A Global Building Occupant Behavior Database

Andrew James Sonta, Zhe Wang, Sanjay Kumar, Xin Zhou, Yanchen Liu

This paper introduces a database of 34 field-measured building occupant behavior datasets collected from 15 countries and 39 institutions across 10 climatic zones covering various building types in both commercial and residential sectors. This is a compreh ...

Investigating the impact of different natural ventilation modes on indoor air quality and overheating

The introduction of fresh air by means of natural ventilation is a technique that can improve indoor environmental quality in an energy-efficient manner. Nevertheless, recent studies revealed that the window opening during the summer months, even though it ...

Reaching Thermal Comfort Zone Limits for Resilient Building Operation: A Winter Case Study for Offices

Dolaana Khovalyg, Verena Marie Barthelmes, Arnab Chatterjee

A specific range of acceptable indoor thermal conditions is stipulated by building performance standards to assure minimum dissatisfaction of occupants. Thus, the operation of buildings in practice tends to follow a cautious approach by setting the indoor ...

Reinforcement Learning for proactive operation of residential energy systems by learning stochastic occupant behavior and fluctuating solar energy: Balancing comfort, hygiene and energy use

François Maréchal, Dolaana Khovalyg, Amirreza Heidari

When it comes to residential buildings, there are several stochastic parameters, such as renewable energy production, outdoor air conditions, and occupants’ behavior, that are hard to model and predict accurately, with some being unique in each specific bu ...

Impact of the ventilated air-space behind traditional (passive) and BIPV (active) façades on the thermo-hydrodynamic performance of the building wall structures

Mohammad Rahiminejad

For many decades, ventilated cavities in wall assemblies of buildings have been essential for creating moisture-resilient constructions by allowing airflow within the air gap to promote drying. In addition to that, the airflow in the cavity can contribute ...

Interindividual variability of human thermoregulation: Toward personalized ergonomics of the indoor thermal environment

Dolaana Khovalyg

Objective The study was undertaken to show the magnitude of interindividual differences in energy expenditure (i.e., heat production) under normal living conditions with the aim of providing physiological evidence to support the advancement of a personaliz ...

Reinforcement Learning for the occupant-centric operation of building energy systems: Theoretical and experimental investigations

Amirreza Heidari

Occupant behavior, defined as the presence and energy-related actions of occupants, is today known as a key driver of building energy use. Closing the gap between what is provided by building energy systems and what is actually needed by occupants requires ...

Occupant satisfaction with indoor environmental quality, sick building syndrome (SBS) symptoms and self-reported productivity before and after relocation into WELL-certified office buildings

Dusan Licina, Serra Yildirim

Recent green building certification programs have put a strong emphasis on occupant health and well-being. For recently emerged WELL certification, we lack evidence about its effectiveness in relation to occupant satisfaction, productivity and health. Here ...

A performance-driven simulation workflow for PV integration into the design process: application on an innovative building project in Switzerland

Sergi Aguacil Moreno

In the construction sector, the integration of active elements functioning both as building envelope material and on-site electricity generator is identified as a key measure to achieve the 2050 targets and carbon neutrality (Aguacil Moreno, 2019; Aguacil ...

Effectiveness of passive climate change adaptation measures in Switzerland: A climate-based analysis on natural ventilation and overheating risks reduction in dwellings

Sergi Aguacil Moreno, Daniel Zepeda Rivas

Building energy codes have been implemented in Switzerland as well as across the world to reduce building energy consumption, however, due to the progressive effect of climate change phenomena and the precipitate change in occupancy patterns due to the glo ...
