e e e Mr. Hansen commented that if there is a savings of a $1.5 million per year in Eugene through windows of homes as they now exist, then if we do nothing in existing areas, the savings will continue. He asked if we add regula- tions to existing areas, what the increase of savings will be. Mr. Tumidaj found this very difficult to estimate, but guessed about ten percent in existing developed areas. Ms. Bascom commented that she believed the new solar access regulations were an attempt to add some important amenities to the community and that the regulation of trees had some merit. Mr. Rutan asked for a summary of the major changes in the existing ordi- nance. Mr. Tumidaj replied that the major changes were in the solar setback standards. In the existing code, the standard is 10 a.m. to 3 p.m., and the new regulation has a noon standard, which is more direct. The two other sections of the ordinance, regarding the Solar Design Standards and Solar Access Guarantee, are new. The additions to the code provide more protec- tions; the revisions simplify existing regulations. Mr. Obie asked about accessory buildings such as storage sheds, fences, and signs. Mr. Tumidaj replied that accessory buildings are included in the code, but signs are not addressed in the code. Mr. Reed added that signs are not regulated now, but that there could be isolated problems with signs. Mr. Obie asked what percentage of lots have reasonable solar access available right now. Mr. Tumidaj replied that, in the metropolitan area, 44 percent have solar benefit to south-facing walls and 65 percent have benefit to south rooftops. Mr. Obie then asked what the percentage would be under the ordinance, and Mr Tumidaj replied that the percentage would rise to 80 percent community-wide. This percentage is based on considerable research. Mr. Hansen asked if the ordinance would preclude curved streets and Mr. Tumidaj said no, that subdivisions would still have cul-de-sacs and curved streets because of the 20 percent exemption which allows flexibility in the site design. Mr. Gleason clarified that a $1.5 million savings would be two percent of the base-level cost of the electrical system. The increase in energy sav- Angs projected by the ordinance thus would represent three to five percent of the base cost of the electrical system. ~.
