Key Recommendations
Federal Agencies• Energy efficiency criteria in awarding grants• Energy Star Rating for Lab Equipment
Universities• Lab Standards• Behavior Change Program• Financial Incentives
Breakdown of Lab Energy Consumption by End Use
Freezers; 7.1%Fume
Hoods; 16.0%
Cen-trifuges;
1.2%
Vacuum pumps; 2.8%HVAC; 66.5%
Other; 6.4%
University Role: Buildings Standards
Ventilation standards
Building standards
Retro-fits
Metering
• VAV fume hoods: up to 50% savings
• Reconsider standards• Add controls
• Require 30% + reduction from ASHRAE 90.1 2004
• Potentially 30-60% reduction in energy use
• Accountability (2-5% reduction in energy use)
• Behavior change programs
University Role: Behavior Change
Behavior change programs• Set individual goals for labs and collect data from VFDs
• Setting back freezer temperatures: save 30% energy
Equipment purchase subsidies• Stanford’s “cash for clunkers” freezer program
• Harvard’s program subsidizes Stirling freezers
• 30- 50% less energy
Summary of Overall Savings Potential
Overall Lab Energy Reduction Potential
Measures High Case Low Case

Agency Role: Energy Star
For Lab equipment
Ultra-low freezers:
20 -50% savings
Lead the market to more efficient equipment
Demonstrate efficient practices
Agency Role : Grant Criteria
• LEER Program• Prioritize grant award based on energy efficiency
measures
Prescriptive Method
Proportion of Energy Star Equipment
Performance Method
Energy use:- 15% < Labs21 benchmarking tool
Agency Role : new grant program
Dedicated Facilities Improvement Grant to advance energy efficiency in labs• HVAC, controls, sub-metering, etc.
Expansion of Extramural Research Facilities Improvement Program
Assist labs in meeting LEER standards
$500,000-$1 million over a 5 year period
Supplement, not replace, university investment
Conclusion
30-50% saving
potential
Accountability of University and
Individuals
Energy Efficiency encouraged in
grants
Standards for lab and lab
