what is green building
What is green building?

Green building is the process of designing and building a home that minimizes its impact on the environment both during construction and over its useful life.

green home examples
Green Home Examples
  • LEED for Homes Certified Home
  • NAHB Green Certified Home
  • Home Performance with Energy Star Home
  • Many others

What makes these green?

key aspects
Key Aspects
  • Team Approach (Work with Other Trades)
  • Site Selection, Lot Planning, and Preparation
  • House Design and Planning
  • Energy Efficiency
  • Durability and Water Management
  • Water Conservation
  • Green Product Selection
  • Indoor Air Quality
  • Reduce Material Use and Recycle Waste
  • Homeowner Education and Reference Manual
1 team approach
1. Team Approach
  • Teamwork is necessary.
  • Green building requires overcoming challenges in overlaps of work, like between plumbers and carpenters
  • There will be a learning curve that you go up quickly with just a few projects.
2 site selection lot planning and preparation
2. Site Selection, Lot Planning, and Preparation
  • Though not relevant to construction trades, all should know about basics in site and lot selections.
  • Sites that decrease environmental impact (like not building on wetlands) are preferred.
  • Sites that do not increase urban sprawl are better.
3 house design and planning
3. House Design and Planning
  • Homes with smaller footprints generally use less materials and later, less energy.
  • Constructing efficient homes reduces waste.
  • Good communication and information between all of the new construction trades overcomes design problems during construction.
4 energy efficiency
4. Energy Efficiency
  • A green home is well-framed and insulated and as airtight as possible.
  • The windows and doors are selected for energy-efficient glazing and air seals.
  • Energy-efficient HVAC, lighting and appliances are selected.
  • So, carpenters, HVAC technicians, electricians, and FM technicians are especially important.
5 best construction practices weather resistance durability water management
5. Best Construction Practices (Weather Resistance, Durability, & Water Management)
  • Many good practices are green, but especially ones that create quality construction.
  • Durability and water management issues are focuses of trades that deal with structural materials (like carpenters and masons) as well as those trades that deal with the long-term performance (FM technicians).
6 water conservation
6. Water Conservation
  • Green homes require less water.
  • The plumbing system is designed with water efficient fixtures.
  • Native drought-resistant plants and reducing lawn area reduce irrigation.
  • Innovative systems such as rainwater collection and gray water reuse reduce external water need.
  • Plumbers and FM technicians play key roles.
7 green product selection
7. Green Product Selection
  • Several qualities of materials and products determine whether they are green, like:
    • Did it come from recycled materials?
    • Can the material be recycled in the future?
    • Was it made locally?
    • Did it use low energy and water to manufacture it?
  • While all trades can make green selections, carpenters play a special role because of the amount of materials and products they use.
8 indoor air quality
8. Indoor Air Quality
  • Several things can affect indoor air:
    • Mold and moisture
    • Radon
    • Lead and other hazards
    • Formaldehyde and Volatile Organic Compounds (VOCs)
    • Ventilation
  • The team of HVAC technician, carpenter, and FM technician play important roles.
9 reduce material use and manage waste
9. Reduce Material Use and Manage Waste
  • Materials can be planned, estimated, ordered and installed accurately to reduce total amount of use and waste.
  • When leftover, materials should be recycled or reused.
  • The two structural trades (masons and carpenters) that use the largest quantity of materials play key roles.
10 homeowner education and training manual
10. Homeowner Education and Training Manual
  • A green home won’t perform well if it is not operated and maintained as designed.
  • All trades must provide information, but the FM technicians play a key role in making sure that occupants understand it and follow through with it.
current state of green building
Current State of Green Building
  • Many long-proven technologies are ready to be incorporated.
  • Many new materials and products are still coming out.
  • A majority of builders are familiar with green building, and a good portion are already using them.
green certification programs
Green Certification Programs
  • Many programs certify homes for their greenness in all or some of the above principles, like
    • LEED for HOMES
    • NAHBGreen
    • Home Performance with ENERGY STAR
  • They vary based on requirements and verification processes.
future of green building
Future of Green Building
  • New materials and technologies are coming out every year.
  • Green certification programs change requirements on a regular basis, just like building codes.
  • A majority of builders are expected to be using green building techniques within 5 years.
