Sustainable design is integral to modern architecture, aligning environmental responsibility with occupant comfort and operational efficiency.
The provides a comprehensive framework for sustainability.
Here are key design considerations based on its principles:
Efficient energy use reduces operational carbon footprint and energy costs.
Building Envelope: Optimize RETV (Residential Envelope Thermal Value) and ETTV (Envelope Thermal Transfer Value) with low U-values for walls and windows, and incorporate sunshading devices.
Active Systems: Use energy-efficient ACMV (air conditioning and mechanical ventilation) systems, and aim for zero/positive energy buildings.
Renewable Energy: Integrate on-site solar panels or other energy generation systems.
Daylighting and Natural Ventilation: Design for optimal daylight access and cross-ventilation, using strategic building orientation and layouts.
Address the full lifecycle impact of materials and construction.
Embodied Carbon: Select sustainable materials and reduce carbon-intensive processes.
Concrete Usage Index: Minimize traditional concrete use by adopting green concrete or recycled concrete aggregates.
Sustainable Systems: Opt for prefabrication, modular construction, and Mass Engineered Timber (MET) for reduced waste and emissions.
Enhance the building's adaptability to environmental challenges.
Urban Heat Island (UHI) Mitigation: Use reflective materials, green roofs, and high-albedo finishes.
Green Plot Ratio: Maximize greenery with native plants, vertical gardens, and green roofs.
Circularity: Incorporate waste management systems and facilities for composting and recycling.
Leverage technology for smarter, more efficient buildings.
Active Demand Control: Install systems to adjust energy usage based on demand.
Digital Twin: Use digital models for efficient facility management and predictive maintenance.
Energy Monitoring: Provide dashboards for real-time tracking of energy consumption.
Design for occupant comfort and wellness.
Indoor Air Quality: Use low-VOC materials and ensure effective ventilation systems.
Acoustics: Incorporate noise mitigation measures for occupant comfort.
Green & Blue Spaces: Provide access to nature, such as gardens or water features, and ensure proximity to parks or green corridors.
Mobility: Include bicycle racks, end-of-trip facilities, footpaths, and spaces for inclusive activities.
Ensure buildings are easy to maintain over their lifespan.
Design with safe and accessible maintenance zones, such as walkways on rooftops or accessible service shafts.
Use durable, low-maintenance materials to minimize lifecycle costs and disruptions.
Sustainable design is a multifaceted approach that integrates energy efficiency, material consciousness, resilience, intelligence, occupant wellbeing, and maintainability.
By adopting the framework, architects can create buildings that are not only environmentally responsible but also adaptive, comfortable, and efficient for long-term use.
