All of the councils records are online.This is an excerpt from a communication back in 2007.What is not to understand here ?
There are dozens of records of meetings about changing the code.
What was the council doing during all these meetings and presentations ?
PURPOSE OF RESIDENTIAL CODE
1. Lower monthly utility bills fox the homeowner over the life of the home;
2. Reduce electricity growth rates and stress on the electricity grid;
3. Reduce County dependency on imported fossil fuel.
EXISTING RESIDENTIAL CODE
Hawaii County's existing energy code has not been updated since 1994. The current code requires homes designed for central air conditioning have R-19 insulation in the roof and R -11 in the walls. No codes exist for homes designed without air conditioning or designed for window-unit air conditioners.
The "R" stands fox resistance to heat transfer. The higher the number, the greater the resistance of the structure to allow the sun's heat to transfer from the outside to the home's interior.
PROPOSED RESIDENTIAL CODE
The proposed code will apply to all new homes and deal with the roof, walls and windows. The reason for applying to all homes is that many homes axe uncomfortably hot because they are inadequately insulated and allow the sun to heat the interior to over 90 degrees on hot days. Homes complying with the proposed code will be at least eight
degrees, and in some cases, 12 degrees cooler than an uninsulated home. The reduced temperature often negates the need for air conditioning. If conditioning is needed, a smaller unit can be purchased at a considerably lower price.
In the roof, the proposed code would allow not only conventional fiberglass or foam insulation, but the use of radiant barriers, cool roofs and solar fans as means of keeping the attic, and hence the interior naturally cool. Each of these methods is extremely
affordable. The counties of Honolulu and Maui have this roof code in place.
R-11 would be required in the walls, with credit given fox reflective exterior coatings.
This option offers more flexibility in R-11.
Windows would have a minimum 0.40 solar heat gain.coefficient. This means that only 40% (or less) of the sun's heat striking a window would penetrate through the window.
A standard single-pane window allows about 90% of the heat through, creating a greenhouse effect in the home. This high-performance glass is now the industry standard by all manufacturers, making the price cost-competitive with the older types of window glass.
