“…Users' behaviour has an important role to play in mitigating climate change, as it determines the preference and choice for room temperature and ventilation, for instance [38], and can help target specific groups in carbon reduction strategies. Many studies highlighted the high energy saving potential derived from changes in user behaviour [39][40][41][42][43], which they estimated to range from 62 to 86% [40]. Human behaviour, however, can lead to a rebound effect in energy usage.…”

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.

In this study, the analysis of thermal comfort and energy utilized by occupants in a personal conditioned space at Lagos State, Nigeria is examined. Since thermal comfort expresses the satisfaction of an occupant in a space, therefore it enhances or inhibits the productivity of occupants in an environment. The heat transfer through the conditioned space with optimal insulation using brick walls and insulation typical of a Nigerian building is formulated using the heat conduction and Navier-Stokes equation. While the comfortability of occupants in the space is determined using the predicted mean vote (PMV) and predicted percentage dissatisfied (PPD) indices. It is observed that occupants in the conditioned space are thermally comfortable when the ventilation rate is set to 8 l s −1 with non-insulated walls. With insulated wall, thermal comfortability of the space is set to 2 l s −1 adopting insulated wall thickness of 0.045 m. Energy cost using on grid power for non-insulated wall cost N4, 016.996 and N1, 015.512 for insulated walls annually. Utilizing off grid power source (diesel powered generator set) annual energy cost is determined as N2, 137.97 using thermal insulation and N8, 527.85 without insulation. It is observed that personalized cooling helps to achieve increased comfort of occupants in a conditioned space, also maximizing energy utilized. Consequently reducing energy wastage.

“…The most optimal restoration option for potential investors is the historical buildings adaptation to modern use (see fig. 1) [1]. This process implies the preservation / reconstruction of the most valuable from the historical point of view building elements (for example, elements of the facade or the interior of the building), and also the provision of modern requirements for comfort, safety, operation and maintenance simplicity.…”

Abstract. The work presents the possibilities of using PVC window units in the historical buildings. There are reasons of their widespread use in projects of adaptation of historical buildings for modern use. The analysis of possible replacement options of window units of the historical heritage is done according to their architectural and historical values of the exterior and the interior. A review is made of the existing technological capabilities of modern PVC window systems used in the historical buildings. Examples of application of PVC window units in historical buildings of various architectural styles are given. Examples of structural solutions of window units and stained glass windows made of PVC in historical heritage are considered. The analysis of perspective ways of the use of modern types of translucent fillings in historical buildings can significantly improve the energy performance of these buildings and provide them with conditions that meet the modern requirements of comfort and safety.
