"As Is" Building - Discovering What Is

"All great work begins with observing and becoming more deeply aware of the current reality."

Energy Usage

  • Utilities
    • Electrical
      • Number of Meters =
      • Electric Bills for 3 years (provide in hard copy)
    • Gas
      • Number of Meters =
      • Gas Bills for 3 years (provide in hard copy)

Building Usage

  • Thermostat Settings
    • Heat =
    • Cooling =
  • Typical number of people in the building
    • Last 3 years

HVAC Equipment

  • Heating
    • Number of Furnaces
      • for each Type / Energy Input (e.g. gas) / Size / Make / Model / Year
      • Photo of equipment and id plate
    • Number of AC Units
      • for each Type / Size / Make / Model / Year
      • Photo of equipment and id plate

Duct System

  • Current Duct System
    • Supplies and Returns on a floor plan

Building Envelope

  • 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


Energy Modeling Input Data Requirements

Energy Modeling Checklist

Building Recommendations (Burt)

  • 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
