Assessment of Risk for Asthma Initiation and Cancer and Heart Disease Deaths among Patrons and Servers due to Secondhand Smoke Exposure in Restaurants and Bars
Lifetime excess risk of cancer death, ischaemic heart disease death, and asthma initiation among non-smoking restaurant and bar servers and patrons in Minnesota and the US were estimated using weighted field measurements of SHS constituents in Minnesota, existing data on tobacco use, and multiple dose-response models.
Secondhand Smoke Exposure in the Nonsmoking Section: How Much Protection?
Secondhand smoke exposure continues to be a problem in bars and restaurants where smoking is permitted. This study measures the relative SHS exposure reduction in nonsmoking sections of establishments that allow some smoking.
Retrofitting Combined Space and Water Heating Systems: Laboratory Tests
The NorthernSTAR DIA laboratory was created to identify proper system components, designs, operating parameters, and installation procedures to assure high efficiency of field installed systems.
Tankless Water Heaters: Do They Really Save Energy?
The in situ efficiency of the storage water heaters was nearly 20% lower than rated, while that of the tankless water heaters was only 10% lower. This paper will discuss the causes, consequences, and possible ramifications of this reduced efficiency.
Results of Minnesota’s Public Buildings Enhanced Energy Efficiency Program (PBEEEP)
The State of Minnesota’s Public Buildings Enhanced Energy Efficiency Program is modeled after other successful utility programs. PBEEEP seeks to transform the existing building commissioning market in Minnesota from an audit based approach to a data-based investigation.
Small Business Energy Efficiency: Roadmap to Program Design
Designing a successful small business retrofit program requires a paradigm shift from traditional energy efficiency programs.
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.
