Collaboration between IEA EBC ventilation related annexes

Ventilation and air infiltration into buildings represent a substantial energy demand which can account for between 25% to over 50% of a building's total space heating (or cooling) needs. Unnecessary or excessive air change can therefore have an important impact on global energy use. On the other hand insufficient ventilation may result in poor indoor air quality, with consequential health problems, or poor thermal comfort. Designing for optimum ventilation performance is hence a vital part of building design.


New AIVC Technote on ventilation and health

AIVC is preparing a Technote on Residential Ventilation and Health. The Technote is now under review by the AIVC. Providing good indoor air quality to home occupants can have a substantial impact on occupant health and ventilation is a key tool for achieving that goal.


EBC Newsletter, June 2015, is now available

The Energy in Buildings and Communities (EBC) newsletter carries regular reports of energy policy development and research activities taking place in various countries. It contains updates on ongoing and planned research projects, features new publications and website information, as well as topical articles of a general nature. It is intended for those active in fields relating to operational energy saving for buildings and communities.

The EBC news Issue 61, June 2015 contains the following articles:


7-9 December 2015, Conference, Hyderabad - Building Simulation Conference 2015

The 14th International Conference of the International Building Performance Simulation Association (IBPSA) - Building Simulation Conference 2015 (BS2015)- will focus on advancing the practice in diverse disciplines of building energy analysis and performance simulation. The event is intended for those working in or learning about the field of building performance simulation including building designers, architects, design engineers and consultants, researchers, developers, building physicists, sustainability managers, building operators and regulators specifying simulation as an assessment


New BPIE report released: " Indoor Air Quality, Thermal Comfort and Daylight"

This report deals with Indoor Air Quality (IAQ), thermal comfort and daylight requirements in Belgium (Brussels Region), Denmark, France, Germany, Italy, Poland, Sweden and the UK (England and Wales) and focuses on the respective building codes for new and existing residential buildings.


New publication of the EBC Annex 52 / SHC Task 40: ‘Modeling, Design, and Optimization of Net-Zero Energy Buildings’

A new  publication was released in the framework of the International Energy Agency's Solar Heating and Cooling (SHC) Programme and the Energy in Buildings and Communities (EBC) Programme through the joint SHC Task 40/EBC Annex 52: “Towards net zero energy solar buildings”.

The report aims at assisting designers in optimally using simulation tools for Net ZEB design. It includes advanced modeling techniques as well as detailed case studies. In particular, it:


IEA EBC releases its annual report of 2014

This report presents an overview of progress made by the International Energy Agency (IEA) Implementing Agreement on Energy in Buildings and Communities Programme, including summaries of new, ongoing and recently completed projects.

The IEA-EBC Programme is an international energy research and innovation programme in the buildings and communities field. It enables collaborative R&D projects among its 26 member countries. It provides high quality scientific reports and summary information for policy makers.

16-17 March 2015, Workshop, Lund, Sweden

Around 55 participants from 16 countries attended the international workshop on “Ventilation and Airtightness in Buildings : Voluntary and Regulatory Frameworks to Improve Quality and Compliance” which was held in Lund, Sweden on March 16-17, 2015.  

One topic of specific attention was schemes implemented in various countries to reduce errors in ventilation and airtightness input data used in energy performance certificates and to improve the quality of the works. Discussions were based on analyses of lessons learnt from field data.

Specific sessions included:
