RTM Engineering Consultants hosted its fourth broadcast in a series aimed at educating the architecture and commercial real estate community on new engineering processes and best practices. This month’s session focused on the design and insulation of building envelopes.
Known as what separates the interior and exterior of a structure, the building envelope can greatly impact the performance and efficiency of a building’s systems. Because of this, proper building envelope design is key in ensuring the exterior climate is separated from the interior temperature and humidity-controlled climate. This session sought to help listeners understand how and where best to insulate a building to avoid humidity concerns, while improving the building’s energy efficiency.
With more than 10 years of designing mechanical systems for new construction and renovation projects, presenter Dale Adney, P.E. was able to pull from years of experience as he led the webinar. Some of the topics covered included:
- The most significant types of envelopes, which are building envelope and thermal envelope, and how the two stack up against one another
- Defining and distinguishing the difference between vapor barrier and vapor retarder
- Building air balance and pressure – how to maintain a neutral or slightly positive pressure
- How to calculate building ventilation
- Signs of envelope design issues resulting in humidity problems within the building
- Where to place your air barrier and the specs when constructing it
- Answering the questions: ‘How do I know how much insulation is best for a building?’ and ‘Where is it best to insulate a roof?’
