Abstract [en]

Knivsta municipality is planning a new climate-friendly and environmentally sustainable

district called Nydal. The vision is to create a residential area that is minimally

dependent on outside sources of electricity. The aim of this research is to evaluate

the efficiency and electricity demand of a residential house in Knivsta.

A model for the power demand of an apartment house has been constructed, using

data for the electricity consumption of one household from Kiruna during a week in

April. Data from the Swedish Energy Agency has been used to identify the distribution

of electricity for the different loads. This study has focused on the electricity

consumption of a family that consist of two adults and one child and their use of

home appliances. A comparison between standard appliances and energy efficiency

appliances has been made to find out how much the power and their load peaks can

be reduced.

The total amount of electricity consumption for the residential building’s households

is about 93 MWh during a year. By selecting energy efficient appliances in the

apartments the total household electricity consumption of the residential building can

be reduced by about 55 MWh, which is almost a 60 % reduction per year. The

residential buildings load peaks can be reduced. This can be achieved by installing

energy efficient products by using Top Ten’s list over the most energy saving

household appliances available on the market. Installing LED lamps and HWC driven

products also reduces the power demand significantly. By installing HWC driven

products in the common washhouse, the residential electricity can be reduced by 29

%.

A more environment-friendly lifestyle affects the electric load. The power demand can

decrease if buying less power demanding products, but also by using the power

demanding products in a more energy efficient way. Knivsta municipality is able to

help the tenants in Nydal to increase their knowledge. By increasing the individuals’

knowledge about power demand and energy saving, it is possible to influence

individuals’ behavior and with that reduce the electric load.
