San Francisco, California, USA, 22 February 2018: The Federal District Court for the Northern District of California on February 15 ruled that the Trump administration must implement four energy-efficiency regulations, including an efficiency standard for commercial package boilers, which it has delayed for more than a year, the Air-conditioning, Heating and Refrigeration Institute (AHRI) revealed.

The US Department of Energy (DoE) wrote the regulations and made them public in December 2016, under the Obama administration, AHRI said. However, when President Trump took office, his administration took advantage of a 45-day window for error corrections to review the rules, AHRI added. The DoE has still not published the rules in the Federal Register, the final step to implementation, but the court has ordered them to be published within 28 days of its ruling, AHRI said. The DoE is reviewing the decision and considering its next move, which may include appeal, AHRI added.

AHRI said it had intervened on behalf of DoE and will continue to discuss the next steps with the administration.
