Procedures were developed and tested to conduct a quick and reliable evaluation of weatherization program energy savings using heating system nm-time loggers. This project performed: (1) a statistical analysis to determine the measurements and assessment constraints on short-term nm-time monitoring, and (2) a field test of the data collection procedures with three weatherization providers.

There are many hurdles in the road to widespread adoption of energy-efficient heating and cooling (HVAC) equipment in homes. These hurdles include increased first cost, lack of sufficient financing, historic lack of aggressive marketing by HVAC equipment dealers, and lack of consumer awareness. This paper reports on the design and progress of the ENERGY STAR market-based approach to overcome these hurdles to encourage the widespread manufacture and purchase of highly efficient heating and cooling equipment.

Residential new construction and renovation programs, home energy rating systems programs and energy efficient mortgage instruments are some of the many ways that local energy utilities and other state or federal agencies attempt to increase the supply and demand of energy efficient housing.

Thermal distribution systems represent the most promising opportunities for cost-effective energy savings in residential new construction. This paper describes the results of an unusual but on-going collaboration between the building industry, the environmental community, the research community, and the regulators to develop cost-effective, implementable procedures for improved heating, ventilating and air conditioning (HV AC) duct system design, fabrication, and installation

A five-year initiative between the U.S. Department of Energy (DOE) and the U.S. Department of Housing and Urban Development (HUD) demonstrated the feasibility of improving the energy efficiency of publicly assisted housing. Twenty-seven projects and activities undertaken during 1990-95 involved research and field demonstrations, institutional and administrative changes to HUD policies and procedures, innovative financing and leveraging of federal dollars with non-federal money, and education, training, and technical assistance.

In an effort to optimize the energy performance of existing single-family housing, the Advanced Retrofit pilot program was sponsored by Massachusetts Electric and administered by Conservation Services Group. The intent of the program was to advance the direction of energy conservation by achieving the highest energy savings possible, by combining field experience with innovative technologies in electrically heated homes. Cost-effectiveness was not a constraint in this pilot program.

As required by the National Appliance Energy Conservation Act (NAECA), minimum energy efficiency standards ranging from 8.0 to 9.0 EER went into effect for window-type room air conditioners on January 1, 1990. But by incorporating commonly used technologies such as high-efficiency rotary compressors, grooved refrigerant tubing, slit-type fins, subcoolers, and permanent split capacitor fan motors, 10.0 EER efficiency levels can be achieved for the most popular classes of room air conditioners without having to increase chassis size.

Research over the past five years has indicated that a significant majority of the cost of residential retrofit duct sealing is in the labor required to find and seal those leaks. This paper describes the results of a field investigation of the performance and practicality of sealing residential duct leaks from the inside by means of a technique based upon injecting a fine aerosol spray into the duct system. The field results presented are from 4 7 houses located in Florida.

A detailed evaluation methodology, originally developed for PG&E's Act2 Project, was used to design cost-effective packages of energy efficiency measures (EEM's) for two residential sites in the Coachella Valley desert region of Southern California Design of the packages was based on "mature market" cost assumptions, which assume that the EEM has achieved volume production and widespread application in the marketplace. EEM packages were installed at the two sites (one new construction and one retrofit) and monitored for nine months during 1995.
