• The screw pile was invented in 1833 by Alexander Mitchell

• The first use of screw piles was in 1838 for the Maplin Sands lighthouse in the Thames estuary

• Used for Portland breakwater in 1847 to create world's largest man-made harbour

• From 1853 onwards, most of UK’s pleasure piers were constructed using screw piles.

Screw pilesModern screw piles

• Segmented pile system• To carry tensile, compressive, and lateral loads• Constructed of helical plates welded to thick-walled

circular hollow-section steel • Galvanised as standard• Design life of 120+ years is easily achievable• Provide for axial loads from 75 to 500kN SWL.

The thermal solutionScrew pile foundations as a ground heat exchanger

The sun delivers 20 x more heat per square metre per year than is used heating a modern building, but at the wrong time. So can this be captured economically?Yes, but how do we store this heat?

Our answer is – Underground Thermal Energy Storage (UTES)…

Ground energy as a heat sourceAnnual temperature profile of the ground heat source

• Extract solar energy stored in the ground

• High temperature stability makes the ground a good heat source

• 1 metre deep: 5-17°C depending on the time of year

• > 6 metres deep: 8-12°C depending on the time of year

• Heat extraction rates vary with soil type:

• Dry gravels / sand – poor conductor• Wet soils / bedrock – good conductor.

Ground source heat pumpCO2 savings from heat pumps

• Ground source provides > 25% reduction in CO2 emissions when compared with gas central heating

• Ground source heat should be a fundamental part of energy-efficient construction, but the high capital outlay required for the ground collectors has resulted in a slow uptake in the UK market

• The marginal cost of adapting the foundations of a building (which are always required), by utilising screw piles as ground collectors as well as foundations, is small.

Turnkey deliveryIntegration by partnering with experts in their field

Design partners• Architectural• BIM• Energy • Structural

An integrated approach unlocks our ability to maximise the efficiencies of the ‘build system’ and the performance of the renewable technologies within. Apart from speed of delivery, offsite manufacture is the key to providing consistent energy-efficient air-tight buildings, essential for the renewable technologies to achieve their expected levels of performance.

ecoLOGIC fundingInnovative funding for integrated renewable solutions

Teaming up with leaders in the renewable energy sector and with manufacturers of energy-efficient, offsite-constructed build systems provides truly zero carbon solutions for large-scale developments.

We utilise district heating design and innovative technologies such as Underground Thermal Energy Storage using the Thermo Screw Pile™ system in conjunction with the latest solar PV and PV/T systems, both roof- and ground-mounted.

Once designed and costed, our partners ecoLOGIC can arrange a funding package, providing for CapEx-free or heavily-discounted supply, installation and maintenance of the renewable technologies for 20+ years – a TotEx solution. 24

ecoLOGIC fundingThe future of offsite housing and mixed-use developments

The district heating concept is especially appropriate for using renewable energy in mixed-use developments. Surplus heat and electrical power generated by one type of building can be redistributed to others with different demands and timings, offering substantial efficiency gains. The ecoLOGIC funding mechanism not only allows for zero carbon developments to be cost-neutral when compared with less-efficient more traditional forms of construction, it can actually make it more cost-effective.This is because the Thermo Screw Pile™ system is paid for out of the renewables fund, which means there is little or no foundation cost to come out of the development fund.

• More than 500,000 geothermal heating systems have been installed in Sweden during the last 35 years. Project X involves a complete review of the concept (installation, system and parts) in order to make the techniques and technology more widely applicable world-wide.

• Objective: more cost-effective GSHP (Ground Source Heat Pump) solutions involving boreholes– Drilling, borehole heat exchangers, heat pump, installation

• Target environmental benefits for borehole drilling:– Practically silent– 90% reduction in fuel consumption– Environmentally friendly – only clean water, no dust– Effective treatment of cuttings.



• Fuel poverty

• Utility obligations

• Government funding

• Life-cycle cost savings

• Lifestyle living.
