In energy-efficient residential construction and in large modern buildings, ventilation is not left to the vagaries of miscellaneous cracks and joints instead, controlled ventilation is provided mechanically. In such cases, engineering data may be available to indicate ventilation rates. 

Residential Construction. Owing to rising energy costs, the cost and low thermal conductivity are of prime importance in wall and ceiling insulation of residential buildings. The combination of insulation efficiency, desirable stmctural properties, ease of appHcation, abiHty to reduce air infiltration, and moisture resistance has led to use of extmded polymeric foam in residential constmction as sheathing, as perimeter and floor insulation under concrete, and as a combined plaster base and insulation for walls.

Heat losses in residential buildings occur primarily via convection from the roof ( 25-35%) followed by air leakage and walls ( 15-25% each). Adequate insulation in roof and exterior walls is therefore a significant energy-saving investment. Table 5.7 compares thermal conductivity and environmental merits of different insulation materials (Dewick and Miozzo, 2002). The insulation efficiency is typically...

In situ foaming is an another typical on-site application used mainly for insulation purposes. Since rigid PU and polyisocyanurate foams provide the most energy efficient and versatile thermal insulations, they are preferable for use in roof and wall system applications, for both residential and commercial buildings.

Variable-speed fan drives permit conditioned air distribution to be matched more closely to a building s needs. High-efficiency electric motors are used to drive the fans, saving as much as half the energy once used. Both variable-speed and high- efficiency motors are being applied even in residential air conditioning systems.
