in building construction today,” he said.
The seminar is one of 108 sessions in the Technical Program, which is organized into eight tracks that will cover topics such as current trends and technologies in the industry; professional development and residential systems; new design strategies for achieving net zero buildings; high energy efficiency and methods of design, including recent advances in alternative energy systems and equipment. The program features more than 400 speakers.
