“…It also shows that heating loads are going to be completely removed in June, July, and August months, and cooling loads are required to keep the interior of the building within comfort zone. This result is also comparable to [9] and [13], confirming the reduction of heating loads in future times and that the heating loads remain prominent energy loads until 2080. As Figure 8 shows, there is no requirement for active cooling devices in the present time for this case study, which shows the applied design solutions were successful in avoiding overheating risk inside the building.…”

Abstract:The likely increasing temperature predicted by UK Climate Impacts Program (UKCIP) underlines the risk of overheating and potential increase in cooling loads in most of UK dwellings. This could also increase the possibility of failure in building performance evaluation methods and add even more uncertainty to the decision-making process in a low-carbon building design process. This paper uses a 55-unit residential unit project in Cardiff, UK as a case study to evaluate the potential of thermal simulations to identify risk in the early design stage. Overheating, increase in energy loads, carbon emissions, and thermal bridges are considered as potential risks in this study. DesignBuilder (DesignBuilder Software Ltd., Stroud, UK) was the dynamic thermal simulation software used in this research. Simulations compare results in the present, 2050, and 2080 time slices and quantifies the overall cooling and heating loads required to keep the operative temperature within the comfort zone. Overall carbon emissions are also calculated and a considerable reduction in the future is predicted. Further analysis was taken by THERM (Lawrence Berkeley National Laboratory, Berkeley, CA, USA) and Psi THERM (Passivate, London, UK) to evaluate the thermal bridge risk in most common junctions of the case study and the results reveal the potential of thermal assessment methods to improve design details before the start of construction stage.

“…Orme et al [8] presented a study which also clarified that in a lightweight, well-insulated house an outdoor air temperature of 29 • C may cause overheating to more than 39 • C inside the building. However, Andric et al [9] evaluated the long-term impact of climate change on the heating demand in the future using a six-storey…”

“…The correlation between the buildings energy demand and the climate change effects emerged as a crucial research topic in the early 1990s, taking also a run-up over the past two decades; in [7] the impact of climate change in different climate zones was assessed; the authors in [8] explored how the different energy retrofitting interventions have to be effectively identified according to the future climate conditions in Sweden. A statistical survey was used to select the most representative buildings typology to take into account as a reference sample for the investigation purpose.…”

Climate change affects the buildings’ performance, significantly influencing energy consumption, as well as the indoor thermal comfort. As a consequence, the growing outdoor environmental temperatures entail a slight reduction in heating consumption and an increase in cooling consumption, with different overall effects depending on the latitudes. This document focuses attention on the Italian residential sector, considering the current and reduced meteorological data, in anticipation of future climate scenarios. According to a sample of 419 buildings, referring to the climatic conditions of Milan, Florence, Rome, and Naples, the heating and cooling needs are calculated by a simplified dynamic model, in current and future conditions. The effects of the simplest climate adaptation measure, represented by the introduction of new air conditioners, have been also evaluated. The simulations results show an important reduction in complex energy consumption (Milan −6%, Florence −22%, Rome −25%, Naples −30%), due to the greater incidence of heating demand in the Italian context. However, the increase in air conditioning electrical consumption over the hot season (Milan +11%, Florence +20%, Rome +19%, Naples +16%) can play a critical role for the electrical system; for that reason, the introduction of photovoltaic arrays as a compensatory measure have been analysed.

“…In recent years, the design or restructuring of buildings has been to adapt to different climate changes and to minimise building energy consumption. Due to the rapidly increasing average global temperature, indicative of anthropogenic global warming [17][18][19][20][21], necessary retrofit measures are required for existing buildings to accommodate the high ambient temperature [22][23][24]. However, the pre-selection of suitable retrofit measures is dependent on the regional climate changes [25][26][27].…”

Building Energy Retrofit Measures in Hot-Summer–Cold-Winter Climates: A Case Study in Shanghai

et al. 2019

Building retrofit measures provide a significant means of mitigating the effect of climate change on buildings by enhancing building energy performance at a beneficial cost-effectiveness. An insight into the applicable building retrofit measures within a climate zone will guide the optimisation framework to attaining sustainability in architecture and the built environment. This article presents a brief overview of recent studies on retrofit measures and its application on a variety of buildings in hot-summer–cold-winter climates, with emphasis on Shanghai. Findings show that the major retrofit measures include improvement in the building envelope, heating, ventilation and cooling (HVAC) and lighting, supported by photovoltaic (PV) systems, accordingly. Furthermore, the study identifies key elements and plausible challenges for the evaluation of building retrofit measures in this region. In this regard, financial barriers and lack of standards and regulatory support are the main challenges identified. These insights provide a systematic approach to guide building researchers, practitioners and decision-makers in the design and development of existing and new retrofit measures for the future of rapidly growing cities with a broad climate variation scope.
