4.12   Minimization of high energy use (Incandescent ) lighting.

4.13   Building design and orientation does not require air conditioning.

4.14   Air Conditioned Buildings.
Air Conditioned buildings should be Energy Star compliant.

4.14.1  *Air Conditioned buildings are sealed and the roof is well insulated.

4.14.2   *Building has an Energy Star approved energy efficient AC system. (Submission required describing system including  Mfg. name & Model #’s.

4.14.3   *Air-conditioned buildings windows and doors are Energy Star approved
or equivalent ENERGY STAR Qualified Windows, Doors and Skylights Eligibility  To be eligible for the ENERGY STAR, products must be rated, certified, and labeled for both U-Factor and Solar Heat Gain Coefficient (SHGC) in accordance with the procedures of the National Fenestration Rating Council (NFRC) |  at levels which meet ENERGY STAR qualification criteria in the Southern Climate Zone.

8.7     Fruit trees are planted on the property.

8.8     A organic vegetable garden is on the property
