Research Report - June 17, 2014

The urban heat island (UHI) effect is a global phenomenon in which dark, impermeable surfaces and concentrated human activity cause urban temperatures to be several degrees hotter than those in surrounding areas. Urban heat islands impose negative effects on local and global public health, air...

Fact Sheet - June 12, 2014

A broad range of engine and vehicle technologies are now available or under development to increase the fuel efficiency of heavy-duty vehicles beyond the technologies needed to meet the existing fuel efficiency and greenhouse gas standards, adopted in 2011. An analysis by ACEEE and four other...

Research Report - June 11, 2014

The energy utility industry is facing many challenges, with sales stagnating, use of distributed generation growing, infrastructure aging, and environmental regulations tightening. In the past utilities, could make money by serving growing loads and earning returns on the large capital...

White Paper - May 28, 2014

Tenant engagement programs encourage the people who live in a multifamily property to change their behavior in order to achieve a goal. These programs are an attractive option for owners or managers who want to improve energy efficiency. In this report, we assess the key features of existing...

Research Report - May 13, 2014

Commercial buildings consume 20% of the total energy used in the United States, a significant portion of which can be saved through comprehensive retrofits that take into account the interactive effect of the energy use of the various energy systems in the building.

While many utility...

Research Report - April 30, 2014

This study evaluates the implications of using end-use energy efficiency to reduce greenhouse gas emissions from the power sector. It does so by quantifying the energy, economic, and pollution-reduction impacts of selected energy-saving policies on a state-by-state basis. We evaluate four of the...

Policy Brief - April 09, 2014

In reauthorizing federal transportation programs, Congress should:

  • Broaden the National Freight Policy to include all freight modes
  • Expand required freight performance measures and targets to include modal balance, resiliency, and energy efficiency
  • Ensure adequate...
Research Report - April 09, 2014

In the absence of federal requirements for energy savings, states are leading the way with effective, forward-looking energy efficiency policies. More than half of them have adopted energy efficiency resource standards (EERS), policies that set long-term mandatory energy savings targets for...

Research Report - March 26, 2014

As efficiency programs gain wider traction as a utility resource, the need increases in step for high-quality, comprehensive and consistent data metrics on energy efficiency program costs and cost-effectiveness. In this report we review utility-sector energy efficiency program costs in recent...

Research Report - March 18, 2014

This report evaluates outsourcing as a tool for achieving the energy efficiency program goals. 

While offered to industrial and other large facilities primarily to ensure the reliability of energy performance, energy service outsourcing can also enhance energy efficiency in these...
