LEAN: A Fast and Cost-Effective Way to Assess Building Energy Efficiency

Now there’s a quick, cost-effective and accurate way to generate models of building energy performance without the time and cost involved in on-site energy audits. Lean Energy Analysis (LEAN) uses regression analysis techniques combined with information from past utility bills to create the models.


LEAN goes beyond the simple energy use intensity (EUI) benchmarking comparisons or the ENERGY STAR Portfolio Manager scores commonly used today. It is now being used in the private sector to benchmark building portfolios.


LEAN provides a way to identify potential energy waste and provides insight to where specifically the savings opportunities might be for a building with poor energy performance. It can also help assess the opportunity for energy efficiency across a building portfolio and identify potential energy efficiency projects at each site.


Armed with this information, owners and managers can develop the most effective strategy to invest in energy efficiency in their buildings and get the most energy and greenhouse gas emissions reductions in return for their investments.
