Green 200: The Science of Green Building
Green 200: The Science of Green Building
Course Goals
2
Learning Objectives1. Green Home Design
How professionals make choices and work together
2. Green Home Construction—The Building Envelope Moving design choices from the
drawing table to the site
3. Green Home Construction—Systems Green systems inside the home
4. Power Off the Grid Generating electricity off the grid
5. Greening Existing Homes Retrofitting, remodeling, and
renovating existing homes

Green Home DesignGreen Home Design1
3 Reasons for Green
1. Health and indoor air quality concerns
2. Energy efficiency
3. Environmental concerns consumers are willing
to reward or penalize a company based on its green actions and priorities.
6
Green Design, Green Choices
Four phases
7
Site Selection
Traditional building Starts with the design
of the home
Less consideration for the site
Green building Starts with
assessment of the site
Create a structure that integrates into the environment
Proximity to transportation and walkability to amenities
7-10
Site SelectionGreen building; consider
seasonal impacts of the site: Location—transportation and
walkability Greenfield, greyfield, or brownfield? Sunlight patterns Prevailing winds Storm water runoff and snow
accumulation patterns Natural features such as hills and
trees Climate and microclimates Ecosystems, wildlife habitats and
corridors, wetlands

Home Design
Green building, “functional” and “compact”
Small homes cost less to build and
maintain use less material feel cozy and sheltering
Large homes contribute to sprawl require more materials consume more energy
Tip: Homeowners should make a list of all activities to assure home will meet their needs.
11
Home Design Checklist
Layout and size Minimize solar heat gain Maximize natural lighting Framing Building codes and zoning Incentives Landscaping Water management Energy efficiency Recycling Certifications Future marketability Architectural appeal
12
Building Materials Reclaimed sawdust in
composite floorings Bamboo in decorative
veneers Shredded paper and
cardboard in waterproof building sheathing
Recycled glass in countertops and flooring
Crushed seashells in decorative tiles
Tip: Refer to Green 100 for a list of material certifying organizations.
14
Embodied Energy
the sum of all energy inputs over the lifetime of materials
14
Low Toxicity
Green construction materials minimize or eliminate emissions from: Paint and adhesives Carpet Cabinetry Wall board Wall coverings Pressure treated lumber
15
Pressure Treated Lumber
Purposes: to retard rotting and repel pests.
Chromated copper arsenate (CCA)• May be present in older
buildings .
• Requires special handling for disposal.
• Burning CCA emits arsenic.
Copper-based preservatives (arsenic-free)
16
Managing Construction Waste
2,000 sq ft home = up to 8,000 lbs of waste
Most waste Wood
Cardboard
Drywall
Green construction plan: Efficient cuts
Minimal or recycled packaging
Deconstruction instead of demolition
16
Interior SystemsInterrelationships
Balance; site with building orientation, ventilation with air quality and moisture control, HVAC with insulation.
Sound and Light Balance privacy, natural lighting,
ventilation, connection with nature, interior heating or cooling, and quiet spaces.
Indoor Climate Balance livability with sustainability and
energy-efficiency.
19-21
Interior Systems
Water Management Conserving, harvesting and heating
Energy Load Energy modeling estimates energy
consumed in BTUs, dollars, or pollution avoidance as a result of design and system choices.
On Site Energy Generation Home design systems for generating and
storing, or selling back, electricity.
