BIGMODERN - Subproject 8: Demonstration building Amtshaus Bruck - Realisation

In the frame of the flagship project BIGMODERN the "Amtshaus Bruck an der Mur" had been renovated according to above-average quality standards concerning energy efficiency and sustainability while complying with an industrial management point of view.

Short Description

This project is a sub project of the flagship project "BIGMODERN - Sustainable modernization standards for buildings owned by the Federal Republic of Austria from the 1950s to the 1980s"

Status

completed

Abstract

Starting point/Motivation

This subproject, as being part of the flagship project BIGMODERN, documents the realized measures of one of the demoprojects (office building Bruck an der Mur).

To reach sustainable refurbish-standards in practice, there have to be greater changes in different technologies. Innovative technologies in the context of modernization mean additional efforts in planning and coordination, which is hardly possible in the standard planning process. Changes to the standard planning process and to the technologies used imply risks for the building owner like exploding costs, less savings than planned in operation and susceptibility to failure. To get innovations to reach modernization-standards, these risks have to be minimized.

The core element of the flagship project is the implementation of two demonstration projects, which should be modernized especially for the Bundesimmobiliengesellschaft m.b.H. (BIG) according to above-average quality standards concerning energy efficiency and sustainability while complying with an industrial management point of view. This is supposed to raise awareness of the BIG breaking new ground in order to maintain innovative and yet cost-effective renovations.

The aim is to set new standards in conventional renovation and to tap into the BIG's full potential with regard to implementation.

Contents and Objectives

The aim of this sub-project is to gather information/experience from pilot projects, to be directly used in the planning and decision-making process of the building owner Bundesimmobiliengesellschaft (BIG) and other building owners. Against this background, the sub-project documents the measures implemented in the demonstration project:

  • Demonstration of how far the modernization of a federal office building in high thermal-energetic quality is feasible;
  • Starting from the BIG's basic commitment to build the demonstration building to high quality standards, a specification of the quality requirements for energy efficiency and sustainability for the specific modernization projects should be carried out (shown in the outline of BIGMODERN subproject 1);
  • Design and monitoring of planning processes in such a way that the required quality standards are not "lost" during the planning process (edited in detail in BIGMODERN subproject 2);
  • Based on the "lessons learned" in the demonstration project, a basis for generalizable conclusions and recommendations for further project planning is created as a result of the core BIGMODERN subproject 4

Results

This project represents a first step in the implementation of outstanding energy projects. In upcoming renovations from the ARE/BIG the objectives of BIGMODERN will be further supported and optimized on the basis of experience from the demonstration project. Despite difficulties and challenges the converted project represents a shining example of energetic standards in modernisations.

It is not only important to implement the overall control of the integrated planning process, but also to control the commissioning and operation of the plant in the first phase after implementation. It showed that despite very good and integrated planning, weaknesses and errors can occur during the operation of the plants, which remain undetected in the absence of operation-management and therefore the savings targets can be missed.

According to BIG's existing leases the type of operation-management is not regulated in detail. The tenants are generally responsible for the operational management. With new buildings and building control, the tenants are faced with a new challenge. In the future operational management should already be regulated for energy efficient retrofit projects before starting the planning process. When handing over the building to the tenants, the operator should be trained (EVM), so that he can respond to faults in the control and optimize the building from the information provided by energy consumption monitoring.
