“…In parallel, the Specific Weight (SW) and the Specific Embodied Energy (SEE) value of each material found in the forty samples was established with the use of bibliography [13,23,26,27,35,36,38,[43][44][45][46][47][48][49][50][51][52]. These values and their respective sources are specified in Database 01.…”

“…In India, a building with a load-bearing stone masonry wall construction system has an STEE of around 1.20 GJ/m 2 , while a building with a reinforced concrete structure with burnt brick masonry is around 4.00 GJ/m 2 [6]. In Brazil, in typical constructions made of reinforced concrete and structural masonry, the STEE value is around 1.50 GJ/m 2 [13]. In Dutch dwellings with an insulated envelope, the STEE goes from 3.0 to 6.4 GJ/m 2 [14].…”

This article presents the Specific Total Embodied Energy (STEE) and Specific Total Weight (STW) of 40 Andean residential buildings in Ecuador, from 1980 to 2020. Firstly, the BoM of ten buildings of every decade was obtained through field work carried out in three urban sectors of this city. Secondly, the specific embodied energy and specific weight of every material found in the 40 samples were obtained by bibliography. Finally, the calculation of each building was divided into three components: Structure, Envelope and Finishes. The analyzed data show a detailed collection of different materials and construction typologies used in these four decades, and the impact on their embodied energy and their weight. Moreover, this article gives a Specific Embodied Energy and Specific Weight database of 25 materials that are extensively used in Andean regions. The results show several changes in reference to the insertion of new material, but also regarding the adoption of new architectonic models. The most important changes, in the analyzed period, have been the use of concrete and metal in the structure instead of wood, the increase in the glass surface in the envelope, and the replacement of wood by particleboard on the finishes. In conclusion, the STEE of the entire building has experienced an increase of 2.19 times in the last four decades. The STW value has also increased, but to a lesser extent (1.36 times).

“…Therefore in future structure EE is going to play a more important role. [32] and *** [34] The cellular structure of wood and its low density provide a low thermal conductivity (k) with a range of values between 0,12-0,22 W/(m•K) which are much closer to insulation materials (0,035-0,100 W/(m•K)), while other building materials, such a concrete, steel and brickwork present much higher values (2,5 W/(m•K), 50 W/(m•K) and(0,45-0,65 W/(m•K) [4], thus requiring the use of insulation. Therefore timber possesses insulation properties which operate well when the thickness of wood is adequate, as manifested clearly in the case of log-homes.…”

Wood is the only natural renewable building material, produced by photosynthesis. It has the ability to preserve the stored carbon in its molecular structure as long as it remains within a structure. Timber dwellings are re-gaining recognition worldwide, especially in remote areas due to their aesthetic superiority, durability and harmony with the natural landscape. Research findings, as well as industrial operations indicate that timber buildings present beneficial environmental impacts, compared to other common building materials. Specifically, timber has substantial strength characteristics, low embodied energy, less CO2 emissions and also an easy and fast construction, combined with minimum disruption to the environment. Moreover, timber buildings have a high potential to reduce waste at site and ability for re-use, when designed for future ease of deconstruction, providing the repeated utilization of the used material, known as, the cascading concept. It is already recognized that successful waste management is a measure towards the containment of climate change. Using timber structures enhances the chances to accomplish the contemporary waste hierarchy concept, which can be implemented according to the application of Design for Deconstruction and Reuse (DfDR) concept, at an early stage. These waste management techniques are strongly related to circular economy, but can only be achieved through the aim of a long-lasting design. Finally, in most countries, the existing building codes should be revised in order to overcome the imposed limitations on the re-use of building materials.

“…Oleh karena itu sektor konstruksi dan bangunan diharapkan mampu memperbaiki keadaan dengan menjunjung prinsip keberlanjutan melalui penggunaan material yang ramah lingkungan. Pemilihan material bangunan ramah lingkungan dapat dianalisis berdasarkan penggunaan energi yang digunakan untuk proses produksinya, akan lebih baik jika memilih material yang menggunakan energi sesedikit mungkin dalam proses produksinya (Gonzalez et al, 2014). Oleh karena itu kriteria pemilihan material bangunan yang ramah lingkungan dapat dikaji berdasarkan energi produksinya.…”

In building design, the selection of building materials is one aspect that needs to be considered. Building materials are components that require energy in the manufacturing process. In the process of building material production, the use of energy at each stage becomes one of the parameters of CO2 carbon emission levels. The higher the use of fossil energy, the higher the CO2 emissions and the risk of causing global warming. Bricks, concrete blocks, and lightweight bricks are the types of materials commonly used to make building walls. The selection of wall materials is still largely related to price or aesthetic considerations, but the assessment of the level of environmental friendliness is still lacking in attention. This study tries to analyse the life cycle of energy in wall materials (bricks, concrete blocks and lightweight bricks). From the research results obtained, concrete block is the lowest material in the use of production energy.
