slide8
To find cost effective ways to improve the energy efficiency of Habitat homes

To calculate energy profiles of home designs developed by the Floor Plans Team for use in presentation by the Software Team

Create a model of a Habitat house within the Energy 10 software

Simulate the energy use of a home for a year

Make modifications to the base model and compare to current design

Compare energy savings to cost of design changes

Habitat for Humanity - Energy Efficiency Team

Goal

Approach

slide9
Energy 10 Inputs

Floor plan

Air infiltration model

Lighting profiles

Local utility costs

Shading

Insulation

Weather

Base Mode Simulation Results

92,000 kBtu annual energy use

$800 annual energy cost

60% due to heating

Habitat for Humanity - Energy Efficiency Team

Energy 10 /Base Model

slide10

Habitat for Humanity - Energy Efficiency Team

Modifications of Base Model

  • 2x4 vs. 2x6 exterior walls
  • 1’ vs. 2’ overhangs
  • Central Air vs. Window air conditioning
  • Furnace Efficiency
slide12

Habitat for Humanity - Energy Efficiency Team

Exterior Wall - Annual Utility Costs

  • 2x4 exterior wall $ 495
  • 2x6 exterior wall $ 462
  • Annual Savings $ 33

Modification Cost (16 in. oc) $ 300

Modification Cost (24 in. oc) $ 240

slide14

Habitat for Humanity - Energy Efficiency Team

Overhang -Annual Utility Costs

  • 1’ Overhang $ 448
  • 2’ Overhang $ 444
  • Annual Savings $ 4

Modification costs are not considered, the expense difference is minimal

slide15

Furnace Efficiency -80 vs. 90%

slide16

Habitat for Humanity - Energy Efficiency Team

Furnace Efficiency -Annual Utility Costs

  • 80% Efficient Furnace $296
  • 90% Efficient Furnace $263
  • Savings $ 33

Modification cost $400

slide18

Habitat for Humanity - Energy Efficiency Team
