Computer Model
- Entire building
  - Allows you to evaluate any change / idea
  - Basis on all incentive programs
- Walls
  - WUFI (catches vapor/condensation build up)
Strategy
- Passive
  - reduce your demand...then meet the low demand
  - Work with the natural system
- Prioritize...heat, cooling, lighting, hot water = 90% of energy
  - Insulate the envelope ... Building Science - Perfect Wall
    - Roof = 60R
    - Floor = 25R
    - Walls = 30R
  - Eliminate Thermal Bridges (focus on walls)
    - All connect points
      - Walls-to-Roof
      - Walls-to-Floor
      - Walls-to-walls
      - Window and door framing
      - Wall framing
  - Air Infiltration (focus on walls, windows and doors)
    - < 1 Air Exchange per hour
    - ALL building seams
      - Windows and Doors seals and framing
        Walls-to-Roof
        
        Walls-to-Floor
  - Windows
    - Window-to-wall ratio not > 27%
    - SHGC = .3 or below
    - Windows U = .27 or below
    - Eliminate Doorwalls
HVAC Recommendations
- Size to the actual loads ... use modeling
- Most HVAC equipment is at least 50% oversized
Materials
- spray foam for all cracks
- cfl bulbs inside and induction outside
- aircrete for walls
- mix insulation
  - cellulose to absorb humidity
Incentives
- IRS = Efficient Buildings
- DTE Yes
- Smart Buildings - DEGC

+* Need blower door test (write Ken Byczynski @ Kenco <kencoenergy@core.com>)
+* Get quote
+* Also ask for his thermal inspection of current building
+==== Comfort ====
+* On the floor plan indicte where the building is hot in the summer and cold in the winter.
+* Identify any drafts
