2 What do I want to tell you? Initial situation in Wuppertal Organisation Energy controlling Processing energy data Management Rules and standards Energy concepts User motivation and consultation Financing Energy procurement Reporting 2

3 Information about Wuppertal 347,945 residents (30 June 2012) 196,624 apartment units (31 March 2012) 191,296 registered vehicles (30 June 2012) Total city area: km 2 City perimeter: 94.5 km 3

4 Initial situation in 1997/98 prior to GMW establishment Decentralised building maintenance in various service sectors, e.g. school management Remainder done by municipal building authority for planning, new construction and building technical equipment Completely dispersed responsibilities for other building services Financially: absence of full cost invoicing and presentation of economic effects of energy saving investments 4

5 Organisational goals for facility management Consolidation of all activities related to buildings Cost effectiveness as the basis Making floor space a cost factor for users Founding of an independent facility management organisation Placing all municipal public buildings within a special asset pool Leasing buildings to the various municipal offices 5

6 Facility management: What s that? Totality of technical infrastructural services administrative that serve the operation and use of a building Targets: Comprehensive service offering for building users, Compilation and minimisation of all cost related to the provision of services 6

7 Structural info about GMW Independent enterprise created in accordance with municipal codes Established offices with 1,380 units, of which 840 are our own buildings Around 1.5 million m² floor space Total of 405 staff: 190 building staff, receptionists, superintendents 125 architects, engineers, technicians 40 commercial staff (workshop) 50 administrative staff members Energy management: Yearly revenue of EUR 16 million 42 GWh electricity including street lighting 130 GWh heating, 550,000 m³ drinking water 7

16 How do we do it? Organisation Energy controlling 16

17 Energy controlling tasks Overview of energy and water use in all buildings Compilation of specific consumption per area in order to estimate potential energy savings Compilation of acute use irregularities in order to improve operational management 17

18 Analysing collected data Consideration of individual objects Monthly consumption development Yearly consumption development Comparing monthly consumption for same months Identifying key figures in order to estimate energy savings potential Inspection of demand distribution. Identifying irregularities Christian Gleim, Gebäudemanagement der Stadt Wuppertal 18 18

26 How do we do it? Organisation Energy controlling, energy certificates Processing energy data Management 26

27 Management tasks Make sure that facilities requiring energy are only in use when they are needed! Avoid unncessary operation of: heating systems, air handling and air conditioning systems, lighting, pumps, etc. 27

28 Operating comprehensive building technical facilities Digital regulators and remote operation of HVAC systems are dependent on: outside temperatures, room use, air quality, etc. Lighting management via motion sensors and daylight control Central outage management 28

29 Monitoring of the opera s audience space 29

30 Current number of buildings connected with control systems 120 schools 46 gymnasiums 5 nursing homes 4 indoor swimming pools 8 day care centres 9 administrative buildings 1 orphanages 2 main fire departments Also: a synagogue, various zoo buildings, vehicle fleet garage Chemical Analysis Authority, v.d.heydt Museum, Automobile Inspection Office, orchestra practice hall, professional swimming centre, city auditorium, opera hall, Haus d. Jugend Elberfeld, Stennert Meeting Place, and so forth. 30
