Characterization of housings' accessibility

ALCATRA is an application which allows a lessor to characterize the accessibility for the housings, the common areas and the buildings according to a ranking DPE like (Classes A to F) based on five disabilities: seniors, wheelchair, auditory, visual and cognitive.

The key of this application stands in a mechanism allowing experts to build complex dynamic decision trees. I am in charge of the whole development process of the application from the conception to the deployment.

The first release has been deployed in Oct. 15th, 2015. I am now focused on the mobile app development (iOS, Android).


The application is available here:, but only for our customers.

EcoDistricts evaluation campaign

France has been choosen to welcome the next 2015 climat conference.

One objective of this conference will be to show the positive impact of energy efficency wihtin a neighbourhood. In order to achieve this goal, the CSTB has developed a complete methodology allowing the EcoDistrict evaluation. A web application has been developed in order to hide the methodology’s complexity and favor its adoption by local collectivities.

I was in charge of the development team. We have constantly focused our energy on improving the user experience. With agility, we developed the application in parallel to the methodoly definition to help experts work on concrete cases. ‘Keep it simple’ and ‘Don’t repeat yourself’ were our key success factors to be able to refactor everywhere anytime.

Product referencing portal to improve building accessibility for disabled people

Prathic-ERP is a platform which references products that meet the needs of disabled people in institutions welcoming visitors. This site was created on an initiative of the Ministerial Delegation for Accessibility. The Information and Advice Centre for Assistive Technology (CEP-CICAT) with its operation by managing memberships manufacturers and organizing the publishing committee. A complex publishing workflow was set up to ensure the quality of the publications and the relevance of the products.

On top of this complex workflow, we built simple interfaces both for manufacturers and visitors. I was deeply involved in every part of the project, from the product definition to the deployment. I managed the development process with agility and lead the development team. Since 2013, we have released three major versions.

District energy trading optimization

The RESILIENT project aims at designing, developing, installing and assessing the energy and environmental benefits of a new integrated concept of interconnectivity between buildings, DER, grids and other networks at a district level. The RESILIENT approach will combine different innovative technologies including smart ICT components, optimized energy generation and storage technologies, also for RES, integrated to provide real time view of energy demand and supply at a district level and support decision-making processes.

My team at CSTB was in charge of the platform integration. I built a n-tiers architecture based on REST web services to allow communication between the different softwares involved plus a network optimization engine based on genetic algorithms.

Intelligent Neighbourhood Energy Allocation & Supervision

IDEAS “Intelligent Neighbourhood Energy Allocation & Supervision” is a R&D project supported by the European Commission, focused on the development and operation of energy positive neighbourhoods. In addition, IDEAS focuses on the economic and environmental benefits of doing so.

IDEAS develops and validates different tools and business models needed for demonstrating the cost-effective and incremental implementation of an energy positive neighbourhood. The neighbourhood energy management tool enables intelligent energy trading and operation of equipment and buildings along with local energy generation and storage.

My team was in chagre of the development of user interfaces that engage communities and individuals in the operation of Energy Positive Neighbourhoods. I was responsible for the whole development process from conception to deployment.

Friendly Intelligent Energy Management Systems in Residential Buildings

The main objective of this project is the development of an innovative energy management system for existing and new residential buildings(BEMS), which pursues the increase of the efficiency of the energy used and the reduction of the global energy demand of the building, but without penalizing the comfort levels of the users.

I was in charge of the data platform development. The main goal of this platform is to collect save and share all the data exchanged between each module. My principal challenge in this project was to coordinate the development of each module in order to ensure the global integration.

Reduce operating costs and energy consumption in commercial buildings

To reduce operating costs and energy consumption in commercial buildings, to develop the market of services in the field of building, these are the objectives of the project SmartImmo Pole SCS.

The role of CSTB in this project is to define a building reference which provides both general knowledge about building a simple model based on the IFC which can be enriched up by the information produced by sensors and a whole service for handling such data.

I am involved in specification and design, and as a technical advisor for the development team. This application is built over an n-tier architecture, providing first a data model, then a set of Web services allowing other applications to communicate with the repository and building and finally providing both web application and rich client front-end used to interface with users.

Intelligent Use of Buildings' Energy Information

A collaborative project co-funded by the European Commission. Its aim is to develop tools for measuring and analysing building energy profiles based on users’ comfort needs.

My role was to develop the ‘Neighborhood Managment System’. This application was developed to support efficient energy distribution among groups of buildings. The support timely and the optimal energy transfers from a building to another was based on users’ needs and requirements. The optimization was done through the Genetic Algorithms.

Following an Agile methodology, I lead the development team, from the definition of specifications to deliverables.

Semantic Web-based Engineering Platform

SWOP is an EC funded R&D project which I was working on. It aims to provide an Open, Standards-based platform for products and processes optimization.

The team at CSTB is in charge of designing and implementing the Genetic Algorithm Engine. This module handles optimization of complex product configurations (manufacturing, supply chain, construction processes, etc.) via Evolutionary runs, based on Product Data which is expressed using the latest Semantic Web technologies from W3C.

We also lead the design and implementation of an Eclipse plug-in which allows the integrators of the SWOP platform to generate new end-users applications which depend on their concerns and a front-end, a web-based portal that allows end-users to access the features of the SWOP platform.
