An inefficient building structure can cause a significant increase in energy expenses for homeowners when regulating the temperature of a building. The more air flows, the more harmful greenhouse gases are released because mechanical systems need extra energy to operate. While a loosely constructed building envelope can create a pleasant ambience, it also results in increased drafts and discomfort due to difficulties in regulating a consistent indoor temperature.

This can improve indoor air quality and eliminate the need for additional mechanical ventilation. Loose building envelopes allow for unregulated air transfer. Classifications of a Building EnvelopeĪ building envelope will often be classified as being either “tight” or “loose” depending on its performance. These characteristics are vital for ensuring that a house meets these criteria.įigure 1: Diagram depicting the process of heat transfer until a thermal equilibrium has been achieved. The last three characteristics have the biggest impact on making a house energy efficient, comfortable, and sustainable. The chosen components will work together to fulfill four essential tasks: providing structural support, managing moisture, regulating temperature, and controlling airflow. This eliminates the need for costly mechanical heating and cooling systems. “īuilding designers are advised to choose the right materials to naturally control heat movement.

It should also include additional materials that act as thermal insulators to prevent heat transfer in both directions. Ideally, a building envelope should primarily consist of materials with very low thermal conductivity values. Materials with a high thermal conductivity value will promote heat transfer and allow heat to quickly pass through them. Thermal conductivity directly relates to the material’s capacity to transfer heat efficiently. The thermal properties of a building material are assessed by determining its thermal conductivity. Thermal properties of a building envelope Each of these materials display unique thermal properties that must be considered when designing the most energy efficient structure.

These materials are arranged in a series of composite layers on a constructional level. The envelope is made up of different materials such as glass, wood, drywall, veneer, and others. Each part plays a role in providing the overall support. These parts can be seen as smaller pieces that work together to support a building’s structure. The building envelope can be broken down into three main parts: the roof, walls, and foundation. It will be able to withstand different climate conditions. A suitable barrier will provide resistance against wind, water, heat, light, and noise. It acts as a barrier between the interior and exterior environments. The building envelope is important in infrastructure design. This strategy aims at maximizing a building’s total energy use.

They are combined into a single design strategy. These components include structural integrity, moisture control, temperature control, and air pressure boundaries. It combines several different components. Technically, building envelope is an engineering system. It also helps maintain a uniform indoor temperature. It offers protection against extreme weather, strong winds, and sun exposure.
