EXPERIMENTING WITH EFFICIENCY

Washington DC Team: Millennial Makers March 14th 2014

Problem Statement

Labs account for 40-50% of university energy use

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

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

Freezers 3.00% 1.79%

Fume Hood 12.00% 8.00%

Centrifuges 0.24% 0.24%

Vacuum Pumps 1.68% 1.40%

Building Systems 39.90% 19.95%

Total Potential Savings from University Recommendations

56.82% 31.38%

AGENCY ROLE

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
