IEA SHC Task 61/EBC Annex 77: Integrated Solutions for Daylighting and Electric Lighting

Lighting accounts for around 15% of global electricity consumption - intelligent coordination of daylighting and electric lighting solutions together with integral lighting controls enable significant energy savings. At the same time, the solutions must be optimally planned in a user-centered approach based on the visual and non-visual effects of light. The task analysed user requirements as well as existing technologies and design methods and documented exemplary implementations in case studies.

Online reference for ecologically rated building construction details suitable for achieving Passivhaus standard

An already well-established web database management system is being adapted to present the contents of a catalogue of building elements for the Passivhaus standard. A wider distribution of the contents and future extensions of the catalogue by distributed workgroups are the promises of the project.

Study of the Potential of Popcorn-Technologies for the Austrian Energy System

"gugler! build & print triple zero" - Subproject 7: Integrated General Planning

The aim of the subproject 7 is to aggregate a "normal" general planning process with innovative additional services. In the spirit of integrated planning in the design a higher number of design parameters must be resolved. This is different to a classic planning process with linear and chronological lined up add ons.

Pioneer region for Smart Grids in Vorarlberg: International Connection

Inhabitants-friendly passive house renovation in Klosterneuburg / Kierling

Renovation of an apartment house from the 1970s as passive house using renewable energy.

Quality criteria for the Building of Tomorrow

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.

Climate neutral Wiener Neustadt 2040

Wiener Neustadt wants to develop its own vision and implementation strategy for climate neutrality by 2040 and develop it in four steps.

SUBURBAHN – test- and demonstration-area for urban development and mobility around public transport stations in the central area of Upper Austria

Targeted, process-oriented conception for the implementation and operation of a test- and demonstration-area for urban development and mobility in Ansfelden involving relevant scientific stakeholders, local and regional stakeholders, decision-makers as well as the interested public according to the living lab approach.

BIGMODERN - Sustainable refurbishment standards of federal buildings constructed between 1950 and 1980

The project aims at developing sustainability and climate protection criteria for the refurbishment of federal buildings of the postwar period. These criteria will be tested for their practical suitability within the framework of demonstration projects. Subsequently, these criteria will be defined as fundamental guiding principles in the planning and building processes for all future BIG retrofit projects.

3D*3B - 3D-Concret Printing, Reinforcement for low carbon and bending stressed structures.

The project is about 3D printed structural elements and their integration in building structures. The focus is predominantly set on bending stresses structural elements like panels and slabs. Results will point out technical, logistic and climate relevant aspects.

Open Innovation

Instruments and Strategies for the involvement of users and other relevant social groups in the design process: the example of fuel cell technology in end-user markets and wood-plastic composites.

Renew Building - Competence Building and Knowledge Transfer for Climate-friendly renovation with ecological and renewable materials

The project Renew Building provided knowledge about eco-friendly renovation to the target groups (planners, architects, students of architecture, etc.) through theory and practice classes, lectures, an e-learning platform, and in an online knowledge database.

Sustainable ventilation systems in multi story residential buildings in the conflict areas of hygiene and costs

The goal of this project was to develop guidelines for hygienic and cost-efficient mechanical ventilation systems in residential buildings, in which maintenance and cleaning demands are described. These guide­lines are based on existing literature as well as practical experience of the property owners, finally they are based on results of hygienic measurements in existing ventilation systems conducted in this research project.

"gugler! build & print triple zero" - subproject 5: Ecoeffective building

On the basis of the commercial building gugler with 2140 m² useable floor area existing and 3260 m² useable floor area to be built a concept for a 100% recyclable ecoeffective building will be developed.

IEA EBC Annex 75: Cost-effective Building Renovation at District Level Combining Energy Efficiency & Renewables

For the conversion of existing buildings into low(st) energy buildings with low greenhouse gas emissions, it is important to know which strategies are most cost-effective to reduce emissions and primary energy consumption of the buildings. In particular, it is important to find the right balance between energy efficiency measures and renewable energy measures. This question is addressed in this project.

FiTNeS - Facade integrated modular Split-heat pump for new buildings and refurbishment

The goal of FitNeS was the development of modular split heat pumps with compact and silent façade-integrated outdoor units for heating and domestic hot water preparation (and optionally cooling in combination with PV). The outstanding features of the concept are a modular design with a high degree of prefabrication and representing a visually and architectonically attractive, economic and sustainable solution for both new constructions and renovations. One of the main development goals is the minimization of sound emissions by means of optimized flow control.

LightCycle

Fiber-reinforced thermoplastic composite components with low weight, so-called lightweight components for transport and mobility, lead to significant CO2 savings. Despite established production technologies and weight savings, further progress in lightweight construction is increasingly difficult because the sustainability of these products is currently not given due to the unresolved recycling problem, although the regulations require, among other things, 85 % recycling of an end-of-life vehicle.

scaleFLEX - Scalable method for optimizing the energy flexibility of districts

Development of a decentrally organized automation method for improving the demand-side flexibility options of buildings and districts. The utilized data-driven algorithm promise high scalability and therefore low installation and operating costs. The developed method will be validated using different building types (high-tech office buildings, low-tech office buildings, residential buildings).

IEA-ISGAN Annex 1: Global Smart Grid Inventory IEA-ISGAN and Annex 2: Smart Grid Case Studies

The international Smart Grid Action Network (ISGAN) aims to improve the understanding of Smart-Grid-technologies and to accelerate global deployment. The work in ISGAN is structured in eight standing working groups (annexes). The present project describes the Austrian contribution to Annex 1: Smart Grids Inventory and Annex 2: Smart Grids Case Studies.
