“…Many studies are conducted to estimate the heat transmission loss through the building walls and roof using dynamic heat transmission (Daouas, 2011; Feng et al, 2019; Ozel, 2019; Ramin et al, 2016; Saafi and Daouas, 2018), experimental (Cuce et al, 2014), and degree-day/hour methods (Alsayed and Tayeh, 2019; Feng et al, 2019; Huang et al, 2019; Küçüktopcu and Cemek, 2018; Vincelas et al, 2017; Yuan et al, 2017a, 2017b), which are fed in life-cycle cost (LCC) analysis to determine the optimum insulation thickness corresponding to maximum cost savings (sum of insulation cost and operation cost). For instance, the dynamic heat transfer and the LCC analysis were conducted by Daouas (2011) to calculate optimum insulation thickness for single-layered brick wall considering different orientation.…”

Heat transfer through building opaque envelope is responsible for approximately half of the total heat loss and gain to and from the surroundings. Therefore, insulation materials are commonly used in the building envelope to reduce the heat transfer. Recently, lightweight wall materials with lower thermal conductivity are used in construction along with the commonly used materials such as heavy concrete and earthen materials. In this perspective, there is a need to understand the optimum insulation thickness for different types of building construction materials to minimize unnecessary usage of insulation materials. This study investigated the optimum insulation thickness for different construction materials following a life-cycle approach, where an analytical optimization methodology based on the degree-days method and life-cycle cost analysis was used. In total, 4 insulation materials and 15 building construction materials were considered in the optimization study. The objective function was to minimize life-cycle cost corresponding to the decision variables including insulation thickness and the thermal conductivity of insulation and wall materials. The results showed that the use of insulation in lightweight wall materials is not economically feasible because of their negligible cost-saving potential (below US$2.5/m2-year). However, the walls with heavy concrete and earthen materials that have high thermal mass must be insulated due to their highest cost-saving potential (US$14–26.39/m2-year).

“…Moreover, it was found that the lowest insulation thickness was natural gas in Antalya and the insulation material was 11.20 cm by XPS. Maximum energy saving value was found as 70.61% in Erzurum with the LPG and the EPS insulation material . In this study, the contraction effect of the air‐ducts insulation was investigated in the HVAC system in a company.…”

Energy is one of the most fundamental event of the universe and it is impossible to imagine an area where energy is not used. The energy demand is also increasing with the ever‐increasing population of the world. We also use energy to meet our heating and cooling needs. Heat loss from the exterior walls of buildings is important, so thermal insulation on the wall is very critical. In this study, optimum insulation thickness is determined for four provinces and two different insulation materials selected from four different climatic regions of Turkey. In order to calculate insulation thicknesses, the number of the degree‐day and exergetic environmental impact factor have been used. Natural gas is used as fuel. By using exergetic life cycle cost assessment method for rock wool and glass wool as insulation materials, the changes of CO2 emission values, the environmental impact factor, and energy saving values are determined for optimum insulation thickness. The optimum insulation thickness, which are calculated by using the number of the degree‐day and exergetic environmental impact factor for glass wool and rock wool is 0.1103 m and 0.04375 m for Antalya, 0.1667 m and 0.07292 m for Isparta, 0.1667 m and 0.0625 m for Bursa, and 0.2188 m and 0.1021 m for Erzurum, respectively. The reduction of carbon dioxide emission values for glass wool and rock wool 86% and 64% for Antalya, 90% and 76% for Isparta, 92% and 82% for Erzurum, and 90% and 73% for Bursa, respectively. Net exergetic environmental impact saving values for glass wool and rock wool: 589 mPts/m2‐yr and 342 mPts/m2‐yr for Antalya, 1,318 mPts/m2‐yr and 642 mPts/m2‐yr for Bursa, 1,315 mPts/m2‐yr and 878 mPts/m2‐yr for Erzurum, and 2,248 mPts/m2‐yr and 1,687 mPts/m2‐yr for Isparta, respectively.

“…However, there are obvious defects in the traditional thermal insulation materials. For instance, organic insulation materials are easy to burn and release toxic fumes when they burn, while inorganic insulation materials have high density and cost . In addition, the traditional insulation materials system with supporting elements usually cause problems such as cracking and point thermal bridge .…”

Summary In hot climate, phase change material (PCM) can be incorporated into building envelopes to reduce heat gain through the building envelopes and therefore reduce its cooling demand. In this study, the energy performance of building envelopes integrated with PCM has been explored using a popular dynamic building performance simulation package, EnergyPlus, and the energy saving mechanism of PCM was investigated. The simulation results reflected that PCM could effectively help to reduce the building's annual energy consumption by 20.9% for Guangzhou, China. In addition, for the Guangzhou city, 27°C transition temperature, smaller thermal conductivity of roof, and higher amount of PCM can all help to improve the building's energy performance. Additionally, it is suggested that in real building development/retrofit projects, the selection of PCM needs to be based on both their thermal properties and the local climatic conditions of the building.
