Basic Description of the Project
The development comprises the construction of a new bespoke technical facility for Surrey
Satellite Technology Ltd, built in collaboration with the University of Surrey. The development is
situated within the Surrey Research Park, Guildford, Surrey.
Basic Description of the Building
The New Technical Facility known as The Kepler Building is located on Stevenson Place and is a 3
storey steel portal frame building, clad with lightweight metallic materials. The roof is metal
standing seam and the rear and mid sections of the facades clad in silver coloured horizontal
insulated panels. The front section is predominantly glazing and expressed vertical blue glass fins.
Black ceramic tiles with white star flecks, stack bonded to give a modulated cladding
appearance reinforce the corner giving strong contrast to the glazed entrance lobby.
The building comprises working areas which encompass engineering, assembly, integration,
testing and clean rooms to the ground and 1st floors. Plant areas and mezzanine storage are
provided at second floor level.
Core partitions and lift enclosures are constructed in block work; the remainder of the partitions
are constructed of plasterboard and metal stud construction. The building is provided with two
staircases located at opposite ends of building.
The building is set within soft and hard landscaping with the provision of car parking and service
areas.

BREEAM Rating & Score
The New Technical facility is to aiming to achieve a ‘Very Good’ certification for BREEAM under
the ‘Other Buildings’ scheme.
An assessment of the likely performance against the credit criteria has indicated that it is possible
to achieve a ‘Very Good’ BREEAM rating.
The University has made a commitment to achieving this rating through careful and innovative
design. The design team are currently finalising the required elements and compiling the
necessary evidence to complete the BREEAM assessment.
Key innovative and low-impact design features of the building
Building Fabric: Lower ‘U’ values than those required for part L of the building regulations are
being targeted.
Air Tightness: A lower air permeability rate than required for part L of the Building Regulations is
being targeted.
Building Management System: A BMS will be used to monitor the energy usage within the facility.
This will allow local control and optimum energy usage.
Lighting & Lighting Control: High frequency Luminaires are to be utilised to reduce power
consumption. This is combined with natural day light where possible to reduce the need for
lighting use.
Heating & Cooling: Fan coil units in areas of intermittent occupancy (such as meeting rooms) are
interlocked with presence detectors to set the FCU’s into a set back mode, reducing fan speeds
and increasing the temperature dead-bands to reduce energy consumption
Heating and cooling water systems operate with variable speed pump sets and 2-port valves with
pressure sensors reducing the pump speed to suit the building load only.
Heat Recovery: Significant filtered return air recirculation is being utilised; this is direct heat
recovery and saves energy. Heat is also recovered from the exhaust air.
Solar Shading: Solar shading is provided by way of horizontal brise soleil to the south elevation and
vertical tinted glass fins to the east elevation, which reduces the potential solar gain
Landscaping & Earthworks: Cut & Fill approach adopted to reduce the usage of imported
materials. Incorporation of reinforced soil slopes which reduce the amount of fill required and
allow the use of locally available soils.

Reduce environmental impacts, i.e. innovative construction management techniques
Protection of existing ancient woodland bounding the site, buy provision of tree root protection
measures.
Re-use and recycling of construction waste. All site waste is segregated into waste streams to
ensure it can be re-cycled efficiently upon removal from site.
During the construction process dust suppression techniques have been employed to minimise air
pollution.
Measures have been introduced to facilitate the Legacy use of the building. Provision has been
made in the design of the structure to facilitate the introduction of infill floors which will minimise
the enabling works required for the legacy use of the building.
Social or economical sustainable measures achieved:
Natural ventilation by way of openable windows has been provided to specific areas for both the
current use and legacy use. The use of natural ventilation negates the energy consumption
associated with mechanical ventilation.
A sustainable drainage system has been adopted on the project which comprises the provision of
large areas of permeable paving and associated attenuation tank. The tank is fitted with a
Hydrobrake which restricts the discharge of water into the existing below ground surface water
system. This rate mimics a similar discharge to that of a green field site.
