Services
Building Envelope Consulting
Our building envelope consulting services ensure durable, code-compliant building enclosures. We provide design review, construction administration, and forensic investigation for commercial and residential projects. Our licensed engineers create detailed drawings and specifications while coordinating with design teams to prevent water intrusion and air leakage. Clients benefit from our 25+ years of experience in weatherization and air barrier systems.
Building Energy Modeling
We offer comprehensive energy modeling services using industry-standard software to optimize building performance. Our models predict energy consumption, support code compliance, and identify cost-saving opportunities. Services include thermal envelope analysis, air barrier design, and hygrothermal modeling to prevent moisture-related issues. Our Washington state-approved energy modeling helps achieve certifications like Energy Star and LEED.
Building Envelope Testing
Our AAMA-accredited testing services verify building envelope performance through window water testing, air barrier diagnostics, and electronic leak detection. We conduct field testing according to ASTM standards and provide quality assurance for new construction and remediation projects. Our certified technicians use thermal imaging and specialized equipment to identify and resolve performance issues.
NFRC Simulations
As an NFRC-accredited laboratory, we provide thermal performance ratings for windows, doors, and skylights. Our simulations determine U-factors, solar heat gain coefficients, and condensation resistance values to support code compliance and energy programs. We serve manufacturers needing product certification and builders requiring project-specific ratings using CMAST software.
Remediation Consultation
We help property managers and HOAs address water intrusion issues through comprehensive assessments and maintenance planning. Our services include infrared thermography, leak investigation, and reserve study reviews. We develop tailored remediation strategies and preventive maintenance schedules to extend building lifespan while minimizing repair costs.
