Project Modeling and Details Improved Energy modeling reliability along with required calibration and •with BECx review more accurately predicts functional performance of Thermal, Hygrothermal Analysis and Thermal Bridging of systemsBECx• review looks at continuity details to verify that thermal bridging and air leakage are eliminated. Isometric drawings will more accurately identify disconnects. •

Extreme Weather conditions should be modeled at this phase including adhesives and sealants performance

BECx design phase involves drawing and spec review

Construction Latent Defects

Defects that are concealed and are often not obvious or readily observable upon reasonable inspection

Improper through-wall detailing and installationCaulking is deficient

Building Enclosure Commissioning - BECx

Intended to assure building quality by establishing an explicit process to verify that a building enclosure is designed and constructed

to meet the owner’s objectives

ASTM E• 2813-12, Standard Practice for Building Enclosure CommissioningSpecification section Division • 01 Functional Performance Testing supersedes testing specified in Divisions 07 and 08 on individual product testing and compliance of performance

Functional performance testing cannot just specify what tests are run, •they must specify what constitutes passing or failing

BECxA (authority)ASTM • E2813, requires knowledge of core competencies including:Exterior • façade designBuilding/Material science and physics•

Adhesives & Sealants •Procurement • and project deliveryContract • documents and construction administrationPerformance • test standards and methodology

Building Enclosure Performance MetricsEstablished during the design phase•

Performance assessment and testing typically include• :Preconstruction laboratory mockups•Field• -constructed mockups, both off-structure and on-structureField testing at milestone intervals•Post• -occupancy evaluation

Adhesives & Sealants are the Integrators of systems and components

Integration of systems and components

Adhesives and Sealants are found in many construction assemblies that require specific specification per the integration function

Off-Site Construction Assemblies vs. Site-Built Construction

Potential Benefits of Off• -Site Manufactured Systems and Assemblies

Specifically Skilled Labor in controlled factory environment•Latent Construction Defects associated with Site Built Systems•Consistent Quality Control•Reduces potential for construction defects•

Site• -Built ConstructionTypically utilizes multiple trades for installation of components for the assembly on site•60• % of AGC contractors report not enough skilled laborMore likely to incur higher amount of latent construction defects between materials•
