Brukares påverkan av energianvändning i miljonprogramshus

Sammanfattning: Society's increased environmental awareness is often linked in the construction industry to energy efficiency. A building's energy use includes, among other things, user habits. There’s a lack of objective measurement regarding users' ventilation habits and how they affect energy use. The purpose of this report is to find out how users in exhaust-ventilated apartment building from the 1960’s can influence energy use. The goal is to draw various connections between user habits and energy use. Based on that, then be able to conclude how effectively affect energy use. The method is a literature study and a case study, which is divided into compilation of measurement data from real exhaust-ventilated buildings and energy simulation of different ventilation scenarios in IDA-ICE. People ventilate very differently. Openings that are kept open for the longest time per day are ventilation hatches. Balcony doors are used most frequently. Based on the measurement data, most apartments ended up in the group that airs between 15-30 hours per day (all airing times added up). Total energy use differed by a maximum of 21% between different habits. When compared to the scenario that is most similar to real conditions, energy use could be reduced by 11% if all users in the building were to ventilate the same as those who ventilate the least. If all users in the building ventilate the same as those who ventilate the most, total energy use increases by 8%.
