The Next Green Challenge: Energy use in Existing Buildings

The Next Green Challenge

Posted May 23, 2008

Overview

The LEED green building rating system has set standards for new buildings, encouraging developers to greatly improve energy efficiency beyond the requirements of current codes. But the fact remains that most energy use occurs in already existing buildings. At the Academy's Green Buildings Discussion Group meeting on April 1, 2008, a panel of experts in energy efficiency explored the possibilities of reducing energy consumption by renovating existing buildings.

The stringency of building energy codes can play a major role in transforming our building stock, and simply bringing all existing buildings up to the more recent American Society of Heating, Refrigeration and Air Conditioning Engineers code could save 45% on building energy consumption. Monitoring a building's energy consumption by analyzing its past energy bills is the essential first step in making energy-efficient renovations. After renovations are made, energy bills must be monitored over time to verify that the retrofits saved energy and money.

Jeffrey Perlman is the president and founder of Bright Power, Inc. With Bright Power he has developed and managed photovoltaic, solar thermal, energy efficiency, and peak -demand-reduction natural gas generator projects as well as provided energy auditing services. He also works with the Association for Energy Affordability as both an energy auditor and project manager for the Greening A Block project.

Prior to founding Bright Power, Perlman worked as an independent consultant in energy efficiency, solar energy, and green buildings. His projects included co-authoring, with Greg Kats at Capital E, the ground-breaking report, The Costs and Financial Benefits of Green Buildings, which used economic cost/benefit analysis to show that building healthy, energy-efficient, and environmentally responsible buildings makes economic sense, too. Other projects have included assessment of new solar technologies, business plan development and financial/market analysis. Perlman is a LEED-accredited green buildings professional and has received training as Building Performance Institute BA-I and Shell Specialist (he did not pursue these certifications because his focus shifted from residential to commercial buildings). He has a degree in applied physics from Yale University.
