Heating Cost Allocation: Centrally Heated Rental Housing, Energy Conservation Potential and Standards Issues
Economic analysis showed that the owners could achieve a one year payback while increasing tenants’ total average costs by only five dollars per month. Owners reported generally positive tenant reactions and no long term increase in turnover or vacancy.
Characterization of 5 to 9 Unit Residential Buildings in Minneapolis
A study done by the Minneapolis Energy Office (MEO) characterizing 5 to 9 unit residential buildings in Minneapolis was conducted as one segment of an overall multifamily baseline study.
Achieving Even Space Heating in Single Pipe Steam Buildings
The Minneapolis Energy Office has been involved with research and testing of steam heated apartment buildings for four years. This paper summarizes and reports the results of our testing and the conclusions of our work to date.
Measured vs Predicted Savings from Single Retrofits
Energy savings from single retrofits in one-and two-unit homes have been investigated in order to provide more reliable estimates to homeowners who are considering a conservation investment.
Data Quality Considerations in Using the Prism Program
We have found PRISM to be quite user-friendly and to normally produce realistic and robust estimates, but our testing and production experience also shows that its results can be quite erroneous if insufficient attention is given to several crucial data quality issues.
Calibration of an Outdoor Reset in a Steel Fire Tube Boiler with a 3-way Mixing Valve
The Minneapolis Energy Office installed outdoor resets and 3-way mixing valves in three hot water multi-zone buildings with steel fire tube boilers in order to determine the cost and savings of this retrofit.
Single Pipe Steam Air Venting
The Minneapolis Energy Office conducted experiments both in the laboratory and in the field to investigate the properties of single pipe steam air venting.
Superinsulation – Questions of Cost Effectiveness
The energy use and economics of a group of superinsulated and conventional houses were studied. Conventional construction was found to use considerably less energy than is generally assumed. The economic advantage of superinsulation is therefore less.
Measured Energy Savings from Outdoor Resets in Modern, Hydonically Heated Apartment Buildings
Since 1982 the Minneapolis Energy Office and Minnegasco have been testing outdoor reset and cutout controls in modern, hydronically heated apartment buildings.
Preliminary Evaluation of the Neighborhood Energy Workshop Program
The Neighborhood Energy Workshop (N.E.W.) Program is a comprehensive, neighborhood oriented energy conservation program co-sponsored by the City of Minneapolis and Minnegasco, a natural gas utility.
