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.
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.
Evaluation of mechanical class room ventilation systems in Austria and generation of a planning guideline
Accumulation of technical solutions and practical experience of schools (kindergarten) with mechanical ventilation systems and identification of how pupils and teachers accept the systems.
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.
SQUARE - A System for Quality Assurance when Retrofitting Existing Buildings to Energy Efficient Buildings
The project aims to promote a flexible quality assurance management for the retrofitting process. It leads to high quality renovations of residential multifamily buildings regarding energy improvement and improvement of indoor environment.
A robust, predictive controller which utilises weather forecast data to control thermally active building systems had been designed, researched and assessed in terms of energy efficiency and comfort compared to standard controllers, especially for cooling purposes. Simulations and real measurements using two "Test-Boxes" with thermally active building systems which are constructed and built for this purpose were used to analyse energy efficiency and comfort. Low complexity and transparency of methods and solutions should allow for transferability of all results to guarantee maximum usability for similar applications.
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.
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.
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.
Many traffic areas in urban environments are actually used as such only a small fraction of the time. Subject of this project was to investigate the possibility of using those areas by additional integration of photobioreactors for the production of biomass, integrating such systems to the maximum extent into the urban substance and energy cycles.
CoolAIR - Predictive control of natural nighttime ventilation and daylight-optimized shading for passive building cooling
Natural nighttime ventilation and daylight-optimized shadowing are high potential approaches to efficiently and economical cool buildings. Nevertheless, the full potential cannot be acquired, since, if at all, such behavior is manually initiated by users. Goal of this project is the development of an automated, self-learning system that can assess the full cooling capabilities and establish an alternative to conventional air conditioning systems.
EnerPHit-green concept Modernisation of a historic building with application of an aerogel insulation plaster
This demonstration project shows the comprehensive modernization of a historic building within the constraints of a regional protection zone. By using the Aerogel high-performance insulating plaster, a comprehensive energy-efficient building refurbishment had been realized without changing the outer appearance of the façade.
SPACE4free - Retrofitting souterrain areas in 19th century townhouses to apartments with high quality of life and low energy consumption
Planning of durable and damage-free apartments with high quality of life and low energy consumption in moisture exposed souterrain areas of 19th century townhouses. Using innovative ventilation control systems comfortable room climate will be created. Additionally the tolerance of different types of use is ensured. A planning tool enables the scaling of the findings and thus the applicability to various planning situations.
greening UP! Sustainable green maintenance, maintenance, maintenance of vertical greenery including legal aspects
Based on extensive surveys and analyses of existing vertical building greenery in outdoor areas (floor and system-bound façade greening) and vertical interior greenery, the project develops tailor-made green care, maintenance and repair concepts and addresses legal aspects. The "greening UP!" Knowledge pool with concrete recommendations and clearly presented findings as well as the conception of a digital tool for the "First Green Aid" complete the project.
E.Vent – Efficient, cost-effective and low-maintenance central ventilation systems for multi-family housing – Design, operation and fire protection measures
Die Synopsis ist eine drei- bis vierzeilige Beschreibung des Projektinhalts alsErgänzung zum Titel und nähere Erläuterung des Projekts.
The motivation for developing the project "Clay Passiv Office-Building Tattendorf" was the dissatisfaction with the situation of a great difference in the state of technology in three fields relevant to the research project: 1) sustainable production of energy , 2) sustainable energy conservation technologies and 3) use of sustainable building materials.
An integrated technical energy plus office concept without additional building costs demonstrates the feasibility of such projects instancing a concrete office project with 50.000 m² floor area in Vienna with economical cost consideration.
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.
Development and implementation of contributions to the quality control of innovative technologies in the areas of building services and insulation that are derived substantially from HAUSderZukunft findings.
Energybase is a showcase project in terms of energy efficiency and use of renewable energies realized by the Vienna business agency. With 7.500 sqm net floor area ENERGYbase provides space for innovative business and research and development on the field of green energy.
