For too long there has been relatively little EE focus on multifamily, but some new programs have recently started. This group gives us a venue to share our experiences on cost effective audit & retrofit strategies and analysis tool needs.
Latest Activity: May 13
Multifamily buildings occupy a unique space between single-family and commercial buildings. For close to two decades there has been relatively little focus on the EE performance of the construction and operational issues around multifamily buildings. Fortunately, in the last couple of years some new EE retrofit programs have begun. Let’s share our experiences. This is a good moment for HEP members to share their experience with audit activities on multifamily buildings, helping us all learn and discover cost effective audit and retrofit strategies as well as the analysis tool needs.
We’ve started these four threads to start the group discussion:
On another note, through funding from the Department of Energy’s Weatherization Assistance Program (WAP), ORNL and LBNL are beginning work on the addition of multifamily residential energy modeling capabilities to WAP and the Home Energy Saver websites (http://hespro.lbl.gov, http://hes.lbl.gov). We would like to tap the combined experience of HEP members as we start this work. The first task of the project is to form a Technical Advisory Group (TAG) to help guide the research and tool development as it progresses. Please contact me if you are interested in learning more about our work scope and think you might be interested in participating on the TAG.
For those conducting energy audits and developing retrofit work scopes for high-rise apartments, please share your experiences in this thread. Successful methods, pitfalls and complete disasters are all fair game for sharing with the group. Since…Continue

Does anyone know of professional MARKET STUDY results to assess the demand for home performance, weatherization or other related services for multifamily buildings? Please advise if you can offer any information regarding existing market studies…Continue

OK, folks -- time for some creative thinking about a 16-unit building we are trying to weatherize in SE Wisconsin.It's two stories arond a central courtyard, with most units accessed by a door direct to outside. (That is, most units have either two…Continue

Several energy efficiency retrofit programs for multifamily buildings have started up recently. New York, California and British Columbia are locations that I know of, but I'm sure there are others. In addition, some of these regions are looking at…Continue

If you haven't plugged in to the ACEEE "Summer Study on Energy Efficiency in Buildings" -- this might be a good year to do so. Every two years, ACEEE assembles experts with a vast amount of solid, peer-reviewed energy efficiency research. The…Continue

In our work, we all find our preferred tools and we develop efficient (hopefully) ways to use them. Often that process identifies many tool features and analysis capabilities that an entire community of professionals can profitably use. Please…Continue

Hey there, First post on HEP! Exciting times, indeed. A question on ACH and N-factors for multifamily: LBNL’s N-factor converts between pressure induced (i.e.- fan measured) and natural air infiltration rates. The well known N-factor charts max…Continue

Mutlifamily Weatherization?? Who knew? The National Weatherization Training Conference (December 12 to 15) is actually running an entire track on weatherizing MFBs. See …Continue
