BRE Environmental Assessment Method is the leading and most widely used environmental assessment method for buildings. It sets the standard for best practice in sustainable design and has become the de facto measure used to describe a building's environmental performance.

Our proposal for this landmark school knits together a community. The existing school currently suffers from behavioral problems and little interaction with its surroundings. This new building is planned to allow public uses at ground floor which include a public library, sports complex and theatre. More traditional educational spaces are on the upper levels. The internal planning allows both pupils and the community to benefit from these functions being in one facility. This building will demonstrate a new way a school can become a true civic building, offer exemplary sustainability credentials (BREEAM excellent and 60% carbon reduction) abd transformational teaching spaces.
§ St Paul’s Way Community School is an innovative educational building offering opportunities to develop new teaching methods in Tower Hamlets
§ St Paul’s Way Community School is a true Civic Building which offers much more to the community than a normal school including leading sustainable credentials
§ St Paul’s Way Community School’s striking architecture and unique internal spaces are designed and delivered within a very modest budget
r. A basic description of the building
The main organisational concept to both the building and the functionality of the school was to divide the 1200 pupil school into 5 smaller, more manageable units of approximately 250 pupils. Within each unit, or block, teaching spaces are clustered around a central atrium. The atrium space forms the heart of each block, housing a specific activity that informs and excites the surrounding teaching spaces.
The series of cluster blocks provide successive centres of excellence. The ground floor of the atriums house important school functions such as the Learning Resource Centre, dining and main hall as well as specific opening teaching spaces. These provide dynamic social and educational spaces within the heart of the school, allowing an exciting progression of learning and experience as one moves through the school.
Within the school one of the blocks is dedicated to science and will offer the latest thinking on science teaching taken from the governments research project called ‘Project Faraday’. This involves open lecturing spaces where several classes can come together to have demonstration experiments before splitting off into groups to test and perform them for themselves. Science studios are also provided to undertake virtual science experiments using computer software. The galleried design means that many of these central spaces can offer enormous potential in addressing the whole school community at once
s. The key innovative and low impact design features of the building
This building will first and foremost offer new and innovative spaces for teaching and learning. Each house includes 7-8 different teaching spaces offering the school a high degree of flexibility in how they teach. Large industrial sliding doors (reflecting Tower Hamlets large warehouse buildings of the past) allow spaces to be tuneable to different teaching styles and subjects
Supplementing this with the latest technology creates an exciting and innovative school. We are absolutely dedicated to ensuring the school building itself advances construction knowledge and techniques. This building will reduce the use of carbon in typical modern buildings by 60% using the buildings structural frame to naturally cool the spaces, heat recovery captures the heat generated from pupils, lighting and computers to reduce the need for excessive energy to warm the school. The section of the building is designed to generate passive air movement through attenuated vents to draw air from outside, through the classrooms and into the central spaces. This reduces the need for cooling which greatly reduces the overall energy use. The heating, when required, is provided from biomass boilers. The building also has the ability to connect to the neighbouring housing development CHP system once it is complete to further reduce the overall energy use. The renewable energy provided by this building is 25% (which exceeds the government’s targets) and overall this will have a BREEAM rating of Excellent
In addition we have developed this design wholly in 3 dimensions. Computer models were used from the start of the design and these models formed part of the stakeholder presentations through to the daylight testing using sophisticated CAD software
t. The steps taken during the construction process to reduce environmental impacts, i.e. innovative construction management techniques.
• Damping down surfaces to prevent unnecessary dusk.
• Handheld tools have been used with dusk suppression/dusk collection devices.
• Recycling rainwater during construction for damping down surfaces to reduce dusk.
• Installation of water cistern hippos to reduce water used when flushing toilets within the site office.
• Employing the use of mains water pressured toilets within welfare facilities to reduce volume of water used when flushing toilets.
• Use of concrete skips recycling station to wash out concrete skips, segregate sediment, and recycle water.
• Installation of solenoid valve to mains water supply to reduce water usage.
• Installation of separate water meters to site and welfare facilities to monitor water usage.
• Istallation of separate electrical meters to site and welfare facilities to monitor electric usage.
• Istallation of temporary builders works sub-station to reduce the need for generators.
• As much timber as possible has been sourced from a sustainable source (FSC).
• Only recycled paper has been used within the site office facilities.
• Recycling of site office waste.
• Recycling of gypsum products, timber, metals, and plastics.
• Labelling of all electric switches within offices and welfare facilities reminding all personal to switch lights off when leaving a room.
• Separate COSHH storage to ensure hazards are contained and managed correctly.
• Responsible removal of hazardous products.
• Use of low VOC paints in most applications.
• Employment of a fully licensed waste carrier.
• Double bunding of fuel storage areas and generators.
• Use of spill kits if required.

Local setting and community context
The St Paul’s Way Community School sits within a Masterplan for the redevelopment of the whole of the street. This project is the catalyst for this redevelopment and as such sets the quality for the future. The siting of the school widens the public pavement in front of the school up to 10 metres in width to allow clear and easy passage of pupils as well as increasing the impact and setting of this new public building. The quality of the Architectural response to this site is critical in raising the quality, ambience and community interaction along St Paul’s Way. The south east corner of the site addresses a red brick church on the opposite corner. We have created a new public square here, again to enphasise the civic nature of the school, as well as to improve the setting for the church. We are currently in discussion with the council and will be raising the road surface to create a shared surface to give the feel of a large public landscape that joins these two significant public buildings together.
In addition, we have throughout the projects design consulted with the pupils, staff and community to ensure this building meets the needs of all members of the community.
Whole Life Costing
Throughout the design of this project a whole life cost model was used to ensure decisions were economically sustainable throughout its life. This model was instrumental in helping us choose the right materials for their purpose.
