Excerpt from one conference report: “Occupants were generally satisfied with their new houses, but were most dissatisfied with the thermal conditions. A majority (68%) specified that they experienced too warm during summer. This was the most prevalent complaint, and in agreement with physical measurements. During winter the occupants were also most dissatisfied with thermal conditions as 27% of respondents experienced too cold, and 25% found that the temperature varied too much. Additionally, there were a series of problems with the technical installations and their use was difficult. The energy use was higher than expected.”
If you haven’t had a chance to read the study, it concluded with a series of recommendations to increase occupant satisfaction in low energy houses:
• Avoid uncomfortably high temperatures during summer with external solar shading, consider the size of the windows facing towards the sun and make effective use of natural ventilation possible.
• Develop more robust and easy-to use technical installations enabling occupants to control the indoor climate and energy consumption as intended in their new relatively technically advanced house, e.g. by a single user-friendly user interface that can communicate with all relevant technical installations.
• Ensure that occupants can use their house as intended by technical installations being fully operational from day one.
• Communicate about the energy consumption so that occupants get realistic expectations according to their family situation and behavior.
Ok…so for our long time readers do you recognize any of these comments?
We'll be discussing more on these topics in our three day integrated design program.
