MWX90: Minnesota Low Income Weatherization Procedure for the 1990's
In this manual, we define the procedures and guidelines for providing cost-effective weatherization in a heating-dominated climate.
Seasonal Efficiency and Off-Cycle Flue Loss Measurements of Two Boilers
In situ input/output measurements were performed on a hot water and a steam boiler, both of which are used in apartment building central heating systems.
Field Validation of Diagnostic Techniques for Estimating Boiler Part-Load Efficiency
A theoretical basis for various short-term boiler diagnostic test techniques--heat-up/cool-down; stop-loss; and time-to-make-steam--is presented along with the results of applying, these techniques in situ to three boilers to estimate the off-cycle energy loss rates and part-load efficiencies.
Analysis of Error in Using Simplified Models to Approximate the Heating or Cooling Output of Fan Coil Units for Energy Cost Allocation Purposes
This paper assesses how well various simple linear models approximate the true relative heating or cooling output of fan coil units under various ranges of application conditions. It further assesses the improvement possible in using non-linear models that follow the known form of the heat transfer relationship.
Field Measurements of Off-Cycle Losses and Seasonal Efficiency for Major Classes of Multifamily Boilers
For multifamily buildings, space heating improvements offer one of the best potentials for saving energy. However, the energy savings and cost-effectiveness of space heating retrofits and boiler replacements depend critically on the efficiency of the existing boiler.
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.
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.
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.
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.
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.
