A Multi-sensor Office-building Database for Experimental Validation and Advanced Control Algorithm Development

Data from multiple sensors and actuators has been recorded from December 2001 to March 2008 at the LESO-PB building of the EPFL campus, using the EIB/KNX bus standard. Sensors and actuators provided data on room temperature, presence, lighting level, windo ...

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 ...

Identifying important state variables for a blind controller

Nicolas Morel, David Daum

In literature many different blind controller have been proposed and it has been shown in most cases, that they can provide energy savings and better comfort. In the early approaches they where based only on one state variable, but over time more variables ...

Assessing the total energy impact of manual and optimized blind control in combination with different lighting schedules in a building simulation environment

Nicolas Morel, David Daum

In this work, we investigated the interplay and the influence of lighting and blind control models on the heating, cooling, and lighting energy loads of an office room. By including different stochastic models for occupancy and appliances, we built a compl ...

Coupling Thermal Simulation and Multi-Objective Coupling Thermal Simulation and Multi-Objective - Optimization for Blind Controller Design

Nicolas Morel, David Daum

In this paper we present results of computational experiments where multi-objective algorithms were used to tune a controller for blind movements in a room of the LESO experimental building. The blind controller which is based on fuzzy logic was optimized ...

A generalised stochastic model for the simulation of occupant presence

Jean-Louis Scartezzini, Jessen Page, Darren Robinson, Nicolas Morel

This paper describes an algorithm for the simulation of occupant presence, to be later used as an input for future occupant behaviour models within building simulation tools. By considering occupant presence as an inhomogeneous Markov chain interrupted by ...

Bayesian estimation of visual discomfort

Nicolas Morel

A method is proposed to estimate objectively occupants' visual discomfort in small office rooms as a function of the illuminance at one or more locations. Expressed as a visual discomfort probability, it is based on an analysis of the past history of the u ...

SUNtool - A new modelling paradigm for simulating and optimising urban sustainability

Jessen Page, Darren Robinson, Nicolas Morel

This paper describes the development and application of a new unique tool to support designers to optimise the sustainability of urban neighbourhoods (SUNtool). In this the paper introduces (i) the software architecture, (ii) the integrated solver and rela ...

On-site performance of electrochromic glazings coupled to an anidolic daylighting system

Jean-Louis Scartezzini, Jessen Page, Nicolas Morel

This work takes benefit from two advanced building technologies through the integration of an anidolic daylighting system and an electro-chromic glazing in a building facade for achieving an optimal control of the daylight flux entering in an office room. ...
