Critical Factors
Top architecture needs to encapsulate a design that achieves uniqueness, innovation, appeal, and is descriptive, meanwhile achieving project-specific performance requirements. Building facades are a critical element in managing workplace productivity along with energy efficiency. While natural daylighting helps promote a more productive work environment, if the proper façade systems are not chosen, it can wreak havoc on a mechanical system, significantly increasing energy usage and therefore building costs. TSI’s team will work with the design team to balance design, performance, and cost of the building envelope system.
To achieve this optimal balance, our team provides comprehensive guidance and expertise by meticulously managing 9 key critical factors:
