Digital tools for monitoring the environmental performance of buildings

Real estate players who properly communicate the performance of their building stock put in place the appropriate means to recover and analyze the relevant data to monitor their environmental performance.  In a data-driven context CSR reporting must also be based on factual and quantified indicators.

An smart building aims to meet these challenges of obtaining, analyzing, optimising data before deployment of actions.  Indeed, a technological breakthrough is currently taking place with under the umbrella of the IoT (‘Internet of Things’) and the development of associated technologies, for example: the use of BIM throughout the design, construction and operations of a building, deployment of autonomous low energy sensors allowing the feedback of building data, energy monitoring, failure alert system and automate several systems

In this edition there are three concrete innovations that make it possible to integrate and monitor precise CSR indicators of buildings.

Controlling indoor air quality – Nanosense’s SmartQAI solution

Air pollution is at the top of Parisians’ environmental concerns. Air quality, both indoor and outdoor, is a major issue in terms of health. In a 2016 study, the French Public Health Agency estimates that the number of deaths in France due to fine particles is at least 48,000 persons per year.

Thus, it is necessary to improve the indoor air quality of a building understanding they are exposed to various sources of internal pollution (CO2 released by the occupants, VOCs emitted by paints, carpets and interior fittings products, or fine particles generated by computer equipment, particularly printers). These exposure influences both health and productivity; studies indicate that a concentration of 1000 ppm CO2 corresponds to a reduction in cognitive functions of more than 23%.

The SmartQAI solution developed by NanoSense is one of the 5 winning projects in the experimental program on air quality led by the City of Paris and aims to improve the quality of indoor air in buildings while optimizing the energy consumption required for their ventilation. Nanosense is a manufacturer of indoor air quality probes integrating ventilation controls for multi-pollutant threshold exceedances: CO2, fine particles, humidity, temperature.

The NanoSense system aims to integrate indoor air quality into the building’s technical ecosystem, using standardized communication processes and protocols to optimize its operation. For example, light-presence sensors can now be used to influence indoor air renewal rates by taking into account room occupancy. Healthy air and energy savings are the key.

Optimizing the energy performance of buildings – the example of “Le Hive”

“Le Hive”, Schneider Electric’s headquarters in Rueil-Malmaison, is the first building in the world to obtain ISO 50 001 certification for energy management systems in June 2011. ISO 50 001 sets out a framework of requirements for companies who want to implement an energy management system, including performance objectives based on the analysis of building data to better understand energy use and consumption. To achieve this, the role of the Building Energy Manager is to understand and analyze this data in order to optimize energy consumption while maximizing the comfort of the occupants. The Energy Manager must also raise awareness, convince and involve users in energy management, the use of available technologies and the adoption of more sober behavior.

In order to make the building as economical as possible, “Le Hive” is composed of a network of 186 meters, more than 5,000 measurement sensors connected to a complete BMS and a building data analysis platform. The sensors collect the data (energy by use, activity and sector, occupancy rate, temperature, weather, dissatisfaction, etc.) which are then analysed using Schneider’s Energy Operation operating software.

In this case the integration of the ISO 50 001 into a buildings performance monitor strategy is key to communicate results.

R2S Label – For connected and communicating buildings

The R2S label, Ready2Services, awarded by Certivéa (a French certification organization) and launched in June 2018 through 12 pilot operations, was developed in partnership with the Smart Buildings Alliance for Smart Cities, the HQE-GBC Alliance, and several building stakeholders (project owners, design offices, manufacturers, etc.).

The label concerns non-residential buildings (offices, shops, hotels, sports facilities, etc.), new or existing, under construction/renovation or in operation. It also aims to guide building stakeholders in setting up concrete steps to take into account the challenges of digital technology, and make the building a platform of services that can provide comfort, environmental performance and safety.

The objective is to make the building inclusive, on the one handby associating its occupants, and, on the other hand, by integrating into a district or a city.

This aim for connectivity, makes the R2S label, an interesting tool to position a as an essential brick of the digital and sustainable city of tomorrow.

As the building becomes a connected object to the service of its operators, and users, it must also be able to measure, analyze and “upgrade” its functioning. Moreover, all the data obtained on the buildings is used to feed and guide the company’s environmental policy in relation to its real estate portfolio.

However, in a world that must move towards greater simplicity, it is important not to consider technology as the miracle cure for all ills, but to ask some questions about the solutions deployed in the building, such as: what is the lifespan of electronic components, what are the resources needed to produce the systems? are the solutions scalable and adaptable? Are there compatibility problems within the systems?

The objective is to make the digital transition compatible with a successful ecological transition.

Note:  – The Internet of Things or IoT is the materialization of the Internet in the real world. It concerns all objects, cars, buildings and other elements connected to a physical Internet network by a computer chip, sensor, network connectivity allowing them to communicate with each other, collect and exchange data. Thanks to IoT, these materials can be controlled and monitored remotely through an existing network infrastructure. [Source:]
