Building Efficiency Servicesand ICT
Environment
The building efficiency imperative
41%buildings’ share of global emissions
CO2 31% industry
28% mobility
Up to
80%of building costscome fromoperations
30% maintenance
40% energy
Meeting the new types of competitive disruption demands new cost efficiencies and a greener market image
Volatile energy prices drive new requirements in strategic energy procurement
Increasing cost pressures demand optimized energy procurement, energy efficiency and consumption control
Increasing environmental and non - financial reporting regulations demand new capabilities in energy efficiency and carbon management
Real estate is often
the 2nd largest expenseon organizations’ income statement
500climate laws passed in 66 of the world’s largest emitting countries
50%of the energy consumed by buildings is wasted
