Visualizing street orientation and solar radiation in relation to complex topography

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Nahid Mohajeri Pour Rayeni

Street networks can be visualized in various ways depending on the purpose. Here we introduce (in the present context) a new technique for visualizing the orientation of street networks in relation to complex topography. The technique is tested on the city ...

Ground temperature modelling: The case study of Rue des Maraîchers in Geneva

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Govinda Upadhyay

This paper presents a methodology to approximate the urban heat island effect by using a PostgreSQL database and CitySim software, a simulation tool to evaluate urban energy flows. A ground temperature model has been developed for shallow depths (until 4m) ...

Design in the desert. A bioclimatic project with urban energy modelling

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Silvia Coccolo

The increase of the world's population leads to an urgent need of radical measures to diminish the energy footprint of humanity. This study considers the realisation of an optimal Masterplan in energy terms for the new EPFL Research Centre in Ras A1 Khaima ...

Comparison of objective and subjective visual comfort and associations with non-visual functions in young subjects

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Friedrich Linhart, Apiparn Borisuit, Mirjam Münch

Visual comfort is a key element at work places and at home. Besides task illuminance and color rendering it is the indoor light distribution, which strongly impacts visual comfort. We aimed to show possible relations between subjective and objective visual ...

Ray-tracing simulation of complex fenestration systems based on digitally processed BTDF data

Jean-Louis Scartezzini, Jérôme Henri Kämpf

The implementation of Complex Fenestration Systems (CFS) in the day-to-day life by practitioners, such as lighting designers, architects and façade makers is not an easy task. However, computer design tools can reinforce their usage through the determinati ...

CITYSIM simulation: the case study of Alt-Wiedikon, a neighbourhood of Zürich City

Jérôme Henri Kämpf, Diane Perez, Darren Robinson, Urs Wilke, Maria Papadopoulou

As research in building energy demand simulation is reaching maturity, there is now a growing interest in the evaluation of the energy need of larger and/or pre-existing urban areas [1, 2, 3], to evaluate the energy performance associated with alternative ...

Optimisation of building form for solar energy utilisation using constrained evolutionary algorithms

Jérôme Henri Kämpf, Darren Robinson

In this paper we describe a new methodology for optimising building and urban geometric forms for the utilisation of solar irradiation, whether by passive or active means. For this we use a new evolutionary algorithm(a hybrid CMA-ES/HDE algorithm) to searc ...

Ray tracing study for non-imaging daylight collectors

Raphaël Compagnon, Jean-Louis Scartezzini, Jérôme Henri Kämpf, Friedrich Linhart, Stephen Wittkopf, Lars Oliver Grobe

This paper presents a novel method to study how well non-imaging daylight collectors pipe diffuse daylight into long horizontal funnels for illuminating deep buildings. Forward ray tracing is used to derive luminous intensity distributions curves (LIDC) of ...

A comparison of global optimisation algorithms with standard benchmark functions and real-world applications using EnergyPlus

Jérôme Henri Kämpf, Darren Robinson

There is an increasing interest in the use of computer algorithms to identify combinations of parameters which optimise the energy performance of buildings. For such problems, the objective function can be multi-modal and needs to be approximated numerical ...

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

Jérôme Henri Kämpf, Diane Perez, Darren Robinson, Adil Rasheed, Frédéric Haldi, 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 ...

On the modelling and optimisation of urban energy fluxes

Jérôme Henri Kämpf

Around 3/4 of global resources are currently consumed in urban settlements, with corresponding adverse environmental consequences. According to population forecasts this situation will worsen in the coming years. It is therefore imperative that we understa ...

A hybrid CMA-ES and HDE optimisation algorithm with application to solar energy potential

Jérôme Henri Kämpf, Darren Robinson

This paper describes the results of initial experiments to apply computational algorithms to explore a large parameter space containing many variables in the search for an optimal solution for the sustainable design of an urban development using a potentia ...

Optimisation of buildings solar irradiation availability

Marylène Montavon, Raffaele Bolliger, Jérôme Henri Kämpf, Josep Bunyesc Palacín, Darren Robinson

In order to improve the sustainability of new and existing urban settlements it is desirable to maximise the utilisation of the solar energy incident on the building envelope, whether by passive or active means. To this end we have coupled a multi-objectiv ...

Towards comprehensive simulation and optimisation for more sustainable urban design

André Gabriel Kostro, Jérôme Henri Kämpf, 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 ...

Optimisation de la forme urbaine pour une meilleure utilisation de l'énergie solaire

Jérôme Henri Kämpf, Darren Robinson

Ce travail prend son inspiration d’un projet qui a pour objectifs la prédiction et l’optimisation de la performance environnementale de districts urbains. L’optimisation passe par la mise en oeuvre d’Algorithmes Evolutionnaires (EA) dont le but est de trou ...

Optimisation of Buildings Daylight Availability

Marylène Montavon, Jérôme Henri Kämpf, Darren Robinson

Many researchers have the goal of improving buildings daylight availability in order to decrease the HVAC energy intake. Indeed by achieving/identifying sustainable urban forms and their design concepts, the benefits of the solar radiation can be of threef ...

Towards an evolutionary model of city sustainability

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Darren Robinson, Adil Rasheed, Nataliya Filchakova

In part stimulated by the computer game industry, reasonable progress has been made in the dynamic modelling of urban growth and land use change. However, sustainability considerations in this work remain to be addressed. Yet the environmental impact of ci ...
