A bottom-up stochastic model to predict building occupants' time-dependent activities

Jean-Louis Scartezzini, Darren Robinson, Frédéric Haldi, Urs Wilke

A bottom-up modelling approach together with a set of calibration methodologies is presented to predict residential building occupants' time-dependent activities, for use in dynamic building simulations. The stochastic model to predict activity chains is c ...

Verification of stochastic models of window opening behaviour for residential buildings

Darren Robinson, Frédéric Haldi

Based on the analyses of data from two distinct measurement campaigns conducted in residential indoor environments in Japan and Switzerland, we identify the specificities of occupants' behaviour with respect to their interactions with windows, including th ...

A personalized measure of thermal comfort for building controls

Nicolas Morel, Frédéric Haldi, David Daum

A personalized measure for thermal comfort has been applied for use in combination with smart controls for building automation. Using data from a field study, we first show the superiority of personalized measures for thermal comfort compared to standard n ...

Modelling occupants’ personal characteristics for thermal comfort prediction

Darren Robinson, Frédéric Haldi

Based on results from a field survey campaign conducted in Switzerand, we show that occupants’ variations in clothing choices, which are relatively unconstrained, are best described by the daily mean outdoor temperature and that major clothing adjustments ...

The impact of occupants’ behaviour on building energy demand

Darren Robinson, Frédéric Haldi

Using extensive field survey data acquired over the past 8 years at the Solar Energy and Building Physics Laboratory at EPFL in Switzerland, comprehensive models of occupants’ presence, opening and closing of windows and the raising and lowering of blinds ...

Taylor & Francis2011

The building sector alone accounts for around half of the energy consumed in Switzerland and most other developed countries, with associated adverse environmental consequences, and there is a great potential for savings in this sector. For this reason, the ...

EPFL2010

Occupants exercise adaptive actions in response to discomforting environmental stimuli in an attempt to restore their comfort. These responses to adaptive actions are either ignored (conventional PMV models) or handled in an aggregated way (adaptive therma ...

Elsevier2010

It is known that thermal perception influences occupants’ adaptive actions in buildings which in turn influence their thermal satisfaction. During recent years there has thus been a growing interest in the development of models which predict occupants ther ...

2010

One of the key sources of uncertainty in building simulation relates to the presence and behaviour of occupants. Fortunately, several academic groups have been working to address this uncertainty, particularly in relation to the use of windows and the corr ...

Using extensive field survey data acquired over the past seven years at the Solar Energy and Building Physics Laboratory at EPFL in Switzerland, models of occupants’ presence, opening and closing of windows and the raising and lowering of blinds have been ...
