Bob meets with Peter Merianos and the crew from Coastal Heating and Air Conditioning who are fabricating the AC ductwork on site. With the Kenmore air handler already installed in the attic, the crew begins assembling the ductwork using five-foot lengths of pre-crimped sheet-metal ducting as the basic material. The sections snap together and are secured with sheet-metal screws and foil tape. To add a new line off the main trunk, the crew cuts a hole into the the trunk with a special tool. A starting collar from which the new line will extend is then inserted into the hole. The ductwork is insulated using vinyl wrap, which is a one and a half-inch vinyl-coated fiberglass blanket.

Guardian Industries' Performance Plus II Low-E can save significant energy dollars when incorporated into a window such as the Philips Marquee 9000. This high performance low-E coating is designed to keep heat where you want it, so warm rooms stay warm in the winter, and cool rooms stay cool as the summer sun is reflected away from conditioned interior spaces. Homes with high performance low-E glass use less heat in the winter and less air conditioning in the summer, resulting in significant consumer energy savings.

Insulation contractor Rick Davenport shows Bob how they install wet-spray cellulose insulation into open walls. The material is typical cellulose insulation, simply recycled newspaper. It's the installation system that is unique. Small jets of water moisten the insulation as it leaves the nozzle of the blower hose. The damp cellulose sticks to the studs and exterior sheathing, completely filling the wall cavity. The moisture will dry before the interior drywall is installed, so it doesn't harm the wall or affect the insulation value of the material. A large rotating brush, called a stud scrubber, removes excess material and cleans the inside face of the stud. In the ceiling, a blown-in-insulation is used. Plastic netting has been stretched along the bottom surface of the ceiling joists to support the material. The end of the blower hose is inserted through the netting to fill the cavity. Instead of adding water as the cellulose leaves the hose, an adhesive binder is mixed with the cellulose before it leaves the hose. The binder helps achieve a controlled density that provides a uniform insulation level of R-3.7 per inch, which comes to R-37 in this 10-inch cavity.

John Livermore joins Bob to explain the Energy Star Homes program started in the 1970s by the U.S. Environmental Protection Agency. The red blower door is in place to do the blower door test required for certification as an Energy Star Home. Certified homes must be at least 30 percent more efficient than the model energy efficiency code. Once certified, homeowners and builders are eligible for rebates and services from a consortium of utilities and energy service providers. Livermore reviews key areas of energy-efficient building with Bob, including air sealing. He repeats the builders' motto, "build tight and ventilate right," when discussing the importance of a tightly sealed home with proper air exchange. Livermore shows Bob a light expansion foam that can be used with a foam gun to seal against air leaks around doors and windows and the Panasonic Whisper Light fans that bring air changes to the home at a controlled ventilation rate. Another energy saver is the programmable thermostat that allows homeowners to schedule heat for waking hours of occupancy. Compact fluorescent lights are also used throughout the home because they use 70 percent less energy, have a lower heat output and last longer than traditional incandescent bulbs.

Bob meets paint-stripping expert Bob Sharon and looks over his air filtration system. He also observes the Dumond Chemical's patented, environmentally safe Peel Away paint removal system.
