Resident-builder warns commission that some energy-code requirements could raise construction costs

Charles Mueller, a Ridgeway resident who identified himself as an experienced builder, told the commission the proposed energy-code amendments contain provisions that could substantially increase construction costs for certain building types. "Every time you add another layer of these requirements, it adds cost," he said during public comment, and he cautioned that high-thermal-mass construction (concrete walls, radiant flooring) presents different design trade-offs than typical light-frame houses.
