Why we partnered with dnergy? There are two moments a developer can involve an energy partner. After handover, when the building is not doing what the model said it would, and somebody needs to find out why. Or before. At dnergy® Day, Julie Willem shared how the Atenor Energy Compass helps structure energy performance considerations throughout the development process. From design and engineering to construction, handover and operation, the objective is to connect each stage and support the transition from calculated performance to real-world results. Through its collaboration with dnergy®, Atenor brings additional independent expertise into this process, strengthening the way energy performance is assessed throughout a building's lifecycle. That is the reason for the partnership. Not expertise they lacked, but verification they could not perform on themselves. Checks at defined moments, by a third party, against their own framework. Which is also why dnergy® was brought in before the problems rather than after them — during design, engineering, construction, handover and occupation, so each step holds before the next one starts. The numbers don’t lie, but they need to work #dEEP #dnergy #wearednergy #RealEstate #BuildingPerformance #Commissioning

Buildings are designed for people. At dnergy® Day, Julie Willem shared an important reflection on the relationship between energy efficiency and how buildings are actually used. Reducing energy consumption matters. But a building also needs to be comfortable, attractive and relevant to the people who live or work in it. The real challenge is to bring these dimensions together: improving energy performance while creating places that people want to use and that remain resilient over time. Because the long-term value of a building is not defined by energy efficiency alone, but also by the people it serves. Which is why comfort is a constraint in how we steer, not a variable we trade away. The objective inside dEEP is holding temperature within the comfort window during occupied hours, while consuming less to do it. Not less energy at any cost. Efficiency without use intensity is an empty building. Use intensity without efficiency is a stranded one. Both, or neither. #dEEP #dnergy #wearednergy #RealEstate #WorkplaceExperience #EnergyEfficiency

These are not marketing numbers. A number from dnergy® Day, and then the more interesting thing about it. At dnergy® Day, Julie Willem, ARCHILAB Director at Atenor, shared how the environmental performance of real estate projects can be translated into more tangible figures. Based on project-level calculations, Atenor's current development portfolio could represent approximately €6 million in annual energy savings if fully realised, compared with equivalent projects developed solely to meet the applicable regulatory requirements. Beyond the figure itself, what matters is the methodology: assessing each project individually, challenging assumptions and translating sustainability ambitions into measurable outcomes. Small remark, large accusation. The reason she has to say it is that plenty of numbers in real estate energy are marketing numbers. Rounded, unsourced, borrowed from a sector average, repeated until they sound like measurement. The difference is not rhetorical. A calculated number can be wrong and then corrected. A marketing number cannot be wrong, because nothing is actually being measured. This is also why savings inside dEEP are verified against a baseline following IPMVP. Verified, not estimated. It is slower. It is the only version that survives contact with an asset manager who checks. #dEEP #dnergy #wearednergy #IPMVP #AssetManagement #RealEstate

Before automating, you need alignment. Eighteen months. Nineteen buildings. Most of them well underway. At dnergy® Day, Charles Heymans, Asset Manager at Ethias Real Estate, said he had asked us early on whether seven buildings in eighteen months was not a little slow. He then explained why he no longer thinks so — three reasons, in sequence. Before you optimise, you repair. Before the first tonne of CO₂ is saved, you may need to fix a badly configured BMS, displaced sensors, valves left open. The unglamorous inventory no-dashboard shows you only when somebody goes and looks. Before you automate, you align. Without buy-in from everyone involved, the system simply sends signals and alerts that nobody understands or has approved. And before you measure a gain, you need a sound baseline. Floor areas can be wrong. Proxies differ between property managers. Manual meter readings carry errors. If the baseline is wrong, the results mean nothing. This is the part of energy performance that does not fit in a product demo. It is also the part that decides whether the results hold. Where does your portfolio actually sit — repair, alignment, or baseline? #dEEP #dnergy #wearednergy #EnergyManagement #FacilityManagement #RealEstate

Every building has a gap. The gap between the performance a building was designed to deliver and the performance it actually delivers At dnergy® Day, Stephane Jans, our Chief Product and Technology Officer, showed why that gap is not merely a technical problem. It starts with equipment that no longer works as intended. That defect creates discomfort. Discomfort creates complaints. Complaints become official complaints. Official complaints become problems inside tenant contracts. And at the end of that chain we get: resale risk, and pressure on the value of the asset. So the gap is not only a CO₂ number or a certification score. Eventually, it affects the tenants, the contracts, and the balance sheet. Moreover, a building that consumes more energy is not necessarily a more comfortable building. In many cases it is a less comfortable one, revealing something not working. Which is why the energy question, the maintenance question and the asset value question are the same question. dEEP treats them as such. #dEEP #dnergy #wearednergy #AssetManagement #BuildingPerformance #ESG

"Nobody showed me how to turn the key." A real estate developer, describing one of their own buildings. High standards in the calculations. High standards in the simulations. Designed to BREEAM Excellent. Everything the team believed in went into it. It ended up consuming a few times more than it was supposed to. At dnergy® Day, Julie Willem, who leads ATENOR’s ARCHILAB research laboratory, described what happens to a developer’s confidence when reality arrives — and the conversation with our co-founder Benjamin De Dycker that produced the line she still uses: "A Ferrari, driven in first gear on the motorway." What stays with us is what the technical manager on site said next. I know I have this beautiful building in my hands, but nobody showed me how to turn the key. And then the part most developers skip. Atenor decided the problem was theirs. Not just delivering a beautiful building, selling it, signing a tenant — but making sure what was calculated is what actually happens. Or, when it doesn’t, knowing why. Through this collaboration with dnergy®, the building was brought back to its expected calculated consumption within about a year — with every reason to believe its performance can improve even further in the years ahead. A building is not delivered the day the keys change hands. It is delivered the day someone can operate it as designed, and prove it. Who is steering your building today? And how would you know if nobody was? #dEEP #dnergy #ATENOR #wearednergy #EnergyEfficiency #RealEstate #BuildingPerformance
