Measured Savings from Integral Flue Dampers and Thermal Vent Dampers on Domestic Hot Water Heaters in Multifamily Buildings

This research was undertaken to further investigate the benefits of using an integral flue damper versus a thermal vent damper on commercial tank-type water heaters.

Technical Report

Measured Savings from High Efficiency Replacement Tank-Type Domestic Hot Water Heaters in Multifamily Buildings

In order to measure savings and assess performance of the "best available technology" for this application, high efficiency condensing tank-type water heaters were installed in parallel with existing conventional tank-type DHW heaters in two apartment buildings.

Technical Report

Measured Savings from Domestic Hot Water Control Strategies in Multifamily Buildings with Recirculation Loops

To investigate the strategy of reducing system temperatures during periods of low demand, time-based and demand-based temperature controls were installed in three apartment buildings.

Commercial Gas Space Heating Equipment: Opportunities to Increase Energy Efficiency

This study was undertaken to identify cost effective energy efficiency technologies and strategies for gas-fired space heating of small commercial buildings (less than 50,000 sq. ft.); to identify potential approaches for increasing market penetration of these technologies and strategies; and to identify promising technologies and strategies which require further verification of energy savings by field and/or laboratory testing.

Technical Report

Retrofit Savings for Dual Integrated Appliances in Small Commercial and Multifamily Buildings

DIA systems have had substantial market penetration in the warmer climates of the mid-atlantic states, but there are appropriate selected markets in colder climates as well. The primary goal of this study is to assess the applicability of DIA systems in small commercial and multi-family buildings in a cold climate.

Technical Report

Commercial Gas Cooking Equipment: Current Status and Future Directions

A number of other promising technologies have been developed and tested in the laboratory (eg; pulse combustion fryers and griddles, vent dampers) but have not been manufactured or else were marketed for a while and then withdrawn, apparently due to a lack of interest in the marketplace.

Technical Report

Radon Mitigation Energy Cost Penalty Research Project

This study performed an investigation of the energy penalty of active soil depressurization radon mitigation systems.
