20. How occupancy based lighting works (example) Provide light when and where it is required – an egress path for late night workers eliminates unnecessary energy usage after hours.
25. BASIC FLOW DIAGRAM OF ENERGY SUPPLIED FOR LIGHTING Human Impact on the Environment
26. 30% is radiated As heat i.e. 300KWh 70% is used For lighting i.e. 700 KWh Office/work space power supplied for lighting (for every 1000KWh) Additional Power supplied to air conditions to compensate 300KWh of heat generated by CFL lamps is 350KWh for 85% efficiency of AC CFL bulb Air conditions Additional cool air to Compensate Heat generated by CFLs Note: Maximum efficiency of CFL bulb is 70% and remaining 30% is radiated as heat Maximum efficiency of AC is taken as 85% Power supply Indirect savings
