O p t i m i z e R O I a n d o c c u p a n t e x p e r i e n c e Offi ce buildings come in a variety of shapes and sizes. They also offer different levels of amenities. However, all offi ce buildings must meet a common set of requirements: > Optimise energy effi ciency, e.g. by adjusting energy consumption to actual needs. > Be fl exible enough to allow offi ce space to be restructured as old occupants move out and new ones move in. > Improve the working environment and quality of life. > Comply with health, safety and energy standards and regulations. C h o o s e s o l u t i o n s t h a t m e e t y o u r u n i q u e n e e d s > Secure, reliable power supply systems. > Energy effi ciency audits and assessments. > Energy consumption tracking and analysis. > Optimised control of heating, ventilation, air conditioning, lighting and blinds. > Secure, supervised access to buildings. > Fire safety systems. > Integrated voice/data/image networks.

Rising energy costs and environmental awareness have spurred investors, developers, builders, operators and occupants to make their buildings more energy effi cient. But to truly optimise building energy consumption, you need detailed, accurate data about how that energy is being used. of the energy consumed by an offi ce building is used for lighting and HVAC 9
C o n s u m e s m a r t e r a n d c o n s u m e l e s s Track and manage consumption to detect opportunities for savings Installing tracking equipment and analysis software can provide you with valuable information on building operations and energy consumption. Setting up and analysing energy indicators is an effective way to pinpoint consumption peaks and energy losses. You can then take targeted corrective measures and assess their impact. A B C D E F G kwh/m 2 /year Optimise building energy consumption There are several ways to strike the best balance between occupant experience and energy consumption: > Use reactive energy compensation to improve the quality of the energy used and get the best possible utility rates. > Install variable-speed drives on pumping and ventilation systems. > Manage indoor and outdoor lighting systems; install manual switches, timers and light or motion detectors. > Manage and integrate heating, ventilation, air conditioning and window-blind operation. > Manage heating, ventilation, air conditioning and window-blind operation independently, zone by zone, depending on actual occupation, exposure, etc. > Improve power supply reliability and security by correcting the power factor and reducing harmonics. 10
Buy energy at prime rates by using targeted information to select the best utility rate on a given day. > Install hardware and software to automate consumption tracking. > Monitor consumption logs and profi les. > Predict energy demand. > Analyse utility rates and generate virtual use scenarios to assist in decision-making. > Consider the possibility of consolidating consumption data from several buildings. Fitting variablespeed drives to HVAC and pumping equipment can reduce consumption by 50% > Negotiate rates with utilities: Based on the combined consumption of several buildings. Avoiding consumption peaks by shutting down pre-selected equipment to reduce load. Use renewable energy resources to produce electricity, by investing in solar panels, for instance. > Supply, manage and secure the energy your buildings need. 11
S u s t a i n m a x i m u m p e r f o r m a n c e l e v e l s Sustaining maximum performance over long periods of time is a real challenge. Buildings and insulation materials age, offi ce uses change and occupants tend to reduce performance through day-to-day habits like changing air conditioning settings or forgetting to turn off lights. However, there are solutions that can help you improve performance. Our active energy-effi ciency solutions incorporate various levels of service from simple audits to comprehensive Energy Effi ciency Contracts. These contracts include an obligation to generate savings that will pay for some or all of the building improvements made. > Set up management tools to track and analyse data. > Carry out scheduled maintenance. > Keep upgrades consistent throughout the building s lifetime. > Provide training on products and systems. 12
I m p l e m e n t e n v i r o n m e n t a l l y - s o u n d p r a c t i c e s A building s environmental impact and carbon footprint must be taken into account from the design stage and at each phase of construction. At Schneider Electric, we integrate eco-design into all of our solutions: > Lower building energy consumption. > Recyclable materials. > Lower volume and/or weight to lessen impacts related to transport and end-of-life waste quantities. > Manufacturing processes that generate less pollution. The difference between the energy effi ciency calculated at the design stage and the actual effi ciency during use can be up to 25%. The only way to reduce this difference is to monitor effi ciency on a regular basis. Our solutions also comply with international standards (RoHS Directive) concerning the disposal of hazardous waste in obsolete electrical and electronic equipment. We also offer end-of-lifetime equipment management and disposal solutions. 13

F l e x i b l e, u p g r a d e a b l e b u i l d i n g s A fully-occupied building is a profi table building. To maximise occupancy rates, offi ce buildings must be fl exible enough to be restructured quickly and inexpensively. Smart offi ce building design allows partition walls to be changed quickly and easily, new safety functions and facilities to be added, workstations to be reorganised and power, data and lighting networks to be modifi ed effectively putting your building to work full time. B u i l d b e t t e r a n d f a s t e r Use prefabricated equipment that is easier to connect, reducing construction delivery times. Examples include modular electrical switchboards, prefabricated wiring systems, pre-wired power sockets and data outlets, etc. Simplify the integration of all technical facilities by using open, standard communication protocols. In today s buildings, electrical wiring must be integrated into Building Management Systems (BMS) from the very beginning. 15

S a f e r, m o r e e f fi c i e n t b u i l d i n g s Safe, effi cient offi ce buildings optimise temperature, lighting, ventilation and noise and provide convenient access to various networks when and where they are needed. They also guarantee the safety of employees and the security of property and data. Making it easy for building occupants to use energy more effi ciently can have a positive impact on comfort, safety and productivity not to mention your bottom line. M a k e o f fi c e s e a s i e r t o u s e Regardless of how each offi ce fl oor is organised, our solutions guarantee that each workstation will be close to wall sockets, voice/data/image connections and HVAC and lighting controls. Bring controls closer to users, and provide climate control in the offi ce or a particular area through the use of multiple temperature, light, motion and CO 2 detectors. Integrate power and network sockets discreetly into walls, fl oors or furniture using removable modules. A wide range of equipment and designs are available offering up to six functions conveniently grouped together at the same access point. Place flexible, easily adjustable connection boxes and posts near meeting tables and offi ces. Maintain constant lighting levels by adjusting lighting intensity according to changes in natural light. Well-designed and comfortable offi ces can increase employee productivity by up to 2% 19

Total safety is guaranteed through differential protection, preventing any risk of electrocution. Integrate building security into a solution that can combine up to fi ve essential functions: access control, intrusion alarm, fi re alarm, CCTV and safety lighting. In the case of fi re detection, for example, the CCTV system will display images of the location where the alarm has been triggered. 21
