Measuring air quality and temperature with smart buildings

Measuring air quality and temperature with smart buildings

The temperature and air quality of buildings are essential to the comfort and well-being of occupants. The Energisme platform includes a specific module to monitor these data continuously in order to improve the quality of life in the building but also to meet the challenges of energy performance.

Why should we measure the air quality of a building?

Indoor air quality affects the well-being of the occupants or users of a building. Good air quality promotes concentration and helps reduce absenteeism in schools. 

Conversely, poor air quality can be a source of discomfort (headaches, fatigue) and even respiratory pathologies. In a professional context, air quality also affects the productivity of employees.

In France, indoor air is both a health and economic issue that is subject to specific regulations. The Ministries of Environment and Health have established an action plan to improve air quality in enclosed spaces. 

This plan came into effect on January 1, 2018 in places where children under 6 years of age are accommodated (day care centers, nursery schools,…) and elementary schools. From January 1, 2020, it extends to colleges, high schools and leisure facilities.

It includes:

  • Obligations to monitor air quality in establishments open to the public, in particular schools and nurseries.
  • The publication of standards for indoor air quality

How do you know if the air inside a building is of good quality?

The smart building facilitates the collection of data on the air quality of buildings. Indeed, the installation of IoT (Internet of Things) sensors in the smart building makes it possible to collect data on:

The temperature in the different spaces of the building

The control of the tightness of the walls

The rate of C02 in the spaces

The speed of the air

Energisme solution

In a connected building approach, data provided by the Internet of Things can be crossed with :

  • equipment data, including HVAC (heating, ventilation, air conditioning)
  • external data such as outside temperature, weather or atmospheric conditions

Centralized in a unique platform like Energisme, these data are then processed and analyzed. Initially, it is easy to compare them to the reference values issued by the government. The solution also allows to set up alerts when critical thresholds are approached.

In addition, the data analysis facilitates the detection of air quality degradation factors. This overview allows operators to identify areas for improvement and undertake the necessary energy retrofits.

Why and how to measure the temperature of a building?

A crucial issue

Measuring the temperature of the building is also an issue for the operators. Indeed, a continuous or real time monitoring of temperatures is essential to:

  • improve comfort in housing
  • improve the energy performance of the sites and, in particular, the heating systems

Measurement of temperature and temperature variations

In an intelligent building, the installation of connected sensors allows us to measure temperature and temperature variations in detail. These data are centralized in the Energisme platform, cross-referenced with other data (heating system data, outside temperature, humidity level, …) and analyzed thanks to the solution’s artificial intelligence modules.

The N’Gage solution developed by Energisme includes:

  • a module for analyzing heating, ventilation and air conditioning equipment and settings and monitoring indoor comfort
  • reports that facilitate the understanding and use of data, as well as collaboration with energy providers
  • alerts in case of abnormally low temperatures or excessive energy consumption of equipment

Cross-reference temperature data with occupant usage

Thanks to IoT sensors, it is also possible to cross-reference temperature data with occupant usage. This will allow the heating temperature to be adjusted based on the activity level of the occupants in a given space.

For building operators, temperature measurement results in many benefits, including:

  • a reduction in energy consumption
  • the ability to anticipate and prioritize energy retrofit needs
  • Improved occupant experience due to fewer temperature complaints in buildings
