Our services span the entire design and construction development process, through four key stages: Define, Design, Realise, and Learn. From initial planning through to post-occupancy, we provide comprehensive support and expertise at every step.
Define
At Delta Q, we focus on fully understanding our clients’ goals and project needs. We offer expert guidance on setting achievable environmental targets, including operational energy, whole life carbon, and net-zero strategies. Our in-depth environmental design analysis provides a strong foundation for actionable recommendations that drive sustainable, high-performance outcomes

Design
Collaboration is key to our approach. We work closely with design teams to create high-performance, low-carbon buildings, balancing cost effectiveness and buildability with thermal performance and carbon reduction. We remain focused on the needs of end users and occupants, ensuring our low-energy solutions are practical, durable, and easy to maintain.

Realise
During construction, we engage with the supply chain, leveraging their expertise in processes and products. We foster cross-trade collaboration and provide training on sustainable building practices. This approach not only instils pride in a job well done but also ensures we meet our project goals, whether it’s Passivhaus or a net zero carbon building.

Learn
On completion, we support contractors and clients in ensuring the building functions as intended. We assist users in understanding how to operate the building and evaluate its performance against design metrics. Through this process, we gather insights from occupant experiences and building data, which we apply to future projects.
At Delta Q, we are also committed to sharing our knowledge. Our founding director, Piers Sadler, is a trainer on Passivhaus Designer and Tradesperson courses. We also offer bespoke training for contractors and CPDs for architects, designers, and engineers.
