Efficient Lighting 101
Advances in lighting technologies have huge potential to save energy - if we match them to the proper application.
Measured Residential Hot Water End Use
High-resolution data on draw volume, length, flow rate, and spacing both overall and by hot water end use; based on data collected in ten homes in the Minneapolis/St. Paul metro area.
Energy Efficient Cities: Using a Community-Based Approach to Achieve Greater Results in Comprehensive, Whole-House Energy-Efficiency Programs
The Energy Efficient Cities project was developed to demonstrate the delivery of innovative residential energy-efficiency programs to reduce energy use and environmental impact in at least 6,000 homes through a community-wide partnership approach.
Application of a Linear Input/Output Model to Tankless Water Heaters
This study evaluates the applicability of a linear input/output model to gas-fired, tankless water heaters. The model can be used to reproduce performance metrics, such as the energy factor, and can be used to evaluate the impacts of alternative draw patterns and conditions.
Actual Savings and Performance of Natural Gas Instantaneous Water Heaters
To gain a better understanding of in situ performance, 24 natural gas water heaters were installed in ten Minnesota homes, then extensively monitored and tested under an alternating mode test procedure for 15 months.
Change in Indoor Particle Levels After a Smoking Ban in Minnesota Bars and Restaurants
The primary objective of this study was to provide detailed time-of-day and day-of-week secondhand smoke–exposure data for representative bars and restaurants in Minnesota.
Actual Savings and Performance of Natural Gas Tankless Water Heaters
This project field tested efficiency improvements and energy savings achieved by replacing standard hot water heaters with tankless models.
Secondhand Smoke Transfer and Reductions by Air Sealing and Ventilation in Multiunit Buildings: PFT and Nicotine Verification
This study was undertaken to quantify bulk air transfer between units and document transfer of Secondhand Smoke species before and after treatments that sealed boundaries between units and provided a minimum amount of continuous exhaust ventilation of each unit.
Cost-Effective Boiler System Retrofits
The cost of energy is a significant portion of the operating expenses for any commercial building. Yet these same energy expenses are often the single largest controllable cost of operations.
