Energy use by swimming pools, spas, and other exterior equipment requiring a building permit such as snow and ice melt systems, and similar outdoor features, must be offset by on-site renewable energy generation equivalent to the energy used. All spas must have an insulated cover.
Exception: Swimming pools equipped with all of the following equipment do not need to offset their energy use by on-site renewable energy sources: solar thermal heating systems (without the use of fossil fuels), high-efficiency two-speed or multi-speed pumps, cartridge filter systems, and an automatic cover.
