Optimization of SEML's tertiary real estate assets in Pessac - 23,500 sqm

Background

Since 2004, SEML Route des Lasers, a real estate manager and developer, has been supporting the establishment of companies from sectors of excellence in the Nouvelle-Aquitaine region. The company currently manages 70,000 m² spread across 4 business parks and 24 buildings. More than 70 tenant companies benefit from its services.

In 2022, this recognized player in local economic life is launching a call for tenders as part of its environmental approach initiated in 2009.

The contract concerns 16 new and existing tertiary buildings, spread across 3 sites.

The objective is to reduce energy costs and carbon footprint, to which are added certain specific expectations:

✅ Homogeneous and interconnected supervision and management of the 16 buildings concerned

✅ The possibility of remotely managing (PC and smartphone) consumption and anomalies in order to limit travel

✅ A scalable system for the company’s future needs

✅ A reliable data collection and analysis tool

✅ An installation without major works

Tailor-made solutions from Accenta

To meet these demanding specifications, SEML opted for Accenta’s Smart BMS.

This solution includes:

✅ Connection and integration of existing BMS

✅ Remote automatic control of heating and air conditioning by artificial intelligence

✅ Insight software solutions to track consumption and Optimzen to ensure dynamic and efficient operation of connected equipment

✅ Installation of a personalized management interface on the computer and PC of employees responsible for operating the device

✅ Support for launching the solution

The operation takes place in 6 stages:

1. Site visits, feasibility studies

2. Planning of needs: choice of temperature settings and time slots for occupation of each functional area

3. Installation of radio and wired probes

4. Integration of the program on the building, graphic and functional settings

5. Training in the use of the tools: 2 to 3 hours adapted to the profile and needs of the client; setting up the alert application, monitoring consumption, etc.

6. Development and adaptation of the tool in the form of a weekly meeting between SEML and Accenta.

Customer benefits

In terms of energy and the environment, SEML has reduced its energy bills and CO2 emissions by an average of -30%.

The high-performance BMS implemented also generates technical and regulatory advantages:

✅ Compliance with the BACS decree, which requires the installation or renovation of a BMS before 2025

✅ Energy monitoring and remote technical control of all buildings from a dashboard. It is therefore possible to react in real time in the event of a malfunction, thanks to customizable alerts

✅ The edition of enforceable data thanks to the IPMVP protocol applied by the Insight software. This Accenta exclusive meets the expectations of the tertiary decree, which requires that information relating to the consumption of each building be transmitted each year to the Operat platform.
