How are Healthy and Buildings linked?

D i i d t d h l l ti

Buildings have INERTIA!

• Decisions made today have long lasting effects into the future.

• How are Healthy and Buildings linked?– People [social justice]– Builder and owner Financial Health [economic justice]– And the continued flourishing of the natural Environment to g

support People [environmental justice]• The building industry is the largest industry

consumer of the world’s resources, consuming 36% of the world’s energy usage– (Energy Information Administration www.eia.doe.gov)

Research-Planethttp://www.eia.doe.gov/oiaf/1605/flash/flash.html

What is Green Building?• Green Building is• Green Building is…

• Consideration of the building as a whole system from:

– Conception– through design and construction– for the duration of the life of the building

I t ti f h d d d i i t• Integration of human needs and desires into a healthy whole system that supports and sustains the requirements of a healthy natural environment

• Focused on Transforming the Market

Considers the interactive effects

Recognizes that components of the building l k d h

are linked together

All components must be considered at the same time

This creates a cost-effective whole building solution

…and it can be more difficult to accomplish in an existing building than in a new one

To Transform the Market…

• We need to change the process, not just the technology– The Design Process– The Construction Process– The Marketing Process

Green Building Programs seek to Transform the Building Market

Non-Profit Eligibility?

• SB 3 of 2007 amended North Carolina's renewable energy tax credit statute to allow a taxpayer who donates money to a tax-exempt nonprofit to help fund a renewable energy project to claim a tax credit. The donor can claim a share of the credit -- proportional to the project costs donated -- that the nonprofit could claim if the organization were subject to tax HB 2436 of 2008 applied this same mechanism totax. HB 2436 of 2008 applied this same mechanism to donations made to units of state and local governments.

Policy and Green Buildings in NC 8/2009• Net Metering: Although NC has Net Metering, there are a few issues including:

REC Treatment [Utility gets RECs if customer is not on a TOU rate]

Treatment of net excess generation

According to “Freeing the Grid”, 2008

Treatment of net excess generation [monthly rollover, but granted to utility at beginning of summer billing season]

Only Investor-owned utilities are required to provide [no munis or co-ops]

• Interconnection: NC’s Interconnection standards are more evolved. Suggested improvements:

Prohibit additional insurance requirements

Prohibit redundant disconnect switching

Expand to all utilities
