Building code requirements for new homes are constantly evolving, and as of late, Maryland Energy Code requires all new homes in Maryland to adhere to specific guidelines that ensure better energy efficiency and indoor comfort. If you’re building a new home in Maryland, it’s important to make sure your new home will be Maryland Energy Code compliant. York Home Performance is here to help.

Maryland Energy Code: What You Need to Know

When it comes to new home construction, Maryland enforces the 2012 International Energy Conservation Code (IECC). This code impacts many parts of your home which contribute to overall home efficiency, including lighting, windows and doors, insulation, air sealing, and heating and cooling equipment.

In order for your new home to be considered “code compliant,” it must demonstrate a minimum level of efficiency in various areas, including airtightness.

Blower Door Testing for Measuring Airtightness

Airtightness is measured through something called a blower door test. During a blower door test, a home performance expert installs a very powerful fan in an exterior door frame. This fan then blows inside air outside, lowering the air pressure inside the home. The lower indoor pressure causes outside air to seep in through any and all air leaks in the home’s exterior. This gives your home performance expert the opportunity to measure your home’s overall air leakage and pinpoint exactly where these air leaks in your home’s exterior are.
