16. • Thescrew pile was invented in 1833 by
Alexander Mitchell
• Thefirst use of screw piles was in 1838 for the
Maplin Sandslighthouse in the Thamesestuary
• Usedfor Portland breakwater in 1847 to create
world's largest man-made harbour
• From 1853 onwards, most of UK’spleasure piers
were constructed using screw piles.

Modern screwpiles
• Segmentedpile system
• Tocarry tensile, compressive, and lateralloads
• Constructed of helical plates welded to thick-walled
circular hollow-section steel
• Galvanisedasstandard
• Designlife of 120+ yearsis easilyachievable
• Provide for axial loads from 75 to500kN SWL.

19. Thethermal solution
Screwpile foundations asagroundheatexchanger
Thesun delivers 20 xmore heat per square metre per year than is used
heating a modern building, but at thewrong time. Socanthis be captured
economically?
Yes,but how do we store thisheat?
Our answer is – Underground Thermal EnergyStorage (UTES)…

Annualtemperature profile of the groundheat source
• Extract solar energy stored inthe
ground
• High temperature stability makesthe
ground agood heatsource
• 1 metre deep: 5-17°Cdepending on
the time ofyear
• >6 metres deep: 8-12°Cdepending
on the time ofyear
• Heat extraction rates vary with soil
type:
• Dry gravels / sand– poorconductor
• Wet soils / bedrock – good conductor.

21. Groundsourceheat pump
CO2savingsfrom heatpumps
• Ground source provides >25%reduction in CO2emissionswhen compared with gas
central heating
• Ground source heat should be afundamental part of energy-efficient construction,but
the high capital outlay required for the ground collectors hasresulted in aslow uptake
in the UKmarket
• Themarginal cost of adapting the foundations of abuilding (which are always
required), by utilising screw piles asground collectors aswell asfoundations, issmall.

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 keyto providing consistent energy-efficient air-tight buildings,
essential for the renewable technologies to achieve their expected levels ofperformance.

Innovative funding for integrated renewable solutions
Teamingup 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.
Weutilise district heating design and innovative
technologies such asUnderground Thermal
EnergyStorageusing the ThermoScrewPile™
system in conjunction with the latest solarPVand
PV/Tsystems,both roof- and ground-mounted.
Oncedesigned and costed, our partners ecoLOGIC
canarrange afunding package, providing for
CapEx-freeor heavily-discounted supply,
installation and maintenance of the renewable
technologies for 20+years – aTotExsolution.

25. ecoLOGICfunding
Thefuture of offsite housingandmixed-use developments
Thedistrict 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.
TheecoLOGICfunding mechanism not only
allows for zero carbon developments to be
cost-neutral when compared with less-
efficient more traditional forms of
construction, it canactually make it more
cost-effective.
This is because the ThermoScrewPile™
systemis paid for out of therenewables fund,
which means there is little or no foundation
cost to come out of the development fund.

• More than 500,000 geothermal heating systemshavebeen
installed in Swedenduring the last35 years. Project X
involves acomplete review of the concept (installation,
system and parts) in order to make the techniques and
technology more widely applicableworld-wide.
• Objective: more cost-effective GSHP(Ground SourceHeat
Pump) solutions involving boreholes
– Drilling, borehole heat exchangers, heat pump,installation
• Target environmental benefits for boreholedrilling:
– Practically silent
– 90%reduction in fuel consumption
– Environmentally friendly – only clean water, nodust
– Effective treatment of cuttings. 36
