A survey among relevant consultants and contractors shows the need for better knowledge and more systematic information in order to make decisions regarding the selection of system for energy supply of ZEBs (Zero Emission Buildings). The ZEB centre aims to develop a computerbased tool for this purpose that will include both a calculation tool and an information database. This assignment will be part of this development.

The main objective of this work is to evaluate the cost optimality of different energy systems for a ZEB using the European cost optimal methodology introduced in the context of the EPBD (Energy Performance of Buildings). Both modelling and evaluation of energy performance of the building and its energy systems and calculation of costs are part of this assignment.

Modelling of a typical new residential building will be performed using the dynamic simulation tool IDA-ICE; while the calculation of costs will be based on the data previously collected by the student during his project assignment and summer job. The choice of the type of building to model will be made in connection with the pilot projects of the ZEB centre.

This assignment is closely related to The Research Centre on Zero Emission Building at NTNU and SINTEF (FME ZEB) that has the vision to eliminate the greenhouse gas emissions caused by buildings. The main objective of FME ZEB is to develop competitive products and solutions for existing and new buildings that will lead to market penetration of buildings that have zero emissions of greenhouse gases related to their production, operation and demolition.
