The IBPSA News Volume 23 No 1 is now available at

Features include: Update about Building Simulation 2013 (including program and keynote speeches); an introduction to Stack exchange – a proposal for a supplement to the BLDG-SIM list and an interview with its creators; part 2 of the feature article and interview with Hugo Hens, continuing the discussion about the limitations of Heat, Air and Moisture (HAM) modelling and problems encountered in practice; and many other recent and future activities of IBPSA Regional Affiliates.

The success of the Building Simulation conference held late in 2011 proved there was a demand for more information about the field. With this in mind, AIRAH, supported by IBPSA (The International Building Performance Simulation Association), is hosting the AIRAH Building Simulation Workshop in Melbourne on April 18.

IBPSA-USA would like to announce recent improvements to the BEMBook Wiki – – and would like to invite the energy modeling community to participate in this online resource. You are invited to both explore and contribute content. It is simple to edit an existing page or to create a new page.

Please check it out.

We invite you to contribute your knowledge to the wiki.

Here are a few highlights about the new, improved wiki:

  • A new menu bar and table of contents greatly improves site navigation
  • Building energy modeling training presentations are available for download
  • There is a growing body of content – though we still have a long way to go! Here are examples of a few recent contributions:
We hope that BEMBook will become the premier resource for the energy modeling community around the world – and with your help, it will!

Keep in mind that this wiki is software-independent and intended to provide general guidance regarding energy modeling concepts and practices. Promotion of specific software is not allowed! (and will be removed) BEMBooK is an acronym for Building Energy Modeling Body Of Knowledge, and as the name indicates, its purpose is to broaden the body of knowledge available to the energy modeling community in a way that helps everyone.

See this page for quick guidance on getting started:
