District Scale Decarbonisation

Specialists in Renewable Heat

The key to scaling up heat decarbonisation is to move from building-level to neighbourhood-scale solutions that are more efficient, more inclusive and more impactful.

Practically, this means working with local authorities and community representatives to define the geographical scope for a project and appraise every available option for neighbourhood heating.

The most efficient, low-carbon systems are those which maximise recovery of waste heat by associating large numbers of homes requiring heating with buildings requiring cooling such as supermarkets, offices and data centres.

Ground Source Engineering has the vision, initiative, experience with policy/legislation and technical expertise to drive forward the development and roll out of this approach for the UK.

Energy modelling

Energy demand calculations

Ground Source Engineering selects from industry standard energy assessment methodologies to provide the most appropriate load assessment for every project:

  • MCS heat loss calculations and dynamic simulation modelling (DSM) to accurately predict building energy demand.
  • SBEM and SAP reports for compliance with the energy efficiency requirements of the building regulations as set out in Part L of Schedule 1 to the Building Regulations.

Our process ensures optimised performance for your project. Estimated loads based on SBEM/SAP output or rules of thumb lead to over designed or under designed systems. In order to design a ground source system correctly, an accurate load assessment is required.

Ground Source Engineering can prepare your heat loss calculations either as a standalone load assessment or as part of a system design.

GSHP Engineering

Ground source heat pump system detailed design, RIBA stages 3 and 4

GSHP system detailed design (RIBA stages 3 and 4) in accordance with all relevant regulations and codes of practice.

Utilising closed and open loop design philosophies, applications include: tower blocks, housing developments, leisure centres, fire stations, social housing projects, schools, research facilities and car parks.

Well designed systems will reflect favourably in SAP, helping the scheme comply with the energy efficiency requirements of Part L.

Caspar brings to Ground Source Engineering four years' experience as lead engineer on Kensa's ground breaking projects. He led the design for pioneering projects involving large scale ground source heat pump systems across the UK for new and existing buildings.

Ground Source Engineering can provide ground source only, or hybrid systems, capable of space heating, hot water, and space cooling. Integration with solar thermal and/or solar PV often provides the highest-performing solution.

Caspar Sayany MEng AMEI AMIMechE

Director and Principal Engineer

Prior to founding Ground Source Engineering, Caspar worked as a ground source system engineer at Kensa – the largest ground source design-and-build contractor in the UK and the only UK manufacturer of ground source heat pumps.

During this time, Caspar led designs for a range of large and complex ground source projects for high profile clients including councils, housing associations, and an open loop mine-water heat energy and storage project for the British Geological Survey at the Glasgow Observatory. Caspar also designed the UK’s first ever split-ownership ground source project, Heat the Streets. Prior to this, Caspar worked at Regen, a leading strategist on the pathway to net zero.

Caspar is currently the technical lead at Ground Source Engineering. For more information, including a notable list of award winning projects, please visit Caspar's page on LinkedIn.
