This paper reviews the development of performance indices for fabric thermal storage from the original BRE office research data to the two mixed mode design options currently available, each having different design priorities, namely naturally ventilated or mechanically ventilated. Naturally ventilated mixed mode designs appear to be less suitable for UK locations and also appear to have significantly greater annual energy consumption. In addition to the comparison of energy consumption criteria, the paper also reviews recent Scandinavian indoor climate classifications.

This paper describes the objectives and research methodology of a 30-month research project carried out under the European JOULE programme with the involvement of seven countries with cold or temperate climate. The project aims to contribute to reducing energy consumption and consequent C02 emission in buildings by overcoming barriers preventing the wider uptake of technologies for natural ventilation (NV) and low-energy cooling and encouraging and accelerating environmentally-friendly natural ventilation and 'smart' controls as a main design option.

This paper examines key issues involved in evaluating benefits of tree planting programs from the perspective of electric utilities, as well as from a wider perspective of public and private entities that may benefit from such programs. The nation's largest shade tree program, sponsored by the Sacramento Municipal Utility District (SMUD) in collaboration with the Sacramento Tree Foundation (STF), is used as a case study.

This paper compares energy and environmental awareness in two small towns in Sweden and Minnesota over time. In the early 1980s, Minnesotans were more anxious and exerted greater conservation efforts than the Swedes, but both are now bored with energy issues. They focus instead on environment-namely, recycling. Saving money continues to dominate decisions, but time is gaining priority in tradeoffs of energy, money, and time. Environmental concern is usually sacrificed to economics. Certain culturally-valued behaviors override both more conserving alternatives and economic considerations.

Comparative energy information is one method energy policymakers have employed to motivate consumers to reduce their energy use. The US appliance labeling program, for example, has used graphical displays to illustrate the differences in energy consumption among home appliances. Little is known, however, about how consumers interpret various graphical displays and/or how they use the information. Additionally, subtleties in the accuracy with which these graphical displays convey the underlying data have yet to be addressed in the research literature.

How do tenants of public housing respond to retrofits to improve their comfort and energy use during the cooling season? In contrast to retrofits to improve heating or lighting, cooling retrofits have been little studied, despite extensive programs by utilities and housing authorities to reduce this end use. A local utility and a housing authority have been retrofitting their buildings with evaporative coolers, ground-source heatpumps and other cooling measures.

Since the combustion of fossil fuels is the leading causative factor in global climate change, the "Westernmodel'' of adopting energy-using technologies and using ever-greater amounts of energy will have important consequences for the future of human life on the planet if it is transferred on a wholesale basis to the developing world. It is thus important to Uy to understand, in the context of global development.

This authors draw upon 16 years of evaluation experience in conducting energy service marketing evaluations and market assessment research in the commercial and small industrial sectors to present real-life experiences and results of marketing efforts for energy services. The paper covers the use of mass and targeted media, community groups, trade allies, social groups and networks, demonstrations, one-on-one appeals and other methods to market energy services.

Increased building indoor air quality (IAQ) complaints due to reduced outdoor air ventilation rates led to ASHRAE Standard 62-1989. Even though the stipulated total outdoor ventilation flow rate may be drawn into the HV AC system, thermal imbalances in the various zones of the building can lead to certain zones being starved of the specified ventilation flow rate thereby creating localized IAQ problems.
