Supermarket Refrigeration Market Assessment

The overall goal of this project was to assist Northern States Power Company in updating and expanding their C&I refrigeration rebate program by identifying technologies which have good potential to reduce demand and/or energy use, but are not currently widely implemented.

Technical Report

Improving Cooling Equipment for the Small Commercial Buildings Market

This report examines the importance of various types and sizes of cooling equipment in the small commercial market, the availability and incremental cost of efficient commercial cooling equipment, and recent developments in codes, standards and utility demand side management programs for commercial cooling.

Technical Report

Lighting Efficiency in New Small Commercial Construction in Minnesota

The study looked at the number of buildings that actually complied with the "1989" and "1993" Code of Federal Regulations requirements, and the incremental costs and savings associated with installing state-of-the-art lighting equipment.

Technical Report

Transferring Effective Multifamily Energy Programs to Communities in Greater Minnesota

The purpose of the Multifamily Technology Transfer Project was to ensure implementation of proven energy efficiency improvements in multifamily buildings in greater Minnesota.

Technical Report

An Evaluation of Energy Program Needs For Minnesota Non Profit Organizations

The McKnight Foundation retained the Center for Energy and the Urban Environment (CEUE) to survey their recent grant recipients about their level of familiarity and concern regarding energy efficiency issues and about any efficiency measures or programs they had already implemented or were considering implementing.

Technical Report

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.

Technical Report

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.
