Small & Medium Business

93% of the US commercial building market is occupied by small commercial businesses whose annual energy demand is less than 200kW. These same businesses account for 43% of the electricity consumption and almost 49% of the electricity expenditures. Lime brings energy efficiency and utility incentives right to the door of those businesses who need it most. In 2012 alone, Lime Energy implemented energy efficiency for almost 4,000 small and medium businesses in 6 states.  Click for more...


The US Environmental Protection Agency estimates that state and local governments spend over $10 billion annually on energy projects and services. In fact, energy accounts for as much as 10% of a local governments annual operating budget.  With a potential of 35% or more reduction in energy use in most existing government buildings, the cost savings for municipalities are in the tens of millions.  Lime has already implemented energy efficiency solutions in over 2,000 public buildings and is adding more each day.  Click for more...

National Multi-Site

Energy use is commonly the single largest operating expense for commerical buildings and in a portfolio, that number can be quite large.  For example, Lime delivered energy upgrades for over 5,700 banking facilities in 46 states, covering 33.3 million square feet and saving $7.7 million annually.  Lime also completed facility audits, rebate procurement, lighting upgrades and HVAC controls at 286 AMF locations in 36 states, saving the company nearly $2,000,000 per year. Click for more...
