AIVC - Air Infiltration and Ventilation Centre


AIVC (Air infiltration and Ventilation Centre) is the IEA information centre on energy efficient ventilation.

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 and consequential health problems.

Designing for optimum ventilation performance is hence a vital part of building design. This task is made especially difficult, however, by the complexities of airflow behavior, climatic influences, occupancy patterns and pollutant emission characteristics.

In recognition of the significant impact of ventilation on energy use, combined with concerns over indoor air quality, the International Energy Agency (IEA) inaugurated the Air Infiltration and Ventilation Centre in 1979 (To be more precise, the AIVC is one of the annexes running under the Energy in Buildings and Communities (EBC) Programme (http://www.iea-ebc.org/) which is one of the Implementing Agreements of the IEA). The AIVC offers industry and research organisations technical support aimed at optimizing ventilation technology. We offer a range of services and facilities, including comprehensive database on literature standards, and ventilation data.

BPA - Building Performance Association


The Building Performance Association 501(c)6 industry association dedicated to advancing the home and building performance industry by ultimately delivering improved energy efficiency, health, safety, and environmental performance of buildings. The Association was created to support home performance contractors, weatherization agencies and training centers, product manufacturers and distributors, program sponsors and implementers, building scientists, and non-profits focused on residential and commercial energy efficiency, including many others who together form the large and diverse network of stakeholders of the building performance industry. State and federal advocacy, education, programs, networking, publications, and community are the means by which the Association aims to support these groups.

The Association was formed through the re-alignment of three organizations, with a special linkage to Building Performance Institute, Inc. The Association now consists of the assets and staff from Efficiency First, Home Energy Magazine, and the Home Performance Coalition, which itself was the result of a merger of Affordable Comfort, Inc. and the National Home Performance Council (NHPC). There is a 17 member board of directors that is made up of representatives of the organizations that created the Association, plus a handful of at-large members. 

BPI - Building Performance Institute


Many of the 130 million homes in this country were constructed before energy and building codes were established. These homes often suffer from performance problems ranging from energy consumption to poor thermal comfort to indoor air quality issues.

In response to these issues, the Building Performance Institute, Inc. (BPI) was founded in 1993. BPI has become the nation's premier standards development and credentialing organization for residential energy auditing and upgrade work. BPI is a 501(c)(3) nonprofit organization.

    Tight Vent


    Reasons behind TightVent Europe

    • Envelope and ductwork airtightness represent a major challenge for the wide-scale implementation of nearly zero-energy buildings
    • There is a growing interest for envelope and ductwork airtightness, because of evidence of energy and IAQ impacts, but:
      • There is a lack of a good understanding of the present status, challenges and experience
      • In less than 10 years from now, probably the majority of new European buildings will have to be assessed in terms of airtightness. It is far from clear now how this can be achieved in a cost effective way and with the support of the major stakeholders
    • If well prepared and carefully implemented, the increased attention to airtightness will result in substantial improvements in the energy efficiency while guaranteeing good indoor climate and it might also be a driver for innovation
    • If the appropriate conditions are not achieved, airtightness might be seen as another burden for the building sector without much added value
    • Through a European collaboration in the context of TightVent, we believe that substantial progress can be achieved
