Three phases leading to the automation of the mechanical building systems on the Harvard campus are described. The systems allow a single operator to monitor and control all the mechanical systems, plus fire, flood, and security alarms, for all buildings in a large area of the campus. (JT)

Discusses methods of ensuring that technological forces are harnessed for the common good and that mere technological change is not pawned off on us as technological progress." Argues that many problems have arisen because there was no group in charge" of technology. (AL)

Discusses the new classroom acoustics standard, ANSI Standard S12.60, which specifies maximum sound level limits that are significantly lower than currently typical for classrooms. Addresses guidelines for unducted HVAC systems, ducted single-zone systems, and central VAV or multizone systems. (EV)

Provides tips on using air filtration to control indoor air quality in educational facilities, including dedicated spaces with unique air quality conditions such as in libraries, museums and archival storage areas, kitchens and dining areas, and laboratories. The control of particulate contaminants, gaseous contaminants, and moisture buildup are…

Explores roofing options that can help control energy costs through use of highly reflective roofing materials. Additionally discussed is the "Urban Heat Island" phenomenon created when several super-heated buildings are clustered in a small area. (GR)

Explains how Cornell University is using lake water to cool 40 percent of the space in its central campus. Payback cost estimates and design and engineering issues are examined. (GR)

It's a cool field where the job prospects are hot. That's the message that a lot of trade associations and education organizations are trying to get out about heating, ventilation, air conditioning and refrigeration (HVACR), and they have the statistics to back them up. The Occupational Outlook Handbook from the Bureau of Labor Statistics says…

Secondary vocational-technical education programs in Mississippi are faced with many challenges resulting from sweeping educational reforms at the national and state levels. Schools and teachers are increasingly being held accountable for providing true learning activities to every student in the classroom. This accountability is measured through…

Dedicated teachers and an innovation program make an Illinois summer program fun--while central air conditioning makes it environmentally comfortable. (Author)

THIS IS A FINAL REPORT OF A STUDY OVER A FOURTEEN MONTH PERIOD FROM APRIL, 1959 TO JUNE, 1960 OF HEATING AND COOLING TWO SCHOOL CLASSROOMS AND A COMPARISON WITH A THIRD CLASSROOM IN WHICH THERE WAS HEATING AND FRESH AIR CIRCULATION ONLY. ALL THREE ROOMS HAD AN AIR-FLOW DISTRIBUTION SYSTEM. A TYPHOON HEAT PUMP PROVIDED HEATING AND COOLING IN ONE…

Presents planning considerations in selecting proper temperature control systems. Various aspects are discussed including--(1) adequate environmental control, (2) adequate control area, (3) control system design, (4) operators rate their systems, (5) type of control components, (6) basic control system, (7) automatic control systems, and (8)…

The superior insulating characteristics of an exterior wall system has enabled a Massachusetts school district to realize a savings on electric heating, ventilating, and air-conditioning systems. (Author/MLF)

This document describes a 1998 commissioning statute passed by the Minnesota legislature requiring that mechanical HVAC systems undergo an inspection process to uncover and rectify problems before or shortly after a school building is occupied. The document presents the statute, describes the commissioning/system-inspection process and optional…

This second article in a series on energy conservation sets up an overall attack on energy waste in the school environment. The campaign begins with proper operation and maintenance procedures. (See EA 005 433 and EA 504 535 for related information.) (Author)
