Abstract

This report presents the main findings of the activity 4.4 “Reference procedures for obtaining occupancy profiles in residential building” belonging to IEA EBC Annex 66 Subtask A. The activity was conducted with the aim of providing methods to describe occupancy in residential buildings and technical approaches to define occupancy profiles for energy simulations. Occupancy data can be classified into four levels: presence status (“occupied” and “unoccupied”), number of occupants, place in the space and activity. Occupants’ profiles can be defined by considering how people occupy the building, how they use the systems (heating, cooling, etc.), and how they interact with devices including windows, blinds, lights, appliances, etc. Occupancy profiles may differ significantly from each other and affect the energy performance of buildings. Their determination is essential as they are necessary inputs to energy building simulation. Based on these considerations, the report is focused on:
1. Investigating the procedures used to obtain occupancy profiles and their limitations;
2. Identifying the problems of data collection methods;
3. Characterizing different types of variables necessary to define representative occupancy profiles.
To achieve the aims above, the following steps were done:
1. Completing a literature review by considering different residential context and doing a classification (by continent, methodology, type of statistical analysis and other);
2. Providing information about methodologies for data collection and processing;
3. Define the variables to be considered in surveys to get occupancy profiles.
