IEA SHC Task 37: Advanced Housing Renovation with Solar & Conservation
Development of advanced renovation concepts for residential buildings. For the housing segments with the greatest energy saving potentials strategies for increased market penetration of advanced housing renovation are investigated. Analysing outstanding renovation projects shall lead to technically and economically robust and sustainable concepts for housing renovation.
Certified passive attic conversion of a typical building from the period around 1900
Conversion of an attic of a typical building from the period about 1900 to a passive attic with photovoltaic system and renovation of the existing building equipment. The aim is to keep the additional construction costs under 10 %, to avoid overheating in summer and to make possible a reproduction for the large amount of buildings from the same period.
Climate neutral buildings from the period of promoterism - ways, potentials and possibilities of implementation
The focus was on the goal-oriented and economic options, in order to achieve a CO2-neutral energy supply and hermetically sealed building envelope as well as to show high energy efficiency when using. On the other hand building protection regulations and the quality in use are to be considered.
plusFacades - International know-how- and knowledge transfer of "intelligent Facade systems" for Austrian players and key personnel
The project proceeds from the idea that prefabricated intelligent facade systems represent a promising technology for the energy efficient refurbishment of buildings. A goal is to process the present international state-of-the-art and the existing know-how to this topic for Austrian experts.
PHOTOVOLTAIC WATER Solution
Passive House refurbishment facade with integrated photovoltaic modules for direct, current-based warm water preheating. The GIWOG, an energy-conscious and environmentally and socially oriented client, intends to undertake an energy-related modernisation project, which will further optimise energy consumption to be more efficient at an apartment complex in Graz, main street 302-306. The goal is to lower the energy consumption for heating and hot water from the current level of approximately 135 kWh /m²a to approximately 8 kWh /m²a. The planned measures should correspond with an overall energy consumption reduction of approx. 94 %.
WHISCERS. Whole House In-Situ Carbon & Emission Reduction Solution
Whiscers is a system for installing internal wall insulation with minimal mess, whilst the resident remains in the property. It involves measuring the walls in the property using a laser device that enables fast and highly accurate measurement. Information is then sent electronically to a computer controlled off-site cutting machine that is rapid, precise and mess-free.
Mechanical ventilation system for windows for the renovation of old buildings
Analysis and implementation of alternative ventilation systems for windows, focusing on thermal renovation of old buildings. The investigated ventilation systems were presented to an expert group. The aim was to discuss ventilation technologies with the help of different aspects and to develop a SWOT analysis.
e80^3-Buildings - Sub project 4: Demonstration object
Alongside the realisation of the plus energy building in Kapfenberg, a demonstration project is scheduled to be created that accomplishes an economically viable and technically innovative solution for the future.
e80^3-Buildings - Sub project 1: Basics
Goal of this subproject was to select the building with the highest potential within a building-portfolio. Therefore a criteria catalogue was developed, which is generally applicable.
Catalogue of Passivhouse Details for Refurbishments
A Catalogue of Passivhouse Details for Refurbishments for buildings of all building periods from the 1870 to the 1980s. Special consideration to the refurbishment of building parts in contact with the earth. Integration of controlled ventilation services. Construction elements description with drawings, building physical data and ecological life cycle assessment. This project aimed at contributing to "Replicable refurbishment concepts for meeting passive house (or comparable) standard in buildings of all building periods".
Gründerzeit with future - demonstration project 1: David´s Corner
High value energy efficient refurbishment of an ensemble of three neighbouring Wilhelminian style buildings in a non-lucrative location.
Building of Tomorrow for the construction industry
Dissemination of results of the research initiative "Building of tomorrow" for two specific target groups - master builder and installer - implementation in further vocational training concepts
Serial refurbishment for buildings in timber construction
Refurbishment of single- and two-familiy houses in timber construction in Austria has a large CO2-saving potential. To meet the special requirements for the refurbishment of timber constructions, a concept for the renovation to passive house respectively plus-energy house standard with special focus on ecologic construction materials was developed in this project.
e-retrofit kit - tool kit for passive house retrofit
Development of an internet-based tool for passive house retrofit für - target group social housing companies. Actualization of tool after test and evaluation in case-studies. dissemination activities in austria.
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.
Evaluation of temperature differentiation on a room-by-room basis in passive house apartments
In the passive house Utendorfgasse a room–by-room temperature control was installed in 11 apartments. The experiences were evaluated from a technological and from a sociological point of view.
Urban consolidation Lehen - Subproject 8a: project management - documentation - dissemination and quality assurance
The project coordinates several projects in the urban quarter Lehen to ensure increase of energy efficiency and sustainable development. This subproject contains the coordination of the partners and projects in order to reach defined standards of quality, coordination and cooperation with the program "Building of Tomorrow" and other flagship projects as well as the documentation of results.
School vent cool - Ventilation, cooling and strategies for high performance school renovations
Based on a building typology, strategies for prefabrication for high-quality thermic-energetic renovation of school buildings were developed.
