The Impact

Globally, buildings account for nearly 40% of the total primary energy consumption and are responsible for 20% of the total greenhouse gas emissions. Energy consumption in buildings is increasing with the increasing world population and improving standards of living. Current global warming conditions will inevitably impact building energy consumption. To address this issue, this report conducted a comprehensive study of the impact of climate change on residential building energy consumption. Using the methodology of morphing, the weather files were constructed based on the typical meteorological year (TMY) data and predicted data generated from eight typical global climate models (GCMs) for three representative concentration pathways (RCP2.6, RCP4.5, and RCP8.5) from 2020 to 2100. It was found that the most severe situation would occur in scenario RCP8.5, where the increase in temperature will reach 4.5 °C in eastern Australia from 2080–2099, which is 1 °C higher than that in other climate zones. With the construction of predicted weather files in 83 climate zones all across Australia, ten climate zones (cities)—ranging from heating-dominated to cooling-dominated regions—were selected as representative climate zones to illustrate the impact of climate change on heating and cooling energy consumption. The quantitative change in the energy requirements for space heating and cooling, along with the star rating, was simulated for two representative detached houses using the AccuRate software. It could be concluded that the RCP scenarios significantly affect the energy loads, which is consistent with changes in the ambient temperature. The heating load decreases for all climate zones, while the cooling load increases. Most regions in Australia will increase their energy consumption due to rising temperatures; however, the energy requirements of Adelaide and Perth would not change significantly, where the space heating and cooling loads are balanced due to decreasing heating and increasing cooling costs in most scenarios. The energy load in bigger houses will change more than that in smaller houses. Furthermore, Brisbane is the most sensitive region in terms of relative space energy changes, and Townsville appears to be the most sensitive area in terms of star rating change in this study. The impact of climate change on space building energy consumption in different climate zones should be considered in future design strategies due to the decades-long lifespans of Australian residential houses.

The demand for energy in continues to grow. This projected growth in demand has spurned several initiatives aimed at forestalling potential shortages. The focus is on influencing the energy consumption patterns in industry especially during peak demand times when energy supply systems are strained. Moreover, the modern society has become more sensitive to the impact on the environment. More consumers are aware today of the need to conserve energy. A typical platform will enable industry to reduce electricity usage. The ability to manage energy usage more effectively saves businesses. To ensure the provision of adequate, secure and cost-effective energy supplies, resources using the latest cost options are being utilized. To promote the efficient utilization of energy and discourage wasteful and non-productive patterns of energy consumption, the energy policy's approach is to rely heavily on industry to exercise efficiency in energy conversion, utilization and consumption through the implementation of awareness programs. This research will encourage engineers in industry to evaluate, investigate, discover and discuss the various opportunities available to manage energy in industry utilizing a well-structured and engineered methodology and to consider energy management initiatives seriously.

The Impact

The growth of urban population as the result of economic and industrial development has changed our place of living from a prosperous place to where the resources are carelessly consumed. On the other hand, long-term climate change, i.e. global warming, has had adverse impact on our resources. Certain resources are on the verge of depletion as the consequence of climate change and inconsiderate consumption of resources, unless serious measures are implemented immediately. The building sector, whose share in the municipal energy consumption is considerably high, is a key player that may successfully solve the problem. This paper aims to study the effects of climate change on the energy consumption of buildings and analyze its magnitude to increase the awareness of how construction can reduce the overall global energy consumption. A descriptive-analytical method has been applied to analyze valid models of energy consumption according to different scenarios and to interpret the conditions underlying current and future energy consumption of buildings. The results clearly show that the energy consumption in the building sector increasingly depends on the cooling demand. With that being said, we can expect the reduction of overall energy consumption of buildings in regions with high heating demands, whereas rising the energy consumption in buildings is expected in regions with high cooling demand. To conclude, the long-term climate change (e.g. global warming) underlies the increased energy consumption for the cooling demand whose share in total energy consumption of buildings much outweighs the heating demand. Therefore, to conserve our resources, urban energy planning and management should focus on working up a proper framework of guidelines on how to mitigate the cooling loads in the energy consumption patterns of buildings.

The Impact

Building more energy efficient and sustainable urban areas that will both mitigate the effect of climate change and adapt for the future climate, requires the development new tools and methods that can help urban planners, architect and communities achieve this goal. In the current study, we designed a workflow that links different methodologies developed separately, to derive the energy consumption of a university school campus for the future. Three different scenarios for typical future years (2039, 2069, 2099) were run as well as a renovation scenario (Minergie-P). We analyse the impact of climate change on the heating and cooling demand of the buildings and determined the relevance of the accounting of the local climate in this particular context. The results from the simulations showed that in the future there will a constant decrease in the heating demand while for the cooling demand there will be a significant increase. It was further demonstrated that when the local climate was taken into account there was an even higher rise in the cooling demand but also that the proposed renovations were not sufficient to design resilient buildings. We then discuss the implication of this work on the simulation of building energy consumption at the neighbourhood scale and the impact of future local climate on energy system design. We finally give a few perspective regarding improved urban design and possible pathways for the future urban areas.

AbstractIn the Anthropocene era, climate change poses a great challenge in environmental management and decision-making for species and habitat conservation. To support decision-making, many studies exist regarding the expected vegetation changes and the impacts of climate change on European plants, yet none has investigated how climate change will affect the extinction risk of the entire endemic flora of an island biodiversity hotspot, with intense human disturbance. Our aim is to assess, in an integrated manner, the impact of climate change on the biodiversity and biogeographical patterns of Crete and to provide a case-study upon which a cost-effective and climate-smart conservation planning strategy might be set. We employed a variety of macroecological analyses and estimated the current and future biodiversity, conservation and extinction hotspots in Crete, as well as the factors that may have shaped these distribution patterns. We also evaluated the effectiveness of climate refugia and the NATURA 2000 network (PAs) on protecting the most vulnerable species and identified the taxa that should be of conservation priority based on the Evolutionary Distinct and Globally Endangered (EDGE) index, during any environmental management process. The highlands of Cretan mountain massifs have served as both diversity cradles and museums, due to their stable climate and high topographical heterogeneity. They are also identified as biodiversity hotspots, as well as areas of high conservation and evolutionary value, due their high EDGE scores. Due to the ‘escalator to extinction’ phenomenon and the subsequent biotic homogenization, these areas are projected to become diversity ‘death-zones’ in the near future and should thus be prioritized in terms of conservation efforts and by decision makers. In-situ conservation focusing at micro-reserves and ex-situ conservation practices should be considered as an insurance policy against such biodiversity losses, which constitute cost-effective conservation measures. Scientists and authorities should aim the conservation effort at areas with overlaps among PAs and climate refugia, characterized by high diversity and EDGE scores. These areas may constitute Anthropocene refugia. Thus, this climate-smart, cost-effective conservation-prioritization planning will allow the preservation of evolutionary heritage, trait diversity and future services for human well-being and acts as a pilot for similar regions worldwide.

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.
