Reports on an investigation of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 62-1999 on outdoor ventilation rates and space humidity levels for schools. Examined conventional cooling versus desiccant-based systems designed to control indoor humidity levels. Discusses the effectiveness of systems…

Describes a project at the Manatee Education Center in Naples, Florida, which won an ASHRAE award. Project involved the implementation of ice-storage technology in 19 schools. Compares the performance of ice-storage systems with traditional chiller designs in two other schools. Tables illustrate costs for the campuses. Addresses the maintenance…

Ivy Tech State College uses River Falls, a shopping mall, as an enormous heating, ventilation, and air conditioning laboratory. Students spend Saturdays working with full-time technicians getting invaluable training and experience. Students see the program as a professional opportunity and a direct route to jobs. (JOW)

This article summarizes the inventory findings related to nonfossil energy technologies and energy conservation. It is divided into four trade clusters that are most significantly affected: construction; heating, ventilation, and air conditioning; automotive; and power generation. (Author/CT)

Although heating, ventilation, and air conditioning (HVAC) engineering degrees are not offered, there is a serious need for specialists and consultants in this area (since most have been trained as mechanical engineers). Opportunities exist for individuals possessing a customer-oriented attitude, with knowledge in computerized controls, innovative…

Discusses how to spot indoor air quality (IAQ) problems in schools and possible actions to take to eliminate them. Highlights the types of pollutants that contribute to IAQ deterioration and the physical symptoms commonly associated with them, and suggests ways of addressing older heating, ventilation, and air conditioning systems to improve air…

Explains how commissioning can help to ensure that all components in a new heating, ventilation, and air conditioning system will work together as designed. Bowdoin College's experience with commissioning is highlighted. (GR)

Explores the steps to take to reduce the likelihood that indoor-air-quality (IAQ) problems will develop in educational facilities. Highlights sources and hazards of IAQ when renovating buildings; control strategies and the establishment of IAQ close-out criteria for all renovation projects; heating, ventilation, and air-conditioning system…

Provides tips on choosing a school heating/ventilation and air-conditioning system that meets a school's needs and budget. Discusses how to assess a school's needs and offers suggestions for making the final decision. Data tables are provided that compare various systems, including costs, maintenance, and life expectancy. (GR)

The author outlines course content, performance objectives, and student activities for a high school program for heating, ventilating, and air conditioning mechanics. (SK)

This first article in a series about cooling classrooms by ventilation explains that energy consumption for one day of refrigeration cooling is equal to energy use for 35 days of ventilation cooling. Schools using only refrigeration cooling are passing up energy savings that could be provided by ventilation cooling. (Author/MLF)

Because community libraries are becoming centers of suburban and "exurban" activity, quiet study rooms are being constructed for customers intent on concentrated study. Discusses functional (size, location, furniture) and physical (acoustic, heating, ventilation, air conditioning, lighting, electronic support) considerations of quiet…

Explains how a well-designed heating and air conditioning system with good facility maintenance can prevent most indoor air quality problems in schools. Stresses attention to issues of leak prevention and sanitation. (GR)

This second article in a series about cooling classrooms by ventilation describes the equipment available to help save energy and money. The first article appeared in the July 1981 issue. (Author/MLF)

Describes how renovation can transform a school to a state-of-the-art facility without having to work from the ground up. Examined are the planning and design phases, the outer structure upgrading, the installation of more efficient heating, ventilation, and air conditioning systems, and renovation costs. (GR)
