As urban populations continue to swell, the imperative to harmonize housing growth with sustainability becomes increasingly urgent. In many cities, the unchecked expansion of housing infrastructure exacts a heavy toll on the environment, depleting natural resources, exacerbating pollution levels, and encroaching upon vital ecosystems. Achieving a balance between meeting the burgeoning housing demand and preserving environmental integrity necessitates innovative approaches and stringent regulations. Sustainable urban planning initiatives, such as promoting mixed-use development, prioritizing green building practices, and investing in public transportation infrastructure, offer promising avenues for mitigating the ecological footprint of urban expansion. Moreover, fostering community engagement and incorporating principles of social equity into housing policies are crucial for ensuring that sustainable development efforts are inclusive and equitable. By embracing a holistic vision that integrates environmental stewardship, social responsibility, and economic viability, cities can pave the way for a future where housing growth serves as a catalyst for sustainability rather than a threat to it.

A recent article explores the increasing importance of the construction sector in implementing PMAY and its role in contributing to greenhouse gas emissions. It emphasizes the need to address and reduce the environmental impact associated with construction activities.
Modern Technologies in the Housing Sector
- PMAY Mission and Light House Projects
- Light House Projects (LHPs) under PMAY use modern technologies like Mivan construction and Insulating Concrete Formwork for faster, resilient, and affordable housing.
- Global Housing Technology Challenge-India (GHTC-India) aims to incorporate sustainable and disaster-resilient global housing technologies.
- Mivan Construction Technology
- Utilizes advanced aluminium formwork for faster and eco-friendly construction, surpassing traditional methods.
- Recyclable and reusable, it reduces environmental impact and construction wastage.
- Insulating Concrete Formwork (ICF) Technique
- Uses double-walled polystyrene panels filled with concrete for strong, durable structures.
- Provides excellent insulation for heat and sound, maintaining steady thermal mass energy.
- Hybrid Concrete Construction
- Combines cast-in-place concrete with precast materials for accelerated construction, cost-effectiveness, and quality control.
Sustainability Concerns in Housing Development
- Issues Due to Construction Technologies
- Thermal Distress: Inadequate insulation leading to increased heat gain.
- Elevated GHG Emissions: Insufficient insulation causing higher electricity consumption.
- Increased Electricity Consumption: Use of lower efficiency appliances contributing to greenhouse gas emissions.
- Challenges in Housing Projects
- Locational Factors: Lack of master plans in census towns affecting housing projects.
- Inadequacies in Building Typology: Dense, high-rise developments impacting sustainability.
- Excessive Reliance on Centralized Systems: Overburdened infrastructure lacking sustainability provisions.
- Inefficient Beneficiary-Led Construction
- Approximately 63% of PMAY-U projects self-constructed by beneficiaries.
- Lack of adherence to building norms and safety codes, requiring improved sustainability integration.
- Lack of Awareness and Multi-Stakeholder Nature
- Implementing passive designs faces challenges due to complex stakeholder involvement.
- End-users’ lack of awareness hinders adoption, emphasizing the need for increased collaboration.
Steps for a Sustainable Housing Sector
- Prioritizing Thermal Comfort
- Integrating passive design strategies for thermal comfort in vulnerable communities.
- Reinforcing building codes like Eco Niwas Samhita for improved indoor thermal comfort.
- Raising Awareness About Passive Designs
- Encouraging ecosystem change for adoption of passive designs.
- Incentivizing developers to prioritize and implement passive design codes.
- Promoting Green Buildings
- Enhancing policies to increase ‘Green Buildings’ share in the market.
- Potential reduction of national power demand by 25% in 2030 through improved energy efficiency.
- Initiating Location-Tailored Projects
- Conducting socio-economic surveys for understanding livelihood patterns.
- Zoning-based inclusion for affordable housing in strategically suitable locations.
- Robust Layout and Building Design
- Enforcing efficiency criteria for envelope design and shading devices.
- Implementing guidelines like Eco Niwas Samhita for a sustainable envelope design.
Conclusion
- The interim Budget 2024’s focus on housing is crucial for ‘Housing for All.’
- Balancing trade-offs between quality of life, environment, and sustainable practices is imperative.
- Collaborative efforts and incentivization are needed for a shift towards sustainable housing.
- An environmentally-conscious approach will create resilient structures and models of sustainability for an inclusive future.
