Guest Lecturer:
Josh A.
H.B.E.E.R. (House Boat to Energy Efficient Residences)

- Energy Strategy:  Aesthetics, Functionality, Performance -
  #'s ($) to materials:  $1.00/day.  Components' durability -
  human thermal comfort.
- "Details For Passive Houses" book.  (German hemp
   fiber, lambs wool, rock wool).
- European Construction Materials:  latent load in summer:
  remove moisture from the air. 

- Mini-Slit-System:  no ductwork, steadier temperature.
- Building Envelope Components:  poly-iso, EPS, HD
  fiberglass, blown-in cellulose, BATT insulation.
  Spray foam insulation is "over-rated."

- Concept:  Martin Franks, Spencer Dohrman.
  Joe Tanney:  Module - aesthetic
  Pod & Panel -  Modular vs. ALL S.I.P.S.
  Pre-Fab utility core - floor plan flexibility.

- Fisher S.I.PS., Louisville, KY.:  $5.00/sq. ft.
  Wood frame (ceiling, roof, floor), hybrid -
  envelope design, no single system for air barrier.
- Must construct an air-tight wall detail to get a
  "real" R-value.
- Each module is self-supporting structurally:
  NOT faster to build - $115,000 construction cost
  (Stardust, the boat builders) - 50 - 75% higher
  construction cost over conventional construction
  using the S.I.P.S. hybrid method.

- Kentucky Highlands market studies, federal
  incentives, surplus of existing housing.

- Folding truss system allowed for a "cathedraled"
  ceiling.  20 hour estimate to install the trusses
  ended up taking 160 hours.

- Air barrier system:  OSR or plywood - glue-tape
  the seams.  Vapor retarders.
- HVAC:  internal loads vs. external loads.

- Residential:  Relying on infiltration for fresh air, loose
  control of the "equation."

- Universal Force Design:  truss design

- Passive House Design Software:  simulation software

- ASHRAE Handbook:  reference for material heat gain
  and loss.
- IECC:  International Energy Conservation Code
- Zip system sheathing.
- Many design professionals do NOT know how to
  detail air-barrier systems.
- (9) air-changes/hour required for a standard
  residential house.
- Home performance:  Energy Star.
- LED lighting used at HBEER.




  HBEER Vendors/Manufactures:

- Fisher SIPS:  Louisville, KY.
- Casteel Woodworking:  London, KY (casework,
  maple plywoods, solid maple fronts.)
- Monticello Hardwoods:  Monticello,KY  (flooring).
- Pella Imperial Windows:  Murray, KY
- GE appliances.
- Renew Air - ERV:  EV70 (indoor unit).
- Fujitsu ductless mini-split:  carrier, condenser, evaporator - 
  high density heat transfer tube arrangement - steady flow
  of air helps maintain a constant temperature.

- Blown-in HD fiberglass insulation.
- Hunter NB (poly-iso):  H-shield NB on wood deck -
  used at cathedral ceiling.
- DOW:  foil faced poly-iso, closed cell foam.
- CAER/ASHRAE:  70 cfm/minute of air must circulate -
  residential code requirement.
