On April 18th, The Building Enclosure Council (BEC) of Indiana hosted a breakfast seminar to discuss the newly founded organization and also to discuss the risks and perspectives of the building envelope as well as a few case studies. This was the inaugural event for BEC Indiana and over 75 individuals representing a diverse group of owners and construction professionals attended. The following are 9 key takeaways from the seminar:
- BEC – Indiana was founded for everyone in the Indiana market with the goal of improving the design and construction of buildings in our region.
- Risks related to the building enclosure include water leakage, air leakage, condensation, energy usage, falling debris, and fire.
- Everyone from the owner to designers and general contractors to material suppliers bear responsibility and risk in the successful performance of the building enclosure.
- Somewhere between 65% and 80% of all post-construction claims are related to the building enclosure system. (“How Buildings Learn” by Stewart Brand and Architectural and Engineering Performance Information Center (AEPIC))
- As much as 90% of all water intrusion through a building enclosure occurs within 1% of the total building enclosure area. (Construction Waterproofing Handbook, M. Kubal)
- The $187,000 Rule – Catching and fixing problems in the design phase can cost thousands of times less than if the problem were litigated after construction.
- There are many perspectives and roles in the design, construction, and maintenance of the building enclosure. It is a theoretical question to ask who has the most influence and responsibility for implementing successful building enclosures. The reality is that every project team member has the power and responsibility to care for the building enclosure.
- Case studies presented showed that building enclosure issues can be related to factors including design, installation, and maintenance.
- Vapor Barriers in Roofing – In the Indiana market, vapor barriers should be considered and study on a case by case basis. Factors that influence the need for vapor barriers in roofing include the interior conditioning and use of the building and the type of roofing system utilized. There is no one size fits all opinion for the use of the vapor barrier in the Indiana market. However, generally, the use of vapor barriers in the roofing system in the Indiana market will reduce the risk of roofing performance issues.
