Cooling energy performance and installation of a retrofitted exterior insulation and finish system on masonry residences in the southwestern United States
A field test involving eight single-family houses was performed during the summer of 1991 in Scottsdale, Arizona to evaluate the potential of reducing air-conditioning electricity consumption and demand by insulating their exterior masonry walls using a site-fabricated (non-commercially available) insulation and finish system. The exterior insulation system developed for the field test was easily performed and should result in a durable installation. Total per house costs to perform the installations ranged from $3610 to $4550. The average annual savings was estimated to be 491 kWh, or 9% of pre-retrofit consumption. Peak demands without and with insulation on the hottest day of an average weather year for Phoenix were estimated to be 4.26 and 3.61 kill, for a demand reduction of 0.65 kill (15%). We conclude that exterior masonry wall insulation offers the greatest potential for air-conditioning electricity savings and peak demand reductions in hot, dry climates similar to that of Phoenix. Retrofit economics need to be thoroughly examined from societal, utility, and consumer perspectives and must consider other benefits such as space-heating energy savings and improved house value.
