The long-term performance of any exterior building enclosure assembly is directly related to the level of planning implemented during the initial phases of the design process. It requires the combined efforts of the owner, building enclosure commissioning provider (BECxP), design team, and contractors.
The open-office concept has become increasingly popular in today’s workplace. There are many advantages to this approach, including increased opportunities for collaboration, greater space efficiency, and potential for an interactive energy that appeals to many current employees as well as prospective talent.
Plastic foams for thermal insulation have been available for more than 70 years. Extruded polystyrene (XPS) was introduced in 1943, followed by expanded polystyrene (EPS) in 1950, and polyisocyanurate (polyiso) in 1954.
Experts believe as many as one-third of all school students miss up to 33 percent of the oral communication that occurs in the classroom. (M. Nixon’s 2002 article, “Acoustical Standards Begin to Reverberate: Controlling Noise within School Facilities,” was posted on the web at School Construction News Online).
Fenestration—such as windows, curtain walls, window walls, sloped glazing, storefronts, and doors—affects building energy use through four basic mechanisms: thermal heat transfer, solar heat gain, visible transmittance, and air leakage. Product designers, architects, and specifiers must reconcile the interplay of these factors to arrive at, or verify, optimal thermal performance.
