Tracking Aggregate Gas Use in Minneapolis, Minnesota

Aggregate energy consumption data is a valuable resource for energy researchers, regulators, and utilities alike. Our office has used it for a number of years to track historic use trends, to periodically recalibrate our perceptions of what constitutes "typical" use, and as a pseudo-control in program evaluations for which a true matched control was not feasible within our time and budget constraints.

Technical Report

Comparative Energy Performance of Domestic Hot Water Systems in Multifamily Buildings

The overall efficiencies of four types of central domestic hot water (DHW) systems used in multifamily buildings were determined, along with the savings associated with converting to more efficient systems. Commercial tank heaters with integral flue dampers (IFD) were compared to tank heaters without IFDs in three buildings, and a high efficiency, low-mass, front end boiler (FEB) was compared to a space heating boiler also heating DHW in a single building.

Field Measurement of Multifamily Boiler Losses

Space heating offers the best potential for retrofits in this sector for several reasons.

Technical Report

Stack Flow and Loss Measurements of a Commercial Tank Water Heater

The purpose of this study is to better understand the stack losses of a commercial tank water heater. The measurements will be used to help interpret an ongoing study of the heater energy use and domestic hot water demand and estimates of standby losses.

Support of the Joint Foundation Insulation Study Conducted by Robinson Technical Services for Oak Ridge National Laboratory

MEO oversaw ten of the installations through its normal Operation Insulation program activities. This included the program audit and bid specifications, on-site management, inspection and quality control, program administration, financing, and loan processing. Retrofit costs were paid by the homeowners.
