Abstract [en]

This thesis investigates the influence of energy visualization on hot water consumption, as well as

builds up the framework for the analysis of electricity consumption, of multi-apartment buildings

in Sweden, . 115 apartments in Nynäshamn have been scheduled to be equipped with feedback visualization,

through the use of television sets, allowing the monitoring of electricity and hot water

consumption on a monthly basis. One year of consumption data prior to this feedback introduction

was acquired for statistical analysis. The results were then displayed and analysed, allowing

for the composition of a generalized conclusion whilst revealing the need for further investigation

and future work.

To achieve this end, clustering was performed on the 115 apartments according to the following

characteristics: Number of tenants per apartment, Area of the apartment, Location of the

apartment, and age of the tenants. Principal Component Analysis was used to select dominant

characteristics, through eliminating highly correlated components, after which trend analysis was

performed on each of the separate clusters revealing a seasonal change model.

Finally, a Multivariate Analysis of Variance utilized on the paired clusters to identify any significant

change, along with post-analysis tests to specify the groups in which significant change was

detected, is presented to be applied in future work.

The preliminary results clearly show that the characteristic data can be grouped into three distinct

clusters of which the consumption trend of hot water consumption is distinct. Moreover the

data reveals a correlation between the apartment’s characteristics and its hot water consumption.

However further monitoring and data collection will be required before any strong trend can be

identified, as well as power analysis will have to be applied to conclude any significant change.

Nonetheless the initial results demonstrate promising signs that ought to be further investigated in

the future.
