LifeCycle Tower - Energy efficient prefabricated multi-storey timber houses

Based on the results of previous research projects, the project at hand deals with the development of a wooden prefabricated module construction for energy efficient office buildings with up to 20 storeys. This sustainable system ensures cost certainty through the whole life cycle of the building.

Titel und Synopse

LifeCycle Tower - Energieeffizientes Holzhochhaus in Systembauweise

Aufbauend auf den Ergebnissen vorangegangener Forschungsarbeiten wird im vorliegenden Projekt ein Holzfertigteil-Baukastensystem zur Errichtung energieeffizienter Bürohochhäuser mit bis zu 20 Geschoßen entwickelt, das sowohl nachhaltig ist, als auch Kostensicherheit während des gesamten Lebenszyklus bietet.

Summary

Starting point / motivation

Based on the results of the research project "eight plus phase 1" it is clearly possible to build an 8 storey timber house as well as to ensure its economic efficiency. The aim of LifeCycle Tower is to obtain maximum economic efficiency, at the same time develop a standardized system for prefabricated buildings. Main features for sustainable building development and Rating were defined within the projects "Immo-Rate" and "inkl.wohnen".

Contents and goals

All targets set for this project are highly ambitious. A multi storey complex incorporating up to 20 floors with a timber structure is meant to be erected. Additionally, the timber building will profit from the energy efficient way of building and the unique facade system, changing it from being an energy consuming property to an energy generating property. The building is mainly developed in a building-block type of system to secure clear cost structures, resulting in a future oriented product incorporating all aspects for a sustainable town development. This will be extremely interesting for investors as well as for city/town planners.

The entire complete system which will be brought to market on an international level consists of three closely linked components; facility management, facade and construction. By introducing an integral planning process both economical and ecological factors have similar impact on the product, whereby the environmental impact of the product is measured by CO2 quantifications followed by certifications.

The economical and ecological aspects are to be considered in a project of this nature. Timber will be an extremely attractive material for the construction industry, due to current and future rising energy and raw material costs. A further focus of this project will be on life cycle costs, i.e. running costs. New ideas will be generated to keep running costs low and further optimize the life cycle of a property.

A high rise building which is defined by energy saving concepts and simple timber building-block systems follow the philosophy of sustainability, which is the future.

Expected results

Following results are expected to be available in the end of the project:

  • A comprehensive building concept for construction, facility management and façade
  • A wooden prefabricated module construction as a new product that meets the requirements in terms of fire protection, acoustics as well as carrying capacity.
  • A non-product and non-producer related building automation layout including a façade concept
  • A design for a plus-energy building
  • Life-cycle orientated economic calculations
  • Evaluation of the CO2 balance and certification
