In the heart of South Africa’s construction industry, a groundbreaking study is set to redefine how sustainable building projects are delivered. Led by Chijioke Emmanuel Emere from the Department of Built Environment at Walter Sisulu University, the research, published in the journal ‘Frontiers in the Built Environment’ (which translates to ‘Frontiers in the Built Environment’), delves into the critical strategies that can drive successful sustainable building construction (SBC) projects. The findings could have significant commercial impacts, particularly for the energy sector, as the push for greener buildings gains momentum.
Emere’s study, conducted primarily in the Gauteng province, identifies three key project delivery strategies (PDS) that are essential for the success of SBC projects. These strategies—sustainable tendering and contracting, integrated project delivery, and sustainable public and private financing—represent a shift from traditional building approaches to more collaborative and environmentally conscious methods.
“The construction industry is at a crossroads,” Emere explains. “We can either continue with business as usual and contribute to environmental degradation, or we can embrace sustainable practices that benefit both the planet and the bottom line.”
The research highlights the importance of sustainable tendering and contracting, which involves selecting contractors and suppliers based on their environmental performance and commitment to sustainability. This approach not only reduces the environmental impact of construction projects but also encourages innovation and competition among industry players.
Integrated project delivery is another crucial strategy identified in the study. This method involves all stakeholders—from architects and engineers to contractors and clients—working together from the outset of a project. By fostering collaboration and communication, integrated project delivery can lead to more efficient, cost-effective, and sustainable buildings.
“When everyone is on the same page from the start, we can avoid costly mistakes and delays,” says Emere. “Moreover, this collaborative approach encourages the use of sustainable materials and technologies, which can significantly reduce a building’s energy consumption and carbon footprint.”
The third strategy, sustainable public and private financing, emphasizes the need for financial incentives and support for SBC projects. This can include government subsidies, tax breaks, and green financing options that make sustainable building more accessible and affordable.
The implications of this research are far-reaching, particularly for the energy sector. As buildings account for a significant portion of global energy consumption, the adoption of sustainable building practices can lead to substantial energy savings. Furthermore, the integration of renewable energy sources, such as solar and wind power, into building design can further reduce energy demand and promote a more sustainable energy future.
Emere’s study also underscores the need for a coordinated, cooperative, and strategic effort among researchers, industry experts, and policymakers. By prioritizing these principal project delivery factors, stakeholders can work together to identify improvement initiatives and actualize successful SBC project delivery.
As the construction industry continues to evolve, this research serves as a roadmap for a more sustainable future. By embracing these critical project delivery strategies, South Africa—and indeed the world—can build a greener, more energy-efficient built environment. The study’s findings, published in ‘Frontiers in the Built Environment’, offer a compelling case for a shift towards more sustainable, integrated, and collaborative project delivery methods. The time to act is now, and the path forward is clear.
