The city council shall consider for inclusion in any solar access ordinance, but not be limited to, standards for:

The placement, height, bulk and orientation of new buildings;


The type and placement of new trees on public street rights of way and other public property; and


Planned uses and densities to conserve energy, facilitate the use of solar energy, or both.


The State Department of Energy shall actively encourage and assist city councils’ efforts to protect and provide for solar access.
