1 Introduction to Green Building

2 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.

5 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.

6 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.

7 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.

8 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.

9 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).

10 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.

11 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.

12 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.

13 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.

14 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.

15 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.

16 Green Certification Programs Many programs certify homes for their greenness in all or some of the above principles, like –ENERGY STAR for HOMES –LEED for HOMES –NAHBGreen –Home Performance with ENERGY STAR They vary based on requirements and verification processes.

17 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.
