Operational and maintenance costs in passive houses and low energy houses
How much energy does a passive house actually save? Does a passive house pay-off by itself? What are the costs for maintancence? For the first time an approximation for the running costs of a passive house were systematically documented and compared.
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.
Reduction of maintenance costs of ventilation systems in plus energy buildings
Maintenance costs for central air ventilation systems are approximately 0,42 Euro/m².a excluding VAT, for decentralized systems 1,16 Euro/m².a excluding VAT. 50% savings in operating costs of apartment passive houses opposed to apartment low-energy buildings [SCH11] can be achieved with maintenance costs of around 0,42 Euro/m².a.
Energy relevant and ecological monitoring studies of demonstration buildings, which were built in the framework of the program "Haus der Zukunft".
Energy relevant and ecological monitoring studies of demonstration buildings, which were built in the framework of the program "Haus der Zukunft". The user acceptance should also be levied and displayed
Booklet issued by Building of Tomorrow with about 20 practical passive house thermal bridges free connection details for large-volume residential buildings
In particular, for buildings with very low energy consumption on heating the influence of heat bridges have a special value. Since in passive house construction a largely heat bridge free execution is required, the most frequent and significant heat bridges are collected in a booklet.
Gründerzeit with future - demonstration project 3: KA 7 Kaiserstraße - Innovative renovation of a listed Gründerzeit building
A demonstration of how innovative measures, with highly efficient and contemporary standards and taking into consideration comfort and energy consumption, can be applied to a heritage listed building.
Comfort ventilation plus+: First time development of high efficient comfort ventilation systems that enable demand-control of room-wise airflow for new buildings and refurbishment
First time development of innovative components for comfort ventilation systems used in new buildings and renovation that enable demand-control of air flow room-wise. The outcome is a considerable reduction of the primary energy balance and a sustainable solution of problems concerning the discrepance between satisfying humidity and very good indoor air quality within the heating period.
Gründerzeit with future - demonstration project 2: ROOFJET Wißgrillgasse - sustainable solution for improving the thermal-energetic performance of a typical historical building in Vienna
The main aim of the project ROOFJET Wißgrillgasse is a building refurbishment by a factor of 8 which demonstrates that even historical buildings can be refurbished to lowest energy standard.This demonstration project shows a holistic and sustainable refurbishment concept for a special type of buildings with innovative technical and organizational solutions.
