About Us
Renjith Jayapalan Nair
I wear many hats: engineer, consultant, and passionate advocate for sustainable building practices. At DesignBuilder Software Ltd, I blend technical expertise with creativity to develop cutting-edge solutions that push the boundaries of building performance.
But my journey doesn't end there. I'm deeply involved in professional organizations like IBPSA England, where I serve as a board member and newsletter editor. Here, I connect with fellow experts, sharing insights and staying ahead of industry trends. As the communications chair at ASHRAE UK Chapter, I drive discussions on sustainable building design and energy efficiency, shaping the conversation around crucial topics. Additionally, as the social media secretary at CBISE Building Simulation Group, I'm dedicated to spreading awareness about groundbreaking research and emerging trends in the field.
