Energy Design Reviews: The End of the Energy Audit?
Abstract
It is much more cost effective to design an
industrial plant upfront for optimum energy
efficiency rather than retrofit an existing
plant, yet typically design engineers and
project managers continue to focus on
capital costs, not lifecycle costs, often
ignoring substantial energy savings potential
over the 20-50 year plant life. An average
of over 30 percent in annual energy spending
relative to the business as usual design
baseline was identified in four recent energy
design reviews (EDR) for large industrial
companies. Typically, energy audits
identify energy cost savings of 5-10 percent of
energy spending, thus demonstrating the
much larger savings potential of energy
design reviews.
This paper will define an EDR, list the
benefits, compare an EDR with Leadership
in Energy and Environmental Design,
describe the methodology, present case
study results and lessons learned from four
EDRs, and conclude with suggestions on
how to incorporate energy design reviews in
your organization.
