Research Topic: Retrofitting for a Resilient Future: Achieving Net-Zero in Kerala Homes
My study explored the feasibility of transforming tropical residential buildings – specifically in Kerala – into net-zero energy homes through targeted retrofitting strategies. By improving the building envelope, integrating energy-efficient systems, and incorporating solar PV, the research showed remarkable results in energy savings, indoor comfort, and future climate resilience.
Key Highlights:
- Energy Efficiency: Retrofitting cut energy use nearly in half—from 8772.8 kWh to 4802.7 kWh.
- Renewable Integration: Solar PV systems generated 5250.5 kWh annually, achieving net-zero and even surplus energy in certain months.
- Thermal Comfort: Natural ventilation, ceiling fans, and shading reduced extreme indoor heat, especially in living areas.
- Climate Resilience: Despite an 84% projected energy demand increase by 2080, retrofitted homes outperformed current standards, proving their long-term sustainability.

This week, members of the DSSR Sustainability Team attended the All-Energy Conference, the UK’s largest low-carbon energy and renewables event, at the Scottish Event Campus (SEC). All-Energy is a vital date on the calendar for professionals driving the renewable and low-carbon energy transition, offering expertise, innovative technologies, and critical insights to shape a net-zero future.
For DSSR, the event was a strategic opportunity for us to:
- Stay ahead of evolving regulations (e.g., Part L updates, net-zero compliance) and discover new methods of designing future-proof buildings such as the latest heat pumps, smart grids, and energy storage systems.
- Engage with 270+ exhibitors from 14 countries, identifying technologies that can be integrated into client projects for improved efficiency and decarbonisation.
- Connect with policymakers, developers, and investors actively seeking building services expertise to deliver sustainable infrastructure, retrofits, and energy-efficient designs.
Our team explored the latest challenges and opportunities in energy transition, attending seminars on heat decarbonisation, retrofitting, and cross-sector collaboration. The insights gained will directly inform DSSR’s design strategies and client solutions, ensuring we remain at the forefront of low-carbon building innovation.
Networking and Knowledge Sharing
Senior Sustainability Specialist, Rachel Mason, and Sustainability Assistant, Atheya Rajeev, highlighted the value of All-Energy’s global networking:
Rachel Mason:
“I’ve attended All-Energy for eight years, and this year’s focus on heat networks and affordable low-carbon heating was especially relevant for our work. The event is unmatched for building partnerships—whether with technology suppliers or developers needing MEP expertise to meet sustainability targets.”
Atheya Rajeev:
“The seminar on Scotland’s Heat Transition underscored how collaboration between designers, government, and private sectors is critical to achieving net-zero buildings. As my first All-Energy, it was inspiring to see how DSSR’s work aligns with these larger industry goals.”
With 600+ speakers and record-breaking attendance in 2024, All-Energy solidified its role as the hub for renewable energy innovation. DSSR’s participation underscores our commitment to delivering sustainable, compliant, and cost-effective building designs in a rapidly evolving sector. The team is already looking ahead and applying lessons from the conference to active projects and exploring partnerships with exhibitors to enhance DSSR’s service offerings.



Shrijit receives Pick Everard Award from Loughborough University
DSSR colleague, Shrijit Sugathan, was awarded the Pick Everard Prize from Loughborough University. This is awarded to the student on the MSc Low Energy Building Services Engineering programme with the highest overall mark for their research project.
Shrijit received the highest score for his research into the potential of targeted retrofitting strategies in transforming tropical residential buildings into net-zero energy homes.
Shrijit was presented with the award by ASHRAE President, Dennis Knight, at an award ceremony at Loughborough University.
