Retrofitting Forced Air Combi Systems
This project analyzed combined condensing water heaters or boilers and hydronic air coils to provide high efficiency domestic hot water (DHW) and forced air space heating.
Direct Install Plus Multifamily Pilot Program - Final Report
The Center for Energy and Environment designed, recruited participants for, and completed a pilot program for 10 multifamily buildings with a total of 306 units to determine the viability of a “direct install plus” program design for Minnesota apartments.
Field Assessment of Energy Audit Tools for Retrofit Programs
This project field-tested three different building performance models of varying complexity, in order to assess their value as rating systems in the context of a residential retrofit program.
Home Energy Improvement Index
This paper describes CEE's Home Energy Improvement Index which is designed for use with residential energy efficiency programs, specifically targeting cost-effective retrofits for existing homes.
Program Results from the State of Minnesota's Existing Building Commissioning Program
Energy investigations of 227 Minnesota buildings identified best practices for program managers. A rigorous quality assurance experience highlights the need for a training and certification process for EBCx providers.
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.
