Saving energy at a Denver hospital

摘要

A s an example of the impact of achieving the target energy savings, information and projections for a new, large, energy-efficient hospital in the Denver area are shown. Actual energy usage has been tabulated and graphed, with the AEDG 50% energy use target entered to calculate projected annual energy cost savings. This facility currently is consuming 210,000 Btu of energy per year, well below what we typically find for new hospitals. Annual utility cost is slightly more than $1.6 million. If the AEDG 50% reduction goal of 107,000 Btu/sq ft for climatic zone 5B is obtained, with the same proportion of electrical and gas use, savings would be more than $800,000 per year.
