“…Energy analysis taking real-time data and simulating it in the 3D environment is widely utilised in building design and retrofit contexts for energy calculations, environmental impacts and occupants' requirements (Wu and Liu, 2020). Meanwhile, according to Liu et al (2019), there is no simple system to describe information content requirements, specification for thermal comfort management practices and information exchanges in construction projects. The integration of thermal comfort parameter information deliveries into a project plan contents of unclear understanding methods of energy efficiency and indoor wellbeing technologies, for instance, control systems, lighting, ventilation, thermal storage and heat recovery, which include temperature differences between indoors and outdoors, building envelope and the efficiency of heating and cooling equipment for thermal industry standardisation (Galagoda et al , 2018; Kwong et al , 2020).…”

PurposeImproper evaluation and information mismanagement concerning thermal comfort appears to negatively affect occupants' satisfaction and building energy consumption in precast concrete (PC) building contexts. Predictive models are particularly problematic in PC building construction projects where natural ventilation levels do not coincide with occupants' thermal comfort and thermal sensation specifications.Design/methodology/approachA systematic literature review is undertaken to explore the viability and benefits of a new ICT-based approach for meeting social and environmental objectives.FindingsSophisticated thermal comfort system solutions are essential for optimising thermal comfort and saving energy in PC building construction projects.Originality/valueIt is imperative that designers and manufacturers are kept up-to-date with the possibilities and potentials associated with new and nascent technologies so that building projects can meet key sustainability criteria.

“…Totally, 6 room heaters are associated in series to control power system which is utilized as a heat source to heat one face of the selected specimen. Thermocouples were connected by sticky tape onto the zone on which the heat was connected [27][28][29][30][31][32]. Experimental setup had all out nine thermocouples and three advanced multimeter for presentation.…”

Construction of housing with levels of popularity on energy saving is the most significant tasks. Lessening the thermal raise during the rooftop and divider boards is the most ideal advance to manage declining energy usage and to giving thermal help to the customers of private or business structures. Thermal insulation of buildings assumes a vital function in upgrading the comfort level of tenants by lessening the temperature of the building. In this investigation, we focused to reduce the thermal qualities in building by protecting polystyrene material in roof ceilings and wall panels. Here, we investigate the temperature among two climatic conditions i.e. summer and winter. The temperature is noted for 3 hours with 10 minutes interval for totally 40 specimens. Different types of specimens are used i.e. Reinforced Cement concrete (RCC) and Fiber Reinforced Concrete (FRC) specimens based on treated and untreated with insulating materials. The experimental results are validated by using training based Optimal Neural Network (ONN); here the ONN structure is trained with the help of Levenberg- Marquardt (LM) algorithm. The optimization predicted temperature for each specimen with Minimum Error Rate (MSE) compared to existing approaches.

“…This shortcoming has limited the applications of glass, especially in privacy protection, smart windows, and energy conservation. Recently, intelligent glass such as glass with shutters, [ 6 ] photothermal responsive glass, [ 7,8 ] thermo‐responsive liquid glass, [ 9 ] electrochromic glass, [ 10–12 ] and liquid crystal switchable glass [ 13,14 ] has received widespread attention due to the high market demands in smart living. Most of this glass is able to regulate the light transmittance between transparency and opacity by an external stimulus.…”

Glass is widely applied in fields of architecture, automobiles, optics and instruments due to its light transmission, wind resistance, sound and heat insulation. However, the light transmittance of traditional glass cannot change after the glass is formed, which limits the practicability of glass. In this study, an intelligent glass that can quickly and freely switch between transparency and opacity based on an optical‐thermal responsive hydrated poly(N‐isopropylacrylamide) film triggered by white light, infrared light, and direct thermal stimuli is developed. The fastest response time is ≈21 s under white light or 5 s by hand touch. A fatigue test of 250 cycles showed no obvious performance degradation. The transmittance of the intelligent glass changed reversibly between 88.5%–93.2% (transparent) and 25.5%–41.6% (opaque). The optical‐thermal response of the intelligent glass is attributed to the reversible phase transition of the hydrated poly(N‐isopropylacrylamide) film. This intelligent glass not only has obvious advantages in energy savings and emission reduction but also may be very useful for privacy protection, for example, in car windows, house windows, and office windows.
