A Pattern Building in Turu 21, Estonia

Renee Puusepp

Description

A modular redesign of a concrete office building originally designed by KTA architects. The new design features 3D LVL modules and is produced off-site. The team of authors: Egle Vogt, Lauri Läänelaid, Renee Puusepp, Marianna Zvereva, Eero Tuhkanen, Kristo Kalbe

Key benefit

Reduction of the embodied carbon footprint by 1/3

Material list

LVL, CLT, concrete, stone wool, dried lumber, glass, steel, copper, PVC

Ecological values

The redesign reduces the embodied carbon footprint by 86kg CO2e/m2 as compared to the original design, saving nearly 270 tonnes of CO2e in total. The design works as a carbon sink.

    Technicaly very high design solution by using modules for this kind of building. The 3 module sizes enable a good divison of space of the buidling. The twist-lock connection of the moduls provide a fast and precise fitting on-site, while the moduls can be manufactured down to last details, off-site.

    This Hybrid City competition entry is based on 3 Kerto based module sizes with one defined steel based ISO corner connection similar to freight containers. The external facade has a concrete type finish or a full glass front. The entry includes details, principles of service distribution and a Life Cycle analysis in comparison with the same building design in traditional concrete. Most of the opaque structure is replaced by engineered wood material. It is an excellent example of a modular engineered wood construction.

    The idea really focuses on modular building, In particular, I'm a fan of the clever connector designed to transfer forces in the corners. A key issue in modular multi-storey buildings...congrats for that!
