Green architecture: An overviewÂ
Green architecture prioritises sustainability, aiming for minimal environmental impact. This approach, crucial in developing economies like India, benefits the planet and offers significant energy savings. According to TERI, if all Indian urban buildings embraced green concepts, the country could save over 8,400 megawatts annually to power 550,000 homes.
Features
Green architecture doesn’t adhere to specific requirements but aims for sustainability. Common features include:
- Energy-efficient lighting and appliances
- Water-saving plumbing fixtures
- Green roofs and native landscaping
- Minimal harm to natural habitat
- Use of renewable energy sources
- Non-toxic, eco-friendly materials
- Adaptive reuse of older buildings
- Efficient space utilisation
- Rainwater harvesting and grey-water reuse
What enables a building to be green?
Features of the building
Prioritise on-site production to reduce energy consumption.
Reuse and recycling
Incorporate materials from previous projects to minimise environmental impact.
Managing water supply
Utilise rainwater harvesting and water treatment systems.
Nature centre of design
Integrate greenery for proper ventilation and reduced CO2 levels.
Energy efficient
Use HVAC modelling, electrical services and solar panels for energy conservation.
Effective facade designs
Utilise veneers and BIM tools for ecological structure maintenance.
Advantages
Green architecture brings numerous benefits:
Energy savings
Significant reduction in energy consumption.
Intelligent energy integration
Green architecture emphasises incorporating renewable and low-carbon technologies during design and construction. It includes orienting buildings strategically to harness natural efficiency by utilising diversified local energy sources like solar and geothermal.
Water efficiency strategies
Green architecture minimises water waste through efficient plumbing fixtures and innovative systems. It explores methods for improving water efficiency, utilising rainwater harvesting and reducing overall water consumption in buildings.
Sustainable material utilisation
Using green building materials ensures the conservation of natural resources, reducing environmental impacts across a building’s lifecycle. In India’s growing construction sector, these materials maximise social and economic value from design to demolition.
Resilient and adaptable structures
Green buildings are designed to withstand disasters, using durable, low-carbon input materials. Their flexibility anticipates changing needs reducing the necessity for demolitions or major renovations over time.
Effective waste management
A crucial aspect of green architecture is a responsible waste management system, minimising environmental impact throughout a building’s lifestyle. It includes strategies to reduce pollution, recycling solid waste and managing wastewater effectively.
Enhanced indoor environmental quality
Green architecture improves indoor environments through proper ventilation, creating floor plans, natural light and non-toxic materials. IEQ assessment focused on tangible and intangible elements, improving residents’ quality of life, health and well-being.
Urban green spaces
Green architecture extends beyond individual buildings to create green spaces in urban areas. It enhances aesthetics, promotes biodiversity, reduces pollution, retains rainwater and mitigates carbon emissions.
Interactive community development
infrastructure projects in green architecture prioritise creating interactive spaces to foster social and economic revitalisation. The blend of advanced technologies with ecological considerations aims to optimise shrinking spaces for positive community experiences.
Financial benefits
Green architecture ensures financial benefits for residents, including high property values. The low operational cost, thanks to minimal energy usage, makes it an economically viable and sustainable choice.
Long-term cost savings
Initial investment pays off through lower energy and maintenance costs.
ChallengesÂ
While enticing, green architecture has challenges:
High initial cost
Eco-friendly materials can be expensive.
Construction time
Longer construction duration due to environmental considerations.
Lack of conventional systems
Absence of immediate cooling systems like air-conditioners.
Regional limitations
It is not only feasible in some areas, especially those with limited renewable energy sources.
Advancements in green architecture
The evolution of green architecture brings forth innovative approaches to sustainable home design. Notable progress includes Net-Zero Energy Buildings, which maintain an equilibrium by generating as much energy as they consume. Passive House Design prioritises energy efficiency through insulation, airtightness and passive solar heating. Living Roofs, featuring greenery, offer insulation, mitigate stormwater runoff and introduce green spaces in urban settings. Smart Building Technologies, integrating intelligent lighting and climate systems, optimise energy consumption and enhance occupant comfort. Biophilic Design, emphasising natural elements, establishes a connection with nature and contributes to improved mental well-being.
Does green architecture have an opportunity in India?
India is actively embracing sustainable architecture, with a 10 billion sq ft green building footprint targeted by 2022. Notably, around 14 lakh houses, covering 6.33 billion sq ft, have adopted the ‘green building’ tag. Recognising its importance, top real estate firms are joining the green movement, supported by the Indian Green Building Council. Currently third in LEED rankings, India proves green architecture is feasible and profitable. With advancing technology, sustainable living options will become more affordable, making green architecture a practical step towards reducing carbon footprints.
