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 URBAN ENERGY DEMAND

Darren Robinson, Frédéric Haldi

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 ...

Adaptive actions on shading devices in response to local visual stimuli

Darren Robinson, Frédéric Haldi

Based on 6 years of continuous measurements, we have analysed in detail the occupancy, thermal and visual parameters influencing actions on shading devices in order to derive an accurate model for the prediction of their usage in office buildings. This art ...

Towards a Unified Model of Occupants' Behaviour and Comfort for Building Energy Simulation

Frédéric Haldi

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 ...

Results from the monitoring of indoor environment and occupant perceived productivity in office buildings

Darren Robinson, Frédéric Haldi

Based on almost 18 months of continuous direct measurements coupled with an electronic questionnaire, we have analysed the influence of indoor temperature and illuminance, outdoor climate parameters, thermal and visual sensation, clothing and season on the ...

A PARTIAL DOUBLE BLIND EVALUATION OF A COMPREHENSIVE WINDOW OPENING MODEL

Darren Robinson, Frédéric Haldi

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 ...
