Minnesota codes and standards efficiency programs

What is the best way to accelerate the development and adoption of energy efficient technologies? Codes and standards programs are the most cost-effective of all the program options utilities can choose, according to a recent LBNL report. Why? Because standards can impact all major equipment, and codes can impact all buildings, giving the program the widest possible deployment footprint. Continue reading

Illinois code advancement

Can utilities affect changes to building codes to improve energy savings? How feasible is it for utilities to increase cost-effective energy savings by influencing state or local building codes? We worked with an Illinois utility to find out. We reviewed information on how other states, most notably California, incorporated code programs in their portfolio. We investigated methods for attributing savings from these programs and interviewed Illinois stakeholders for their perspective on opportunities for code programs. Continue reading

Energy and new homes in Minnesota

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? Continue reading

Refrigeration in commercial and industrial settings

Refrigeration is a massive energy consumer in commercial and industrial buildings. According to the International Institute of Refrigeration's Role of Refrigeration in the Global Economy, it consumes around 17 percent of all electricity in the commercial sector alone. Rising demand and a warming climate mean almost certain expansion for refrigeration. This also means tremendous opportunity for energy savings; effort has gone into implementing many measures to reduce energy use in refrigeration across the country. Continue reading
