Energy Savings Efficiency Workshop Our Mission

Energy Savings & Efficiency Workshop

Our 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 2

“If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted… CO 2 will need to be reduced from its current 387 ppm to at most 350 ppm. ” NASA climatologist Dr. James E. Hansen, 2008 3

Getting to 350 by 2050… Dramatically reduce the use of fossil fuels through energy efficiency 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 5

What can you do? Take the challenge… 6

What is the challenge? • It’s about faith groups cutting carbon dioxide (CO 2) 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 7

Ways to meet the challenge… • Get an Efficiency Maine Energy audit of your faith community building • Use the online Cool Congregations Calculator at www. coolcongregations. com • Use the tools provided by Maine Interfaith Power and Light to avoid energy use and consume energy efficiently • Choose your own path for reducing CO 2 8

Energy Efficiency and You… Benefits of energy efficiency: • Increases comfort • Lowers energy bills • Hedges against energy price hikes • Builds home equity • Promotes energy independence • Reduces CO 2 footprint • AND it pays for itself! 9

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 10

Priority areas for energy efficiency savings… • Heating • Building Envelope & Insulation • Hot Water • Lighting 11

Heating 12

To improve the energy efficiency of your heating system you will need to: • Compile heating fuel use history • Determine building & heating system efficiency • Identify problems • Identify cost effective solutions 13

Determine building/heating efficiency Calculating a heating efficiency indicator Annual Fuel Use (gallons) Square Footage of Heated Space 15

Determine 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! 16

Determine building/heating efficiency Calculating a heating efficiency indicator EXAMPLE #1 (avg Maine home) (annual fuel use) 1000 gals =. 5 (sq ft of building) 2000 17

Determine building/heating efficiency Calculating a heating efficiency indicator Building (8, 000 SF) 1, 350 gallons/ 8, 000 SF = 0. 17 gals/SF (In floor radiant heating, R 50 in attic; boiler fire rate 1. 25 gal/hr) 18

Determine building/heating efficiency Calculating a heating efficiency indicator Building (13, 000 SF) 11, 600 gallons/ 13, 000 SF = 0. 9 gals/SF 19

Common issues Use of analog thermostats • Replace manual thermostats with programmable digital: up to 3% savings! • Hire a professional to install an outdoor air temperature sensor to control boiler to smooth the transition from cold to warm: 10% - 20% savings! 20

Common places for air leaks ice dams 10/08/10 insulation / envelope 26

Eliminate air leaks Sill plates At a minimum insulate the sill plate area to prevent cold air infiltration 27

Eliminate air leaks install door sweeps and weather stripping insulation / envelope 28

Eliminate air leaks plumbing penetrations

Eliminate air leaks Can lighting Remove can lights OR build an insulated box around lights 30

Eliminate air leaks Attic hatches Heat loss 31

Insulate R-value = resistance to heat flow The higher the R-value the better! 32

Insulate Start with the attic! R 19 Over 20 inches of blown in cellulous R 49 33

Insulate windows 34

Insulated doors (R 12) in place of wooden doors (R 1) T EA H S OS L ! 35

Insulate basement walls Heat loss through a basement accounts for 15% to 30% Masonry Foundation 36

Hot Water 37

Hot Water electric or gas heater boiler coil hot water 38

Hot Water Common 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 39

Hot 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 hot water 40

Hot Water On demand, tankless heaters • 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 41

Hot Water Insulate hot water piping Heat loss with no insulation 42

Lighting 43

Assess lighting needs • Take inventory of lights • Inventory should by type and by area (room, hallway, etc. ) Note: be mindful of minimum lighting requirements (e. g. adequate lighting in stairwells) • Estimate hours per week that lights are on 44

Lighting • Turn off lights • Adjust lighting levels to match needs and remove unneeded lighting • Make use of free day lighting • Use high reflectance ceiling tiles and light colors to carry daylight into interior space. 45

Lighting Replace incandescent bulbs with compact fluorescents wherever possible. 46

Special Considerations for Faith Communities 47

Special Considerations for Faith Communities Schedule activities on common days to save energy 48

Special Considerations for Faith Communities Sanctuary ceilings often a problem area Sanctuary Ceiling R 1? 49

Special Considerations for Faith Communities address air circulation (especially in sanctuaries) Airius Thermal Equalizers • Installation of the units will help to stabilize the temperature • Peak ceiling temperature are 5 to 10 degrees warmer than the floor. • Reported fuel oil savings 10 -20% • Available at Maine Green Building Supply in Portland 50

Special Considerations for Faith Communities Lighting • Replace incandescent bulbs with compact fluorescents (CFLs) wherever possible. • Replace T-12 fluorescent fixtures with energy saving T-8 fixtures and electronic ballasts. T-5 T-8 T-12 • Replace incandescent and fluorescent exit signs with light emitting diodes (LEDs) or the latest solid-state technology. 51

Special Considerations for Faith Communities Lighting: install occupancy sensors • Install occupancy sensor switches in seldom used areas: • Passive Infrared (PIR) which detects body heat • Ultrasonic (US) units which detects body movement. • Install controls on exterior lights. • Install motion sensors, time clocks, or photoelectric sensors on exterior parking lots and security lighting. 52
