Sustainability Report

An inclusive urban design project by acau architecture

Embodied carbon

Efficient

Operational Emissions / Energy

Efficient

The key points of the project's energy approach and sustainability features are:

  • User-Centric Energy Approach: Prioritizes user needs and considers energy performance as a result of the synergy between architectural form, materials, technical systems, and usage.
  • Emphasis on Practicality: Focuses on ease of use and robust, low-maintenance technical systems.
  • Innovative Thermal Regulation: The community center utilizes geothermal probes powered by photovoltaic panels for year-round heating and cooling.
  • Natural Summer Cooling: An earth-to-air heat exchanger (Canadian well) facilitates natural ventilation for cooling during summer.
  • Energy Self-Sufficiency: The implemented energy system enables self-sufficiency for the shared spaces of the housing complex and the community center.
  • Greenhouse as Thermal Buffer:
    • Acts as a tempered circulation space in winter.
    • Fully opens in summer.
    • Preheats air during colder seasons.

Service and maintenance emissions

Efficient

Different design choices were implemented for the efficiency of the project's sustainability- 

  • Natural Ventilation in Community Center: Achieved through automatic window openings.
  • Passive Overheating Prevention: The thermal inertia of raw earth brick walls and screeds effectively prevents summer overheating.
  • Greenhouse Heat Mitigation: Shade sails are deployed in the greenhouse during summer.
  • Natural Cooling via Openings: Openable side doors and chapels in the greenhouse allow for air renewal and natural cooling.
  • Passive Winter Heat Gain: Passive heat accumulated in the greenhouse on sunny days helps reduce overall energy consumption.
  • Optimized Natural Lighting: Strategically placed and sized windows provide 50% natural lighting autonomy across most interior areas.

Afterlife

Adaptive Reuse and Flexible Design Considerations

The simplicity of the structure and dry-assembly joints allows for easy disassembly if needed. The greenhouse is designed as a highly flexible space, easily adaptable to future uses.

Disassemblable Elements for Circular Economy

 The structure and dry-assembly joints allow for easy disassembly if needed.
