Shut the Front Door DC

In 2016, the Council of the District of Columbia amended the law requiring commercial Properties to keep their windows and doors closed when running the air conditioner.

ENFORCEMENT SUSPENDED DURING SUMMER 2020 DUE TO COVID-19

DOES THE LAW APPLY TO ME?

All commercial properties must keep their doors and windows closed when the air conditioning is running. Restaurants are excluded.

WHY IS THIS IMPORTANT?

HVAC systems work harder to achieve and maintain set temperatures when doors and windows are open. During high heat days this can cause high demands on the electrical grid which, when multiplied or concentrated, may lead to brownouts. A brownout causes a reduction in voltage, which can damage your appliances. Lights may go dim and electronic devices - especially computers - can be damaged.
