St Luke’s, a pioneering two-form entry primary school, was designed to achieve BREEAM ‘Excellent’, and was the first primary school in the UK to secure this rating. Through extensive user consultation and developing an understanding of the user's requirements, we developed a plan based around two shared hubs that support and enhance the school’s approach to creative shared teaching.
A key architectural generator for the project was to provide a building that was highly energy efficient: to have minimal heating loads, minimal requirement for artificial lighting whilst maintaining a comfortable working environment that is an inspiration and an educational tool for all. Careful attention has been given to the shape, form and section of the building, to maximise daylight, control solar gain and enable natural ventilation to all main spaces. The construction is an all timber structure, insulated with 300–400mm thick recycled newspaper insulation in a ‘breathing construction’. Externally the building is clad with UK grown Douglas Fir, and the roof is finished with cedar shingles. The building is heated with a biomass boiler linked to underfloor heating. A BMS controls ventilation and passive night-time cooling.

A conceptual generator of 'contrast' was adopted early in the project to guide design, following lengthy research into past and current teaching methodologies. A child's perception of the nature of 'things' from an early age, is fundamentally a view of 'extremes': things and experiences are seen as 'black or white'. A child has little notion of 'grey' or degrees of difference. It is in fact the 'degrees of difference' that a primary teacher is empowering the child to discover through experience, play and learning. A child's uniform notions of the world are 'ordered' and formal in their polar simplicity, whereas adult notions are informed from a wider experiential and historic context, resulting in an increasingly 'blurred' degree of categorisation with greater fluidity: chaotic.
A child's set of contrasts would include: good/bad; black/white; right/wrong; soft/hard; rough/smooth; light/dark; warm/cold; in/out and so on. The architectural challenge was to respond to the notion of contrasts to create a building that stimulates the natural curiosity of each child and gives teachers a dynamic teaching environment.
Maintaining visual links with the surrounding environment helps blur the perceived internal, external boundaries and locate oneself within the building. A language of transparency was sought to express the visual links from side to side and front to back and throughout the building with particular attention to the visual links with the green spaces immediately adjacent.
Architype started work on the project in the summer of 2006 following several days consultation in the school. Architype met with all the staff (including teachers, lunch time supervisors, cleaners and specialist staff, such as, the home school link officer and some of the children) to develop a greater understanding of how St Luke’s CE Primary operates and feels, how the ethos of the school is expressed throughout the school and the aspects of St Luke’s CE Primary which are unique and special. A key aspect of Architype’s approach is to discover, through consultation, the character and personality of an organisation and to then explore through a conceptual design approach ways of expressing this.
Of course the children forwarded the most creative and innovative ideas, featuring an 'in-school chocolate factory', and a 'ghost-train roller-coaster connecting the classrooms'.
Learning from Post-Occupancy Evaluation
St Luke’s is an example of a well-executed primary school that has had good performance outcomes and offers valuable learning for the delivery team. The occupants are pleased with the environmental conditions and overall they have a very high level of satisfaction with the building. The electric usage is higher than hoped, which is typical of new-build primary schools. The users have been very engaged in the energy management, which has assisted them in taking ownership of the building and driving down energy use.
There were problems aligning the meter readings taken from the BMS and the mains readings, as the electric and biomass readings were significantly different between the two datasets. The heating was operating during the holiday weeks, causing heat energy spikes, when the school was empty. The heat energy use ranks in the best 25% of primary schools, and better than CIBSE best practice.
The classroom daylight and electric lighting strategies were effective, successfully enabling the children to work with minimal – if any – artificial light. Using three-four lighting zones gave each classroom the flexibility to have on only the lights they needed, and teachers and pupils were mentored through our soft landings approach to learn to habitually switch lights off. The classrooms oriented north/south worked best, as the whiteboard is in the darkest natural lighting zone.
Architype’s approach is to integrate sustainability from first principles, rather than add it later. We describe this as ‘Eco-minimalism’. The plan and the section of St. Luke’s are carefully integrated together to moderate the environment efficiently to reduce energy consumption, achieve good daylighting, control solar gain and achieve natural ventilation in every room. It was the first primary school in Britain to achieve an ‘Excellent’ BREEAM rating.
