The Role and Importance of the Building Envelope
The role of the building envelope serves a greater purpose beyond aesthetics; it is key to the performance of the design in terms of energy codes and efficiency.
Because it is the barrier from exterior elements such as rain, wind, and heat, the envelope must be composed of carefully selected materials whether pre-determined (the ones we know work) or a newer type of technology that all comply with building codes and regulations.
Each component of the envelope including the roof, walls, and foundation, faces different challenges in terms of the elements.?It must achieve the important functions of structural support, temperature regulation, airflow, and moisture management. ?The envelope poses a high risk on a project given that its inadequacy can occur in both the design and the installation.
A successful building envelope yields many benefits including minimum energy consumption and cost, visual and acoustic comfort for the inhabitants, and an overall sustainable design.

Building Envelope Technologies
There are several technologies at play when designing the envelope. A pre-fabricated single-source fa?ade system is an example of one of these technologies. The components are manufactured at one facility and pre-assembled, meaning easier installation and only one source of warranty if needed. Along with the easier installation, and reduced risk, there are other positive attributes such as energy efficiency, versatility in appearance, and an increased schedule time.
Another new technology, which is a system we are incorporating into our projects, is a type of “smart frame” composed of T-studs. The T-stud consists of two lumber members with an internal truss system (made from dowels) followed by a poured in place, closed-cell foam. This allows for the consistency of the ambient temperature via a thermal break between interior and exterior elements, and in the long run, reduces the carbon footprint and yields a sustainable building envelope.
