INTRODUCTION This report demonstrates how the sustainability and energy strategy for the proposed Kettering Buccleuch Academy meets the objectives of Planning Policy 14: Energy Efficiency and Sustainable Construction and the Sustainable Design Supplementary Planning Document. SUSTAINABLE APPROACH Willmott Dixon has identified the following sustainability targets for Kettering Buccleuch Academy:

Achieve a BREEAM Very Good rating.

Meet the requirements of Building Regulations 2006

Achieve the Partnership for Schools requirement of a 60% reduction in carbon emissions Willmott Dixon’s approach to sustainable design is to deliver facilities that maximise positive educational outcomes and create positive and inspiring learning environments, which help raise aspirations and attainment. Our design proposals are based on the good design practice hierarchy:

Passive Design Measures The passive design features of the proposed design for Kettering Buccleuch Academy include:

Solar-control glazing (low g value or solar transmission value amounting to <0.45 while maintaining good light transmission through the glazing LT = >60%)

The windows proportions and configurations maximise daylight penetration into the space, and provide a light and airy environment without the need for excessive artificial lighting.

Exposed concrete soffits provide thermal mass to passively temper the internal environment, reducing peak temperatures in the space.

Temperature and CO2 detectors help building occupants to maximize control of natural ventilation inlets

Teaching spaces are naturally ventilated, with mechanical assistance used when necessary.

High levels of thermal insulation and enhanced fabric reduce heat loss and heat gain

Improved U-values



of 25

Active energy efficiency Active energy efficiency measures include:

energy-efficient lighting throughout, with intelligent daylight dimming and presence detection

local heating and ventilation control

variable speed pumping with two port zone control, enabling zoned heating control for different occupancy times

variable-speed fan control

direct sub-metering of substantial energy uses

free cooling – where physical mechanical cooling is required, free cooling is still provided by using adiabatic cooling air handing units rather than conventional refrigeration equipment. Adiabatic cooling uses the cooling effect of water spray introduced into the air stream.

metering – all substantial energy uses are sub-metered and linked to the BEMS. In addition, metering data is provided to the virtual learning platform via interface software, and data is provided to CCC’s central monitoring.

Low and zero-carbon technology A major aspect of sustainable design is strategic fuel saving and maximising energy efficiency. The building and engineering systems ensure energy and carbon emissions are minimised. Low and zero carbon (LZC) technologies have been considered in detail. A LZC appraisal has been carried out for the plant to establish the best technology for the site. The following section discusses the LZC technologies available, and those that are suitable for the building. The LZC technologies that have been assessed are:

Biomass boilers

Bio-oil boilers

Community heating and combined heat and power (CHP)

Solar thermal collectors

Wind turbines

Photovoltaics

Ground-source heat pumps Bio-mass and bio-oil boilers have been considered, and are not the preferred solution for the client due to the requirements for fuel deliveries and ensuring a reliable guaranteed source. Community heating and CHP are not viable due to the lack of a continuous annual heating demand. Wind turbines were dismissed on planning grounds as the hub height would need to be significantly above the buildings to achieve the required yields. GSHPs were dismissed on the grounds of excessive capital costs exceeding those within the budget. The conclusion of the LZC study showed that the optimum solutions for incorporating renewable energy into the scheme would be to install a combination of photovoltaic panels and solar hot water collectors.



of 25

A solar hot water system uses solar collectors to trap the thermal energy from the sun and heat water. The most common application of solar collectors for providing domestic hot water.

The most efficient type of solar collector is the evacuated tube. It uses a heat pipe to collect solar energy and transfer it to water, which is then pumped to a buffer vessel where it pre-heats domestic hot water for use in the building. Solar thermal collectors are a good solution for reducing carbon emissions but can only provide a limited reduction in overall carbon due to the relatively low hot water demand within the building. It is proposed that 25m² of solar collectors shall be provided (in total) to supplement the domestic hot water load. These will be located at roof level on the new building below the level of the parapet and also located on the retained existing buildings at roof level.

Photovoltaic (PV) arrays capture energy from the sun and convert it into electricity.



of 25

Solid PV cells are commonly mounted in arrays either on roofs or walls. Each array must be configured so that air can circulate behind to dissipate the heat generated in the system. Any PV array would need to be carefully positioned so that it did not fall into shadows. The best option would be to position the array on the roof of the building, as it would be the only suitable location that would not be shaded. This position is also easily accessible for maintenance and suitable as an educational tool. The PV array for Buccleuch Academy would be between 75 and 150m² depending on final configuration to compliment the solar thermal technology in delivering carbon free energy to the academy. These measures have enabled the design to achieve the Partnership for Schools requirement of a 60% reduction in carbon emissions, exceed the requirements of Building Regulations and achieve a BREEAM Very Good rating. OTHER SUSTAINABLE FEATURES Sustainability is ‘designed-in’ from the onset by using the energy conservation BEMS scheme. The sustainability benefits this scheme brings are: • Daylight control of lights with automatic dimming using light-level monitoring • Temperature and CO2 detectors help building occupants to maximize control of natural ventilation inlets. • Demand-led heating and cooling strategies to ensure the heating or cooling plant is only used as needed by the school building, including free cooling for night purging. Adiabatic cooling The AHUs serving the drama, theatre and primary halls are designed to use adiabatic free cooling that uses the latent heat of evaporation to cool the supply air without the need for artificial cooling or chillers. Night purge Free cooling at night time will be used when heat loads in the buildings are high overnight. This will be achieved by running fresh air plant (with no heating or cooling) when the outside air temperature is low enough to naturally cool the internal spaces. Alternatively passive ventilation openings can be used to lower heat loads in the building at night, without the need for mechanical systems, when conditions allow. Optimum stop / start algorithms The optimum stop / start algorithm ensures the building is at the correct temperature during occupancy and appropriate comfort levels are met. The same algorithm can also be used to switch off plant early, such as under-floor heating and radiator circuits, to save energy. BREEAM This section of the report details Willmott Dixon’s envisaged means of compliance to achieve a rating of

Very Good under BREEAM Education 2008 for Buccleuch Academy.

The BREEAM Environmental & Sustainability Standard provides an authoritative means of minimising the

adverse effects of buildings on the global and local environments whilst promoting healthy and

comfortable indoor environments.



of 25

The BREEAM rating is based on the number of environmental credits achieved under each category

multiplied by a weighting factor. The weighting factors are applied in order to account for the relative

significance that each category has on the environmental impact of the building. The main categories

that are assessed are as follows:

Management

Health & Wellbeing

Energy

Transport

Water

Materials

Waste

Land Use & Ecology

Pollution

The BREEAM rating is given as Pass, Good, Very Good, Excellent, and Outstanding based on the

environmental and sustainability credentials of the development.

Credit compliance is demonstrated by the submission of evidence by the Design Team for review by the

licensed BREEAM Assessor, to be carried out as the design develops.

Final certification is subject to a Quality Assurance check by the BRE at both design and post

construction stage.
