Honestly, the definition of open systems is the most confusing of the three types. Open protocols are pretty straight forward — they’re protocols that communicate with one another.

The inaugural AEC BuildTech Conference & Expo is a unique event spotlighting the latest design & building processes, products, and emerging technologies.

Much has been written about systems’ readiness for functional performance testing at the end of construction, and pre-functional checklists have become common elements of the commissioning process.

The Garrett-Jacobs Mansion is a historic, four-story home in the Mount Vernon neighborhood of Baltimore.
