Courses in IDA Indoor Climate and Energy, November 2012

EQUA is offering hands-on courses in IDA Indoor Climate and Energy (IDA ICE). A link to detailed course information and registration can be found below.

1. Basic course We introduce you to the basic functionalities of IDA ICE and the process of creating a simulation model. Lectures are interspersed with computer exercises. Target group: beginners Date: Wednesday, November 21, 2012

2. Intermediate course Having created a few models in IDA ICE and gained some experience, we show you how to make even more use of the software. We look at various models and functions to enhance the understanding and productivity of the software, such as systematic handling of input data, connecting your own models, ventilated facades and sun protections in combination with sun protection glass, methodology to build geometries, and import of building geometries and ground profiles using SketchUp and Google Earth. Target group: user passed beginners stage Date: Thursday-Friday, November 22-23, 2012

3. Practical Energy Simulation The course is intended for those who work with energy simulation in construction projects and who want to learn more about how to make realistic energy simulations. Target group: user passed beginners stage Date: Monday-Tuesday, November 26-27, 2012

The courses are held in Swedish, between 9 AM to 5 PM at EQUA's office, Råsundavägen 100, Solna (Stockholm). Last date for registration: Friday, November 16, 2012 For more information and registration, please click here

Open lectures During the fall the Royal Institute of Technology (KTH) in Stockholm gives the courses "Energy and indoor climate modeling in buildings" and "Sustainable buildings - design, construction and operations" (both at Master’s degree level). As a part of these courses EQUA will hold lectures and hands-on exercises in IDA ICE. As a customer and user of IDA ICE you will now have the opportunity to participate in a selection of these lectures at no cost.

Windows - the Achilles heel of the building envelope The window expert at ÅF, Anna Werner, talks about heat balance, day light and sun protection. Speaker: Anna Werner, ÅF Date: Wednesday, October 31, 9-12 AM Location: EQUA

Indoor climate We go through some requirements for indoor climate in various quality systems and how to use IDA ICE to verify that the requirements are fulfilled. Speaker: Jörgen Eriksson, EQUA Date: Friday, November 02, 9-12 AM Location: EQUA

Simulation of indoor climate with CFD Speaker: Mats Finnson, Sweco Date: Friday, November 16, 9-12 AM Location: to be announced later

The lectures are held in Swedish. To register please send an e-mail to no later than the day before the current lecture. Note: The number of places are limited.

Nordic PhD Seminar on Net Zero Energy Building Strategies, Systems and Technologies in collaboration with IBPSA-Nordic

Place: Aalborg University, Sohngaardsholmsvej 57, 9000 Aalborg, Denmark Time: 8-9 December 2011.

Organised by Per Kvols Heiselberg (


Research and development activities related to the development of cost-effective net zero energy buildings have a high priority in all  Nordic countries and have lead to the initiation of a number of similar research activities in the last few years in all the Nordic countries. The purpose of the workshop is to gather PhD students from all the Nordic Countries to exchange information and to establish cross country collaboration in order to coordinate research work and to exploit synergies. Research in net zero energy buildings is naturally multi-disciplinary and covers a wide range of research topics. This first workshop will cover the following topics:

  • Cost effective solutions for NetZEB buildings. Cover research on LCC of NetZEB building concepts and system solutions as well as research on total system energy optimization, …
  • Refurbishment of the Existing Building Stock. Covers research on barriers and drivers as well as strategies and technical solutions for refurbishment, ….
  • NetZEB Building Energy Efficiency. Cover research on energy efficient building envelope systems, glazed facades and windows, thermal mass activation, highly efficient building services and building performance assessment…
  • Optimal building integrated renewable energy systems. Cover research on building integrated renewable energy systems and highly efficient building services, on system design and optimization and on matching of energy demand and production…
  • Indoor Environmental Quality. Covers research on indoor environment in NetZEB Buildings, user related aspects of NetZEB building operation,…

IBPSA-Nordic made its initiation meeting in Aalto University, Espoo- Finland on 26.8.2011. Twelve delegates from four countries Denmark, Finland, Norway and Sweden attended the meeting. During the meeting, elections for the Board posts took place for the first two-years round. The names of the Board post and members can be found from the PEOPLE page. The by-laws of the organisation can be found in the ABOUT page.
