Abstract

Millions of single-family masonry (block) houses with slab foundations exist in the southern United States. In fact, approximately 50% of Florida`s six million residences are of concrete block construction. The block walls in these homes are usually uninsulated, and the technology for retrofitting wall insulation is not well developed. Two field tests were performed--one near Phoenix, Arizona and one in Cocoa, Florida--to measure the air-conditioning energy savings and demand reduction impact of applying an exterior insulation and finish system (EEFS) to the exterior of the block wall, and gain practical experience with retrofit application techniques and costs. One field test used a {open_quotes}site-fabricated{close_quotes} insulation system, while the other field test used a commercially available system. The field tests measured a savings of 9% in Arizona and less savings in Florida, and emphasized the impact indoor temperature settings have on cooling energy savings: exterior wall insulation on block homes will produce energy savings in Florida houses only if a low cooling thermostat setting is desirable. The field tests also highlighted an improved comfort benefit from the retrofit - namely, elimination of overheating in rooms with south and west exposures. The DOE-2. ID program was used to analyze the energy savings (air-conditioningmore »« less

ID program was used to analyze the energy savings (air-conditioning and heating) and electric demand impact of applying an EIFS. Air-conditioning energy savings were estimated to be in the range of 8% to 10% in many southern U.S. regions. A 12% savings was predicted for Phoenix, Arizona and a savings of 1% to 4% was predicted for seacoast regions, particularly in Florida. These predictions were in good agreement with the measured values. Peak hour cooling energy savings were predicted to be more uniform throughout the country, generally in the range of %8 to %12.},

Air-conditioning electricity savings and demand reductions from exterior masonry wall insulation applied to Arizona residences

Technical Report Ternes, M; Wilkes, K

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. 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 masonrymore »« less

Cooling energy performance and installation of a retrofitted exterior insulation and finish system on masonry residences in the southwestern United States

Conference Ternes, M; Wilkes, K; McLain, H

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.
