Two broad types of roofs are flat and pitched. One of the primary purposes of a roof is to resist water. There are multiple strategies to defend against weather, namely, barriers, drained screens, and mass storage systems. The control function of a building envelope focuses, on rain control, air control, heat control, and vapor control. Finish functions mean meeting the desired visual aesthetics both on the inside and outside. Control functions include directing the flow of matter and energy of all types. Support functions are to resist and transfer structural and dynamic loads. The many functions of the building envelope fall into three categories: support, control, and finish. Building envelopes keep the conditioned air from escaping the building, cold air from getting inside a heated building, and help to minimize energy waste, while also controlling ventilation and airflow. Climate-controlled buildings need a shell that keeps the elements from affecting the inside air conditioning and heating systems that make interior conditions comfortable and safe. One of the crucial functions of a building envelope is to enable climate control. Building envelopes may also provide some aesthetic appeal with attractive finishes while maintaining the structure’s internal condition. Improving a structure’s envelope helps in protecting the building from the elements, supporting mechanical loads, and keeping the interior safe from outside hazards.

Sage BEC specialise in commercial building envelopes and work with leading manufacturers. TATA Technologies project Contact a SpecialistĪ building envelope specialist can bring a quality experience to a new build or refurbishment project and assess the long-term risks and practicalities of an envelope design. Maximising sunlight with glass and well-sealed energy efficient windows can be significant in design, but regulating the size and orientation in a large commercial premise is essential to balance the flow of heat generated from natural light. The arrangement of windows and doors can have a significant effect on building envelope efficiency. Maximising sunlight in the design by incorporating glazing can also contribute to the reduction of energy consumption. Insulation provides resistance to energy flow thereby reducing the amount of energy required to heat or cool a building throughout the year. InsulationĪdding thermal insulation to a building envelope has proved to be a cost-effective way to reduce energy bills with both new build projects and refurbishments. Therefore, by restricting the passage of air, it is possible to increase the energy efficiency of a building. Natural weather conditions such as strong winds can increase the amount of air that escapes through the envelope, particularly if the envelope and fenestration components are not sealed correctly. VentilationĪ common measure of a quality building envelope is whether it can allow for the ventilation of fresh air whilst protecting the structure from air leakage. The overall construction plays an important role in controlling the levels of light, ventilation and heat flow. Why is The Building Envelope Important?Ī good building envelope design is one of the easiest ways to significantly increase the performance of a commercial building. The envelope includes many components of a building: roof, walls, floors, windows and doors, and quality construction can enhance the architectural design whilst improving the thermal performance of a building. It is one of the most important components in building design due to its role in the maintenance and protection of a structure. A building envelope is t he boundary between the interior and the exterior of a building.
