On August 23rd, 2025, AECORD hosted a focused online session with Mr. Deepak Kumar, a renowned Building Energy Performance Analyst, delivered an insightful session on “Regenerative Architecture – Thinking Green”. His session inspired architects, designers, and sustainability professionals to rethink the built environment as a living system one that harmonizes with nature while addressing the urgent challenges of climate change and resource depletion.
???? Why Sustainability Is Critical Today
Climate Change: Buildings are a big contributor to carbon emissions. Rising global temperatures, extreme weather, and environmental stress make sustainable building urgent.
Resource Depletion: Construction consumes vast energy, water, and raw materials. Without efficiency, we risk exhausting natural resources.
Urban Carrying Capacity: Cities are growing rapidly, straining infrastructure, air quality, and livability. Sustainability ensures balance between growth and ecological health.
???? Sustainability vs Regeneration
Sustainability: Aim is to “do less harm” → reduce impact, achieve net-zero emissions, conserve resources.
Regeneration: Goes beyond sustainability → actively restores ecosystems, gives back to nature, and creates net-positive outcomes.
???? Eight Principles of Regenerative Architecture
-
Respect Nature’s Limits → build within ecological boundaries.
-
Restore Ecology → enhance biodiversity and natural systems.
-
Systems Thinking → design buildings as part of larger ecosystems.
-
Place-Based Design → adapt to local culture, climate, and ecology.
-
Net-Positive Impact → give back more than what’s taken.
-
Circular Resource Use → reuse, recycle, and avoid waste.
-
Resilience → design for climate risks, adaptability, and long-term performance.
-
Community Co-Creation → involve people in design to build social value.
???? Building-Level Strategies
Passive Design: Natural ventilation, shading, orientation.
Sustainable Materials: Low-carbon concrete, recycled steel, bamboo, timber.
Daylighting: Maximize natural light to cut energy use.
Efficient HVAC: Smart systems reduce power consumption.
Renewable Energy: Solar, wind, biomass integration.
Water/Waste Reuse: Rainwater harvesting, greywater recycling, STPs.
????️ Indoor Air Quality & Wellness
Poor ventilation → Sick Building Syndrome (headaches, allergies, fatigue).
Healthy indoor air = essential for occupant wellness, productivity, and comfort.
???? The Economic Sense
ROI & Efficiency: Energy and water savings cut operating costs.
Market Drivers: ESG reporting, BRSR compliance push developers to adopt green/regenerative strategies.
???? Case Studies (Global + India)
Bullitt Center, Seattle: “Greenest office building in the world.”
Shanghai Tower, China: Double-skin façade, efficient energy systems.
Omega Center, USA: Net-zero and regenerative water systems.
German Project (Vauban, Freiburg): Sustainable community design.
Indira Paryavaran Bhavan, India: Net-zero energy government building.
⚠️ Challenges
O&M Inefficiencies: Poorly run STPs, neglected renewable plants.
Skill Gap: Few trained professionals in regenerative design.
Policy Gaps: Certifications often don’t push beyond “green.”
???? Retrofitting Existing Buildings
Possible with optimization: upgrading HVAC, adding renewables, water reuse, better insulation → move older buildings toward regenerative standards.
????️ Tools
IFC EDGE: Early design tool to achieve net-zero pathways cost-effectively.
???? Future Direction
Move beyond green ratings → toward fully integrated regenerative design that restores ecosystems, improves wellness, and creates social impact.
????️ In Conversation with Deepak Kumar
Q: Can regenerative design principles be adapted to retrofit existing buildings, or is it more viable for new developments?
A: Retrofitting is indeed possible, though it comes with its own set of challenges. Existing buildings can be optimized by integrating regenerative strategies such as improving energy efficiency through passive design interventions, upgrading to efficient HVAC systems, adopting renewable energy where feasible, and rethinking water and waste management systems. Material selection also plays a crucial role—switching to sustainable and low-impact materials during renovations can have a significant effect. While new developments provide a clean slate to embed regenerative principles from the ground up, retrofitting has immense potential to transform the vast stock of existing buildings that continue to consume resources and impact the environment. Even incremental changes, when scaled across multiple retrofit projects, can contribute meaningfully to broader regenerative goals.
Q: Are there any design tools or simulation software that can best model the ecological impact of regenerative strategies?
A: Tools like IFC EDGE are increasingly being used in the early stages of design to evaluate and model the performance of buildings. EDGE helps in identifying strategies that can lead towards net-zero outcomes by analyzing parameters such as energy efficiency, water usage, and embodied carbon in materials. Additionally, software platforms that integrate Building Information Modelling (BIM) with sustainability plug-ins allow practitioners to simulate and assess ecological impacts more comprehensively. These tools not only provide quantifiable data but also guide decision-making in a way that regenerative principles are embedded right from concept to execution. The use of such tools ensures that regenerative strategies are not just aspirational but are backed by measurable outcomes and verifiable performance.
