What Challenges Do Building Owners Face Without BEMS?
The journey to building energy optimization is often complicated by the lack of visibility, control, and automation that BEMS provides. The most common issue is the inability to track and analyze energy consumption in real time across different building systems.
Another significant problem is the reactive approach to energy management, where issues are only addressed after they impact operations. According to industry research, an MIT study found that buildings waste at least 30% of their energy, which BEMS can avoid.
Additionally, many building owners struggle with the complexity of energy data and the inability to identify optimization opportunities. Without proper analytics, organizations miss opportunities for savings. At Nowistech, we have found that buildings with BEMS identify 2-3 times more energy savings opportunities than those without.
Consequently, building owners without BEMS face higher energy costs, reduced occupant comfort, and competitive disadvantages. Finally, many building owners lack the ability to demonstrate sustainability progress to tenants and stakeholders.
