“…Still, the existing research has seldom included educating and motivating occupants for energy-efficient behaviour as a retrofit Reviewing the contribution of retrofitting measure, mainly because of its complexity of measuring, analysing and implementing. Nevertheless, Pajek et al (2022) have assessed educating occupants on effectively using natural ventilation and external shading as a retrofit measure. Many researchers cite deep energy retrofitting as the most intensive category, but only 13% of the 80 papers have investigated this topic.…”

“…Energy retrofitting is not merely increasing the insulation level. Still, it considers energy requirements for summer space cooling as well (Pajek et al , 2022), so energy retrofitting is focused on upgrading building components and services to achieve climate-resilience. Changing occupant behaviour should also be considered as a retrofit strategy [refer to (retrofitting ∪ energy retrofitting) set in Figure 5].…”

“…Roof and wall painting were assessed based on the colour and specification. Façade painting with light colours contributes to a cooling demand reduction of 3%–5% under both representative concentration pathways (RCP), including RCP4.5 and RCP8.5, but overall annual energy demand reduction is 0%–1% in temperate regions (Pajek et al , 2022). Overall, the contribution of painting with light colours for climate-resilience is not efficient for temperate and cold regions because of increasing heating demand but is appropriate for tropical and arid regions.…”

“…On par with the Chinese standard, the uncomfortable duration imposed by following the same ventilation schedule year-round for a single-family house (SFH) in a cold region is around one month, which lies in the winter season (Li et al , 2022a). Under both RCP4.5 and RCP8.5 scenarios and from 1982 to 2099, natural ventilation can diminish the cooling demand in temperate regions (Pajek et al , 2022), where night-time ventilation is more effective than daytime (Anwar et al , 2021). Natural ventilation contributes to enhancing all three dimensions of climate-resilience in all four climate zones.…”

Purpose Over the years, the significance of retrofitting has gained much attention with the unveiling of its different applications, such as energy retrofit and deep retrofit, to enhance the climate-resilience of buildings. However, no single study comprehensively assesses the climate-resilience of retrofitting. The purpose of this study is to address this gap via a systematic literature review. Design/methodology/approach Quality journal studies were selected using the PRISMA method and analysed manually and using scientometrics. Three dimensions of climate-resilience, such as robustness, withstanding and recovery, were used to evaluate the contribution of retrofit measures for achieving climate-resilient houses across four climate zones: tropical, arid, temperate and cold. Findings Most passive measures can enhance the robustness of residential buildings but cannot verify for withstanding against immediate shocks and timely recovery. However, some passive measures, such as night-time ventilation, show excellent performance over all four climate zones. Active measures such as heating, ventilation and air conditioning and mechanical ventilation with heat recovery, can ensure climate-resilience in all three dimensions in the short-term but contribute to greenhouse gas emissions, further exacerbating the long-term climate. Integrating renewable energy sources can defeat this issue. Thus, all three retrofit strategies should appropriately be adopted together to achieve climate-resilient houses. Research limitations/implications Since the research is limited to secondary data, retrofit measures recommended in this research should be further investigated before application. Originality/value This review contributes to the knowledge domain of retrofitting by assessing the contribution of different retrofit measures to climate-resilience.

The study aimed to assess the overheating vulnerability of an existing multi-apartment building built in 1971 in Podgorica, Montenegro. The building consists of 80 apartments and is mostly still in its original state. Firstly, the building was modelled in EneryPlus, and a parametric study was performed with jEPlus. The energy need for heating and cooling was simulated using parameters such as thermal insulation level, window properties, external surface solar absorptivity, shading activation set-point, and natural ventilation cooling intensity. Moreover, the energy need was determined for four different climate periods, namely for the current and three future periods up to the end of the 21st century under the RCP8.5 climate change scenario. The total number of building models equalled 648 for each of the four climate scenarios, resulting in 2,592 simulated cases. After that, the overheating vulnerability score was determined using the minimax regret method and cooling energy need as a performance indicator. The best retrofit action was determined by identifying the most favourable combination of the overheating vulnerability and total energy need. The results deliver the appropriate energy retrofit actions to limit the increase in overheating risk and provide for climate change adaptation of the multi-apartment building stock in Montenegro.
