“…The role of the designer in designing the building has a strategic influence in reducing the overall energy, especially the energy efficiency of the mechanical and electrical systems used during the operation of the building [26]. Besides, an energy life cycle approach to construction projects in designing buildings that prioritize energy efficiency and are environmentally friendly will directly impact environmental sustainability [27]. This research is in line with the results obtained where the initiation and design phases will significantly contribute to efforts to minimize energy consumption during the construction and operational phases of a building.…”

The construction industries had a significant role as emission gas contributors through direct activities, such as the construction process, the operation and demolition of the building, and indirect activities, which is the designing process to decide the types of materials and the shapes of the building. This paper aimed to create an embodied and operational energy assessment concept based on a project life cycle using qualitative methods through a research questionnaire. In the questionnaire, there were 18 indicators based on a literature review relating to embodied and operational energy within the scope of the project life cycle (initiation, design, construction, and operation). Indicator assessment used a Likert scale and was analyzed by Structural Equation Modeling Partial Least Squares. Respondents in this study include consultants, contractors, and stakeholders. The results of the study showed a significant relationship between the initiation and design phases of the construction phase and the operational phase to minimize energy. Stakeholder commitment to the environment and planning that prioritizes energy efficiency (embodied and operational energy) had the highest T-Statistic values of 100.479 and 61.581 with a 95% confidence level. This showed the role of stakeholders and designers is crucial to the reduction in energy embodied and operational during the project life cycle, so that awareness and commitment are needed in realizing green construction.

Small type houses answer the need for residential housing in sub-urban areas. The increasing price of land and the affordability of buyers has encouraged the production of small type residential houses to increase. Small type residential houses have a land area of ≥ 90 m2 and a building area of ≥ 36 m2. However, small type residential houses do not fully answer space needs. Small residential houses tend to undergo renovation to meet space needs. This research uses quantitative descriptive methods. This research aims to formulate a pattern for renovating small residential houses using the case study of the Jasmine Cluster, Sawangan, Depok. This research is necessary considering that during the pandemic, homes are the safest areas for quarantine and as a means of self-isolation for those who are infected. The pandemic event has become a valuable lesson, especially for getting a healthy home. Efforts to fill the space in small type houses in the Jasmine Cluster are carried out by renovating the houses vertically and horizontally. The development was carried out because the existing space does not meet needs. Factors that influence the development of this residence are the number of family members and other rooms that are not provided by developers of small type residences. The density levels before and after renovation show significant changes, and become alternative solutions (quarantine and isolation) as a response to future pandemics.

“…Preview research has addressed the Social Sustainability (SS) on the built environment [13]- [17], but there is a lack of knowledge about the impact of the stages of the life cycle of a building on the accomplishment of Sustainable Development Goals (SDGs) and human rights, particularly in the emerging economies, and a need for social sustainability guides for decision-makers. Assuming that all human activity has the responsibility and capacity to contribute to the achievement of the SDGs and the fulfilment of Human Rights, the purpose of this research was to identify socioeconomic sustainability criteria on developing countries, specifically México, and systematize them as a guide for practitioners in the stages of planning, design, and build, as frameworks on the sustainable architecture practice are an essential factor to ensure sustainable development in multiple dimensions [18].…”

Sustainability is based on three pillars: social, economic, and environmental. However, the main systems of evaluation of the sustainable building, such as Building Research Establishment Assessment Method (BREEAM) and Leadership in Energy and Environmental Design (LEED), have a strong burden towards the environmental aspect, neglecting the social and economic, and underestimating the effects of the building projects on reducing poverty and inequity. The purpose of this research was to identify socioeconomic criteria for the reality of developing countries, specifically México, and systematize them in a conceptual framework for the stages of planning, design, and construction of buildings with a focus on Sustainable Development Goals (SDGs) and human rights. Through semi-structured interviews with experts and surveys, 12 criteria were identified and ranked for the planning stage, 19 for the design stage, and 15 for the construction stage, being especially relevant the contribution to the Sustainable cities and communities (SDG11), Decent work and economic growth (SDG8) and Reduced inequalities (SDG10) goals. It was found that projects considered sustainable were required to have clear policies on the issues of labor rights, social inclusion, zero tolerance for corruption, gender perspective, and prevention of damage to community environmental assets. The criteria identified contribute to the knowledge of social and economic sustainability in developing countries and aim to make those involved aware of the significance of their decisions in the different stages of the life cycle of construction projects.
