7 Essential Green Building Elements

Although the term green building has become very popular in recent years, the main question is what makes a building green.

Green buildings work because many parts come together. Components of green building reduces impact and improves comfort. Below are the seven essentials, kept simple but complete.

1) Energy Efficiency & Renewables

A green building starts with a tight envelope and smart systems. Good insulation, high-performance glazing, and air sealing reduce heat loss and gain. Efficient lighting and right-sized HVAC cut demand. Add renewables most commonly rooftop solar—to replace fossil energy.

• Typical tools: insulation upgrades, LED lighting, variable-speed drives, solar PV. 

2) Water Efficiency & Stormwater Management

Use less water indoors and manage rain outdoors. Low-flow fixtures, leak detection, and greywater reuse trim indoor use. Rainwater harvesting and permeable surfaces reduce runoff and support landscaping.

• Quick wins: low-flow taps and toilets, rain tanks, drip irrigation, permeable paving. 

3) Low-Impact, Durable Materials

Choose materials with low embodied carbon and long life. Recycled steel, certified wood, and bio-based options reduce impacts. Specify low-VOC finishes for health. When possible, verify with EPDs and prefer local supply to cut transport emissions.

• Examples often used: recycled steel, bamboo, low-carbon concrete, low-VOC paints. 

4) Indoor Environmental Quality (IEQ)

Healthy interiors are central to green design. Provide ample fresh air, filter particulates, and control humidity. Daylight and views support well-being; acoustic and thermal comfort reduce stress and boost productivity.

• Focus areas: ventilation rates, filtration, daylighting, low-emitting materials. 

5) Site & Ecology (Location, Orientation, Biodiversity)

Pick sites that cut travel and protect nature. Proximity to transit reduces car use. Orient the building for sun and wind to support passive heating and cooling. Use green roofs and native planting to limit heat-island effects and support urban ecology.

• Tactics: transit-served sites, solar-aware massing, green roofs, habitat planting. 

6) Construction & Operational Waste Reduction (Circularity)

Design to use fewer materials and generate less waste. Plan for off-site prefabrication where it helps. Reuse and recycle construction debris. In operation, separate waste streams and compost organics where feasible. Durable, adaptable design extends building life and avoids future waste. 

7) Smart Operations, Codes & Continuous Performance

What gets measured gets managed. Use building management systems and sensors to monitor energy, water, and IAQ. Commission systems at handover and re-commission periodically. Align with energy codes and voluntary rating systems to keep performance on track over time.

• Tools: BMS/IoT, fault detection, ongoing commissioning, code and rating compliance.
