  • 1.  Green building is just applying common sense. Green building is the convergence of 5 fundamental objectives  Waste management practices  Conservation of natural resources  Increasing energy efficiency  Improving indoor air quality  Connectivity to community
  • 2. Home Size In 1950 In 1970 297 SF/personaverage floor area 1,000 SF 1.6 x 1950 3.37 people per household 478 SF/person average floor area 1,500 SF In 2000 3.14 people per household 2.8 x 1950 840 SF/person average floor area 2,200 SF 2.62 people per household
  • 3. WASTE GENERATION - millions of tons each year 20% from construction and demolition industry
  • 4. 10% of construction debris is clean unpainted wood
  • 5. RESOURCE USE Construction of a 2,085 sq ft home uses up to 1.5 acres of forest 95% of old growth forests have been depleted
  • 6.  Generation and use of energy (electric, gas, oil, coal) are major contributors to air pollution and global climate change.
  • 7. INDOOR AIR QUALITY We spend 90% of our time indoors Air inside the average home is 10 times more polluted than outside air on the smoggiest days
  • 8.  locally produced, minimally-processed, durable and able to be maintained, low in embodied energy, high in recycled-content, and readily-recyclable.
  • 9.  Fly Ash is a byproduct of coal burning power plants  Use of flyash in concrete diverts it from landfills.  The U.S. produces 1.3 billion tons of Portland cement annually. This emits 1.3 billion tons of CO2 into the environment. Attributes:  Results in a less permeable concrete  More durable  Less shrinkage leads to reduced cracking
  • 10.  Concrete and rubble can be crushed and used for backfill and drainage purposes at the base of foundations Using recycled instead of virgin materials saves money and natural recourses
  • 11. Oriented StrandBoard Laminated Gluelams veneer lumber
  • 12.  FSC certification assures that the forest from which the wood is produced is managed in an environmentally and socially responsible manner
  • 13.  SIPs are high-performance, load bearing panels that consist of a core of foam insulation with OSB on either side. They are generally R-4 per inch
  • 14.  Advanced framing includes many wood saving techniques:  Framing 24” on center  2-stud corners  Stacking trusses over studs  Use single top plates
  • 15.  Builders’ Guide online at www.RECYCLENOW.ORG  Hardware  Lumber  Plumbing  Tile  Windows  Reclaimed wood
  • 16.  Two types of recycled content decking  Plastic lumber  Contains only recycled plastic resins  Check manufacturer for amount of expansion  Composite lumber  Made with recycled wood fiber and recycled plastic resins formed into deck boards Not for use in structural applications
  • 17.  Fiber-cement siding is composed of: Cement, sand, and cellulose Textured to look like wood siding or stucco finish Replaces conventional wood siding or stucco finishes
  • 18.  A green replacement for gypsum drywall, 80% recycled content; Low VOC emissions (meets CA 01350); Highly resistant to mold.
  • 19.  Minimize the amount of fresh water used within buildings and outside for landscaping.
  • 20.  Non Invasive Species No Species Require Shearing Drought-tolerant Natives Minimal Turf Areas Plants Grouped by Water Needs (Hydronizing)
  • 21. Use High-efficiency Irrigation SystemsDrip, Bubblers or Low-flow Sprinklers
  • 22. Water Catchment Filter
  • 23. Rainwater Harvesting
  • 24. Insulate Water Heaters & Pipes
  • 25.  Locate Water Heater within 12 Feet of All Fixtures
  • 26.  Toilets Dual-Flush or maximum 1.6 gpm Showers use max 2.5 gpm Faucets use max 1.5 gpm
  • 27. Energy efficiency is the cornerstone of any green building project.
  • 28.  Direct Gain: Sunlight shines into and warms the living space.
  • 29. Isolated Gain: Sunlight warms another room (sunroom) and convection brings the warmed air into the living space.Sunroom
  • 30.  Plant deciduous trees for shade Natural ventilation is a key cooling strategy Install window overhangs and awnings
  • 31.  COMPACT FLUORESCENT BULBS  Saves up to $120 over the life of the bulb  Lasts up to 10 years  Use Recessed Lighting with CFLs  Insulation Compatible Air-tight (IC-AT) recessed lighting fixtures are sealed
  • 32.  Lighting controls include:  Dimmers  Sensors and timers Install either at specific locations or as a whole house system
  • 33.  Ceiling fans improve interior comfort:  Can be adjusted to either draw warm air upward during the summer or push warm air downward during the winter  Best locations are bedrooms and living rooms
  • 34.  Solar attic fans exhaust heat from attic spaces in summer and clear condensation in winter  Attics can reach up to 150 degrees F.  Heat can migrate into the house
  • 35.  Soffit/eave ventilation and gable/continuous ridge ventilation exhaust excess heat and moisture from attic spaces by natural convection.
  • 36. Whole house fans cool a house without the use of air conditioning  Exhaust warm, indoor air  Bring in fresh, cool, outdoor air at night  Fan mounted in a hallway ceiling on the top floor
  • 37.  Energy efficient refrigerators can use up to 30% less energy Look for Energy Star appliances Check with local utilities for rebates on Energy Star appliances
  • 38.  Exceed the Title 24 Standard for your climate by at least 20%
  • 39.  Avoid damp blown cellulose during wet months The binder reduces the chance of settling. Cellulose is treated to retard insects and fire
  • 40.  Install expanding foam or caulk to prevent infiltration where wood connections are made or framing is drilled to provide plumbing and electrical runs.
  • 41.  Low- E double-glazed windows Low-conductivity frames Look for windows that have a National Fenestration Rating Council (NFRC) label
  • 42.  U-factor  A measure of heat transferred by the entire window (frame, sash, and glass) either into or out of the building. Visible Transmittance (VT)  Select a window with a high VT. Solar Heat Gain Coefficient (SHGC) Air Leakage (AL)
  • 44.  Attached garage is the single most significant contributor to poor indoor air quality (source: U.S. EPA)
  • 45.  Low/no-VOC products are manufactured without:  Mercury or mercury compounds  Pigments of lead, cadmium, chromium or their oxides Low/no-VOC paints are readily available
  • 46.  Conventional solvent-based wood finishes can off-gas for months Low VOC finishes are lower in toxic compounds Can be used in most applications If solvent-based wood finishes must be used, they should be left to off-gas for 3 to 4 weeks prior to occupancy
  • 47.  Low/no-VOC adhesives reduce toxic gasses like aromatic hydrocarbons Can be used for all interior applications  Flooring  Countertops  Wall coverings  Paneling  Tub/shower enclosures
  • 48.  Engineered sheet goods (particleboard, medium density fiberboard (MDF) typically uses adhesives that contain urea formaldehyde Alternative sheet goods include materials made without formaldehyde
  • 49.  Replaces vinyl flooring  Contains petroleum-based products or chlorinated chemicals such as PVC which off gases VOCs  Lasts only 7-10 years Manufactured from natural materials like flax seed, jute, and linseed oil Can last up to 40 years
  • 50.  For slab-on-grade additions or basements Great for radiant, in-floor heating systems Durable and easy to clean
  • 51.  Consumer label, tied to independent field verification Ratings reflect practices ABOVE code in CA Resources for local govt. policies & incentives Quantifies environmental benefits Complementary to LEED for Homes
  • 52. Platinum: 52-69 pointsGold: 39-51 pointsSilver: 33-38 pointsCertified: 26-32 points

  • 54.  Recognizes that each aspect of building design influences others  Envelope affects HVAC sizing  Windows affect lighting loads  Lighting affects cooling loads  Waste heat from one process can be pre-heating for another © Eraxion |
  • 55.  Commit to the integrative design process Hold a charrette Have regular meetings Establish communication protocols Identify scope of responsibilities and interactions for all parties
  • 56.  Identify what aspects of green building are important to your client Talk with your client, subcontractors, and architect about building green Use the Green Point Rated or LEED Guidelines to develop project Ask your local supplier to stock green building materials Get continual training for yourself and your employees Implement green practices into your business
