“…Depending on the layout of the building, the spatial environments of buildings containing membrane structures are divided into enclosed and non-enclosed. The effect of indoor height on the temperature in enclosed areas is that, at the same horizontal position, height is positively associated with temperature and its variation range, and the peak time of the temperature curve is delayed as height decreases [105,106]. Nevertheless, thermal stratification is limited as the ventilation system operates [101].…”

“…The interior comfort level of buildings using aerogel materials was upgraded by one level, while the PPD was reduced by 50%, according to the PMV-PPD method. Another study showed that aerogel-glass wool material could effectively attenuate ambient radiant heat and reduce the impact of sunlight on the room regardless of the angle of incidence [106].…”

Lightweight and flexible membranes offer different façades for buildings (suitability, competitive costs, durability, and other benefits) compared to traditional building materials. Increasing attention is being paid to membrane structures in the civil and industrial sectors. Acquiring response data or environmental characteristics directly from a model or building is the most straightforward approach to analyzing the properties of membrane structures, which also contributes to the development of theoretical studies and simulation methods along with the enactment of specifications. This paper provides a comprehensive overview of membrane structure performance, including mechanical, thermal, and energetic aspects, alongside the deployment and deflation of inflatable types. Furthermore, the devices used to monitor the structural response are summarized. The constitution of the structure is the most critical factor affecting its performance. A proper design would offer enhanced mechanical properties and thermal environments with a reduction in energy consumption. Non-contact measurement technology has the advantage of causing no structural disturbance and is low cost, but it lacks practical application in membrane buildings. The achievements and limitations of previous studies are also discussed. Finally, some potential directions for future work are suggested.

“…The optimum aerogel type showed a thermal conductivity of 0.133 W/(m•K). Yin et al [28] investigated the thermal performance of an enclosed dome with a double-layered aerogel-glass insulation system. The investigation was conducted experimentally using thermometers to monitor the temperature during the summertime.…”

Energy consumption, specifically in the building sector, is expected to rise. One potential way to reduce energy consumption, or to slow this increase, is to reduce the heat loss in residential homes. Silica aerogels have grown in popularity as an insulating material due to their extremely low thermal conductivity. However, the benefits of using silica aerogels as an insulator in residential buildings have not been thoroughly studied. To understand the benefits of using silica aerogels as a thermal insulator in residential homes, experimentally validated simulations were performed. The simulations were performed on a model of a full-scale residential house using the multiphysics software ANSYS FLUENT 2019 R2. The simulations helped predict the actual saving benefits of using aerogels as an insulator. Aerogels have the potential to be used as an insulator in both the walls and windows due to its semitransparency. The results showed that the average kWh savings using one half-inch layer of wall aerogel insulation coupled with window aerogel insulation was 20.9% for the single-family house compared to traditional insulation. On average, the energy lost through the windows was 39.1% lower when using aerogel insulation compared to standard insulating materials. The energy lost through the house walls was 13.3% lower on average when using a thin layer of aerogel insulation. While a thin layer of aerogel insulation provided a benefit when used in the house walls, the potential for savings per quantity used was greater in the windows.
