In the past eight years, the design standards of classrooms have improved significantly. This movement was instigated by the introduction of the classroom acoustics standard in 2002 from the American National Standards Institute (ANSI), in collaboration with the Acoustical Society of America. The standard, formally known as ANSI S12.60, has become…

Discusses factors that affect energy consumption and describes a variety of heat recovery devices that can be applied to many new or existing ventilation systems. (Author/MF)

Modified and controlled relative humidity in buildings for certain occupancies is discussed. New criteria are used in determining the needs, desirability and problems associated with humidities in a building. Severe winter climate requires that special attention be given to the problems associated with increased indoor humidities during cold…

Discusses key factors to be considered by local educational authorities in creating a healthful -- and consequently constructive -- environment in the school building for students, teachers, and administrators. Focuses on ventilation, air cleaning, and humidification. (EA)

This paper describes a study that developed innovations that would enable modular builders to improve the energy performance of their classrooms without increasing their first cost. The Modern Building Systems' classroom building conforms to the stringent Oregon and Washington energy codes, and, at $18 per square foot, it is at the low end of the…

Quality, not intensity, is the keystone to good library lighting. The single most important problem in lighting is glare caused by extremely intense centers of light. Multiple interfiling of light rays is a factor required in library lighting. A fixture that diffuses light well is basic when light emerges from the fixture. It scatters widely,…

Contains a selected and annotated listing of source material concerning the thermal environment in school facilities. It is directed toward the school planner, architect, or administrator concerned with developing a more functional classroom environment. Topical coverage includes--(1) The Thermal Environment and Learning, (2) Physiological Factors…

A multitude of design strategies are available to achieve energy-efficient windows. Opportunities for improving window performance fall into six groups: site, exterior appendages, frame, glazing, interior accessories, and building interior. Design strategies within these groups can improve one or more of the six energy functions of windows: solar…

Much of the innovative work in the design and application of heating, ventilating, and air conditioning (HVAC) systems is concentrated on improving the cost effectiveness of such systems through optimizing energy use. One approach to the problem is to reduce a building's HVAC energy demands by designing it for lower heat gains and losses in the…

The testing plans, procedures, and results of an experiment are revealed concerning the thermal performance and variable factors of unvented double windows, their heat transmission and inner surface temperature. Data are given to help improve the design and development of standards for the thermal performance of windows. Building humidity, window…

Public building air conditioning systems, which use constant and varying heat and cooling loads, are compared and investigated. Experiments indicated that constant temperature controls based on outside air temperature alone were inefficient. Ventilating a building with outside air and the methods of doing so are cited as being the most economical…

THIS IS A REPORT OF A FIRST PILOT STUDY WHICH PRECEDES A SERIES OF STUDIES BEING CONDUCTED BY THE IOWA CENTER FOR RESEARCH IN SCHOOL ADMINISTRATION AND LENNOX INDUSTRIES INC., MARSHALLTOWN, IOWA. IT IS A DIGEST OF A THESIS BY DR. CHARLES PECCOLO WHO SERVED AS RESEARCHER ON THIS FIRST STUDY. THE STUDY AIMED AT MEASURING THE EFFECTS OF THERMAL…
