Reports that a water mist fire suppression system achieves better results when it is cycled on and off, than it does with a steady discharge of mist. In some cases cycled discharge reduces both extinguishment times and water requirements.

"If I can't control the lighting in my office, I'm unhappy and unproductive." It's easy to agree with such a statement. But although lighting controls can let you tailor lighting to tasks and to save energy, recentresearch at the National Research Council (NRC) suggests that having control doesn't have a simple, direct, or immediate effect on worker satisfaction or performance. Longer-term effects remain unknown.

Reviews the development of thermal insulation standards in Canada, and the role of the new Thermal Insulation Systems Standards and Quality Consortium (TISSQC).

Discusses, A Building Envelope Lifecycle Cost Assessment Model, is a consortium made of the IRC, PWGSC and other owners of large numbers of roofs.

Describes FiRECAM, a computer program which allows evaluation of possible trade-offs in fire protection subsystems, such as number of egress paths vs. sprinklers and fire alarms, without making the occupants less safe.

When the National Research Council established the Division of Building Research (DBR) in 1947, it was to do more than address the general need for building research. Two special tasks were assigned to the new division: to provide technical support for the revision of the National Building Code, and to provide technical support to the national housing agency know then as Central Mortgage and Housing Corporation.

People in fires need fast and accurate information about what is happening where, and what they should do. The challenge to the controls industry is to design and manufacture systems to get information to people that is appropriate and explicit in the instructions given. This paper discusses the merits of an automated system using pre-recorded messages and a manual system that allows emergency personnel to speak to building occupants through a public address system.

An increasing number of adult patients are becoming more aware of their orthodontic needs, and more willing to pursue treatment. This article identifies some of the major differences in the orthodontic treatment of children and adults, and summarizes important aspects of adjunctive orthodontic treatment for adults that may facilitate other dental treatment. In addition, a number of clinical scenarios in which adjunctive orthodontics may enhance the provision of restorative treatment in adult patients are identified.
