Explore the principles of sustainable architecture, including green building practices, energy-efficient design, use of renewable materials, and implementing eco-friendly technologies in construction.
Sustainable Architecture – Quick Reference Notes
Sustainable architecture (also called green or eco‑architecture) designs, constructs, and operates buildings in a way that minimizes environmental impact, conserves resources, and promotes the health and well‑being of occupants over the building’s entire life cycle.
| Issue | Architectural Impact | Sustainable Response |
|---|---|---|
| Climate change | Buildings account for ~40 % of global energy use & 30 % of CO₂ emissions. | Reduce energy demand, use low‑carbon materials. |
| Resource depletion | Extraction of concrete, steel, timber, and water. | Choose renewable, recycled, or locally sourced materials; implement water‑saving systems. |
| Urban heat islands | Dense, impermeable surfaces raise city temperatures. | Green roofs, reflective façades, vegetation. |
| Human health | Poor indoor air quality, inadequate daylight. | Passive ventilation, non‑toxic finishes, daylighting. |

| Metric | What It Measures | Typical Target |
|---|---|---|
| Energy Use Intensity (EUI) | kWh/m²·yr of operational energy | < 30 kWh/m²·yr (net‑zero goal) |
| Embodied Carbon | CO₂e per kg of material or per m³ of building | < 150 kg CO₂e/m³ (varies by typology) |
| Water Use Intensity (WUI) | Liters per occupant per day | < 50 L/occupant·day |
| Indoor Environmental Quality (IEQ) | Air quality, daylight, acoustic comfort | Meets WELL/LEED IEQ credits |
| Thermal Comfort | PMV (Predicted Mean Vote) range –0.5 to +0.5 | Achieved through passive & active systems |
