“…Using the MMG+_KU Leuven tool, this research has been conducted to address the environmental impacts for several modules, including glazing, coatings, window frame material, and window-to-wall ratio. For windows retrofitting in heritage buildings to reduce the operating energysaving, Litti et al [13] have used the LCA method to discuss the difference between retrofitting alternatives for the windows to total replacement. For Italian residential windows, Intini et al [14] have studied the LCA of the polyvinyl chloride (PVC) windows using the SimaPro software and Ecoinvent database.…”

The main goal of this study is to undertake the three methods of life cycle assessment (LCA), the environmental performance (EP), and the building information modeling (BIM) to determine the environmental performance and impacts of two window frame materials: aluminum and wood. This study has been carried out in a proposed project at the Assiut University campus. The LCA has been conducted by assessing materials and processes involved in manufacturing the two window frame types using the SimaPro. The LCA scope of this research covers from cradle to the gate with a designated system boundary. The network flow has been drawn to produce one kilogram of aluminum and wood; the quantities data were gathered from the BIM (using Autodesk Revit). Selecting the database is carefully picked from the Ecoinvent dataset to be closer to Egypt's manufacturing processes. Afterwards, the IMPACT 2002+ with midpoint and endpoint calculations has been used. Finally, the LCA results have been compared with the EP results (using DesignBuilder) to determine the best choice between the two materials. The integration analysis shows that the aluminum industry has higher negative environmental impacts and environmental performance than the wood industry. The total midpoint results of the two materials are found to be 29.6 for aluminum, and 2

“…Also, Litti et al [34] investigated the replacement of historical windows with new ones as an additional measure to improve thermal insulation. The findings highlight that replacing windows does not necessarily allow for the largest energy savings over their full life-cycles, while their maintenance may result in comparable or more considerable savings [34]. In fact, the LCA methodology can be used to select solutions or materials using less energy and thus emitting less CO 2 , however, the application of the LCA methodology is still in its infancy in the cultural heritage sector [35,36].…”

“…However, as mentioned above, the results of previous research concluded that window replacement is not necessarily a better energy saving measure. Considering the energy used in the life cycle of the windows, restoring, instead of replacing the windows, can be a better choice [34]; in addition, the energy cost related to the transport of the new elements is avoided. The interviewees also emphasised that restoration efforts compatible with the heritage building should be encouraged with the help of incentives so that people are willing to pay more for them.…”

Climate change mitigation targets have put pressure to reduce the carbon footprint of cultural heritage buildings. Commonly adopted measures to decrease the greenhouse gas (GHG) emissions of historical buildings are targeted at improving their energy efficiency through insulating the building envelope, and upgrading their heating, cooling and lighting systems. However, there are complex issues that arise when mitigating climate change in the cultural built heritage sector. For instance, preserving the authenticity of heritage buildings, maintaining their traditional passive behaviours, and choosing adaptive solutions compatible with the characteristics of heritage materials to avoid an acceleration of decay processes. It is thus important to understand what the enablers, or the barriers, are to reduce the carbon footprint of cultural heritage buildings to meet climate change mitigation targets. This paper investigates how climate change mitigation is considered in the management and preservation of the built heritage through semi-structured interviews with cultural heritage experts from the UK, Italy and Norway. Best-practice approaches for the refurbishment of historical buildings with the aim of decreasing their energy consumption are presented, as perceived by the interviewees, as well as the identification of the enablers and barriers in mitigating climate change in the cultural built heritage sector. The findings emphasise that adapting the cultural built heritage to reduce GHG emissions is challenging, but possible if strong and concerted action involving research and government can be undertaken to overcome the barriers identified in this paper.

“…Modern technological capabilities of manufacturers of translucent structures allow the mass production of window blocks with the thermal resistance of 1.0 m 2 0 С/W and higher, which exceeds the thermal resistance of external brick walls with a thickness of 770 mm (3 bricks). When they are used, the heat loss of buildings through the outer enclosure in the winter period of operation differs from traditional significantly [7][8][9][10][11][12][13][14][15]. In this case, from the point of view of providing thermal protection, the windows will not be the most vulnerable part of the outer shell of the building.…”

Abstract. The work presents the prerequisites to replace the window units in the historical buildings (primarily increased energy efficiency standards of buildings and significantly changed performance requirements of window units). The analysis of possible replacement options (full/partial) of window units of the historical buildings is done according to their architectural and historical values. A review is made of the existing technological capabilities of modern window systems and translucent filling (double-glazed windows), as well as the most common solutions used in practice. The issue of providing the temperature-humidity conditions of the nodes of adjunctions of the window blocks to the openings of the external walls in the winter operating conditions is considered. For this purpose, a numerical simulation of the temperature fields of the junction points is made for various structural embodiments of window frames. It is established that in the case of a full replacement of window blocks and maintaining the existing structure of external walls (the calculation is made using the example of the most common external wall for Central Russia -a brick wall 770 mm thick), condensation may form on the inner surface of window slopes. Different options are suggested for window blocks installation, which ensure the fulfillment of sanitary and hygienic requirements. Further directions for the research on the use of modern types of translucent structures in the historical buildings are outlined.
