Article
Full-text available
The aim of this work is to propose a tool to help the design of district heating networks (DHN). The configuration (network layout and production technologies) and the design (mass flow rate, temperature, heat capacity to install and area of the heat exchanger) are optimized simultaneously.
Article
The aim of this work is to propose a tool for the design assistance of District Heating Network (DHN). Two goals of DHN optimization are handled simultaneously: the optimization of the configuration and its design. The optimization objective is to minimize the global cost of the DHN over 30 years. It includes both operating costs (heating and pumpi...

Full-text available
The aim of this work is to propose a tool for the design assistance of District Heating Network (DHN) at the beginning of an urban project, as well as for an extension of an existing network. Two goals of DHN optimization are handling at the same time: the optimization of the configuration (network layout, choice between the different production te...
Article
Full-text available
The proposed methodology relies on the modelling capabilities of the thermo-radiative model SOLENE to simulate the heat and radiation energy exchanges between an actual urban district and the atmosphere. It is based on the comparison of the simulated upward infrared and sensible heat flux diurnal cycles that may be measured by elevated sensors abov...
Conference Paper
To save energy, to reduce greenhouse gas emissions and to increase the occupants comfort, the French Government launched a huge plan to make low, passive and positive energy buildings become a standard and to renovate existing buildings. This article presents a global energy renovation program applied to the Malartic district, close to Bordeaux in...
Data
Given the difficulty of the consideration and assessment of buffer zones of buildings such as greenhouses, double skin façades and atriums, the tool TOPAZ has been developed. The tool is designed to provide information to assist in the design phase of projects including such a buffer zone. It is based on a fast and easy to use method that leads to...
Article
Full-text available
Surface brightness temperatures modeled using the SOLENE model with effective model parameters derived from Part 1 Hénon et al. (2012) are compared to temperatures obtained from an airborne thermal camera at the facet and pixel scales. The measurements were made during both summer and winter intense observation periods over the center of Toulouse,...
Article
Full-text available
A methodology is proposed to analyze the radiative and thermal exchanges between a small urban neighborhood and the atmosphere based on the use of the thermoradiative model SOLENE and radiometric measurements to optimize the effective values of its constant parameters. Applied to the center of Toulouse, France, the optimization data are building su...
Article
Measurements of thermal infrared (TIR) directional anisotropy (difference between off-nadir and nadir brightness temperatures) performed over the city of Toulouse using a method based on the use of 2 airborne TIR cameras are presented. Results from 3 flights at different times during a summer day (July 15th 2004) and from 1 flight in winter (Februa...
Conference Paper
Due to the morphological complexity of the urban canopy and to the variability in thermal properties of the building materials, the heterogeneity of the surface temperatures generates a strong directional anisotropy of thermal infrared remote sensing signal. Thermal infrared (TIR) data obtained with an airborne FLIR camera over Toulouse (France) ci...
Thesis
Full-text available
In the case of an urban fragment the presence of horizontal, vertical, oblique, and very heterogeneous surface elements yields complex definitions of the surface and its associated temperatures. The objective is to establish parametric relationships between the sensible heat and infrared fluxes, which are both related to the surface temperature. Ae...

• Develop a method to assist in the design of a distribution network for the supply of heating energy to a group of buildings (district scale). The type of network considered can integrate several sources of energy, several types of consumers (tertiary building, dwelling). • Adapt these methods to the technical and decision-making context specific to the construction sector and energy services for buildings. • Test and validate the methods and models by experimental data obtained in real conditions.
Project
Built to Specifications (Built2Spec) is a Horizon 2020 EU-funded project involving 20 European partners that seeks to reduce the gap between a building’s designed and as-built energy performance. To do this, the project will put a new set of breakthrough technological advances for self-inspection checks and quality assurance measures into the hands of construction professionals. This collection of smart tools will help building stakeholders at all levels in meeting EU energy efficiency targets, new build standards and related policy goals. http://built2spec-project.eu/aboutus/
