Teaching Center (Garage)
Insulating Concrete Form (ICF) building system:
· 6” concrete within 2.5” insulating foam forms, with plastic connectors and steel rebar reinforcement
· High impact resistance, good safe room system
· R-22 continuous wall insulation – highly energy-efficient
· Fast construction, little waste
· No need for wall drainage plane, vapor retarder, air barrier
· Treated window bucks, roof framing for termite resistance
· Cost 2-7% more than standard wood frame
Slab on grade just above base flood elevation (BFE) with:
· Extra durable plastic sheeting under slab and grade beams prevents moisture wicking to walls, flooring
· Low water-to-cement ratio (<.47) + reusable wet curing blanket – increases strength, prevents curl
· Fly ash, slag, cement mix – recycled content, adds strength
· Post tension system for expansive soils – to prevent spreading of cracks (Note: expect concrete to crack)
Plumbing:
· Torchless crimped copper pipe fittings - fast, safe
· Low-flow, power assist toilets – in wall, low noise
· Low-flow urinal with smart sensor valve
· Hands-free & universal design faucets, sink
Roof:
· Borate-treated wood for termite resistance
· Grid marked decking for fast, precise installation
· Synthetic roofing felt
o Extremely tear resistant (withstood Katrina and Rita)
o Lightweight, fast installation, 180 day UV exposure
· Standing seam metal roofing, no exposed fasteners
o “cool color” hi-tech pigment reflects heat like light color
o long life, recycled content, wind resistant
Design:
· Hip roof sheds water away, shades all sides
· Detached garage protects home from auto exhaust, chemicals
o Also creates breezeway for screen porch
Fortified features (to resist 130 mph wind & flood damage):
· Steel rebar ties concrete walls to slab
· Top plate connected with anchor bolts in concrete wall
· Hurricane plates, straps wrapped over each rafter anchor roof
· Hip roof naturally more wind resistant
· Ring shank nails, close nailing pattern secure roof decking
· Roof decking seams sealed with bitumen roof tape (secondary water barrier from storm water damage)
· High-wind & impact-rated garage door, doors, windows
· “Dry floodproofed” bottom 3 ft. exterior
· Flood resistant materials – concrete, rigid foam, paperless drywall, stucco
Energy saving features of Teaching Center:
Passive solar (sun control)
· “Cool Roof” – solar reflective with high emissivity (painted metal)
· Radiant barrier coating under roof deck
· Roof overhangs shade windows, walls – hip roof
· Low-e glass (SHGC < 0.4)
Tight construction
· concrete walls plus air sealed openings and ceiling
· ICAT recessed lights & surface mount lighting
Continuous insulation
· R-22 continuous foam walls
· R-38 stabilized cellulose over ceiling
· Insulated doors, windows
Efficient HVAC & HW systems
· SEER 18, two-stage A/C with ozone-friendly refrigerant
· Gas tankless water heater – for both water AND air
o space saving, no standby loss – 30-50% more efficient
o endless hot water, whole house, no temp. fluctuation
o used with heat exchanger to heat air (without furnace)
· Fresh air duct & smart flow controller for good IAQ
· Small dehumidifier for healthy RH < 50% (when cooling not needed)
Efficient lighting & appliances
· High color fluorescent fixtures, compact fluorescent lamps
o 2/3 less energy, 2/3 less heat, appealing light
· Energy Star refrigerator, dehumidifier
