multifamily building
Compliance with building energy codes is key to ensure home and business owners benefit from the intended energy savings. If we don’t use effective methods to understand energy code compliance, we can’t establish accurate baselines for energy efficiency programs or understand what energy savings are left on the table. Compliance insight will equip program managers to make the case for compliance improvement and enhancement programs. This is especially important for low-rise multifamily buildings. Read more
contractors discussing plans
About 13,000 new homes and several hundred multifamily buildings are built in Minnesota each year and many existing homes are added on to or renovated. How do these projects compare relative to energy code? What kinds of beyond-code energy savings opportunities are still out there and how might utility conservation programs help to capture them?

How does the Passive House Institute U.S. (PHIUS) Certification construction compare to conventional high-performance approaches to construction in affordable housing? To understand the impact, our researchers performed a field study to monitor and evaluate two different Chicago-area six-flat properties to gain valuable insights on the value of passive design.

Dilli and Scott in 1980s
In the first installment of Scott Pigg’s story, he discussed Nepal’s changed landscape that he encountered thirty years after his original visit. Scott now confronts the difficult realizations, after visiting a long-time friend, regarding climate change and how our society impacts our carbon emissions. This is the rest of his story. Read more
Nepal footbridge
Scott Pigg, principal researcher, took a trip back to Nepal this year to visit a spot where he had some personal history. Upon visiting, he had some realizations about the stark differences between Nepal’s landscape thirty years ago and today. These harsh insights support the reasons why our team at Slipstream works so hard to make a clean energy future a reality. This is Scott’s story. Read more
High energy
We conducted an in-depth study of 100 high energy consumption homes in Minnesota. The goal was to help conservation program managers better understand the factors contributing to high usage, quantify the energy savings potential associated with common conservation measures, and identify program strategies that could be used to effectively target those opportunities.

Apartment building
We also characterized Wisconsin’s rental sector based on a statewide sample of 180 rental properties, ranging from single-family rental homes to large apartment buildings. The study provided a statistically representative picture of building characteristics, appliances and equipment; benchmarked energy usage; assessed energy efficiency opportunities; and explored linkages between energy efficiency opportunities and knowledge, attitudes and behavior on the part of building tenants, owners and managers.

Multi family
We characterized energy use in Minnesota’s multifamily sector and identified untapped energy efficiency opportunities. We also explored energy-related behaviors and attitudes of multifamily building owners and tenants. Our research team sampled 120 buildings across the state; gathered information from building owners and tenants through on-line and mail surveys; and evaluated the payback period of 25 common energy and water savings measures in multifamily housing.

manufactured homes
The manufactured home market offers an affordable housing option—and sometimes the only option—for many would-be homeowners. Residents of manufactured homes (also known as mobile homes) are more likely to be low-income than residents of other single-family homes, and energy costs may comprise a larger portion of their monthly expenses.

heating and cooling system study
We conducted research on residential heating and cooling systems in Minnesota homes to help improve installation and maintenance practices for furnaces, air conditioners, and heat pumps. Read more
A recent study questioning the savings achieved by low-income weatherization programs has been generating considerable buzz in the energy efficiency community, especially after the Washington Post,  Read more
