IEA-DHC Annex TS2: Implementation of Low Temperature District Heating Systems
The potential of alternative heat sources is highest at low system temperatures, but current district heating networks are usually high-temperature systems. The aim of the IEA DHC Annex TS2 is to support the transformation of district heating networks towards lower temperatures (the so-called 4th generation). For this purpose, Annex TS2 forms an international platform that enables an exchange on the topics of technology, system, demonstration and competitiveness.
IEA SHC PVT Task 60: Applications of Photovoltaic/thermal (PVT) Systems and New Fields of Application and Examples of PVT
The international research collaboration IEA SHC Task 60 (Application of PVT Collectors) identified existing applications for PVT technologies and evaluated and highlighted potential system solutions where PVT technology has clear advantages over separate installation of PV modules and solar thermal collectors. In analogy, their advantages and current barriers for a broad market acceptance were highlighted.
IEA 4E: Annex Electric Motor Systems. Working period 2017 - 2019
The goal of the Annex Electric Motor Systems is to raise awareness on the large savings potential in motor systems, while showing the realization method of such a path. After publishing the „Policy Guidelines for Electric Motor Systems“ and recommendations for carrying out energy audits for motor systems based on international standards Austria analysed the impact of industrial automation on electricity consumption and the motor market.
IEA HPT Annex 51: Acoustic Signatures of Heat Pumps
The aim of the project was to increase the acceptance of heat pumps by reducing their noise emissions and vibrations and to reduce market barriers. Using innovative measurement and data analysis methods, influencing factors on the acoustic emissions of heat pump systems and the impact of acoustic protection measures were investigated. The results were prepared in the form of guidelines and recommendations for action.
IEA HPT Annex 43: Fuel Driven Sorption Heat Pumps
The project aimed at investigating the performance and market potential of gas-fired absorption heat pumps (AHPs) in domestic and small commercial or industrial buildings or applications. Selected processes were simulated for various types of buildings in order to calculate the energetic, ecological and economical potential of this technology. The results were compared with monitoring data of a gas-fired AHP system. In addition, a market survey including market barriers for gas-fired AHPs in Austria was conducted and a list of market supporting measures was compiled.
IEA SHC Task 48: Quality Assurance and Support Measures for Solar Cooling
The completed IEA SHC Task 48 focused on an enhanced quality improvement and market-support measures for the technology option ‘solar thermal cooling or air-conditioning'. In cooperation with a total of 22 organizations (12 research institutes, 5 universities and 5 companies) from eight countries numerous useful reports and tools have been created to improve the quality of solar cooling systems with significant contribution of the Austrian partners.
IEA EBC Annex 62: Ventilative Cooling
The main goal of the Annex 62 is to make ventilative cooling an attractive and energy efficient cooling solution to avoid overheating in buildings. Ventilation is already present in buildings through mechanical and/or natural systems and it can remove excess heat gains as well as increase air velocities to widen the thermal comfort range. The results from the Annex facilitate better possibilities for both design purposes and for energy performance calculation.
IEA HPT Annex 49: Design and integration of heat pumps for nZEB
A dominating concept to reach a nearly Zero Energy Building (nZEB) is the combination of solar PV systems and heat pumps. The extended scope of the Annex 49 regards the balance of single buildings and groups of buildings/neighbourhoods, a thorough investigation of heat pump integration options for nZEBs and nZE neighbourhoods by means of monitoring and simulation as well as the design and control optimization for heat pumps in nZEB and the integration into energy systems.
IEA EBC Annex 73: Towards Net Zero Energy Resilient Public Communities
Public buildings such as hospitals and educational institutions often house critical infrastructure that depends on sufficient energy and resource supply. The aim of the annex was to develop tools for the planning process of resilient, efficient and low-emission energy systems for such building clusters.
IEA EBC Annex 71: Building Energy Performance Assessment Based on In-situ Measurements
The requirements on building envelope and on building technology are steadily increasing. There is a lack of measurement and analysis methods to control the quality of the built implementation and to optimize the building operation. This project developed a methodological basis to enable an in-situ evaluation of the actual energy performance and building operation. For this purpose, it investigated methods to generate data-driven building models favouring the use of already available on-board data.
IEA EBC Annex 72: Assessing life cycle related environmental impacts caused by buildings
The construction sector has great potential to reduce its energy consumption and the associated environmental impacts. The IEA EBC Annex 72 therefore focuses on the harmonization of methods for the assessment of construction-specific and operational environmental impacts (primary energy requirements, greenhouse gas emissions and other indicators) throughout the life cycle of buildings.
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.
IEA SHC Task 59/EBC Annex 76: Deep Renovation of Historic Buildings - Towards lowest possible energy demand and CO2 emission (nZEB)
The goal of Task 59 was to document international best practice examples (knowledge base), develop a multidisciplinary planning process, and develop holistic retrofit solutions for historic buildings. As a knowledge base, the Historic Building Retrofit Atlas (www.HiBERatlas.com) emerged from the project. In the HiBERatlas more than 55 best practice examples are documented. In addition to the management of Subtask A (Knowledge Base) and Subtask C (Conservation compatible retrofit solutions & strategies), innovative technical and organizational retrofit solutions, which have already been applied in national demonstration projects and tested in practice, have been incorporated and further developed through the Austrian participation.
IEA SHC Task 53: New Generation Solar Cooling & Heating Systems
Within the framework of the IEA SHC Task 53 'New Generation (NG) Solar Cooling & Heating Systems', solar-electric and solar-thermal air-conditioning systems were investigated. The main objective was the development and documentation of reliable and economical NG system solutions. A comprehensive comparison of different NG systems as well as the elaboration of support measures for the market launch are core results of the international cooperation.
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.
IEA AFC Annex 31: Polymer Electrolyte Fuel Cells
Task 31 was a research and development oriented Task with the objective to contribute to the identification and development of techniques and materials to reduce the cost and improve the durability of polymer electrolyte fuel cells (PEFCs).
