Thermal Comfort and Strategies for Energy Conservation

Human response to the thermal environment depends on seven variables: (1) air temperature, (2) relative humidity, (3) mean radiant temperature (temperature from surfaces such as windows), (4) air velocity, (5) clothing, (6) physical activity, and (7) time. After discussing major studies in thermal comfort which served as the basis for the comfort standard, and outlining the comfort standard itself, these seven factors are discussed individually in terms of ways in which they can be modified to conserve energy. Special topics include the Federal Emergency Building Temperature Restriction Plan (65°F in winter, 78°F in summer), night set‐back, accidential hypothermia in the elderly, seasonal effects and interior decor.
