BEAVER WORKSHOP

 

Objective

The object of this workshop is to give attendees a basic grounding in the use and application of the computer program BEAVER so that they can on completion of the workshop, perform basic energy simulations in buildings and thereby provide them with the skills to build on this with subsequent practical experience with the program.  The workshop is structured in such a way as to lead attendees progressively through the various aspects of modelling the building and it’s internal loads, the air handling systems and the chillers, boilers and other primary plant.  Attendees are also lead through the results, learning the means by which these can be reviewed and evaluated and the value of the metering capabilities in BEAVER to assist with this.
