Family Housing Insulation Energy Conservation Opportunity (ECO) Study, Ft.Belvoir, Virginia. Revised

摘要

Six (6) family housing groups on the installation of Ft. Belvoir, including bothdetached and duplex type housing units, have been selected as prototypes' for this limited scope energy study. In general, these housing units are in good condition, but are not energy efficient by today's standard. In order to meet the requirements of Executive Order 12902 (March 8, 1994): Energy Efficiency and Water Conservation at Federal Facilities, various types of passive and active energy conservation measures were selected for detailed study to determine their viability based on life cycle cost analysis. 'Active' measures include those which require the installation of new or replacement electrical/mechanical equipment which would improve the energy performance of the operation of housing units as a whole, such as high efficiency lighting fixtures, programmable thermostats and whole house fans, etc. 'Passive' measures include those which improve the thermal characteristics of the structure, such as addition of insulation to exterior walls/attic/crawl space, addition of storm windows or replacement of single pane with double pane type, etc. The intent of the study is to establish the current level of energy consumption for each of the prototype housing groups (baselines'), and to recommend energy conserving options, known as Energy Conservation Opportunities' (ECOs), which demonstrate through heating and cooling load calculations and life cycle cost simulations to be economically viable. The ECOs which meet the criteria of Energy Conservation Investment Program (ECIP) are then packaged for funding requisition purposes, and recommendations for these prototypes may be applied to other housing groups on base with similar characteristics and projected performance.
