Description

Squeezed in between 4-15 storey residential buildings, which in recent years years have been built in concrete and brick at Hvidovre Station, a completely different building has appeared in a few days. Grønnebro housing project, which JCN Bolig is building for the union-owned AKF Holding A/S, the residents' future community house differs significantly from the rest of the construction. "When we were going to make a community house here in a building called Green-Bridge, we wanted to make a building that actually celebrates the green transition," Karen Andersen, head of sustainability at JCN Bolig, tells BuildingTech. Fold out, build up. Instead of building a glass house, as was initially planned - but which was difficult to get to comply with the energy requirements of the building regulations - JCN Bolig and the company's subcontractors have thus piled up a completely different type of building using ReBLOCK's from REXCON.

Impact & Result

The common house is thus built with outer walls of flat-packeable ReBLOCK's from the company Rexcon. The boxes for the 105 m2 community house have been laser-cut and screwed together in Hedensted, sent folded to the construction site on only seven EUR pallets. The footprint of the ReBLOCK is -6,2 kg CO2eq per squaremeter wall surface.

Solution Spotlight

The solution aims at providing a sustainable and reusable alternative to the traditional building industry. The patented solution is a sustainable and circular climate screen system that is used for building load-bearing external walls in e.g. residential housings. It consists of load-bearing modular frames made of wood, which help to ensure a healthy and stable indoor climate all year round, as well as operating savings of approx. 6% due to its innovative product design. A product design that, in addition to operational savings, also enables a total 22.7 m2 climate screen to be delivered within the framework of one EUR pallet. This feature means that external wall solutions for 4 houses of 140 square meters each can be delivered with just one truck delivery. The solution, therefore, contributes to CO2 reduction in both the choice of materials, the delivery, the operation, and the possibility of recycling the product as it is designed for disassembly and direct reuse.
