Mayor Larry Klein of Palo Alto had his house checked for energy efficiency to determine his "carbon footprint" Wednesday.
It leaks energy, consultant Suzanne Emerson of San Carlos-based Emerson Environmental concluded in a four-hour examination of about everything energy-related that goes into a house.
Klein and other city leaders have vowed to reduce their "carbon footprints" by 10 percent, and the check of his house will establish a baseline.
One of the bigger tests involved sealing a door between house and the garage and creating a "blower door" with a large fan sucking air out of the house.
Emerson then felt for leaks around switches, plugs, windows, doors and joints, either by hand or using a smoke-producing stick device.
Emerson, who has a law degree, left an environmental law practice in a large firm after 13 years to found Emerson Environmental -- after she struggled to make her 65-year-old home more energy efficient.
Other elements of her "greening" a home inspection include checking types of lighting and even which fluorescent bulbs are best; recommending insulation types; looking for "passive" drains on energy from certain types of dimmer switches and other sources; and other items.
Klein appeared pleased with the process. One way of looking at the inspection would be that the more energy leaks are found the easier it will be to get to a 10 percent reduction.
