SaLüH! - Refurbishment of apartment blocks with small flats - Cost-effective technical solutions for ventilation, heating and hot water
Project leader University of Innsbruck: Fabian Ochs
Project staff: Dietmar Siegele, Eleonora Leonardi, Elisabeth Sibille, Toni Calabrese, Georgios Dermentzis
Project partners:
- University of Innsbruck (project management)
- AEE Intec
- SIKO Energy Systems
- J. Pichler
- Vaillant
- Internorm
- Kulmer Holz-Leimbau
Funding organisation: FFG
Duration: 01.09.2015 - 31.08.2018
When refurbishing multi-storey residential buildings, it is often not possible to carry out a complete refurbishment including conversion to centralised ventilation, heating and DHW supply. Especially for residential buildings with small residential units, however, currently available decentralised solutions are also ruled out for reasons of space and cost (see EU project Sinfonia). Therefore, innovative ventilation and heating concepts for refurbishment are to be investigated and space-saving heating and domestic hot water micro heat pumps with outside or exhaust air as a heat source are to be developed for this purpose, which can optionally be integrated into the existing parapet or a curtain-type lightweight timber façade. Wall integration enables a high degree of prefabrication, allows installation even in small flats and minimises the outside and exhaust air ducts. In addition, innovative air routing concepts (e.g. using active overflow), which are to be developed as part of SaLüH!, enable air routing with minimal material and installation costs.

19.06.2018: 2nd workshop and project presentation
Last week, the Energy Efficient Building Unit was able to attract over 40 experts from the building services industry to a one-day workshop on the topic of "FFG project SaLüH! and measurement and evaluation of speed-controlled heat pumps".
Last week, the Energy Efficient Building Unit was able to attract over 40 experts from the building services industry to a one-day workshop.
The all-day workshop was held in two parts. In the morning, Dr Fabian Ochs and Dietmar Siegele presented the FFG project SaLüH! (solutions for ventilation, heating and hot water refurbishment).
In the afternoon, seven experts from Germany, Austria and Switzerland gave keynote speeches on the topic of "Measurement and evaluation of speed-controlled heat pumps". The lively discussions following the presentations showed the interest of domestic industry, housing developers and planners, and that the heat pump will play a central role in a future sustainable energy system.
The SaLüH! project had taken up these impulses in a three-year research project. When refurbishing multi-storey residential buildings, it is often not possible to carry out a complete refurbishment with a switch to centralised ventilation, heating and DHW supply. Innovative ventilation and heating concepts for refurbishment were therefore investigated and space-saving small heating and domestic hot water heat pumps were developed.

03.12.2015: 1st workshop
As part of the SaLüH! project, a three-hour workshop was held at AK Seehof on 3 December 2015 with almost 40 participants. The 1st workshop was dedicated to analysing the needs of the planned projects and developments as part of the FFG project SaLüH! The aim was to obtain feedback from representatives of housing developers, architects, (specialist) planners, manufacturers, energy consultants and scientists on the developments planned in SaLüH! and to recognise possible strengths and weaknesses of the concept at an early stage so that the direction can be adjusted at an early stage of the project. In addition to keynote speeches, there was also a panel discussion followed by an open discussion.
