Analysis and evaluation of structural additional costs for passive house projects

Structural extra costs of passive houses decide whether these will become accepted at the market. Within the project the costs of several "Building of tomorrow" passive houses were compared. The results enable estimations for future passive house projects.

Can sustainable building be realized at reasonable costs?

At the development "residential Passive House Utendorfgasse" were reached very low building costs. Would there be different building costs by using ecological materials and technologies? There will be calculated additional and reduced costs by using the ecological building-catalogue and internal characteristic values of projects that are similar in design.

Gründerzeit with future - sub project 2: Foundations and feasibility studies

Documentation of available knowledge on the renovation of historical buildings ("Gründerzeitgebäude") as an input for the preparation of 5 demonstration projects as well as the development of an accompanying monitoring system within the scope of the project "Gründerzeit with future".

Optimisation of ecological construction components for industrial serial production of precast elements

The project focused on passive house elements from straw and clay. Special interest was paid at a novel straw insulation as well as at an efficient drying process of the clay. Sustainability of the building materials was a very important aspect within the project.

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.

EKZ - EnergieKompetenzZentrum Großschönau: "Sonnenplatz - 1. European passive house village for test-living" phase of realisation

Integrative approach for the diffusion of the ecologic passive house: village of passive houses for test-living with an Energy Competence Centre on the basis of a sustainable concept for settlement development at Großschönau.

BONSEI! Optimal use of existing buildings – energy efficient implementation of renovation!

The project BONSEI! would like to support an energy efficient and socially acceptable densification of privately owned residential buildings in urban space and to develop a methodological basis for resource efficient urban areas. The results are used for the conception of an innovative service in order to provide a neutral consulting regarding private densification plans.

WohnMOBIL - Innovative living and transport options in areas with high settlement pressure

The objective of the WohnMOBIL project is the promotion of a land-, cost- and traffic saving settlement development and a change of transport priorities (priority of eco-mobility). This shall be reached by the transfer of innovative living concepts like "transitory living", until now mainly used in urban areas, to suburban-rural areas and the interrelation with needs-oriented multimodal mobility concepts.

The very first reconstruction in Austria of a one-unit house to passive house standard (Model project in Pettenbach/Upper Austria)

The main objective is the unprecedented reconstruction of older one-unit buildings to the standards of passive houses. The reconstruction estates are of the numerous older one-unit houses in Austria. The reconstruction will considerably enhance the convenience of living quarters in the old houses.

Exploration of window systems with innovative glass - especially vacuum insulating glass - for building renovation

Exploration of the use of the first fabricable highly insulating vacuum glazing (VG) for highly efficient window systems specifically for the renovation of existing buildings via Verification of the availability and performance of Vacuum Glazing VG worldwide, concepts for structural optimization and thermal simulations of integrated systems, investigation of typical applications and market potential studies and identification of achievable energy savings for single buildings and settlements.

thermocollect: realisation of a plus energy building by a solar active facade system

The project demonstrates the application of a solar active facade system in the course of the renovation of an existing building in order to achieve the plus-energy standard. Moreover, the effectiveness of the system will be demonstrated on new buildings and transparent compo­nents as well. The final outcome will be a manual for the application and implemen­tation of the façade system focusing on the segment of specialists and skilled labour.

Single Family Homes and Densified Low-rise Housing - an Analysis of Motives

The study concentrates on describing the reasons behind the slow uptake of space-saving, densified forms of housing, and explains the dominant preference for detached single-family homes. However, it goes beyond simply describing the decisive motives for choices of housing. The study analyses the determining factors and the basic conditions under which these motives come or came into being. Based on this analysis, alternatives will be proposed and evaluated with regard to their effectiveness and feasibility.

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 %.

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.
