Our MissionOur Mission

Inspired by diverse faith perspectives to care for the natural world and its most vulnerable inhabitants, Maine Interfaith Power and Light works to engage the faith communities of Maine in efforts to counter climate change through education, advocacy, energy conservation and the use of clean renewable power

“If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted… CO2 will need to be reduced from its current 387 ppm to at most 350 ppm.”

NASA climatologistDr. James E. Hansen, 2008

Energy efficiency has great potential to…

• Reduce U.S. energy use 23% by 2020 • Eliminate $1.2 trillion in waste nationwide • Avoid 1.1 gigatons of greenhouse gas emissions:

like taking all U.S. cars off the road

Energy Efficiency and You…Energy Efficiency and You…

Benefits of energy efficiency:

• Increases comfort

• Lowers energy bills

• Promotes energy independence

• Reduces CO2 footprint

• AND it pays for itself!

Energy Efficiency and You…Energy Efficiency and You…

Today we will explore…

• Where to focus: I.D. priority areas for energy efficiency savings

• How to get it done: completing & paying for energy efficiency work

• Heating

• Building Envelope & Insulation

• Hot Water

• Lighting

Determine building/heating efficiencyDetermine building/heating efficiency What the “efficiency indicator” means

.1 to .25 : efficient heating system & well insulated building: little to no action needed

.25 to .5 : investigate heating system efficiency & insulation: likely action needed

.5 to .75 : inefficient system or poor insulation: plan for action

.75+: ALERT! You’re heating the outdoors: take action immediately!

EXAMPLE #1 (avg Maine home)

(annual fuel use) 1000 gals = .5

(sq ft of building) 2000

Determine building/heating efficiencyDetermine building/heating efficiency Calculating a heating efficiency indicator

1,350 gallons/ 8,000 SF = 0.17 gals/SF

(In floor radiant heating, R50 in attic;boiler fire rate 1.25 gal/hr)

Building (8,000 SF)

Building (13,000 SF)

11,600 gallons/ 13,000 SF = 0.9 gals/SF

ImprovementEstimated Savings

Heating System Tune-up 2 to 10%

Reduced firing rate or nozzle reduction 6 to 10%

Reduced temperature of circulating water/furnace air 5 to 12%

Pipe and duct insulation 5 to 10%

Flame retention head burner 15 to 20%

New high-efficiency hot water boiler 20 to 40%

Hot WaterHot Water

electric or gas heater boiler coil

Hot WaterHot Water

Hot WaterHot WaterCommon issues and problems

• Heater and pipes not insulated

• Hot water heater temperature set too high

• Water heated when not in demand

• Water heater tied to heating system requiring boiler firing during non heating season

• Constant hot water circulation

Hot WaterHot Water

• Reduce hot water temperature: 120 degrees or less OK

• Install a timer on your hot water tank:• One congregation saved $700 in

a year• One congregation spent $150

on a timer and saw a 2 month pay back

• Heat water directly without the use of a storage tank

• No standby heat losses

• Delivers constant supply of hot water

• Cost about 10 to 20 % less to operate than standard tank water heaters

• 7 year pay back

Hot WaterHot WaterOn demand, tankless heaters

Hot WaterHot Water Insulate hot water piping

Heat loss with no insulation

LightingLighting

• Turn off lights

• Adjust lighting levels to match needs and remove un-needed lighting

• Make use of free day lighting

• Use high reflectance ceiling tiles and light colors to carry daylight into interior space.

Replace incandescent bulbs with compact fluorescents wherever possible.

Special Considerations for Faith Communities

Special Considerations for Faith Communities Schedule activities on common days to save energy

Building Occupancy Ratecommon example

Occupied6%

Unoccupied94%

Special Considerations for Faith Communities Sanctuary ceilings often a problem area

Sanctuary Ceiling R 1?

Special Considerations for Faith Communities Air circulation

Airius Thermal Equalizers

• Stabilize temperature (Ceiling temperature 5 to 10 degrees warmer than floor)

• Reported fuel oil savings 10-20%

• Available at Maine Green Building Supply in Portland

• Replace T-12 fluorescent fixtures with T-8 fixtures and electronic ballasts.

• Replace incandescent and fluorescent exit signs with LED signs.

Special Considerations for Faith Communities Lighting

Special Considerations for Faith Communities Lighting: install occupancy sensors

• Install occupancy sensor switches in seldom used areas:

• Install controls on exterior lights.

• Install motion sensors, time clocks, or photoelectric sensors on exterior parking lots and security lighting.

What can you do? What can you do? Take the challenge…Take the challenge…

• It’s about faith groups cutting carbon dioxide (CO2) and other greenhouse gases responsible for climate change.

•We suggest a goal of at least 10% over the next year. Cutting 10% is an achievable goal and is in line with what climate scientists say we need right now.

•Open to churches, synagogues, temples and all communities of faith across Maine
