Over the past decade, there has been an explosion of data. This is especially true in commercial buildings, which have been identified as noble examples of embracing sustainability and decarbonization. The challenge asset and facility managers face now is what to do with these mountains of energy-related
information. Raw energy data - data without context - can be confusing. With no perspective, it provides few clues about areas of energy waste or overconsumption. Nor does it provide any evaluation
of ways to bring energy bills under control.
Our company, Hexeis, is a Schneider Electric EcoXpert Master Partner in Power Management. In our experience, there are three important elements of data - accuracy, availability, and timeliness. Each impacts the sustainability and carbon footprint of your operations.
Pillar 1: Accuracy of energy data is the starting point
Connected, digitized power meters installed on a building's key circuits provide large amounts of energy-related data, and their accuracy is vitally important. Any miscalculations during installation can result in potential miscalculations that can persist unnoticed over extended periods.

For example, in providing our customers with digitalization and electrification solutions, we've noticed a 20% error rate in meter installations. Within those, we identified 31 potential mistakes. These can range from basic errors like incorrectly programming current transformer (CT) ratios to more elaborate missteps like installing a CT backward. Besides the obvious safety risks, these incorrect meter installations can lead to data issues that cause measurement errors, incorrect billing, operational inefficiencies. It can even jeopardize your sustainability progress.
The importance of accurate energy data even ventures into legal territory, particularly in the context of NABERS (National Australian Built Environment Rating System). This Australian rating system measures the environmental performance of buildings. NABERS helps building owners and managers identify areas to improve their environmental performance and reduce operating costs. Inaccurate meter data can lead to incorrect ratings and potential legal penalties.
