  • This includes reducing energy consumption, promoting resource conservation, and minimizing waste generation.
  • Key practices include implementing green building standards utilizing renewable energy sources and adopting sustainable materials.

• Economic Sustainability: Ensures financial viability of projects and buildings throughout their lifecycle.

  • It involves cost-effective design and construction, maximizing operational efficiency, and creating long-term value.
  • Strategies include incorporating energy-efficient systems and pursuing sustainable financing options.

• Social Sustainability: Prioritizes enhancing quality of life for individuals and communities.

  • This includes promoting inclusivity, accessibility and equity.
  • Key considerations include affordable housing, accessible public spaces, and fostering community engagement.

Life Cycle Thinking

• Design and Construction: Minimizes environmental impact of material extraction, manufacturing and transportation.

  • Sustainable practices include selecting eco-friendly materials, optimizing construction methods, and reducing waste.

• Operation and Maintenance: Focuses on reducing energy and water consumption, managing waste and ensuring occupant health and well-being.

  • This phase involves incorporating energy-efficient systems, implementing water conservation, and optimizing building maintenance schedules.

• Decommissioning and End-of-Life: Minimizes environmental impact of demolition and waste disposal.

  • Sustainable practices include maximizing material reuse and recycling, minimizing landfilling, and emphasizing circular economy principles.

Resilience and Adaptability

• Climate Change Adaptation: Designing buildings and urban spaces to withstand impacts of climate change, such as extreme weather, rising sea levels, and heat waves.

  • This approach includes implementing flood-resistant design, green roofs, stormwater management, and passive cooling techniques.

• Disaster Resilience: Ensuring buildings and infrastructure can withstand natural disasters such as earthquakes, hurricanes and wildfires.

  • This involves adopting seismic design principles, incorporating hurricane-resistant materials, and implementing wildfire mitigation strategies.

• Societal Change: Designing adaptable spaces that can evolve to meet changing societal needs, including demographic shifts, technological advancements and evolving work patterns.

  • Implementing flexible design principles, incorporating smart technology for management and accessibility for all users.

Circular Economy in the Built Environment

• Waste Minimization: Adopting design and construction methods minimizing waste generation.

  • This includes using prefabricated components, employing modular construction, and prioritizing material reuse and recycling.

• Material Recycling and Upcycling: Reusing and repurposing construction waste and other materials for new construction projects.

  • This includes incorporating recycled aggregates, reclaimed wood, and recycled steel.

• Regenerative Design: Creating buildings and spaces that contribute positively to the environment.

  • This includes integrating renewable energy systems, promoting biodiversity, utilizing bio-based materials which decompose naturally.

Efficient Building Design

• Efficient Building Design: Incorporating passive design strategies like natural lighting, ventilation, and insulation to reduce energy consumption.

  • Optimization of window placement, cross-ventilation and selecting high-performance insulation.

• Renewable Energy Integration: Installing solar panels, wind turbines or geothermal systems to power buildings sustainably.

  • Site specific conditions should be considered when optimizing the size and placement of these systems.

• Smart Energy Systems: Utilizing IoT and AI to monitor and optimize energy usage in real-time.
