At dnergy®, our mission is to turn energy data into measurable results. Through dEEP, The Energy Efficiency Program by dnergy® and AUTOPILOT technology, we help real estate owners and asset managers transition from compliance-driven reporting to continuous performance improvement.
The following case studies illustrate how three leading clients in Belgium and Luxembourg — GECINA, PIMCO, and M&G — achieved significant energy and CO₂ reductions using dnergy’s expertise.
At dnergy®, our mission is to help visionary asset owners and managers turn data into real climate impact.
Together with our customers and partners — GECINA, PIMCO, and M&G — we’re proving that energy efficiency is not just a goal, but a measurable reality.
Each of the following case studies illustrates how dEEP, The Energy Efficiency Program by dnergy®, and AUTOPILOT solutions deliver tangible results: reducing energy use, cutting CO₂ emissions, and strengthening long-term asset value.
These projects reflect our shared commitment to a smarter, more sustainable built environment — one building at a time.
AUTOPILOT: Active
Period: 2024 - 2025
Building surface: 14,477 m² (offices)
BMS: Sauter
HVAC: Cold ceilings, reversible heat pump, convectors, 5 AHUs
Since dnergy® started its mission in January 2024, GECINA's energy consumption has decreased by 12.2%(climate-corrected), with improved overall performance and thermal comfort thanks to AUTOPILOT.
Within just three months, the first deliverables confirmed substantial operational efficiency improvements.
This BREEAM Outstanding (fossil-free, CO₂-neutral) building — also certified with BBC Rénovation, HQE Excellent, and BiodiverCity labels — uses environmentally friendly forms of energy such as geothermal energy and solar panels.
AUTOPILOT: Active
Period: November 2021 – August 2024
Building surface: 18,742 m² (offices)
BMS: Johnson Controls
HVAC: Cold ceilings, convectors, 5 AHUs
* dnergyʼs approach encompasses the implementation of good practices and the improvement of the usage of the existing technical equipment. AUTOPILOT is directly responsible for a part of the savings, and the implementation of our recommendations is responsible for another part.
PIMCO implemented AUTOPILOT to optimize their building’s performance through data-driven control and best-practice recommendations.
The site achieved an 18.4% reduction in energy consumption and a 17.1% decrease in CO₂ emissions, with return on investment realized within six months.

AUTOPILOT: Active
Period: November 2023 – December 2024
Building surface: 12,142 m² (offices)
BMS: Siemens
HVAC: District heating & radiators, 2 AHUs, chiller, chilled ceilings
* The savings presented are solely those resulting from dnergyʼs activity on the building and only account for district heating.
M&G’s facility integrated AUTOPILOT to manage district heating and chilled ceiling systems more efficiently.
Within the first six months, the site achieved 28% energy savings and 31% CO₂ reductions, demonstrating the power of intelligent control and actionable insights.
These three success stories illustrate how dEEP, The Energy Efficiency Program by dnergy®, and AUTOPILOT transform data into measurable performance.
Across diverse buildings, our combination of analytics, automation, and human expertise delivers tangible value — reducing energy costs, enhancing comfort, and contributing to a decarbonized future.
dEEP, The Energy Efficiency Program by dnergy® is designed for asset managers to unlock the path toward higher energy efficiency and proactive compliance across their portfolios.
With dEEP, a dedicated energy manager drives the process of mapping the current state, planning the improvement path, and acting for results while continuously measuring progress.
Our approach is powered by cutting-edge technology (AI, data analytics, and data) combined with action-oriented energy experts.
