This article is part 2 in a series on deep energy retrofits (DERs). The series describes in-depth end-use monitoring in ten DERs in Northern California. The Lawrence Berkeley National Laboratory (LBNL) conducted the monitoring. In part 1 of this series (May/June ’12, p. 38), we characterized ten DER projects as either “remodels” or “retrofits.” The six remodels were described in detail. In addition to exhaustive energy upgrades, these homes underwent the most structural and aesthetic intervention, and most of them did not resemble the home in its preretrofit condition. In this article, we will describe the four retrofits. In general, these projects kept the same look and feel as the preretrofit home, but made thorough upgrades to all systems and to most elements of the building enclosure. Renewable energy installations were added in several homes. In some cases, the homeowners chose this approach for purposes of historic preservation. In other cases, the home was new enough that it was not necessary or desirable to make major aesthetic or functional changes.
