Sustainable Building Design & Engineering Services
LEDA Engineering is a multidisciplinary consultancy committed to sustainable building design and engineering excellence. With over two decades of experience, we specialise in mechanical and electrical design, Passive House standards, and energy-efficient solutions for new builds and refurbishments. Our team combines architectural and engineering expertise to deliver holistic designs that prioritise environmental responsibility and occupant wellbeing. We employ advanced digital tools like BIM and the Passive House Planning Package (PHPP) to ensure precision and coordination across all project phases. Our lean design philosophy minimises resource use while maximising building performance, supported by post-occupancy evaluations to validate outcomes. As a certified Investors in the Environment (iiE) co-operative, we integrate sustainability into every aspect of our operations and client projects.Our collaborative approach ensures clients receive tailored advice from feasibility studies through to construction, with a focus on reducing carbon footprints and enhancing building functionality. We serve clients across Yorkshire and the UK, working on diverse projects ranging from community spaces to commercial developments. Our commitment to innovation is reflected in our adoption of renewable technologies and passive strategies, such as natural ventilation and daylight optimisation. Recognised for our expertise in sustainable transport and employee development, we strive to create a positive impact on communities and the environment through every project we undertake.

Questions
What is Passive House design?
Passive House is a rigorous energy efficiency standard ensuring comfortable, healthy buildings with minimal energy use. We apply PHPP modelling and thermal analysis to achieve this certification.
Do you work on listed buildings?
Yes, we have experience obtaining conservation approvals and implementing sustainable upgrades for historic structures while preserving architectural integrity.
How do you ensure building performance?
We use post-occupancy evaluations and soft landings approaches to verify systems function as designed, focusing on ventilation, heating, and energy efficiency.
What areas do you serve?
While based in Leeds, we work across Yorkshire and throughout the UK on diverse commercial, residential, and community projects.
Are you a co-operative business?
Yes, we operate as a worker-owned co-operative, promoting transparency, collaborative decision-making, and shared responsibility for sustainable outcomes.
How do you support sustainability beyond design?
We hold Investors in the Environment accreditation, implement office recycling programs, and encourage sustainable transport through bike facilities and e-bike access.
