Fight over Colorado and Denver building energy standards gains federal attention

The federal government is scrutinizing Colorado and Denver's building energy standards, signaling a potential legal clash over state versus federal authority. The Department of Justice is considering filing a Statement of Interest in a lawsuit that questions whether these local regulations preempt federal laws like the Energy Policy and Conservation Act. This move underscores a broader debate about state innovation in environmental regulations versus federal oversight, with significant implications for future energy policy and construction practices nationwide.
