Greening the building codes - August 2008
The division has approved two
new statewide alternate methods that allow homeowners to harvest rainwater and
reuse wastewater. The first method involves reusing certain wastewater in homes when
the owner installs water conservation systems. The water conservation systems treat
water drained from bathtubs, showers, bathroom sinks, washing machines, and laundry
tubs, and then stores the water for use in flushing toilets. The second method gives
both homes and commercial buildings the ability to collect rainwater from roofs to
be used for gardens, flushing toilets, washing clothes, and in heating and air conditioning
units.
BCD has also been working toward more energy-efficient buildings through upgrading
the energy code provisions (chapter 11) of the 2008
Oregon Residential Specialty Code. The upgrades, which took effect April 1, 2008,
require certain components be put in a building, including new upgrades to building
insulation and an increase in the thermal efficiency rating for windows. Also, there
is a new feature in which builders choose at least one of nine energy efficiency options
to include in the structure.
