Advisory & project management — EneX geothermal system
Foundation and energy management — solved ecologically and efficiently.
One integrated system combines foundation piles with innovative heat exchangers: buildings are heated and cooled from their own foundation, independently of oil. We advise building owners, investors and planners — from system design to commissioning.
The system in detail
Carport UNI: the complete system at a glance.
Tailor-made for investor and site, delivered as a complete service from design through production to installation — demountable, extendable and CE-certified for the EU.
Modular design
One module, three variants.
The typical carport module is 5.5 m wide and carries a roof area of around 5.5 × 5 m — depending on panel size. It adapts easily to wider or atypical parking spaces; installed in a row, the structure accepts up to 8° of longitudinal slope.
- UNI South — mono-pitch roof facing south
- UNI North — mono-pitch roof facing north
- UNI Double — covers two rows of parking spaces
- Columns in steel or timber
Scope of delivery
Complete service: from design to installation.
Project preparation comes entirely from one source — from the model study through the complete structural assessment to the implementation documentation for your specific project. Delivered either as a partial service or as a turnkey project.
- Design and production of the carports
- Design, manufacture and installation of the foundation structure
- Aluminium mounting system for the PV panels
- On-site installation and transport of all components
Foundation
Screw foundations: grounded without concrete.
Ecological foundations without concrete: the screw foundations minimise intervention in the soil profile and the cost of site preparation. Adjustable screws made from thick-walled tube (series 89 × 5 mm) provide stability and a long service life.
- Immediately load-bearing — no curing times
- DTH pre-drilling: installation on concrete, asphalt and rocky subsoil
- Screw lengths 1,550 / 2,050 mm, extensions up to 2,000 mm
- Adjustable for precise alignment of the structure
Structure
Thin-walled steel: light, precise, durable.
The load-bearing structure is made of thin-walled steel profiles, developed in cooperation with voestalpine Profilform and produced on automated profiling lines. Compared with rolled profiles this saves around 60% weight and 30% cost — with high dimensional accuracy and fast assembly thanks to precisely marked parts.
- Statics designed for wind and snow loads across 80% of Europe
- Z350 zinc coating, thick-walled elements hot-dip galvanised
- Design to EN 1990/1991/1993, production to EN 1090
- CE certification of all components and the overall product
Panel mounting
Aluminium slide-in system for any framed panel.
The PV panels are set vertically by their long edge into the groove of aluminium slide-in profiles, with sealed panel joints — three panels stacked as standard, recommended panel size approx. 1,100 × 1,700 mm.
- Any framed PV panel can be used
- Fast module replacement, easy maintenance
- Galvanic corrosion eliminated by design
- Certified to EN 1090-3
Drainage & extras
Planned down to the detail — rainwater included.
A complete drainage system carries rainwater from the panel roof via gutters and downpipes into the sewer — made of hot-dip galvanised steel sheet or titanium zinc (0.55–0.7 mm) and designed individually for site, carport type and sewer capacity.
- Geological survey: tensile tests, geoscan, chemical soil analysis
- Charging stations, battery storage and lighting
- Geodetic surveying and site equipment
- Fire-protection documentation
- 2/3 of the heating energy from the ground, independently of oil
- 40 m+ pile depth sMartex rotary displacement pile
- 100 % leak tested every probe, with an acceptance certificate
- 5 components one system, designed to work together
We are convinced that economics and ecology can already be combined to good effect today, and we prove it in every project we support with the EneX geothermal system. This is our contribution to a sustainable future, independent of fossil fuels.
The complete system
Build the foundation for energy with us.
You need to found your building. You need a solution for your energy management. Both can be solved in a single structural element: the EneX geothermal system uses hollow foundation piles to harvest near-surface geothermal heat.
- Low-cost energy. Geothermal energy is freely available and, apart from the installation, free of charge. We optimise your energy efficiency and you cut your costs.
- Environmentally sound. You draw two thirds of your heating energy from the ground, independently of oil, and complete the system with a heat pump.
- High operational reliability. Built-in bleed valves rule out unwanted air pockets. Every pile can be regulated individually.
- Verified quality. A 100 % leak test of the geothermal probe with an acceptance certificate guarantees a high quality standard.
Components
More than the sum of its parts.
Drawing on experience from industry, research and engineering, we ensure the system is designed to its optimum. Every component is carefully chosen.
- 01
Pilotherm® hollow pile
A hollow pile made of spun concrete. The continuous cavity allows heat to be extracted and stored along the entire length.
- 02
sMartex rotary displacement pile
The alternative wherever piles cannot be driven — quiet and free of vibration.
- 03
Geothermal probe
Flow-optimised internal geometry: lower pressure loss, higher circulation-pump efficiency, shorter payback period.
- 04
Heat pump
Controls underfloor or radiator heating systems based on the mean outdoor temperature. Passive and active cooling included.
- 05
Solar photovoltaics
Combining the system with solar energy means operation is covered entirely from renewable sources.
