ENERGY EFFICIENCY PORTFOLIO ANALYSIS USING LCCA AND UNCERTAINTY ANALYSIS
Energy efficiency project investments and financing are
approved based on economics, not energy savings.
However, the consideration and modeling of economic
factors typically receives a disproportionately small
allotment of the energy analysis time budget. This
analysis paradigm often fails to adequately address the
concerns that matter most to investors, leading decisionmakers
to avoid energy efficiency projects regardless of
the opportunity available.
This paper presents an alternative, investor-centric
approach specifically geared towards catalyzing the
broad-scale adoption of currently-viable, easilycustomizable
energy conservation measures (ECMs) in
portfolios of like buildings (e.g. large office buildings).
This approach can be adopted by energy modelers to
significantly increase the adoption rate of the ECMs they
