e80^3-Buildings - Sub project 5: Monitoring and dissemination
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"
Context and motivation
The aim of the key project is to develop high quality renovation to plus energy houses and to implement this via a demonstration project. The components which make it possible to achieve a plus energy building after renovation include; high quality thermal renovation of the outer shell using passive house components and concurrent integration of energy producing active elements (thermal collectors, PV,…), and the integration of a network for electricity and heat as a storage function. In this subproject analysis of energy- as well as building-biology-related issues for evaluation and quality management is intended.
Content and aim
The content of the project is the analysis of energy- as well as building-biology-related issues for the evaluation of the demo-project "Sanierung zum Plusenergiegebäude" in Kapfenberg, which was built (constructed) within the program "Haus der Zukunft Plus".
In addition to the aspects of energy and building-biology, the user acceptance is evaluated and shown. The planning stage already has quality intensification in sight, via project-related measures such as planning support for energy- and system-related issues or issues regarding ecological building materials, as well as via the greater involvement of users.
In line with the extended cooperation with architects, building services engineers, operators and users, the control parameters will be optimised so that they correspond to the planned operation of the plant.
Aspects such as the ventilation behaviour, room temperature, air humidity, CO2-concentration in the ambient air or personal contact with internal loads or passive-solar-inputs influence the building performance of low energy or passive houses considerably. Therefore energy-related detailed analysis in conjunction with sociological investigations regarding consumer behaviour should give information about the building’s suitability for daily use.
The energy related evaluation comprises the energy balances throughout the building (plus energy buildings) and also throughout single housing units with special focus on heating energy consumption, hot water consumption, electricity consumption for household appliances and domestic installations as well as comfort parameters like room temperature, air humidity and CO2-concentration in the ambient air considering the actual climate which is recorded by measuring the outside temperature and the solar radiation.
Another work package will evaluate the environmental quality of the buildings by the choice of building materials and the measures taken during the construction as well as in the subsequent use of the building.
With the TQB-planning and evaluation tool, each building will get an environmental identity which enables direct comparison between the buildings.
The project was divided into five work packages which cover different topics, each with specific areas of responsibility. The work packages were structured in such a way that a logical progression within the execution of the project is guaranteed.
Verification of the implemented concept via monitoring and technical measurements as well as the evaluation of the concept itself. The dissemination of the developed concepts through workshops, training courses and conferences to the widest possible audience is a principal requirement in order to promote serial production.
