The Demand for Insulation-A Study in the Household Demand for Conservation

J. Daniel Khazzoom

Year: 1987
Volume: Volume 8
Number: Number 3
DOI: 10.5547/ISSN0195-6574-EJ-Vol8-No3-4
View Abstract

This paper presents my effort to provide the means of estimating a major ingredient of the demand for conservation-namely, home insulation. A detailed account of the effort and its motivation can be found in Khazzoom (1984, 1986a). The demand relationships of this model provide one block (out of three) in a jointly determined system of demand relationships: demand for electricity, demand for insulation, and demand for efficient appliances. The study is pitched toward the service-area level. I estimated a model of the household demand for insulation in the Sacramento Municipal Utility District's (SMUD's) service area, which has a population of over 760,000.

Nonresponse in Residential Energy Surveys: Systematic Patterns and Implications for End-Use Models

Paul M. Ong, Suzanne Holt, Lisa A. Skumatz, and Richard S. Barnes

Year: 1988
Volume: Volume 9
Number: Number 2
DOI: 10.5547/ISSN0195-6574-EJ-Vol9-No2-9
View Abstract

Surveys-one of the most widely used tools for collecting information relevant to studying residential energy consumption-are both a boon and a bane to researchers. The data can be used to calculate appliance and insulation saturations and, when combined with billing information, used to model household demand for energy. Unfortunately, most of these surveys, commonly known as residential appliance saturation surveys, have an inherent problem associated with incomplete responses. This particularly applies to questions regarding energy-related characteristics of the housing units, such as whether or not the units are insulated.

Cold Hands, Warm Hearth? Climate, Net Takeback, and Household Comfort

Peter M. Schwarz and Thomas N. Taylor

Year: 1995
Volume: Volume16
Number: Number 1
DOI: 10.5547/ISSN0195-6574-EJ-Vol16-No1-3
View Abstract

Insulation reduces marginal heating cost and may lead to a takeback effect of higher wintertime thermostat settings, with a consequent dilution of energy savings. Alternatively, additional insulation could permit a lower thermostat setting by reducing drafts and radiation while increasing moisture retention, thereby enhancing comfort. This paper evaluates thermostat net takeback, the difference between takeback and enhanced comfort. Evidence supports the existence of both effects, with net takeback at the low end of literature estimates. Net thermostat takeback is on the order of 0.05 degrees F, leading to an energy takeback that ranges from 1-3% of potential energy savings, depending on climate and house size. Other significant determinants of thermostat are heating energy price and the presence of elderly or young occupants.

Does Retrofitted Insulation Reduce Household Energy Use? Theory and Practice

Arthur Grimes, Nicholas Preval, Chris Young, Richard Arnold, Tim Denne, Philippa Howden-Chapman, and Lucy Telfar-Barnard

Year: 2016
Volume: Volume 37
Number: Number 4
DOI: 10.5547/01956574.37.4.agri
View Abstract

We analyze the household energy use impacts of a large-scale, universally available, subsidized retrofit insulation and clean heat scheme. Theory shows that the energy-saving effects of such schemes are ambiguous. Our difference-in-difference model of energy impacts resulting from each of insulation and clean heat treatment uses a sample of more than 12,000 treated houses. Retrofitted insulation treatment under the Warm Up New Zealand: Heat Smart program resulted in a statistically significant reduction in metered household energy consumption of almost 2%. Clean heat (heat pump) treatment resulted in increased electricity use but little change in total metered energy use other than at warmer temperatures, when heat pumps may have been used as air conditioners. Actual energy savings from insulation are approximately one-third of the modeled energy savings predicted by an engineering model.
