OPERAT Reporting and the French Tertiary Decree: The Complete Guide

athermos@kuzzle.io (Alicia Thermos) — Fri, 14 Aug 2026 13:19:28 GMT

Under the French tertiary decree, the OPERAT platform has become a mandatory step for every organisation subject to energy consumption reduction requirements in the tertiary sector. Understanding how it works, keeping track of deadlines, and anticipating penalties: here's what you need to know to stay compliant.

Tertiary Energy Performance: Challenges, Regulations, and IoT Solutions

athermos@kuzzle.io (Alicia Thermos) — Fri, 14 Aug 2026 13:15:04 GMT

Energy performance is often reduced to a single label, the one given by an Energy Performance Certificate (EPC). Yet for the tertiary sector, the stakes are far broader and the obligations far more structured. An EPC gives a static snapshot of a building; tertiary energy performance, by contrast, follows a dynamic trajectory that is managed, measured, and reported every year.

BACS Decree: Our Complete Guide

The energy transition of tertiary buildings is accelerating. Faced with the climate emergency and France's commitment to cut its energy consumption by 40% by 2050, lawmakers have introduced a series of structural regulatory obligations for the professional property sector. Among them, the BACS decree plays a central role: it requires the installation of intelligent automation and control systems in all significant tertiary buildings. For property portfolio managers, local authorities, and businesses, understanding the stakes, deadlines, and available funding levers has become a strategic priority. It's also an opportunity: to turn a regulatory constraint into a profitable investment, thanks in particular to IoT technologies and hypervision platforms such as those developed by Kuzzle.

BMS / BEMS: Definitions and Examples with IoT

athermos@kuzzle.io (Alicia Thermos) — Fri, 14 Aug 2026 12:50:10 GMT

In a context of accelerating digital transformation, local authorities and building portfolio managers are looking to optimise their infrastructure while keeping energy spending under control. Building management is at the heart of this challenge, and two systems keep coming up in smart city projects: BMS and BEMS. Though often confused, these two systems cover distinct realities, and understanding them is essential to getting the most out of modern IoT solutions.

How Is IoT Transforming Heritage Management in Connected Territories?

athermos@kuzzle.io (Alicia Thermos) — Fri, 14 Aug 2026 12:46:43 GMT

The Internet of Things has become one of the main levers for modernising public heritage in connected territories. By continuously collecting data from sensors deployed in buildings, public spaces, and urban infrastructure, an IoT platform helps optimise energy performance, occupant comfort, and maintenance, while meeting local authorities' regulatory and climate requirements.

Through a hypervision approach, IoT unifies supervision across an entire estate: schools, gyms, town halls, swimming pools, museums, libraries, performance venues, administrative offices. Data is centralised, tracked over time, and put to use, shifting from reactive management to predictive management of public assets, whether at the scale of a single building, a district, or an entire metropolitan area.

Pioneering smart cities such as Lyon, Dijon, and Paris demonstrate every day that harnessing IoT data at scale reduces consumption, improves service quality, and supports ambitious ecological transition strategies. At the local authority level, this data-driven approach becomes a genuine governance tool for more sustainable, more resilient territories.
