Building owners are caught between two powerful forces--the need to lower energy costs and the need to meet or exceed outdoor air ventilation regulations for occupant health and comfort. Large amounts of energy are wasted each day from commercial, institutional, and government building sites as heating, ventilation, and air conditioning (HVAC)…

Air filters perform an important function in commercial and institutional facilities. Because indoor air typically is two to five times more polluted than outdoor air, air filters are needed to remove respirable particles such as microorganisms, dust and allergens from the breathing air. In fact, air filters provide the primary defense for…

Displacement ventilation (DV) units use the natural buoyancy of warm air to improve ventilation and comfort. Although relatively new to the United States, DV has been used in Scandinavian countries since the 1970s. Two types of DV can be used in a classroom: (1) Conventional displacement ventilation (CDV) units which are situated on an interior…

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…

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…

A new high school in Stillwater, Minnesota, was completed in June 1993 with the objectives of creating a safe indoor environment, minimizing health risks to construction workers, and avoiding a negative impact on the environment. Lists the guidelines used to evaluate products and methods. Displays the findings of five school systems regarding the…

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…

The American Institute of Architects National Committee on Architecture for Education presents this guide which addresses methods of energy conservation in school buildings with simple design, construction, and equipment-control technology so that trained and creative people can take over functions normally done by machinery and automated…

The principal publications the Arkansas Energy Office offers to the public on energy conservation, solar energy, and renewable energy resources are presented in this one volume for convenient reference. These publications are organized under the following headings: (1) retrofits for conservation; (2) solar energy; (3) active solar energy; (4)…

Building design and construction that helps deliver both superior air quality and occupant thermal comfort, while minimizing energy consumption, are examined. The paper explores an integrated building systems approach that combines the principles of "directed air flow control" and "demand controlled ventilation" where ventilation is effectively…

A Minneapolis, Minnesota, elementary school under construction has been uniquely designed to incorporate improved air quality as a key component in boosting student health and performance. Lists common-sense adjustments existing schools can make to improve the quality of their interior air. (MLF)

A new elementary school in New Hampshire uses innovative European ventilation technology to ensure excellent air quality. Combined with high-efficiency lighting, the system should reduce energy consumption by 10 to 20%, compared with a traditional facility. (MLF)

Scores of millions of dollars are spent annually in the United States for new school buildings. With this large. expenditure has come a general desire that schoolhouses shall be usable, healthful, comfortable, and beautiful. Educators and architects have united in devising plans for school buildings. This bureau has published a valuable bulletin…

A study of the energy usage for 20 St. Cloud (Minnesota) district buildings was completed by a firm of consulting engineers. For each building, the study established a Total Energy Index (TEI) composed of the fuel, electricity, and water consumed during the base line year, fiscal year 1977-78. In addition, the blueprints and any proposed…

The Department of Education has undertaken an ambitious effort to develop statewide career and technical education skill standards. The standards in this document are for Heating, Ventilation, Air Conditioning and Refrigeration (HVAC&R) programs and are designed to clearly state what the student should know and be able to do upon completion of…
