16.18.150 Energy conservation.
All subdivisions shall provide opportunities for passive or natural heating and cooling opportunities to each of the proposed lots, where determined by the reviewing body to be feasible, except for condominium conversion of existing structures where no new structures are added. Such opportunities may include, but are not limited to:
A. Siting of structures or building envelopes to take optimum advantage of passive cooling and heating opportunities.
B. Adjusting building setback lines to promote the optimum spacing of structures to create adequate solar access.
C. Orienting the longest dimension of each lot within thirty degrees of south, unless the subdivider demonstrates that for certain lots:
1. The lots are large enough to allow proper building orientation and maximum feasible control of solar exposure by the lot owner, regardless of lot orientation. Properly oriented building envelopes shall be established for lots smaller than one acre;
2. Buildings will be constructed as part of the subdivision project (as in condominium or planned development) and the buildings themselves will be properly oriented with adequate solar exposure;
3. Topography makes variations from the prescribed orientation desirable to reduce grading or tree removal or to take advantage of a setting which favors early morning or late afternoon exposure, or where topographical conditions make solar energy infeasible;
4. The size of the subdivision in relation to surrounding streets and lots precludes desirable lot orientation. (Ord. 1729 § 4 (Exh. A), 2023)
