I help design buildings that use passive cooling, local materials, and practical research to cut energy use and make spaces comfortable without relying on heavy technology.
Pricing Guide
Net-Zero Residential Architecture & Strategy
Core Design & Energy Strategy
- Passive Solar Layout: Custom floor plans oriented to maximize winter sun and block summer heat, aiming for 70% natural daylighting.
- Ventilation Systems: Design of central courtyards ("The Lungs") for stack-effect ventilation to reduce reliance on AC.
- Net-Zero Modeling: Computer simulations to optimize the building envelope for near-zero electricity standards.
Structural Innovations
- Earth Block Technology: Specifications for using excavated basement soil to create Compressed Stabilized Earth Blocks (CSEB) for walls.
- Bubble Deck Slabs: Structural drawings incorporating recycled plastic balls into concrete to reduce dead weight and material costs.
- Insulation Specs: Detailing for AAC blocks and reflective roof tiles to reject solar heat gain.
Aesthetic Features
- Heritage Upcycling: Integration of reused elements like Haveli doors/windows and precast wall niches ("Aala") to save brick usage.
- Custom Shading: Drawings for movable perforated screens ("Jaalis") and bamboo pergolas for balconies.
- Passive Cooling: Design of low-energy evaporative cooling features like trickle fountains.
Facade Retrofit & Passive Cooling Design
Envelope Optimization
- Thermal Analysis: Study of wall/roof thermal transmittance (U-values) with recommendations for insulation materials like Vermiculite.
- Cool Roof Design: Specifications for reflective mosaic tiles or green roof integration to reduce top-floor heat gain.
Shading Systems
- Custom Screen Design: Fabrication drawings for manual sliding or folding perforated screens (metal/stone) to block harsh sunlight.
- Louver Systems: Design of rotating vertical louvers for south-facing facades to control light entry.
- Fenestration Audit: Selection of high-performance glass or double-glazing units based on orientation.
Natural Ventilation
- Convective Loops: Design of clerestory windows and vents to flush out hot air at night.
- Glare Control: Strategies to prevent direct glare while maintaining natural daylight levels.
Institutional Sustainable Masterplanning
Site Planning & Climate Control
- Micro-Climate Orientation: Layout strategy ensuring mutual shading of buildings and wind tunnel optimization for outdoor thermal comfort.
- Urban Regeneration: Landscape strategies to restore local biodiversity and regenerate soil quality.
- Disaster Resilience: Structural prototyping for specific zones, such as elevated pile foundations for flood risks.
Water & Energy Infrastructure
- Hydrological Design: Engineering of causeways, check-dams, and retention ponds to impound rainwater and recharge the water table.
- Renewable Integration: Strategic placement of Solar PV arrays to handle 50-100% of campus energy load.
- Centralized Cooling: Planning for low-energy cooling solutions like earth air tunnels.
Implementation Framework
- Material Rulebook: Guidelines for using local materials (like quartzite) to minimize transport and construction waste.
About Green Building Consulting & Research
Why I Do This Work
Architecture, for me, means creating spaces that feel good now and in the future. I’m not interested in just putting up walls - I want buildings that bring khushali (well-being) and work with nature, not against it.
How I Think About Green Building
- Holistic sustainability is my starting point. It’s about balancing social needs, resource use, and cost, not just chasing energy ratings.
- Climate-responsive architecture matters. I study the local climate and use design tricks for comfort, rather than relying on heavy tech.
- I keep pushing for thoughtful innovation - finding materials and techniques that actually cut down our impact.
What I Actually Do
- My consulting is built on years of practical research. I use passive building design strategies, like courtyards for airflow, evaporative cooling, and smart shading (think chajjas and jaalis) to keep buildings comfy without AC.
- For net-zero energy buildings, I focus on insulation and rooftop solar, aiming for homes that barely need outside electricity.
- I’m big on sustainable construction materials. If we dig earth for a basement, why not use it for wall blocks? I reuse old doors, windows, anything with a story. Bubble Deck Slab technology is another favorite - it saves concrete and weight.
Research That Helps Communities
- My team and I have built guides for affordable green housing, created design handbooks for energy-efficient homes, and even made tools like econiwas.com for everyone to use.
- Whether it’s a disaster shelter in the Sundarbans or urban regeneration through green design for Delhi’s tight spaces, I try to solve real problems with practical solutions, using local materials and ideas people can actually build themselves.

My Story
We’ve been at this since 1980, but really, the roots go way back. I grew up in a big, wild house – always climbing, always discovering new corners. That’s what I want for others too. Whether it’s a home for street kids or a sprawling university, it’s got to feel alive, in sync with nature. Cities keep getting tighter, so we started treating rooftops as new ground – gardens, solar panels, places to meet. It’s about comfort, and building something that lasts.
My Work
Sustainable and Passive Architecture - We design low-energy buildings for homes, campuses, and city projects using passive cooling architecture.
Local Materials and Recycled Elements - We use site soil for walls, recycled jharokha windows, and always ask—what’s more sustainable than this?
Future-Proof Homes - With insulated walls, solar panels, and smart ventilation, our future-proof homes keep your bijli ka bill (electricity bill) super low.
Courtyard House Design - Courtyards bring in light and air, inspired by havelis, making spaces cooler and more connected to nature.
Art in Architecture - Hand-painted louvers, custom jaalis, and artful touches make our buildings joyful, not just functional.
