1 Stewardship is Green Dr. Alan Hoback, PE Rev. Steven Archer

2 Outline Welcome and Overview Perspectives on the Environment Energy Improvements Work Session

3 Presenters Dr. Alan Hoback, PE Director of Architectural Engineering at UDM University of Detroit Mercy: a Catholic Inst. Architectural Engineering: building energy systems Rev. Steven Archer Trinity St. Marks United Church of Christ Southwest Detroit Neighborhood

4 Overview of Trinity St. Marks UCC Urban Southwest Detroit Booming middle class neighborhoods in early 1900s

5 Work done at TSMUCC 2008 Electric: Update tube lighting Replace incandescent bulbs with CFLs Exit signs Heat: Eliminate drafts Supplemental heat system

6 Utilities Expenses ¼ savings in heat and eletrical

7 Work still to be done Electrical: Replace dimming bulbs in large fixtures. Supplement insulation in attic and office. Parsonage

8 Outline Welcome and Overview Perspectives on the Environment Energy Improvements Work Session

9 Perspectives on the Environment Engaging the Congregation Urban Context Making the Problem Local Making the Problem Global

10 Making the Problem Local Problem is too big for most people. Break it down to the village.

11 Urban Context tennessee.gov

12 Health 6,000 deaths in Ontario from Asthma caused by US smog. Ontario CAN 13 M people Of 92,000 total deaths per year.

13 Making the Problem Global Why? How?

14 Glaciers Glacier runoff year- round Causes productive ecosystems that would otherwise be less productive.

15 GlaciersEcosystems Abundant Ecosystems cause high density of population. 1/3 of world population!

16 GlaciersEcosystemsPopulation.

17 GlaciersEcosystemsPopulation. Global Climate change is partial cause of the glaciers melting. No longer a year long supply of water.

18 GlaciersEcosystemsPopulation. What is going to happen to 1/3 of the world population?

19 Thats why The world is one living organism. All organisms share the same DNA structure. We are the same organism just divided, changed, and recombined.

20 Making Global Relevant African American High School Students America.gov

21 Engaging the congregation Generation Y Start small? Sewing a seed

22 Starting small forms

23 Recycling / Composting Trash trucks get 2 mpg. 1.5 lbs of air pollution (smoke & carbon monoxide & carbon dioxide) to haul away and bury 1.0 lbs of trash. No immediate economic payback to congregation, unless you pay for trash by weight.

24 Outline Welcome and Overview Perspectives on the Environment Energy Improvements -strategies -specific improvements Work Session

25 Outline-Energy Improvements Unique strategies. Finding technical advice and labor. Paying for it. Improvements: Electrical improvements. Heating & A/C improvements. Water. Misc.

26 Unique Strategies Variation in use patterns. Sanctuary use. Office use. Climate regions Building age

27 Avoiding Mistakes Insulating the wrong way can cause mold growth. Putting in the wrong product can cost you more. Look past product claims that may save up to 50%. Environmental Problems: Radon

28 Radon

29 Finding technical advice and labor Energy Audits ($ ) Energy Consultants Volunteers / DIY

30

31 Paying for it Pay back simple analysis, example: TSMUCC $6,000 lighting upgrades 2008 Net savings $1,260 / yr Cash flow $6k $1.2k Paid off in 12

32 Example Heating Season OutlayEffect on energy bills Running Total $4,000 cost $10,000 savings Net $6, $10,000 savings Total: $16, $10,000 savings Total: $26, $10,000 savings Total: $36,000

33 Paying for it Loans Private consultants $6k $1.2k Cash flow debt

34 Strategies for Paying for it Grants Deep pockets Reinvestment of savings Rising costs $6k

35 Outline Welcome and Overview Perspectives on the Environment Energy Improvements -strategies -specific improvements Work Session

36 Electrical Improvements Interior Lighting Exterior Lighting Air Conditioning Appliances

37 Variability in rates In Michigan each watt continuously running is $1 per year.

38 Interior Lighting Church lighting atmosphere: Light color and focus.

39 Interior Lighting Compact Fluorescent Light bulbs (CFL) Paying for: In the right fixture:

40 CFL Issues Proper disposal Last 4X incandescent Energy Star & Power ratio Circuit stability Special dimmer switches Warm up & Loss of brightness Quick Start Cold Cathode (dimmable, instant on, cold climate)

41 Tube Lighting Old Magnetic Ballasts Efficient electronic ballasts (25%) Light levels Energy Consultants vs. Volunteers

43 Sensors On tubes or CFLs One Exterior lighting

44 Exit signs Incandescent yearly electrical cost: $ /fixture 1 or 2 bulbs Fluorescent: $ LED $ replacement: $17 + labor EXIT

45 Exterior Lights CFL (need many) High Intensity Discharge LED ($$$) Sensors?

46 Air-conditioning Window and Central Units Efficiency is SEER (Seasonal Energy Efficiency Ratio) Knowing energy consumption, you could find potential savings from upgrading to newer units. See similar points in Heating discussion.

47 Shading torontohistory.org

48 Appliances Refrigerators How much electricity does it use? Watt Meter ~$25

49 Appliances - other Most used for very short time Continuously running appliances: Refrigerators 16 cu. Ft725 W (when compressor on ) Dorm sized100 W Clock radio = 10 W Fans Ceiling = 65–175 W Window = 55–250 W Furnace = 750 W Whole house = 240–750 W VCR / DVD Player on / off20 W / 5W Personal computer CPU - awake / asleep = 270 / 60 W or less Laptop = 50 W

50 Heat (and A/C) Drafts Programmable Thermostats Insulating Zoning Supplementary Heat Systems Replacement furnace (high efficiency or geothermal)

51 Drafts Trinity St. Marks UCC Caulking Vents:

52 Replacement Windows If very drafty: pay back in 4-8 years. If aluminum frame: (single pane or older double pane.) pay back in years. Or Window Film could save ~18% energy

53 Windows Lead Outer protective windows.

54 Draft sealing: Costs Professionals: About $300 Volunteers: less than $100 in materials Savings: 5-25% of heating & cooling costs.

55 Insulating Ice dams

56 Insulating Cost: $0.50 / sq. ft. (w/ volunteer labor) $1.00 / sq. ft. (professional) Savings: Air conditioning load reduced or comfort improved Heat: Payback ~2 years depending on climate zone and current insulation.

57 Instrumentation & Controls Programmable Thermostats Zoning

58 Use Patterns Programmable Thermostats: Can control days by day and hour by hr. If building is unoccupied during night: Turn back at night by degrees. Savings: 10% If building is unoccupied during week: Savings: 20-30%

59 Use Patterns Zoning: Controls split forced air or steam to needed areas only. Sanctuary 55 o M-S Office and classrooms o M-S Sanctuary 72 o Su Office and classrooms 72 o Su

60 Zoning Costs: $2,000-$5,000 per building. Savings: Up to 30% based on portion of building zoned.

61 Use patterns Trinity Saint Marks UCC

62 Trinity St. Marks UCC Pipe Organ. Constant 68 o Sanctuary 70 o Su and events Office and meeting. 68 o M-Su daytime Fellowship Hall. (Secondary users) 68 o M-S daytime

63 Supplementary Heat System Secondary furnace. Ties to existing exhaust. Independent boiler system. Longer payback.

64 Updating Furnace High Efficiency Furnace installed: $20,000- $100,000 Up to 50% improvement in heating costs. Geothermal Heat Pump (similar $s) works best in saturated soils or ponds

65 Water Hot water Watering Lawn

66 Hot Water Building use 2 hours? On-demand warms as needed. Satellite on- demand systems. Kitchen and baths Bathroom bathroom

67 Water Shortages / Price increase

68 Lawn & Garden Watering Native Species Rain Sensors

69 Misc. –Energy Improvements Renewable Energy New Construction

70 Renewable Energy Windmills Photovoltaic Solar Hot water Solar

71 Windmills $8,000-$20, year payback (in white) 8 years in orange

72 Photovoltaic Solar $16,000+

73 Hot water solar Supplement water heater. Store heat until winter.

74 New Construction Leadership in Energy & Environmental Design. (LEED) Silver, Gold, Platinum ratings Get points for Energy and Environment (Internal environment: air quality) (External environment: impact on nature.)

75 Outline Welcome and Overview Perspectives on the Environment Energy Improvements Work Session

76 Prioritizing based on unique situation

77 Your unique situation See provided sheet. Building use Climate High wind or solar region?

78 Find the bills What is the annual heating cost and all- inclusive rate? (by month) What is the annual electrical cost and all- inclusive rate? (by month) What is the annual water & sewer cost and all-inclusive rate? (by month)

79 See also: Light bulb program Sample sheet created couple years ago. Costs and savings have both likely gone up. Use for your church buildings or for home use.

80 Solar Regions

81 Wind Regions

82 Electrical Rates

83 Climate Regions

84 Water shortage areas
