TITLE : ENERGY ANALYSIS AND SIMULATION OF THE IBM-BUILDING AT KALVSKINNET
LOCATION : TRONDHEIM, NORWAY
DATE : JUNE/JULY 2017
The summer project of 2017 was done by a bachelor student (M.H.M Sandberg) under supervision and in collaboration with me. It is part of ENERSENSE and contributes to my PhD project. To goal of the project was to analyse the energy consumption of an office building and to look at how energy efficiency can be improved. The outcomes of the project are a reliable simulation model and an analysis of energy saving measures related to the building envelope.
The case study used for this project is an office building, located in the centre of Trondheim, and was built in 1995. The building follows the building code of 1987 and therefore there are significant heat losses through the envelope and due to infiltration. Analysis of the building state and energy consumption showed that the building has a high amount of delivered energy that corresponds with an energy class E. Data regarding the actual delivered energy to the building was provided by Statsbygg. The software that was used to calculate the delivered energy were the simulation tools IDA-ICE and SIMIEN. The average delivered energy from the simulating in SIMIEN is 6% lower than the measured amount of delivered energy, and the IDA-ICE simulation is 3% lower.
Different energy saving measures were simulated to identify the effect on the energy consumption. Since a refurbishment project is about more than simply saving energy, the different measures were evaluated in a bigger perspective. Here, energy savings, cost, thermal comfort and user disturbance were taken into account. The final choice of the measure depends on which of those aspects is valued most.
