Description/Abstract The final report presents the results of research on cost-effective energy efficiency improvements for existing low to moderate income multifamily buildings heated by gas-fired single pipe steam systems.^Analyzed measures include indoor thermostats, main line vents, radiator vents, boiler derating, vent damper.^Eleven buildings were instrumented and monitored over a three-year period to document the effect of the test measures on boiler gas usage, tenant gas and electricity usage, and indoor temperatures.^The results indicate that proper specification and installation of thermostats, main line and radiator vent treatments and derating can result in 20% savings in annual space heating costs for a capital investment of under $200 per unit and a payback of under three years.^They are applicable to almost all single-pipe steam heating buildings.^They also can improve tenant comfort and reduce the tenant-borne expense of supplemental heating.^Updated procedures are included for specifying and implementing the thermostat and vent treatments and for measuring their performance and boiler seasonal efficiency.
