Life Cycle Analysis (LCA) is the most appropriate method to quantify scientifically the environmental and health impacts of buildings. The purpose of this research is to determine, at the neighborhood scale, the most important sources of buildings’ environmental impacts, based on twelve different environmental impacts including the health impact. This paper compares the impacts on the environment generated by an existing energy efficient neighbourhood, where all the buildings should be passive, and its transformation into a zero-energy district thanks to the addition of numerous photovoltaic panels on the roofs of the buildings. For that, we used the combination of three simulation tools — ALCYONE, COMFIE-PLEIADES and nova-EQUER for studying the Life Cycle Assessment (LCA) of buildings and networks (roads, parking, etc). An eco-neighbourhood, located near the University of Liege in Belgium, has been selected as the case study. The buildings heating modelled by the dynamic thermal simulation has an average heating load of 15.4 kWh/m².year.Photovoltaic panels on all the roofs of the buildings allow achieving a nearly zero-energy neighbourhood and can mitigate up to 25% of greenhouse gas emissions of the passive neighborhood and reduce 5% of its health impacts. However, the photovoltaic panels have a mixed environmental record for other indicators, with a majority of the environmental impacts being improved compared to the passive neighborhood, but four of the twelve environmental impacts studied being increased.We also notice the strong predominance of the occupation phase on the life-cycle environmental impacts of this nearly zero-energy neighborhood. The use phase concentrates more than 70% of the greenhouse gas production and of the cumulative total energy demand of the neighborhood calculated during 80 years. Moreover, the results show a very strong participation of the mobility component and the household waste management component, in the LCA, at the neighbourhood level. The cumulative energy demand from inhabitants’ mobility and waste management during the use phase was 60% of the total cumulative energy demand of the neighbourhood, over its entire life cycle. The results show also that an improved mobility management allows reducing all the environmental impacts of the neighborhood and may reduce its health impacts up to 32%. [less ▲]

Nowadays, with the new technology, the explosion of new products and the implementation of the new construction rules, it is important to evaluate the effect of the strong human pressure on nature. Thus, the analysis of the life cycle of a product (i.e., building) makes it possible to evaluate its main environmental impacts (energy demand, greenhouse gas emissions, product waste, water consumption, etc.) from raw materials manufacturing to its end of life (demolition).The purpose of this research is to carryout a meticulous statistical analysis aimed to better understand and to discern better the impact of sustainable buildings and old buildings on the environment. In addition, this research identifies the main elements that affect the environment during the construction, operation, renovation, and demolition of buildings.59 residences were analyzed (29 durable residences and 30 old residences), distributed in two districts of the Liege city. Several software tools were used(IBM SPSS statistical, ALCYONE, COMFIE-PLEIADES, and nova-EQUER) to statistically evaluate the 12 environmental impacts considered in this study .The results showed that the impacts of sustainable buildings and old buildings on the environment are very significant. Despite that, it is difficult to identify a clear difference between the environmentalimpact from old and sustainable buildings .The total lifecycle greenhouse gas(LCGHG) and energy of the whole the residential buildings represents 17.225 ktCO2-e and 362.8TJ, respectively, over 100 years. The building operation phase (or use phase) consume significant amount of life cycle energy (from 81.0 to 94.3%), but also, the largest contribution to the life cycle greenhouse gas (between 75.6% and 91.3%).

The protection of the environment is one of the main objectives in the European Union. The aim is to protect Nature,that is constantly revolting against the strong mechanization and the new technologies. An environmental cost is the environmental impact of a product, based on its damage and prevention charges. The main purposes of this research are to quantify the different environmental damages generated by a sustainable neighborhood and also, to evaluate those ones in a life cycle of 80 years, as well as the damages derived from influence of water management and urban density on the environment. Twelve environmental impacts were evaluated by the Pleiades and Nova-EQUER simulation software, under four phases (construction, use, renovation and demolition), before being translated into costs to the ecosystem. The results show that the highest harm of a sustainable neighborhood in Belgium, are due to the eutrophication (55.4%), and the greenhouse gas (31.2%) impacts, apart from the natural components, which, their greatest harms on the overall environmental cost balance are: the water (35.3%), the waste (21.9%), and the transport (18.1%). A neighborhood with a good rainwater recovery system allows to save the 76% of the costs related to the water [less ▲]

During this decade, the human exploitation on the environment is being to completely change the nature of the ecosystem. According to the experts, Life Cycle Analysis (LCA) is the most appropriate method to quantify the different environmental impacts of human activities.The main purpose of this research is to quantify, at the neighborhood scale, twelve environmental impacts. Moreover, this research proposes to study two sustainable strategies to reduce these impacts on the environment: a sustainable urban mobility and the addition of photovoltaic panels on the buildings’ roofs. We will thus seek to quantify the impact of mobility management and local energy production on the environmental balance sheet of a sustainable neighborhood.For that, we used the combination of three simulation tools — ALCYONE, COMFIE-PLEIADES and novaEQUER for studying the Life Cycle Assessment (LCA) of a case study. An eco-neighborhood, located in Belgium, has been selected as the modeling site. The results show that a sustainable mobility management in cities allows reducing from 4% to 50% of each of the twelve environmental impacts calculated for a neighborhood over its entire life cycle. The photovoltaic panels can mitigate up to 25% of greenhouse gas emissions, but this scenario generates an increase up to 18% for the damage to biodiversity and 21% for waste production. [less ▲]

The current worldwide climate change situation motivates researchers to look for solutions to reduce its impacts on the environment. One of the solutions is the increase of energy performance and efficiency especially in buildings in respect to environmental norms. In this aspect, the Wal-e-cities projects funded by ERDF (European Regional Development Fund) aim to create smart tools in terms of connectivity, governance, living environment, mobility, energy and environmental impacts, for the Walloon Region in Belgium (Europe). The smart energy management in Wallonia will contribute to reducing problems related to the increase of pollutions due to buildings energy consumption. This paper is a part of the Wal-e-cities_energy project and focuses on the heat consumption and demand assessment of residential and tertiary buildings in Wallonia. The heat consumption data coming from the regional energy reports were used to estimate the heat consumption and heat demand of each residential and tertiary building type. Thereafter, these estimates combined with cadastral data and territorial data were spatialized on the urban region of Liège. The heat demand and consumption assessment is modelled at the building scale for the urban region of Liège, but it is represented on geographical maps on a statistical sector scale. For residential buildings, the heat consumption and demand are mainly related to the number of buildings in the statistical sectors, whereas for tertiary buildings the type of building also has a paramount influence. In addition, the difference between the heat demand and the heat consumption of the different types of buildings varies in a narrow range, between 15 and 18% for residential buildings and 16 to 18% for tertiary buildings.

In the context of sustainable development, the environmental aspects of urban areas are taken into account by correlating them with their energy consumption. The purpose of this research is to collect and analyze the energy consumption data due to the transport in Belgium, and more precisely in the Liege province. But, also to make forecasts of these same consumptions to the horizon 2030-2050. The methodology chosen allow to model and improve the energy consumption for city-wide transports and to forecast the evolution of city energy consumption to simulate the effects of certain urban development strategies. We focus here on the city of Liege which we will compare the different data of energy consumption with those of other cities. The analysis of the impacts of mobility on energy consumption and greenhouse gas was based on seven scenarios established through several surveys and researches. The results showed that the daily mobility of inhabitants has a significant effect on CO2 emission and energy consumption. It is necessary to act in the long term by encouraging public transport such as vehicles with low energy consumption. The energy consumption in transportation sector can decrease up-to 19%, by reducing between 10% and 20%, of displacement by private car, and an increase up to 60%, both combined displacement by bike (for the distances small than 12 km), and walking (distances small than 1km).

This research was conducted in order to assess the impact that climate change has on the demands for heating and cooling energy in hospitals in six cities located in six countries in the Indian Ocean region. Three scenarios (B1, A1B, and A2) of the Intergovernmental Panel on Climate Change (IPCC) were applied in the undertaking of this work. The hourly outdoor data relating to air temperature, wind speed, relative humidity, radiation, and atmospheric pressure recorded over the last 30 years were used as inputs by Meteonorm software to enable the forecasting. The averages obtained in all the 18 models used in the IPCC report 2007 were included in the Meteonorm software and applied for assessing the future climate. The Energy-Plus software was used for assessing the thermal performance of hospitals under natural ventilation, then the energy demand during five periods (past, current, 2030, 2060, and 2090). Thermal insulation was utilized as a passive strategy for reducing cooling and heating energy consumption in the hospitals. Results showed that the use of an envelope of thermal insulation in hospitals was one of the solutions that allowed a reduction in the energy consumption for cooling and heating while increasing the thermal comfort within the hospital. Moreover, by 2090, the ventilation system wasrecommendedinallthesehospitals forimprovingthequalityofindoorair,sincetheheatratewasveryhigh. In the cases of the six islands in the Indian Ocean, each of them represented by one city, the annual energy demand for cooling will increase between 17.1 and 25.4% by 2030; 34.6 and 50.2% by 2060; and 60.8 and 95.1% by 2090. With the use of passive design as a strategy, the annual mean thermal performance of hospitals is predicted to increase to 184% by 2060, while 40% of the cost of cooling energy will be saved. Despite this, the outdoor climate will be 5% harsher in Victoria than in other cities by the year 2090. [less ▲]

Nowadays, major European cities witness one of their greatest challenges in history. Increasing migration from the rural areas, not to mention the massive migrations from the east, contributes in aggravating the challenge. As a response, United Nations urban agendas promote for developing urban spatial frameworks based on appropriate compactness, polycentrism and mixed use, preventing urban sprawl and marginalization. In this research, a methodology is presented that aids the decision making on roof stacking as a sustainable approach towards urban densification. Brussels Capital Region in Belgium is chosen as a case study to represent the outcomes of a methodology that has been developed to identify urban densification potential through roof stacking. Further applications to generalize the approach to fit other cities in Europe would help create additional opportunities to develop an automated tool for estimating such potentials on a wider scope.

Facing the need to accommodate a growing number of inhabitants in major European cities, this research aimed to establish a methodology that facilitates decision making on urban densification through roof stacking. The methodology adopts a systematic approach on three consecutive levels: urban, engineering, and social. Multiple criteria are identified to assess and map the roof stacking potential in terms of location and number of added floors. The Brussels Capital Region was chosen as a case study to experiment with the developed workflow chart and validate the proposed approach, using ArcGIS software, by creating a map of the urban densification potential through roof stacking of Brussels at the city scale. The results show a realistic potential of accommodating 30% of the expected population increase in Brussels by the year 2040 using only roof stacking, provided that the current urban regulations are respected. In addition, a theoretical potential to accommodate more than the expected population increase by the same year is proposed provided that urban planning regulations are relaxed in relation to the height of buildings. Further applications to other cities in Europe would help create additional opportunities to develop an automated tool for estimating such potentials on a wider scope. [less ▲]

Creating urban public spaces ensuring the comfort of city dwellers is one of the fundamental issues of sustainable development of cities. The climate has always been considered as one of the major elements of the dynamics and atmosphere of a city. Vegetation implanted in an urban environment modifies the physical environment (light, heat, wind, sound, humidity, etc.). The aim is to highlight the impact of the presence of vegetation on the use of outdoor public spaces in summer and on the users behaviors, as well as on the variation of the urban microclimatic parameters. The case of the city of Constantine (Algeria) with a semi-arid climate is used as case study. The research method uses surveys, observations, in situ measurements and numerical simulations. The presence of vegetation has a positive effect for the qualification of the thermal and visual environments for this type of climate. [less ▲]

Fundamentals of vernacular architecture have been used in bioclimatic architecture which has gradually become the inspiration of various movements in contemporary architecture. The study points out that the development of bioclimatism in architecture has followed the pattern of a natural evolutionary process in which “natural selection” is likely motivated by several factors, including resources and environment problems, and driven by different mechanisms including novel building design concepts and methods, new standards and codes, discoveries in building science and construction costs. This study is an effort aimed to clarify the evolution process of the bioclimatic approach in architecture over time and its influences on contemporary movements in architecture. The paper shows also that the evolutionary theory generated new scientific tools able to improve building design thanks to simulation-based optimization methods applied to building performances. Finally, this study investigates new motivations in the era of climate change whose effects are expected to introduce more challenges as well as more trends towards a sustainable built environment through the new concept of Eco-adaptive architecture.

This paper presents the SOLEN integrated online tool, dedicated to citizens and local authorities. This methodology, developed to allow precise energy assessment (heating, cooling, ventilation, lighting, appliances, and cooking but also local production of renewable energy) of household energy uses, is firstly introduced. SOLEN uses a typological classification of buildings and thermal simulations. Many parameters are defined and taken into account to capture the specificities of numerous types of buildings exhaustively (e.g. type of buildings; number of floors; common ownership; orientation; thermal performances of the walls, floors, roofs, and windows; and ventilation type). These results related to building energy consumption are then crossed, in an integrated approach, with several indicators of urban sustainability, to take into account in the balance of the impact of the location of buildings on transportation energy consumption or the impact of the urban form on the production of solar renewable energy. This tool makes accessible to a large non-specialized audience the results of a three-year scientific research study in Wallonia (Belgium) and was awarded an Energy Globe Award (Belgium) in 2014. The first feedback from users is presented to conclude this contribution. [less ▲]

The adaptive approach was used for this purpose. A specific questionnaire based on the ISO7730 and 10551 was designed to collect these data. A total of 400 people participated in this study, and the survey was conducted during rainy and dry seasons. This study discusses the influence of gender, clothing, activities, voters’ mind state and occupants’ control strategies on adaptive comfort assessment. In addition, various comfort parameters were calculated for these buildings. Results show that, in both studied places, the lower and upper acceptable temperatures for 80% of the voters were 23.2 °C and 26.8 °C, while 90% of the customers and patients reported a comfortable temperature range of 24.5–26.2°C. This will help to define proper guidelines to build more comfortable buildings in Madagascar and other countries of the Indian Ocean. [less ▲]

The increase outdoor temperature acts directly on the indoor climate of buildings. In Cameroon, the energy consumption demand in the buildings sector has been rapidly increasing in recent years; so well that energy supply does not always satisfy demand. Thermal insulation technology can be one of the leading methods for reducing energy consumption in these new buildings. However, choosing the thickness of the insulation material often causes high insulation costs. In the present study, the optimum insulation thickness, energy saving and payback period were calculated for buildings in Yaounde´ and Garoua cities, located in two climatic regions in Cameroon. The economic model including the cost of insulation material and the present value of energy consumption and the cost over a life time of 22 years of the building, were used to find the optimum insulation thickness, energy saving, and payback period. Materials that extruded polystyrene were chosen and used for two typical wall structures (concrete block (HCB) and compressed stabilized earth block wall (CSEB)). The early cooling transmission loads, according to wall orientations and percentage of radiation blocked were calculated using the explicit finite-difference method under steady periodic conditions. As a result, it was found that the west- and east-facing walls are the least favourite in the cooling season, whereas the south and north orientations are the most economical. Although wall orientation had a significant effect on the optimum insulation thickness, it had a more significant effect on energy savings. In equatorial region (Yaounde´), for south orientation, the optimum insulation thickness was 0.08 m for an energy savings of 51.69 $/m2. Meanwhile, in tropical region (Garoua), for north orientation, the optimum insulation thickness was 0.11 m for an energy savings of 97.82 $/m2. [less ▲]

Fuel poverty refers to a situation in which an individual or household is not able to meet their basic energy needs. Fuel poverty is currently growing in the European Union. Research in this field is often limited to the assessment of the current risk of fuel poverty based on energy consumptions due to housing. Urban sprawl generates a significant increase in energy consumption related to daily mobility, which generates energy poverty related to transportation needs. This article presents a methodology for modeling the current and future energy poverty of households in Europe on the basis of energy consumptions due to housing, to daily mobility and their combination. Indicators for fuel poverty and transport poverty will be based on Hills’ method, which is widely recognized internationally for fuel poverty assessment and which takes into account two thresholds: energy expenses of households and their available residual income. This article will outline the spatial modeling process of energy costs due to dwellings and mobility thanks to the coupling of a GIS tool, cadastral datasets, existing methods for the assessment of buildings and transport energy consumptions and updated databases (EPB certificates, detailed mobility surveys, data from smart meters, mobile phones and GPS). Different scenarios will be selected to predict the evolution of fuel and transport poverty until 2040 on the basis of national and European prospective studies or, alternatively, based on the historical evaluation of some key parameters and their extrapolation. The evolution of built-up areas will be model thanks to the multinomial logistic regression model (MLR) that enables to visualize the consequence of different urban densities expansion. The different parameters that will influence the evolution of fuel and transport poverty until 2040 will be highlighted (climate change, urban expansion, fuel prices, energy performance of buildings and vehicles, etc.).

The well-known Darwinian evolutionary theory (1859) introduced natural selection as the most important mechanism of evolutionary processes at every level from biological systems, including species, individual organisms… to molecules such as DNA or proteins. In architecture we observe similar evolution processes which lead to the development of various architectural movements and concepts from common primitive living structures. The study points out that the development of bioclimatism in architecture has followed the pattern of a natural evolutionary process in which “natural selection” is likely motivated by several factors, including resources and environment problems, and driven by different mechanisms including novel building design concepts and methods, new standards and codes, discoveries in building science and construction costs.
