e80^3-Buildings - Sub project 3: Development of technology and components

The main objective of the key project "e80^3" was to develop high-performance renovation concepts focusing on plus-energy-buildings. Afterwards these concepts were realized in at least one or two demonstration-projects.

Short Description

This project is a subproject of the flagship project "e80^3-Buildings - Renovation Concepts for Residential Buildings to Plus-Energy Buildings with Prefabricated Active Roof-and Façade Modules, Integrated Building Services and Grid Integration"

Status

completed

Abstract

Starting point/motivation

Based on already realized innovative building of tomorrow projects (Linz, Makartstraße and Graz, Dieselweg) these key- and lighthouse-projects should be further developed, optimized, perfected and go into production. By the advancement of building technology for pre-fabricated façade modules and external innovative modules for up to four-storey buildings, it will be possible in the future to retrofit a great number of buildings to a high standard and also economically.

The facade modules on the one hand contain traditional rear-ventilations and on the other hand energy producing active elements ("plus" energy producer) like solar thermal collectors and photovoltaic power modules. In this way the quantity and the position can be adjusted and optimized according to the given situation (Zero-Energy or Plus-Energy). Innovative modules will be developed to different standards with the help of a skilled producer of building technologies and externally mounted without any framework.

Objectives and contents

The objectives and aims of the sub-project 3 "development of the technology and the components" in the relevant report period are:

  • Development and definition of the basic modules for the façade and the building technology.
  • Assessment of the building physics and the ecology of the modules
  • Preparation of relevant work drawings
  • Calculation of profitability of the modules
  • Production of the prototypes for the façade and the building services
  • Validation of the watertightness of the prototypes

Methods of treatment

Sub-project 3 was divided into five work packages. In each work package different methodical approaches were used:

Development of the basic module

The work in WP 2 included workshops, interviews, discussions with specialist companies and the preparation of work drawings. The basic modules which are developed in WP 2 will be produced und tested as prototypes in WP 3 and 4.

Production of the basic module prototype for the facade

The main focus in WP 3 was on the production of a prototype for pre-fabricated façade elements and the assessment of the building physics. Besides the development, the transport and the assembly of the pre-fabricated façade elements were documented in detail.

Production of the basic module prototype for the building services

Similar to WP "Production of the basic module prototype for the facade", the main focus in this WP was on the production of a prototype for a pre-fabricated basic module for the building services and again the assessment of the building physics. Also development, transport and assembly of the prototype were documented.

Ecological assessment

The objective of WP 5 was the comparison of the ecological quality of the regarded modules depending on assumptions made in the project before.

Co-ordination and dissemination

The aim of WP 6 was the co-ordination of all activities in the sub-project 3 and the dissemination of the results to national and international experts.

Results

The main results of the sub-project 3 were the new developed pre-fabricated modules for the façade and the building services which are innovative, economical as well as they have advantages over the existing and traditional retrofit solutions.

The passive and active facade and home automation modules are an economic and environmental solution and represent an opportunity for the renovation of buildings from the 60's and 70's. The implementation of high-quality thermal renovation and the replacement of the building technology are now possible with a minimum burden on residents.

The use of ecological materials (e.g. the wooden bearing structure) guarantees a sustainable renovation solution.

These new façade modules also provide the opportunity to have a variety of different surfaces (despite pre-fabrication) and to have the building services accessible from the outside. This is an essential step for the future.

By the optimised development of the modules an economical implementation of demonstrations projects will be possible in the future.
