“…As an example, results of a study in central part of London focus on the envelope, structure and operational systems (Azzouz et al, 2017). Another LCA study in Tianjin represents that operational stage not only consumes more energy but also contribute more CO 2 emissions (Ma et al, 2017).…”

Energy consumption by occupants during utilization phase concerns the increase of global warming potential and a shortage of energy resources. Energy consumption in an effective way decreases the risk of global warming. Use of materials with high embodied energy and embodied carbon in building components may improve the energy performance of the building, but it can ameliorate global warming. The issue of Life Cycle is quite new in the Middle East, so is it effective or does it work in developing countries. One of the goals of this study is to use three different wall types in a two-story office with close embodied energy and U-value (overall heat transfer coefficient) and compare the performance of each wall in the building from the Life Cycle point of view. Subsequently, analyzing the importance of other factors such as embodied carbon and transportation in choosing appropriate material in the construction sector. According to this study, even in countries like Iran (''which holds the world's fourth-largest proved crude oil reserves and the world's second-largest natural gas reserves'') with very low amount of database about the embodied energy, the right material should be chosen to reduce the fuel consumption and CO 2 emission.

“…In addition, a careful selection of low-EI materials can reduce CO 2 emission by up to 30% in the construction phase [14]. Previous research into low-EI buildings strongly emphasizes the value of the early planning and design phases during the building production processes, such as the orientation of buildings, bioclimate characteristics, and material selection [3,8,33,34].…”

“…Thus, making the right decision on construction methods, materials and installations is critical to reducing environmental impact [6,8]. Material selection as well as the bioclimatic characteristics of a building must be well evaluated or analyzed at the early design phase [3,8]. Consequently, it is vital to reduce the energy use and environmental impact attributed to the housing sector, especially in the early planning and design phases, which preordain the environmental impact levels of housing.…”

“…The consequent impact on the environment cannot be ignored. To implement sustainable development in the built environment, reducing energy consumption, lowering CO 2 emissions, and adopting low-environmental-impact (low-EI) materials are essential for the corresponding measures [3]. Buildings constructed with high energy materials have higher energy demand in the building production stage.…”

Demand-Oriented Design Strategies for Low Environmental Impact Housing in the Tropics

This study aims to propose design strategies for low environmental impact (low-EI) housing in the tropics while incorporating user needs to increase its acceptance in the market. The Fuzzy Delphi method (FDM) is adopted initially to draw the user needs for contemporary housing, after which the crucial design factors are identified. The analytic network process (ANP) and house of quality (HOQ) are further utilized to incorporate weightings of user needs into crucial design factors to establish appropriate design strategies. The results show "utility" (0.177), "durability" (0.169), and "comfort" (0.168) are the three greatest user needs for housing. After incorporating the weightings of user needs into design factors, building layout (0.334) and materials (0.302) turned out to be the most important considerations during the planning phase of the design procedure. Correspondingly, during the detailed design phase in the procedure, the most important factors are "low-EI material" (0.195), "orientation" (0.176), "building relationship" (0.158), and "energy-saving material" (0.107). The findings stress the significance of architectural programming and passive design for wider acceptance of low-EI housing in the tropics.

“…Segundo os autores, numa perspectiva a longo prazo, as emissões e CO 2 serão muito mais afetadas pelo mix energético do país. Azzouz et al (2017) fez uma avaliação do ciclo de vida (do berço ao túmulo) a partir de medidas de conservação de energia para um edifício de escritórios (15590 m² de área total) para o centro de Londres, numa perspectiva de 60 anos de vida útil. Para a avaliação de impacto considerou-se a energia primária (MJ) e o potencial de aquecimento global (kg CO 2 eq).…”

Agradeço a Deus, pelo dom da vida e pela força que me concedeu ao longo dessa trajetória, me guiando e me provendo paz, sabedoria e paciência, para passar por todas as etapas que me trouxeram até aqui. Agradeço aos meus pais, Rosilene e Edgard, por todo o apoio e incentivo em toda a minha vida. Deixo aqui registrado uma homenagem ao meu pai que, em todas as vezes que me levava para escola, sempre se despedia de mim dizendo "Estude bastante, para um dia ser doutora!". De alguma forma essas palavras transcenderam o tempo e para cá me encaminharam. Agradeço ao Andrey, pelo amor, carinho, apoio e incentivo em todos esses nossos anos de caminhada, o qual tão pacientemente sempre me ajuda a enxergar o lado bom de tudo (nos erros e acertos), por sempre ter junto a frase "calma, tudo vai dar certo", para que eu conseguisse alcançar meus sonhos, que na verdade, são nossos. Agradeço à minha família, irmão e irmã, cunhados e cunhadas, sobrinhas, primos e primas, tios e tias, sogro e sogra, avôs e avós (in memoriam), que sempre me apoiaram, me ensinaram (e ainda me ensinam) o que há de melhor, aceitando muitas vezes a minha ausência, para que eu pudesse chegar até aqui. Agradeço à tantos amigos que Deus colocou no meu caminho ao longo dessa trajetória de vida. Aos queridos(as)
