“…The six-month period outcomes for the winter and summer seasons are taken to find the best case in reducing operational energy with more thermal comfort in a building. In another study, Kumar et al [19] investigated low embodied energy sustainable building materials and technologies to reduce the total LCE of buildings to maintain sustainability. Kumar et al [20] tested insulation material in buildings as it is regarded as one of the most efficient methods of achieving energy savings in buildings.…”

Buildings are accountable for waste generation, utilization of natural resources, and ecological contamination. The construction sector is one of the biggest consumers of resources available naturally and is responsible for significant CO2 emissions on the planet. The effects of the buildings on the environment are commonly determined using Life Cycle Assessments (LCA). The investigation and comparison of the Life Cycle Ecological Footprint (LCEF) and Life Cycle Energy (LCE) of five residential buildings situated in the composite climatic zone of India is presented in this study. The utilization of resources (building materials) along with developing a mobile application and a generic model to choose low emission material is the uniqueness of this study. The utilization of eco-friendly building materials and how these are more efficient than conventional building materials are also discussed. In this investigation, the two approaches, (a) Life Cycle Energy Assessment (LCEA) and (b) Life Cycle Ecological Footprint (LCEF), are discussed to evaluate the impacts of building materials on the environment. The energy embedded due to the materials used in a building is calculated to demonstrate the prevalence of innovative construction techniques over traditional materials. The generic model developed to assess the LCEA of residential buildings in the composite climate of India and the other results show that the utilization of low-energy building materials brings about a significant decrease in the LCEF and the LCE of the buildings. The results are suitable for a similar typology of buildings elsewhere in different climatic zone as well. The MATLAB model presented will help researchers globally to follow-up or replicate the study in their country. The developed user-friendly mobile application will enhance the awareness related to energy, environment, ecology, and sustainable development in the general public. This study can help in understanding and thus reducing the ecological burden of building materials, eventually leading towards sustainable development.

“…This result aligns with the insights provided by Hussain and Kamal (2015), who highlighted the significance of using materials that minimise environmental impacts and pose minimal risks to human health. Such materials as timber and alternative lumber, composite bricks, cellular lightweight concrete blocks and so on (Wang and Adeli, 2014;Kumar et al, 2015).…”

“…Using sustainable structural materials minimises environmental impacts, reduces the use of resources, is cost-effective and poses no or low human health risks (Hussain and Kamal, 2015). Sustainable structural materials include timber and alternative lumber, composite bricks, composite blocks, cementitious materials, reinforced concrete/masonry alternatives and so on (Wang and Adeli, 2014;Kumar et al, 2015). For instance, Wang and Adeli (2014) recommend wood to be used as a reuse and innocuous item in low-rise buildings.…”

Purpose Successful project delivery for sustainable building construction (SBC) has been linked to certain features. Previous studies have emphasised the need to improve SBC practice in South Africa. The purpose of this study is to explore the SBC features for project delivery in South Africa. Design/methodology/approach A structured questionnaire elicited the primary data from 281 built environment professionals, mainly in South Africa’s Gauteng province. Descriptive and inferential statistics were used for the data analysis. This study used the principal component analysis technique to ascertain the principal SBC features. Findings Three components of SBC features, namely, sustainable resource use and compliance, sustainable waste minimisation and recycling and sustainable designs and materials, were developed from the principal component analysis. The factor loadings of the constituent variables ranged from 0.570 to 0.836. The reliability of each component was evaluated, and the results were 0.966, 0.931 and 0.913. Practical implications The revelations from this study will aid the decision-making of the relevant stakeholders towards establishing improvement initiatives and mitigating the reluctance to shift from conventional building methods and poor knowledge sharing of SBC benefits. Originality/value This is one of the most recent South African studies that sheds light on the components of a successful SBC deployment. The findings of this study added to knowledge by confirming three fundamental features of SBC. This study recommends adequately considering the principal features for successful SBC project delivery in South Africa.

The research work aims at developing a framework for assessing the energy efficiency of the emerging alternative materials and construction techniques in the housing sector. The scope of the study is limited to Delhi NCR region for the ease of collection of data and contacting the experts. Established and emerging alternative materials and techniques have been identified from the literature. Experts’ opinion has also been sought to see the prevalence of their use in the region. Energy efficiency parameters have been outlined from the literature and through responses of the experts. The present research work is in process and the findings shared here are preliminary results of an ongoing experts survey. The development of the framework is to help the building design professionals in taking informed decision regarding energy efficiency of the emerging alternative building materials and construction techniques and its impact on the environment.
