IEA EBC Annex 79: Occupant-Centric Building Design and Operation

The IEA EBC Annex 79 aims to provide new insights into comfort-related occupant behaviour in buildings and its impact on building energy performance as well as occupant-centric building design and operation.

IEA EBC Annex 80: Resilient Cooling for Residential and Small Non-Residential Buildings

The rapidly increasing cooling demand for buildings - internationally as well as in Austria - requires further development and application of low energy and low carbon cooling solutions on a large scale. The Annex 80 is meeting this challenge boosting the development and implementation of appropriate cooling solutions by transferring knowledge and coordinating international research endeavours.

IEA EBC Working Group on Cities and Communities (WGCC)

The WGCC enables information and experience exchange, the identification of bottlenecks that lead to specific research questions and a direct communication with cities on their needs, to enable them to transform their energy systems. The working group is a joint initiative across several TCPs with in-depth participation of technical and non-technical (external) experts.

IEA EBC Annex 73: Towards Net Zero Energy Resilient Public Communities

Clusters of public buildings like hospitals or university campuses often include critical infrastructure which relies on sufficient energy supply. The Annex aims at developing tools for the planning process of resilient, efficient and low carbon 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 monitoring and analysis methods to control the quality of the built implementation. The objective is to provide methods for an on-site (in situ) assessment of the actual energy performance. Based on the results from EBC Annex 58, this Annex takes the step towards practicable characterization procedures.

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. Therefore. the IEA EBC Annex 72 focuses on the harmonization of methods for the assessment of construction-specific and operational environmental impacts (primary energy requirements, greenhouse gas emissions and otherindicators) throughout the life cycle of buildings.

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

For the transformation of existing buildings to nearly zero energy buildings with low greenhouse gas emissions it is important to know which strategy is most cost efficient to reduce primary energy demand and greenhouse gas emissions of the buildings. Especially the right balance between renewable energy measures und energy efficiency measures is of high importance. To give an answer to this topic is goal of this project.

IEA SHC Task 59/EBC Annex 76: Deep Renovation of Historic Buildings - Towards lowest possible energy demand and CO2 emission (nZEB)

The aim of IEA SHC Task 59/EBC Annex 76 is the documentation of best practice examples, the development of a multidisciplinary planning process and the development of holistic reconstruction solutions for historic buildings. In addition to the lead of Subtask A (knowledge base), the Austrian participation will also incorporate and further develop results that have been achieved in national demonstration projects and have been tested in practice.

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

Lighting accounts for 19% of the global electric energy consumption, and major savings can be achieved by intelligently connecting daylighting, electric lighting and control systems. At the same time, optimal visual and non-visual conditions must be provided for the user. Within this project the user requirements for lighting solutions and existing and novel control systems will be analyzed and documented. For evaluation purposes a consistent scheme for the characterization of daylight systems and an hourly rating model for integrated solutions will be worked out. Using a monitoring protocol, implemented integral lighting solutions will be evaluated in lab and field studies.

IEA EBC Annex 70: Building Energy Epidemiology: Analysis of Real Building Energy Use at Scale

Annex 70 will focus on identifying, reviewing, evaluating and producing leading edge methods for studying and modelling the building stock including: data collection techniques on energy use, building features and building morphology; analysis of smart meter energy data, building systems, and user behaviour; and modelling energy demand among sub-national and national building stocks.

IEA EBC Annex 66: Definition and Simulation of Occupant Behavior in Buildings

Given the considerable implications of occupants' presence and behavior for buildings’ performance, IEA EBC Annex 66 aims to set up a standard occupant behavior definition platform, establish a quantitative simulation methodology to model occupant behavior in buildings, and understand the influence of occupant behavior on building energy use and the indoor environment.

IEA EBC Annex 68: Indoor Air Quality Design and Control in Low Energy Residential Buildings

It is the aim of Annex 68 to gather and extend the scientific basis and data for a coupled calculation and evaluation of indoor air quality and energy efficiency of residential buildings. Detailed pollutant models will be integrated in energy building simulation to derive design and operational guidelines for energy-efficient buildings.

IEA EBC Annex 55: Reliability of Energy Efficient Building Retrofitting - Probability Assessment of Performance & Cost (RAP-RETRO)

The scope of the project is to develop and provide decision support data and tools for energy retrofitting measures. The tools will be based on probabilistic methodologies for prediction of energy use, life cycle cost and functional performance. The impact of uncertainty on the performance and costs will be considered. Methods based on probability give powerful tools that can provide us with reliable ranges for the outcome.
