At the inspiration day of VVSG's Climate Network on As A Service and Energy Efficient Patrimony at the BAU House in Sint-Niklaas, Sint-Niklaas' Alderman for Buildings Bart De Bruyne presented the first results of the energy savings project based on Factor4's Building Performance Contract. The city will achieve energy savings of 39 percent over the next ten years in nine of its buildings that consume the most. To that end, the city entered into a performance contract with Luminus Solutions. Factor4 acted as facilitator. Minister Tinne Van der Straeten saw that it was good.
During his keynote, the alderman called the partnership between the city and Luminus a marriage: “We entered into a long-term relationship with Luminus to put those nine buildings in their hands so they can make energy-saving investments there, and provide the necessary maintenance and monitoring.”
The city had Factor4 accompany it in the preparation of the contract. All possible dates of the buildings were inventoried, down to the smallest details. The contract was then put on the market. Luminus Solutions offered the most attractive proposal in terms of savings and investments. The contract started on January 1, 2022 and runs for ten years.
Luminus Solutions is responsible for the energy-saving investments, maintenance and adjustment of the installed installations, monitoring and reporting. Uniquely, residual value is also included in the contract. At the end of the contract term, the residual value of the building must be at least equal to the value at the beginning of the contract. That is, the condition of the building must not decrease. This allows the ESCO to invest in measures with a payback period longer than 10 years, the term of the contract.
"The innovative nature of this EPC project allows us to go the extra mile. It is a vision over a longer period with staggered budgets and proportionally a maximum of energy savings. This gives us more room to implement measures on the one hand and to guarantee much higher guarantees to the city on the other."

Als gebouwbeheerder moet je veel bordjes omhoog houden. Je moet voldoen aan steeds strengere energie- en klimaatwetgeving (zoals EPC NR), structureel en kostenefficiënt onderhoud organiseren (via onder andere conditiemetingen en MJOP’s) én tegelijk de energiekosten onder controle houden met gerichte energie-audits. In de praktijk lopen deze trajecten vaak door elkaar, terwijl de bijhorende data verspreid zit over verschillende systemen en rapporten. Het overzicht raakt zoek en dat kost tijd en geld.

In 2010 onderzocht Factor4 als eerste Belgische adviesbureau de toen relatief nieuwe en veelbelovende Nederlandse norm NEN 2767. Deze norm maakt het mogelijk om de technische staat van bouwdelen en installaties eenduidig, objectief en reproduceerbaar vast te stellen.

Investeren in comfortabele werkplekken loont. Dat bewijst VDAB met de resultaten van haar meest recente Comfortmeter-survey, uitgevoerd door Factor4. Na een eerste meting in 2017 werd in de winter 2024-2025 opnieuw gepolst naar hoe medewerkers hun werkcomfort ervaren. Het resultaat? Een merkbare vooruitgang in tevredenheid én welzijn op de werkvloer.
