Recent economics lead to challenges in meeting operating costs for collections-holding institutions. This has spurred interest in means to reduce annual operating costs by reducing energy use. This paper presents the potential energy savings from various energy conservation measures (ECMs) that can be done without relaxing the environmental criteria or otherwise placing collections at risk. These ECMs are then compared to the energy saving from relaxing the environmental criteria from 20-22 degC @ 45-55% RH to 15-26 degC @ 40-60%RH, a savings analysis presented in the paper at last year's meeting.
The savings are based on a block load analysis in a hypothetical building meeting ASHRAE Standard 90.1 for the building envelope, and ASHRAE Standard 62.1 for outside air. The collections space analyzed for savings is a typical museum gallery/collections use spaces in the Montreal climate.
Energy rates are presented in a form so that the reader can easily convert to actual rates at their institution to project their ECM savings, with an example provided. In making the comparison, in addition to energy use, each ECM is evaluated and compared for its global carbon dioxide emissions for the energy as used in Montreal.
