Opportunities for cost-effective energy conservation in adaptive-reuse: Beth-Anne Elder housing case study

摘要

As part of an on-going partnership between Bethel New Life, a community housing development organization, and Argonne National Laboratory, a U.S. Department of Energy multi-purpose research laboratory, engineers and analysts from Argonne examined the opportunities for cost of rehabbing, operating, and maintaining in an adaptive reuse project being planned by Bethel. The facility is the Beth-Anne Residence for the Elderly. The project holds research interest for Argonne because it may provide opportunities for (1) demonstrating cost-effective techniques and technologies that minimize total energy costs and associated operating costs in adaptive reuse rehabs as well as (2) transferring technologies to community development organizations. Owing to the fact that the same organization will both incur the costs of the rehab and the operating costs of the facility after construction, Bethel New Life has an interest in determining not only the lowest cost of rehab and the lowest operating costs, but also determining the optimal tradeoff between increased one-time capital costs and lower operating and maintenance costs. This case study report includes the ideas developed by an Argonne team for life-cycle cost reductions and energy conservation. The ideas should not be taken as an optimization of building systems since no explicit modeling has yet been completed. Furthermore, these ideas can not be taken as a proposal for joint work because such work would need to be preceded by authorization and funding from the Department of Energy. Nevertheless, it is hoped that this report will be found useful as the rehab proceeds through the engineering phase.
