Analysis of energy requirements versus comfort levels for the integration of phase change materials in buildings

François Maréchal, Martin Vautherot

This paper investigates the importance of the design parameters when looking at possible energy savings and comfort enhancement in a building using Phase Change Materials (PCMs). Computer based simulations are performed using a simulation software for mode ...

CO2 emissions in relation to street-network configuration and city size

Nahid Mohajeri Pour Rayeni

The street-network efficiency of tens of British cities in relation to transport fuel consumption and CO2 emissions are analyzed. The results show a strong linear positive correlation between length entropy and average street length, and a negative correla ...

The sensitivity of predicted energy use to urban geometrical factors in various climates

Marilyne Andersen, Émilie Nault, Parag Rastogi

Urban morphology, including building typology and layout, has a significant influence on the built environment’s access to the sun, which impacts its energy exchange with the environment. This energy exchange is a strong factor in determining the comfort l ...

Defining a braking probability to estimate extreme braking forces on road bridges

Katrin Beyer, André-Gilles Dumont, Marc-Antoine Fénart, Glauco Feltrin

A probabilistic approach is necessary to estimate the magnitude of the braking force that compares in terms of return period with the vertical traffic loads present in bridge design codes. A data set from a Danish Field Operational Test served as support t ...

Refurbishment of Existing Envelopes in Residential Buildings: assessing robust solutions for future climate change

Giorgia Chinazzo

Evaluating the energy consumption of different design solutions during the design process is essential to reach energy targets. Conventionally, building energy performance is evaluated with energy simulations using a single input weather file (design or ty ...

Simple ways to pace trains

Daniel Emery

As long as a train does not conflict with others trains, the energy consumption for traction can be minimized according to its times of departure, arrival, and passing through fixed points. However, when a conflict of itineraries is foreseen, pacing trains ...

Towards a Minergie Standard for tropical climates

Jean-Louis Scartezzini, Franco Vigliotti, Claude-Alain Roulet, Fouad Aabid

The Swiss Minergie®-standard is, by the number of labelled buildings (> 20'000) one of the most successful building energy labels in the world. It is obviously a strong incentive for designing comfortable, low energy buildings. This standard is now valid f ...
