A final inspection for a building permit subject to the requirements of this chapter shall not be approved unless the work authorized by the building permit has been constructed in accordance with the approved plans, conditions of approvals, and requirements of this chapter.
(Ord. 10-06 § 3)
In addition to meeting all requirements of 2008 Building Energy Efficiency Standards, all applications for building permits that include buildings or improvements covered by this chapter shall include the following mandatory energy efficiency measures as may be applicable to the proposed building or improvement:
A. 
Residential Buildings. Any built-in appliance (excluding HVAC equipment and water heaters) to be installed in a residential building shall be Energy Star rated, if the appliance installed is of a type that is Energy Star rated and the appliance is not listed with minimum efficiency requirements in the latest edition of the National Appliance Energy Conservation Act (NAECA.)
B. 
Swimming Pool and Spa Heater Pumps. Any circulation pump to be installed for any swimming pool, spa, or water feature for which a permit is required by this Code shall incorporate the following energy conservation feature:
1. 
All circulating pump motors and filtration pump motors with a nominal rating of 0.75 horsepower or greater (except pump motors only serving spa jets) shall be two-speed or variable speed motors. The installation of all two-speed and variable speed motors shall include the installation of a controller which shall be time-based and shall be programmed to alternate the speed of the motor between low and high to make effective use of the energy savings potential of the unit’s multi-speed capability.
(Ord. 10-06 § 3)
In addition to any applicable mandatory requirements specified in Section 22.82.050 and the requirements of the 2008 Building Energy Efficiency Standards, the following general compliance requirements shall apply to permit applications subject to this chapter as follows:
A. 
Residential. Applications for building permits that involve new residential buildings or additions to existing residential buildings where the additions are greater than 500 square feet of conditioned floor area shall demonstrate compliance with the general compliance requirements as follows:
1. 
New Residential Buildings. When an application for a building permit involves a new residential building, the performance approach specified in Section 151 of the 2008 Building Energy Efficiency Standards must be used to demonstrate that the TDV energy of the proposed building is at least 15.0% less than the TDV energy of the standard building.
2. 
Additions to Residential Buildings. When an application for a building permit involves an addition to an existing residential building, this general compliance requirement may be met by either of the following methods:
a. 
Using the performance approach specified in Section 151 of the 2008 Building Energy Efficiency Standards to demonstrate that the TDV energy of the proposed addition is at least 15.0% less than the TDV energy of the standard design; or
b. 
Using the “Existing + Addition + Alteration” calculation methodology to demonstrate that the TDV energy of the proposed building is at least 15.0% less than the TDV energy of the standard design, as calculated in accordance with the performance approach specified in Section 151 of the 2008 Building Energy Efficiency Standards. In modeling buildings under the Existing + Addition + Alteration method, domestic hot water energy use must be included in the calculation model unless the application does not involve a change to the building’s existing water heater(s).
B.
