Agenda

• Where do detention facilities use energy?
• How much can be saved?
• When to consider energy efficiency?
• How much do energy efficiency projects cost?
• Examples of energy efficient detention facilities
• Resources available to help local governments

3
Where Do Detention Facilities Use Energy?
Historically 3-8 of Total Budget Projected
5-12 of Total Budget due to recent increases
4
How Much Can Be Saved?
20-30 cost savings
5
When is the Best Time to Consider Energy
Efficiency?
6
How Much Do Energy Efficiency Projects Cost?

• For new construction projects
• Cost of energy efficiency measures is
  minimal--typically less than 1 of total project
  cost
• If projects are incorporated early in the design
  process, there may be no cost

The Benefits of Energy Efficiency- Ventura County
Juvenile Justice Center
Planned 200,000 sq feet, 420 bed
facility--detention housing, administration,
education and multipurpose (40
million) Recommendation Install energy efficient
lighting, skylights in lieu of clerestories, and
heating, ventilating and air conditioning
modifications

• Pre June 2001
• Estimated annual electric cost 324,317 or
  770/bed
• Incremental cost 194,000
• Annual cost savings 72,300 (22 reduction)
• Payback 2.6 years
• IRR 38

• Post June 2001
• Annual electric cost 580,000 or 1,400/bed
• Incremental cost 194,000
• Annual cost savings 130,000 (22 reduction)
• Project payback 1.5 years
• IRR 68

Some projects could be included into the design
at no additional cost.

The Benefits of Energy Efficiency- Alameda County
Santa Rita Jail
Existing one million square feet 4,000 bed county
jail Received two loans from the Energy
Commission to install energy efficient cooling
and energy generation system (1 MW photovoltaic
system)

• Pre June 2001
• Estimated annual electric cost 1 million
• Loan amount 2 million
• Annual cost savings 240,000 (24 reduction)
• Payback 8.3 years (loan)
• IRR 10.3

• Post June 2001
• Annual electric cost 1.3 million
• Loan amount 2 million
• Annual cost savings 312,000 (24 reduction)
• Project payback 6.4 years
• IRR 14.6

The County will be using 15 less electricity
than it did in 1999 and its electricity cost is
estimated to be about the same as 1999 even
though electricity costs have increased.

  reduce energy costs
• Many programs available to help
• Energy Partnership Program Technical Support
  Available
• Low interest rate, simple to apply loans
  available from the Energy Commission
