IBPSA has four categories of membership:

Information concerning elections can be found here.

Regional Affiliate Membership

The regional affiliate organizations form the primary membership of IBPSA and act as the focus for member activity. The affiliates are financially and administratively independent of the IBPSA central organization, which gives them the power to organize their own programme of activity. There are currently 24 regional affiliate members spanning 5 continents.

Regional affiliate membership is subject to approval of the IBPSA board of directors. Further information on Affiliate membership can be obtained from the Affiliate Development Officer (see Board of Directors list).

Individual Members

Individual membership of IBPSA is achieved through joining a regional affiliate organization. All individual members of the IBPSA regional affiliates are automatically members of the IBPSA central organization.

In addition to being able to participate in regional activities, IBPSA individual members benefit from a reduction in the biannual conference fees, and members are entitled to subscribe to a print version of IBPSA’s research Journal, “The Journal of Building Performance Simulation” (JBPS). From 2017 the special subscription rate to JBPS is USD 54/£42/EUR 47. Members should contact +44 (0)20 7017 5543 or to subscribe. (Please note that subscriptions purchased at the personal rate are strictly for personal, non-commercial use only.)
