Building Envelope Consulting
High-performance building envelope consulting
As an integrated building envelope consulting practice, we partner with owners, architects, contractors, and manufacturers to deliver high-performance enclosures that are durable, energy-efficient, and tailored to your project goals. The building envelope—including roofing, cladding, glazing, and waterproofing—is one of the most critical and costly components of any structure. It influences energy use, comfort, durability, maintenance, and mechanical sizing.
Early decisions are key to managing risk and achieving long-term performance. Our approach considers every detail, from material selection to system interfaces, helping teams prevent issues like water penetration, air leakage, vapor diffusion, and thermal inefficiencies across climate zones.
With services like energy simulation, condensation risk analysis, and R-value calculations, we provide insights that guide design and construction. Field reviews and performance testing confirm quality, while ISO 9001-certified processes and active research align with ASHRAE and LEED standard recommendations.
Building envelope consulting services
From concept through construction, we design high performance building envelopes and manage risk. We address every aspect of building exteriors—roofing, cladding, glazing, and waterproofing—to deliver durable, energy-efficient enclosures. Services include air barrier consulting, envelope commissioning, energy and component modeling, façade engineering, and thermal bridging. We have expertise in mass timber and design for manufacturing assembly, Passive House strategies, rehabilitation and renovation, waterproofing, and performance.Design innovation
We are committed to advancing the building sciences knowledge base through applied research and innovation. By prioritizing building efficiency, our team pushes the boundaries of building envelope design with next-generation window and external shade strategies inspired by Passive House principles.
