Maximizing Energy Efficiency through Integrated Building Management and Lighting Control Graham Martin Chairman & CEO EnOcean Alliance Energy Conservation Requirement

- Buildings Use >40% of our Total Energy Requirements

Transport - In 2030 the Global Electrical Power 28% Buildings 41% Demand will be 2 x that of 2003

- Government Directives to save Industry 31% Energy in Buildings: 20% by 2020 80% by 2050 Energy Savings by Building

Warm water Lighting 60% Electrical Cooling energy savings Heating in lighting

45% Electrical energy savings in climate technology

25% Energy Office building Office building savings in without automation with automation heating * Source: reference model of the LonMark survey according to DIN V 18599 ** Saving potentials according to LonMark survey 2007 of the technical college Biberach Require Sensors
