ENERGY STAR Qualified Homes
Builder Option Package for Homes
with Solar Hot Water In Hawaii

1.	For more information on HECO's "Energy$olutionsSM for the Home" Solar Hot Water program, please visit:
http://www.heco.com/portal/site/heco/menuitem.508576f78baa14340b4c0610c510b1ca/?vqnextoid=e3d95e658e0fc0
10VqnVCMI 000008119fea9RCRD&vqnextfmt=default.

2.	Cooling equipment shall be sized according to the latest editions of ACCA Manuals J and S, ASHRAE Handbook of
Fundamentals, or an equivalent procedure. Maximum oversizing limit for air conditioners and heat pumps is 15%.
The following operating conditions shall be used in the sizing calculations and verified where reviewed by the utility-
approved inspector:

Outdoor temperatures shall be the 99.0% design temperatures as published in the ASHRAE Handbook of
Fundamentals for the home's location or most representative city for which design temperature data are available.
Note that a higher outdoor air design temperature may be used if it represents prevailing local practice by the HVAC
industry and reflects extreme climate conditions that can be documented with recorded weather data. Indoor
temperatures shall be 75° F for cooling; Infiltration rate shall be selected as "tight", or the equivalent term.

In specifying equipment, the next available size may be used. In addition, indoor and outdoor coils shall be matched in
accordance with ARI standards.

3.	To prevent condensation, using a minimum of R-4 insulation for ducts inside conditioned space is recommended, but
not required.

4.	To ensure consistent exchange of indoor air, whole-house mechanical ventilation is recommended, but not required.

5.	It is recommended, but not required, that insulation be inspected to Grade I installation as defined in the RESNET
Standards.

6.	All windows and skylights must meet the SHGC requirements of this BOP and must either be ENERGY STAR
qualified or meet all specifications for ENERGY STAR qualified windows. Visit www.enerqvstar.gov/windows for more
information on ENERGY STAR qualified windows. Up to 0.75% WFA may be used for decorative glass that does not
meet the requirements of this BOP. For example, a home with total above-grade floor area of 2,000 sq. ft. may have
up to 15 sq. ft. (0.75% of 2,000) of decorative glass.

7.	Any combination of ENERGY STAR qualified products listed may be installed to meet this requirement. ENERGY
STAR qualified ventilation fans include range hood, bathroom, and inline fans. ENERGY STAR qualified lighting
fixtures installed in the following locations shall not be counted: storage rooms (e.g., closets, pantries, sheds), or
garages. Eligible appliances include ENERGY STAR qualified refrigerators, dish washers, and washing machines.
Further efficiency and savings can be achieved by installing ENERGY STAR qualified products, in addition to those
required (e.g., additional lighting, appliances, etc.).

8.	Efficient lighting fixtures represent a significant opportunity for persistent energy savings and a meaningful way to
differentiate ENERGY STAR qualified homes from those meeting minimum code requirements. To learn more about
EPA's Advanced Lighting Package (ALP), refer to www.enerqvstar.gov/homes.
