The award recognizes initiatives that turn responsible commitments into practical action. For Mantu, it highlights how technology and complementary expertise can help teams make better-informed decisions about the environmental performance of their workplaces.
Turning building data into actionable insights
Professional buildings account for 37% of global energy consumption and 34% of carbon emissions. With offices across more than 60 countries, Mantu set out to improve how it monitors energy consumption, understands space occupancy and manages its buildings.
The challenge was operational: data came from different sources, equipment relied on different communication protocols, and teams often had to identify anomalies through manual checks. Without a shared view of building performance, turning information into timely decisions was difficult.
To address this, Mantu Lab developed the Smart Building Management System, a cloud-based IoT platform that brings together building data and uses AI to analyse it continuously.
The project was launched at two pilot sites in Paris and Levallois-Perret, bringing together four teams: Mantu Lab, Sustainability, Real Estate, and Office & Facility Management. Each contributed to its expertise to build a solution that connects technical capabilities with everyday operational needs.
Four ways Smart Building is changing how we manage our offices
After months of development, the Smart Building Management System is now operational at two pilot sites in Paris and Levallois-Perret. The project has changed how Mantu collects, analyses and uses building data, with four concrete results.
1. One shared view of building performance
Energy consumption, temperature, air quality and space occupancy are now brought together on a single platform. Data from different sensors and equipment can be analyzed side by side, giving Sustainability, Real Estate, and Office & Facility Management teams a common view of how buildings operate.
2. AI-powered analysis to anticipate and act
By centralizing data and analyzing it continuously, AI models can forecast energy consumption and detect anomalies. The platform also provides recommendations through its AI Advisors, helping teams identify situations that require attention and make more informed operational decisions.
3. Three operational dashboards to support everyday decisions
The platform now runs across two pilot sites, with three dashboards covering building supervision, historical consumption and forecasts, and the assessment of potential gains by site and period. These tools help teams track environmental indicators, understand how office spaces are used, and coordinate maintenance activities.
By bringing occupancy, temperature, lighting and air quality into the same view, the platform also helps identify opportunities to improve working conditions and adapt office spaces to actual needs.
A dedicated module assesses the return on investment of recommendations by comparing the costs of the solution with expected energy savings, lower property costs and carbon benefits. This gives teams a basis for evaluating potential improvements and tracking expected gains.
4. A platform designed to scale
The project brings together Mantu Lab, Sustainability, Real Estate, and Office & Facility Management, combining technical expertise with operational knowledge. Its cloud-based architecture is designed to support progressive deployment across Mantu’s other locations.
The approach is also documented through scientific research, with work submitted for peer review at the IEEE Cybermatics Congress 2024 and FiCloud 2025.
Smart Building provides a shared technical foundation that Mantu can continue to develop and extend, turning building data into more informed decisions about energy use, space management and workplace conditions.
Turning responsible commitments into everyday decisions
Smart Building reflects Mantu’s approach to transformation: start with a concrete operational need, bring together the right expertise, and develop a solution that teams can use in practice.
Receiving the Impact Positif Award recognises the work of the teams involved and the progress made towards more informed building management. It also reinforces a broader principle: responsible commitments become actionable when data, technology and operational expertise work together.
With two pilot sites already equipped and a platform designed to expand progressively, Mantu is building a stronger foundation to monitor its buildings, identify opportunities for improvement and turn environmental objectives into everyday decisions.
