Embodied carbon
The project incorporates several strategies that reduce material-related impacts and limit disturbance to the existing site.
Timber structure and prefabrication
The seven new lodges use prefabricated timber-frame construction. The wall panels were manufactured off-site with the structural frame, insulation, window openings and electrical wiring already integrated before being transported and assembled on site. This reduced construction waste, deliveries, noise and traffic during the six-month construction period.
The structural system uses C24 solid timber, OSB/3 bracing and GL24c glulam beams, with steel limited to the most highly stressed points. Mechanical connections using screws, anchors and steel angle brackets also support future disassembly.
Low-impact foundations
Instead of conventional excavated foundations, the lodges, walkways and terraces are supported on 160 self-drilling steel micropiles driven 4–5 metres into the ground without pre-drilling or soil removal. This avoids excavation and keeps the soil and existing root zones largely undisturbed.
Retention of existing trees
All trees on the site were surveyed before the buildings were positioned. The design placed the lodges between existing trunks, with some trees incorporated into the buildings through glazed patios. Underground utilities were also routed to avoid the roots. No trees were felled.
Material reuse and waste reduction
The interior flooring uses industrial oak parquet made from small offcut lamellas from parquet production, turning a manufacturing waste stream into a finished flooring product. The timber is sourced under FSC and PEFC certification.
Natural/untreated timber
The external larch slats are left untreated, avoiding additional chemical coatings and allowing the timber to weather naturally. Larch is also used for the decks and walkways.
Operational Emissions / Energy
The project has a strong set of documented operational energy measures.
Energy Class A4 / NZEB
The complex is certified Energy Class A4, described as the highest Italian class for nearly zero-energy buildings.
Thermal groundwater for heating
Low-temperature radiant floor heating is supplied by the resort's thermal groundwater, using the site's existing thermal resource as a renewable energy source.
Renewable coverage
According to the project information, 97 percentage of domestic hot-water and heating demand is covered by renewable sources.
Photovoltaic generation
A 19 kWp photovoltaic system is installed on the hotel roof to support the complex.
LED lighting
All lighting uses LED technology, with programmable indoor and outdoor lighting scenes.
Green roof
The flat roof areas include an extensive green roof that helps retain rainwater and reduce summer overheating.
Passive relationship with the landscape
The buildings retain mature trees and position the lodges among them. The project documentation specifically identifies the retained trees as providing shade to the lodges in summer.
Service and maintenance emissions
The project incorporates several choices that can reduce maintenance requirements and extend material life.
Untreated larch
The external larch cladding and decking are untreated. The timber is intended to weather naturally rather than requiring a chemical coating system.
Durable bathroom materials
Kaldewei steel-enamel shower surfaces and washbasins are made from steel and glass and are described in the project documentation as 100 percentage recyclable. The NEXSYS shower system is supplied pre-assembled, reducing installation complexity.
Kaldewei's published EPD documentation also states that its steel-enamel shower surfaces, bathtubs and washbasins can be separated and recycled at the end of their service life, without separating the steel from the enamel.
Durable/recyclable aluminium
The glazed façades/windows use Reynaers Aluminium systems. Aluminium can be recycled, and the manufacturer has Cradle to Cradle Certified Bronze coverage for a range of window, door and façade systems, including MasterLine 8.
Long-life material choices
The project uses mechanical timber connections, untreated timber, steel components and recyclable bathroom products rather than relying solely on permanently bonded construction. These choices support repair, replacement and eventual recovery of individual components.
Afterlife
The historic villa already present on the site was restored and converted into Green Villa Bertha, the largest suite in the complex. It includes a private spa with a sauna, steam bath, sensory shower, and heated outdoor Jacuzzi. This is a clear example of adaptive reuse, because an existing building was retained and given a new hospitality/wellness function rather than being replaced. For the new lodges, however, the documentation does not establish that the floor plans were specifically designed for conversion to unrelated future programmes.
The wall and floor elements are prefabricated and joined using screws, bolted anchors, and steel angle brackets, allowing components to be dismantled rather than demolished. The raised walkways and terraces use larch boards on timber slabs supported by steel T-beams, allowing the different layers to be separated. The steel micropiles were installed without excavation and can be extracted at the end of the building's life, leaving the soil largely as it was found. Untreated larch avoids chemical coatings that could complicate material recovery, while the steel-enamel sanitaryware and aluminium window frames are recyclable. The main limitation is the concrete floor slab containing the radiant heating, which is identified in the project documentation as the least separable component.
