Green transition · WarehouseLife cycle
Steel across the building's life cycle
A green building is judged across every stage, from siting to the day it is taken down, not just its years in use.
- SitingA light steel building gets by with a smaller foundation, an advantage on weak soils and tight plots.
- DesignStructural design is done alongside fabrication; sections are optimised and no steel is wasted.
- ConstructionParts are prepared in the shop and bolted on site: a short, dry, quiet build.
- OperationA solar-ready roof and a frame for an insulated envelope cut energy use.
- MaintenanceRepainting and joint checks on a visible, accessible frame.
- Renovation & dismantlingBolts come out; the frame is re-erected elsewhere or goes back into steelmaking as scrap.
Why steel is green
Four reasons
It recycles
Steel can be melted down and made again without losing its properties. A building at the end of its life is raw material, not waste.
It is lighter
A lighter frame needs a smaller foundation, so less concrete and cement are used.
Dry site
Parts are prepared in the shop and bolted together on site, with far less formwork, water and rubble.
It can be rebuilt
Bolted joints come apart, so the frame can be reused in another building somewhere else.
The Turkish framework
The rules shaping green buildings
Regulations now require energy performance and renewables from new buildings, and carbon has become a cost line in exports.
nZEB
Nearly zero-energy buildings
Since 1 January 2025, new buildings of 2,000 m² or more need at least a class B energy certificate and at least 10% of their annual energy from renewables to get a building permit.
EPC
Energy performance certificate
Buildings are rated A to G. New buildings need at least class C for energy and greenhouse gases to get an occupancy permit.
YeS-TR
Turkish green building certificate
The national scheme set up by the Green Certificate Regulation for Buildings and Settlements, being rolled out in stages starting with public buildings.
CBAM
EU Carbon Border Adjustment Mechanism
Entered its definitive phase on 1 January 2026: embedded emissions in iron and steel sold into the EU now carry a cost, so low-emission steel gains value.

Comparison
Concrete and steel, through a green lens
General tendencies; every project's result depends on its own calculation.
| Topic | Reinforced concrete | Steel frame |
|---|---|---|
| Building weight | Heavy | Lighter |
| Foundation and concrete | More | Less |
| Water and formwork on site | Heavy use | Little; dry assembly |
| Build time | Longer; curing time | Shorter; prepared in the shop |
| Later changes | Hard; needs demolition | Easier; bolted joints |
| After demolition | Rubble | Recycled or reused material |
Applications
What we do for the green transition
Steel buildings for urban renewal
A lighter, earthquake-resistant steel frame that rises quickly in place of the demolished building.
Residential · ApartmentsRooftop solar supports
Solar panel supports for warehouse, workshop and factory roofs, with the roof designed for the panel load. A direct contribution to the nZEB renewable requirement.
Solar · Warehouse · WorkshopDemountable structures
Bolted systems for temporary warehouses, site buildings and exhibition structures that can be taken down and re-erected elsewhere.
Bolted connectionsFraming for an efficient envelope
Wall girts and roof purlins to carry sandwich panels and insulated facades, the route to a better energy class.
Facade · RoofGreen roof structure
Beams and decks designed for the soil and water load of a planted roof.
Roof · Load designSupports for rainwater and services
Steel platforms and hangers for rainwater tanks, gutters and service runs.
Water efficiencySample application
