CASE STUDIES:1 / BRINE LEAS HIGH SCHOOL Brief Process
Assessment criteria
While LSC gives guidance on the overall area for a new Post 16 Centre – 450m2 + 8m2 per learner, they do not provide a detailed breakdown of how the space is to be used. Accordingly, we initially discussed with the school an area analysis based on BB98, and the expected post 16 numbers. We analysed both the ‘standard’ version and the ‘technology / music bias’ version to give an indication of the likely room sizes and numbers that would be required to deliver the proposed curriculum. The total area for the new building is 2850m2 . A proposal was then put forward for the Brine Leas High School accommodation schedule.
Three options were designed and each option was appraised using the following criteria: • Suitability for, and ability to deliver the 16-18 curriculum
t: +44 (0)161 486 0429 f: +44 (0)161 486 0488
www.tace.co.uk
The Preferred Option • L-shaped three storey building, located to the front of the school site, providing a highly visible Post 16 Centre • The form of the building is oriented such that there is a hard edge to the North and West, reinforcing the aspiration that the existing North-South route between this and the existing buildings will one day become a covered external social space linking the two facilities.
• Visibility and presence on the school site • ‘Celebration’ of Post 16 education • Effect on wider community eg local residents • Adequacy of links to the existing school buildings • Effect on the school site • Delivery and emergency vehicle access • Parking • Pedestrian access / routes • Hard and soft play areas • Future flexibility • Within the new building • On the site with respect to potential BSF projects for the 11-16 curriculum • Environment & sustainability
• The building form also provides a ‘protected’ South facing social/ work space, which can be different in character to the school playgrounds for the 11-16 age group. • General site improvements including a new vehicular access route, parking and turning circle to the East, and a visual barrier between the play ground and parking to the West near the sports hall. This brings a significant benefit to the quality and safety of existing playgrounds. In addition, new hard play is provided to the south of the sports hall playground, to compensate for the play space lost by the new building’s footprint. • Internally, the building design consists generally of narrow plan teaching spaces which can be naturally lit and ventilated. Three light wells provide interest, light and a feeling of openness along the circulation routes. At ground floor, the main social/ dining space, a study area and the large vocational spaces have direct access to the external social/ work space.
• Safety and security • Cost & value • Risk

case studies:2 Saughall school Introduction Background A new Church of England primary school costing £5.452 million is to be built in the village of Saughall near Chester. It follows the approval of plans last year to amalgamate The Ridings Infant and The Thomas Wedge Church of England Junior Schools. Cheshire’s Executive put in place the finance for the scheme which also includes a contribution from the schools involved. Lead member for Children’s Services County Councilor David Rowland's said: “The amalgamation of the infant and junior schools is in line with our Transforming Learning Communities policy to create all through primary schools.” “Neither school is large enough to accommodate 280 pupils and extending either of the existing buildings is not considered a viable option." “Therefore the proposal is to build an all – through voluntary controlled primary school, providing ten classes on land in the grounds of the junior school." “Work will begin on site in July with the new school opening its doors to pupils in September 09.”

Typical Classroom Passive Ventilation
Ventilation
Air tightness
Windows are a cost effective, efficient and sustainable solution to fresh air and climate control in schools, when used properly.
With emphasises that the key to efficient passive ventilation is making the building fabric as airtight as possible. The Part L air tightness standard is set at only 10m3/hr per m2 of building fabric at 50 Pascal’s. Meaning this could be improved upon to save energy.
You don’t need expensive fans or stacks to ensure school children get enough fresh air. Well-designed windows perform equally well and for a fraction of the cost. First lesson after lunch; the classroom is warm and stuffy. It is an all-too-familiar scenario that designers of a new generation of schools are trying to avoid. Technical guidance has been redrafted and huge effort is being put into ventilation design to ensure that there is adequate fresh air and that classroom temperatures are neither too hot nor too cold. Looking at the existing stock of school buildings, in many classrooms, when the windows are closed, CO² concentrations routinely go above 2000ppm. The healthy maximum is 1000ppm, and CO² concentration should never go above 1500ppm.
Various pieces of legislation stipulate ventilation rates ranging from a continuous minimum of 3l/s per person to an occasional maximum 8l/s per person. To achieve these rates, designers are frequently incorporating fans into classroom designs. Stacks feature in some designs, taking advantage of buoyancy circulation to drive airflow. Each child in a classroom gives off heat equivalent to a 65W light bulb and each adult the equivalent of a 100W bulb. The columns of warm air rising from each pupil draw in fresh, cool air through the bottom of the windows, where it falls to the floor, while warm air laden with CO² is purged through the top of the windows. With a couple of exceptions, there are three windows per classroom. Thermal models of the schools were developed and possible trouble spots identified. There were rooms with higher occupancy, rooms that were deep plan, and rooms with only two, rather than three, windows. Computational fluid dynamics modeling was carried out to explore in more detail how these rooms would perform. With the aid of automatic actuators linked to CO² and temperature we will reduce CO² and improve the working condition.
www.tace.co.uk
Thermal models suggested that going from 10m3/ hr to 7.5m3/hr produced a 10% energy saving. And from 7.5m2 to 5m2 saved another 5%. The external cladding of the building isn’t always the way to improve the buildings overall air tightness for instance, better contact points where walls meet the roofs and proper sealing of drilled holes in the cladding, ensuring this you can lower the actual air tightness to around 6m3/hr which is 40% lower then the Part L specification of 10m3/hr. Improving the air tightness of the building also has its merits of improving the acoustics, as well as helping to maintain temperature stability.

Heating
To heat the school the decision was made to use Radiant Panels fed via a LPHW circuit operated via a Biomass Boiler. The advantages of using radiant panels are that there are no noise issues with them and also due to them being ceiling mounted they are very unobtrusive.
Sun Pipes can help to reduce this by eliminating the need to use electric lighting during daylight hours. At the same time the Sun Pipes offer considerable environmental and health benefits by creating better indoor working conditions. • Enables 4% daylight factor to be provided to suit deep plan classrooms. • No solar gain in summer months, or heat loss in winter as compared to conventional roof lights. • No maintenance inside or out. • Children and teachers work better under a natural light environment. At least 75% of electricity costs can be saved during the daytime, where Sun Pipes are used to replace the need for electric lighting during School hours.

Energy Analysis/Breeam
The Primary objective of Saughall is for it to be a Low Carbon Learning centre with the main goal of the scheme to become the first BREEAM excellent rated building in the United Kingdom. And with the pre-assessment of the building coming in at a score of 78% (Excellent) this looks extremely promising. With the use of the Biomass boiler alone this school will be saving a total of 12.5 tonnes of CO² a year.

case studies:3 St Anne’s Academy Introduction Background Academy Adulated..... TACE provide low carbon design solution latest scheme. St Anne’s Academy is part of the Building Schools for the Future programme, funded by sponsors from the Church of England and Rochdale BC. The academy will support 750 11-16 yr olds and 150 sixth form students. The £17.6m scheme will enhance the schools specialist facilities of technology, art and the built environment. Currently being developed by Willmott Dixon Construction the scheme is set to be complete in September 2010. WDC won the bid for the new academy with Aedas Architects. Once the basis of the design had been brought together it was felt a specialist services contractor should be appointed in order to progress the building services design, Rotary Group employed TACE to carry out the full mechanical and electrical design on a design and build basis.

The academy aims to meet the BREEAM rating of ‘very good’, provide 10% renewable’s (although not required) and cut C02 emissions by 25%. Preliminary calculations look positive, the buildings energy consumption has also been cut with additions to building structure, brie solei, orientation and high density, insulative fabrics which were brought to the table by the architect.
The building will utilise a biomass wood pellet boiler in order to provide heating and hot water to the academy, this boiler is supported with gas additions. High efficiency lighting and automatic presence detection and daylight dimming also enhance the energy efficiency of the classroom and office areas while meeting lighting requirements.
Whilst the design was being developed and after carrying out a dynamic simulation model some classrooms were found to be overheating when measured against the Building Bulletin 101 regulations. Undoubtley this was a hurdle to jump over, but with some careful coordination, and thoughtful design work from all parties, mechanical ventilation was incorporated into the classrooms which were found to be overheating. Clever controls will prevent fans from running in conditions which can be dealt with via the high level powered windows, only running when the temperature within the space exceeds 28degC.
St Anne’s Academy aims to be a benchmark for all future academy buildings, by reducing C02 emissions significantly, providing a safe and comfortable environment for all occupants and enhancing students learning by increasing the wealth and quality of educational and social facilities to the local community.
