Electricity costs often represent the largest operating costs item for operators of data centers. Efficient energy use saves resources, generates an image boost, and contributes to successful positioning in competition.
This is the objective of the Trusted Site eEfficiency (TSe2) audit and certification program of TÜViT. It supports the operators of data centers in developing systems and processes that allow the continuous improvement of their energy efficiency.
Reduction of energy costs
The Trusted Site eEfficiency (TSe2) certification program of TÜViT defines measures and structures based on the international standard for energy management systems (DIN EN/ISO 50001). With Tse2, TÜViT offers periodic inspections with certification of the maturity level. This identifies savings achieved, and promotes sustained optimization of energy efficiency.
Maturity level certification
The certification process does more than just determining the status quo. Thanks to the increasing requirements during maturity level certification and the introduction of an energy management system, companies continuously optimize the use of energy resources.
