Attitude of Europeans Towards the Environment
“The state of the environment (72%) influences the quality of life as much as social factors (72%), economic factors are perceived as slightly more important (78%)”

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%

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 metersTenants are not charged with “common” consumption such as air-conditioning on a measured basisTenants complain because of cross- subsidizingMeters are of low accuracy level
9
Electricity Management in Office Buildings – Currently (cont. )
The billing, charging and collection process is time consuming and therefore costlyNo flexibility in time-of-use tariffsNo tracking of historical data No control over the meters of utility company
Results in non-efficient energy management

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.

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

Luminous flux VS life time on H.P.S lamps
Flux %
Working hours (x1,000)
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.
