1Policy and regulations for residential houses often consider the physical system alone and tend to 2 focus on the energy performance of the building. This ignores the effect of occupants' everyday 3 practices and their interaction with the building technologies. This research applies practice 4 theory and the concept of system of practice to eight Australian homes with the objectives of 5 providing a deeper understanding of the complexities of the home system as well as providing 6 approaches to enable (rather than persuade) resource reduction. The homes were investigated 7 through explanatory design mixed methods which combined results of one year of longitudinal 8 quantitative data collection and home occupant interviews. The results revealed that practices are 9 performed in a sequential temporal spectrum as part of a routine and are influenced by 10 interlocked practices as well as interlocking routines from other home occupants. Practices also 11 follow established daily patterns reflected by a frequency distribution curve where the standard 12 deviation reflects the degree of habituality of the practice. Highly interlocked practices with a 13 high degree of habituality are challenging to affect. However, automation could enable resource 14 intensive activities to be dis-interlocked from an established routine and make change within the 15 home system of practice easier and more flexible. 16

“…Annual GHG emissions for case study buildings in the current study vary between 10.957 and 11.49 t CO₂ eq/year and is slightly higher than Lawania and Biswas [68,72] (9.4 t CO₂ eq/year). This is mainly due to differences in parameters like service life and climatic conditions affecting use stage GHG emissions.…”

Impact of Service Life on the Environmental Performance of Buildings

The environmental performance assessment of the building and construction sector has been in discussion due to the increasing demand of facilities and its impact on the environment. The life cycle studies carried out over the last decade have mostly used an approximate life span of a building without considering the building component replacement requirements and their service life. This limitation results in unreliable outcomes and a huge volume of materials going to landfill. This study was performed to develop a relationship between the service life of a building and building components, and their impact on environmental performance. Twelve building combinations were modelled by considering two types of roof frames, two types of wall and three types of footings. A reference building of a 50-year service life was used in comparisons. Firstly, the service life of the building and building components and the replacement intervals of building components during active service life were estimated. The environmental life cycle assessment (ELCA) was carried out for all the buildings and results are presented on a yearly basis in order to study the impact of service life. The region-specific impact categories of cumulative energy demand, greenhouse gas emissions, water consumption and land use are used to assess the environmental performance of buildings. The analysis shows that the environmental performance of buildings is affected by the service life of a building and the replacement intervals of building components.

“…In addition, the amount of materials sent to landfills is reduced, a destination that fly ash would have if not reused. In this sense, by partially replacing the cement for ready-mixed concrete with fly ash by 30-40%, an approximate saving of 25% of GHG emissions can be achieved [21].…”

Strategies to Reduce CO2 Emissions in Housing Building by Means of CDW

One of the biggest problems that human beings face is climate change and construction industry is one of the sectors causing the greatest impact, which has led him to adopt sustainable strategies. However, these have not been effective enough to reduce CO2 emissions, since solutions are required accompanied by other alternatives. Therefore, the objective of this study is to reduce CO2 by implementing CDW strategies under the following method: 1) analysis of CO2 of the major raw materials consumed, 2) use of the materials at the construction site was determined, 3) waste streams generated at the construction site were identified and those that could be reuse were highlighted, 4) CDW recycling strategies to avoid the use of the major raw materials consumption are proposed, and 5) one of the strategies proposed is further analyzed. The results show that natural aggregates generate the greater amount of CO2 due to the consumption of fuel required for their transportation. By replacing 68% of natural aggregates by recycled aggregates, CO2 can be reduced by 53%. Finally, these results can help to promote the opening of new CDW recycling companies in Nayarit and thereby contribute to the sum of sustainability practices in housing building.
