Square Sense

Square Sense is a fast-growing platform that provides advanced data solutions to global real estate developers, investors and managers. The company builds AI-powered “building brains” that support the digital transformation of investment and asset management, and improve the operational and financial performance of real estate assets.

These brains provide real-time pattern interpretation of user community profiles and service performance, and enable autonomous optimization to greatly enhance the user experience for the tenants and the asset/portfolio management strategy execution such as investment, net income or ESG.

Square Sense was founded in 2017 in Paris by a multi-cultural team of talented engineers and data scientists.

Data analysis @ Square Sense

Square Sense is developing products to understand people's behavior and building performance using data collected from sensors and systems within a building. Our models infer knowledge using data from heating, ventilation, and air conditioning (HVAC) systems, lighting, smart meters, Wi-Fi, people counting & occupancy sensors, access control systems, elevators, air quality sensors. These models are based on statistics, probabilistic models, machine learning, and deep learning. The understanding of how a building is used and how it performs under various conditions is used to devise and implement strategies to reduce operating costs, improve the user experience, and increase revenue. Our goal is to develop decision-making support systems and autonomous optimization routines, both at the building level and at the portfolio level (i.e., for clients that own several buildings). An example of decision-making support is a product that quantifies the possible yearly energy savings effectively obtainable by improving the thermal insulation of the building given knowledge of how the building is used. An example of autonomous optimization is the automated and dynamic optimization of the thermal comfort and the energy consumption of the building given current and predicted building occupancy.

Data analysts at Square Sense are responsible for supporting decision-making using available data within client-specific projects (involving one or multiple buildings). Their tasks include quantifying relationships between different variables under various circumstances (e.g., actual or projected), and identifying trends and patterns. They work with the data produced by our data pipeline, which is developed and maintained by our engineers and scientists, and which collects sensor data, transforms this data using various algorithms and models, and stores the results into an analytical database. Data analysts use business intelligence software such as Tableau and PowerBI, as well as Python-based tools (Plotly, Dash, pandas, Matplotlib) to perform their tasks.
