This paper provides a critical review of the degradation, durability and service life prediction (SLP) of polymeric building envelope materials (BEMs), namely, claddings, air/vapour barriers, insulations, sealants, gaskets and fenestration. The rate of material deterioration and properties determine the usefulness of a product; therefore, knowledge of the significant degradation mechanisms in play for BEMs is key to the design of proper SLP methods. SLP seeks to estimate the life expectancy of a material/component exposed to in-service conditions. This topic is especially important with respect to the potential impacts of climate change. The surrounding environment of a building dictates the degradation mechanisms in play, and as climate change progresses, material aging conditions become more unpredictable. This can result in unexpected changes and/or damages to BEMs, and shorter than expected SL. The development of more comprehensive SLP methods is economically and environmentally sound, and it will provide more confidence, comfort and safety to all building users. The goal of this paper is to review the existing literature in order to identify the knowledge gaps and provide suggestions to address these gaps in light of the rapidly evolving climate.

The Cost

In Europe, the second recast of EPBD promotes long-term strategies to accelerate the path to nZEBs, fostering the cost-optimized building design already suggested in the EPBD first recast. Since the nZEB design is a complex optimization problem that is subjected to uncertainty in its boundary conditions (climate, technologies, market, ...), it is necessary to guarantee the resilience of the NZEB optimal design to possible variations of future scenarios, especially as regards the climate change. This work applies the new EdeSSOpt methodology (Energy Demand and Supply Simultaneous Optimization) developed by the Authors aiming at investigating the variation of the cost-optimized multi-family building design in different Italian future climate scenarios, therefore considering parameters related to the building envelope, energy systems and renewable energy sources. The method is implemented into the TRNSYS® (energy model), GenOpt (optimizer) and WeatherShift® (future climate scenario generator) tools. The resulting cost-optimal solutions in future scenarios are related to a lower global cost and a decreased total primary energy consumption. Beyond the future trends of such performance indexes, the fact that most of technical solutions associated with the optimal solutions have not changed with the studied climate scenarios, indicates a certain resilience of the optimal design variables facing climate change.

Abstract Climate change has become a real challenge in different fields, including the building sector. Understanding and assessing the impact of climate change on building energy performance is still necessary to elaborate new climate-adaptive design measures for future buildings. The building energy consumption for heating and cooling is mainly related to the building envelope thermal performance. In this study, the winter heat loss and summer heat gain indicators are proposed to assess and analyse the potential impact of climate change on opaque building envelope elements for different climate zones in Morocco over the next 40 years. For that purpose, a one-dimensional heat transfer model is used to simulate the heat transfer through the multi-layer structure of the wall/roof. A medium climate change scenario is considered in this study. The results showed that the current average walls and roof summer heat gain is expected to increase of about 19.2–54.3% by the 2060s depending on the climate zone, versus a less important decrease in winter heat loss varies between –10.6 and –20.6%. This paper provides a reliable evaluation of the climate change impact on building envelope thermal performance, which leads to better adjustments in future building envelope designs.

Silicone Membranes

Three room-temperature fluid-applied silicone membranes intended for application in the building envelope were studied in this work. The membranes were subjected to 5000 hours of accelerated UV and moisture aging to evaluate their resistance to long-term aging. The properties of the membranes were studied to understand any degradation mechanisms that might happen during accelerated aging. The weight loss, wetting propensity, cracking and oxidation resistance, and storage modulus were measured at different intervals during the 5000 hours of aging. Based on the material characterization results, the silicone membranes proved to be resilient under aggressive accelerated UV radiation and moisture aging, conditions which can be expected as a result of climate change.

The condition of climate change is attributed directly or indirectly to activities related to the human being, as a more transcendental effect the increase of temperature is highlighted. Such a condition is not taken into account in the development of current constructions, so it is sought to propose the use of thermal insulating materials that will give a thermal comfort to the user and a reduction of energy use, which in turn will be an environmental advantage. There are various types of thermal insulating materials, however, it is proposed to be sustainable, as it is intended not to contribute to climate change and to meet the appropriate specifications of the building envelope, in order to ensure the users comfort of current and future dwellings, different factors, such as orientation, as well as specific parameters, will be taken into account as part of the development of the aforementioned ones. The construction development of the current house-room does not take into account the continuous thermal alterations that occur by the continuous climate change, ignoring the basic needs of the thermal comfort of the user; so sustainable materials are recommended, which meet thermoinsulating properties without causing an environmental impact.

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.

This paper addresses the effects of long-term climate change on retrofit actions on a school building located in a Mediterranean climate. Dynamic energy simulations were performed using Termolog EpiX 11, first with conventional climate data and then with future year climate data exported from the CCWorldWeatherGen computational software. To date, many incentive actions are promoted for school renovations, but are these measures effective in preventing the discomfort that will be found due to overheating generated by climate change? Today, one of the main objectives in retrofit measures is the achievement of ZEB (Zero Energy Building) performance. Achieving this target requires first and foremost a high-performance envelope. This study evaluates the impact of retrofit strategies mostly applied to the school building envelope, over the years, considering three different time horizons, until 2080. Thermal performance indices and indoor operative temperature under free-floating were evaluated. The results highlight that, with a changing climate, it is no longer possible to assume a constant static condition to evaluate retrofit actions, but it is necessary to develop a predictive mathematical model that considers the design variability for future years. There is an urgent necessity to ensure both the safety and comfort of buildings while also anticipating future variations in climate.

Abstract: The Mediterranean architectural style began to be a reference style in designing buildings in Indonesia since the 1990s and applied to various buildings including residential buildings because it offers an impressive aesthetic element of grandeur and its response to heat according to the origin region. The potential application of Mediterranean architectural style elements in the middle of Modern architectural style invasion can still be taken to resolve thermal problems caused by environmental issues namely climate change and global warming. This research aims to evaluate the thermal performance of Mediterranean-style residential buildings in response to the local climate and the potential adaptation of the envelope elements to Modern architectural styles using ECOTECT  simulations. The results showed that a sample house with a combination of three architectural styles shows that the Mediterranean architectural style can still be used and able to compete with other architectural styles at this time by including its Mediterranean style which presents grandeur, and incorporates elements of minimalist architectural style to give a modern nuance, also implementing shading strategies from Tropical architectural styles as adaptations to the tropical climate. That house sample has the longest thermal comfort duration compared to the others, which is 8.5 hours.Keywords: thermal building performance; building envelope; architecture style; environmental issue. Abstrak: Gaya arsitektur Mediterania mulai menjadi referensi gaya dalam mendesain bangunan di Indonesia sejak tahun 1990an dan banyak sekali diminati serta diaplikasikan ke berbagai bangunan tidak terkecuali bangunan rumah tinggal karena menawarkan unsur estetika yang mengesankan kemegahan dan responnya terhadap iklim sekitar yang cenderung panas sesuai dengan wilayah asalnya. Potensi pengaplikasian unsur-unsur gaya arsitektur Mediterania di tengah gempuran gaya arsitektur Modern masih dapat diperhitungkan dengan tujuan untuk menyelesaikan permasalahan termal berupa peningkatan temperatur yang diakibatkan oleh isu lingkungan yaitu climate change dan global warming. Penelitian ini bertujuan untuk mengevaluasi kinerja termal bangunan rumah tinggal bergaya Mediterania dalam responnya terhadap iklim setempat dan potensi pengadaptasian elemen selubungnya terhadap gaya arsitektur Modern dengan menggunakan simulasi termal ECOTECT. Hasil penelitian menunjukkan bahwa sampel rumah dengan perpaduan tiga gaya arsitektur menunjukkan bahwa gaya arsitektur Mediterania masih bisa dipergunakan dan mampu bersaing dengan gaya arsitektur lainnya saat ini yaitu dengan memasukkan gaya Mediterania sendiri yang mempresentasikan kemegahan, dan juga memasukkan unsur gaya arsitektur Minimalis untuk memberi balutan nuansa modern, serta menerapkan strategi shading dari gaya arsitektur Tropis sebagai adaptasi dengan iklim tropis. Sampel rumah tersebut memiliki durasi kenyamanan termal paling lama dibanding yang lainnya yaitu selama 8,5 jam.Kata Kunci: kinerja termal bangunan; selubung bangunan; gaya arsitektur; isu lingkungan
