7. Energy Costs in Office Buildings In a typical 40,000 sqm building % out of Opex 45-50 % out of tot. costs 35-40 out of which - Electricity 70% Heating 30% out of which - A/C costs 45%

8. Electricity Management in Office Buildings - Currently • The bill for electricity is given as a whole • No energy balance • Tenants’ billing is based on human reading of meters • Tenants are not charged with “common” consumption such as air-conditioning on a measured basis • Tenants complain because of cross- subsidizing • Meters are of low accuracy level

9. Electricity Management in Office Buildings – Currently (cont. ) • The billing, charging and collection process is time consuming and therefore costly • No flexibility in time-of-use tariffs • No tracking of historical data • No control over the meters of utility company Results in non-efficient energy management

10. The Solution in Office Buildings

11. Purchasing Electricity Effectively Taking advantage of the liberalization in the energy market and purchasing electricity at lower tariffs. Most effective way to reduce tariffs is by relating purchases to historical measurements of power demand all year around.

12. Light Energy Saving The “Lighting Energy Controller” (“LEC”) ensures about 25% of saving in electricity consumption for lighting. ROI in up to 2 years

13. LEC Voltage Control

14. Lamps Lifetime H.P.S lifetime bulbs VS voltage Lamps still working Working hour(x1,000)

15. Lamps Intensity Although the initial luminous flux is reduced by up to 10% the trade-off is a longer lifetime and improved luminous flux in the long run. Luminous flux VS life time on H.P.S lamps Flux % Working hours (x1,000)

16. Cooling and A/C Energy Saving • Energy savings of 15-30% due to improved efficiency of the process • The solution is based on 20 individual patents • More than 20,000 worldwide installations • ROI of up to 2,5 years

17. The Installation

18. Benefits Only • Reduction of pressure by 30-60PSI • Longer system lifetime • Humidity reduction • Improvedconditions of heatexchanger • 15-30% lower energy consumption
