On the unification of thermal perception and adaptive actions

Darren Robinson, Frédéric Haldi

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 ...

From the neighbourhood to the city : resource flow modelling for urban sustainability

Jérôme Henri Kämpf, Darren Robinson, Frédéric Haldi, Diane Perez, Adil Rasheed, Urs Wilke, Philippe Leroux

Agreed intergovernmental targets to reduce the emission of greenhouse gases due to predominantly urban anthropogenic activities are becoming increasingly stringent; one might even say ambitious. One crucial strategy in achieving these targets will be to im ...

Explosion of energy demand for air cooling in summer: perspectives and solutions (EEDACS)

Claude-Alain Roulet, Philippe Renaud, Darren Robinson, Frédéric Haldi

The Swiss Federal Office of Energy has published directives in order to limit the increase of electrical energy consumption to a maximum of 5% in 2010 in comparison with 2000. To reach this goal, clear measures have to be taken regarding the installation a ...

Interactions with window openings by office occupants

Darren Robinson, Frédéric Haldi

Based on almost seven years of continuous measurements, we have analysed in detail the influence of occupancy patterns, indoor temperature and outdoor climate parameters (temperature, wind speed and direction, relative humidity and rainfall) on window open ...

On the behaviour and adaptation of office occupants

Darren Robinson, Frédéric Haldi

During the warm summer of 2006 a comprehensive longitudinal field survey of the adaptive actions of occupants, their thermal satisfaction and the coincident environmental conditions was conducted in eight Swiss office buildings. We have applied logistic re ...

Towards comprehensive simulation and optimisation for more sustainable urban design

André Gabriel Kostro, Darren Robinson, Frédéric Haldi

In this paper we discuss progress that has been made in modelling of urban resource flows to support urban designers to optimise the sustainability of their design and planning proposals, In particular we consider models of urban energy demand and more gen ...

Towards comprehensive simulation and optimisation for more sustainable urban design

Jérôme Henri Kämpf, André Gabriel Kostro, Darren Robinson, Frédéric Haldi

In this paper we discuss progress that has been made in modelling of urban resource flows to support urban designers to optimise the sustainability of their design and planning proposals. In particular we consider models of (i) resource availability, (ii)e ...

An integrated adaptive model for overheating risk prediction

Darren Robinson, Frédéric Haldi

Based on the results from a field survey campaign, this article describes three new developments which have been integrated to provide a comprehensive basis for the evaluation of overheating risk in offices. Firstly, a set of logistic regression equations ...

Model to predict overheating risk based on an electrical capacitor analogy

Darren Robinson, Frédéric Haldi

It is important for building designers to be able to judge if a space is likely to overheat, whether to determine if HVAC plant is required or to design this out by passive means. To this end several overheating risk criteria have recently been published. ...

An adaptive model of overheating risk

Darren Robinson, Frédéric Haldi

Based on analogy between the charging and discharging of humans' tolerance to overheating stimuli and that of charge in an electrical capacitor, this paper proposes a simple mathematical model for predicting overheating risk given a set of measured / simul ...
