The document discusses best practices and recommended architectures for energy management in green buildings. It recommends a zoning approach that respects the physical structure of buildings with multi-applicational control at the zone level and centralized control. The architecture should be based on IP networks, scalable, and integrate all subsystems for interoperability. Key principles include optimizing energy efficiency through people engagement, passive design, active efficiency measures, and performance monitoring.

2. Challenge  Mastering Consumption without compromising comfort & flexibility Office Buildings use too much Energy - v/s no. of hours occupied + Peak demand issues Commercial Buildings use ~ 18 % of world energy

3. Energy Efficiency ~ 3 Levers People Engagement kWh / m 2 Structure+Materials Architecture & Design Equipments & Fixtures Operations Performance Sustainability Change Management Energy Audits Solutions Building Management Monitoring & Control Report & Tools Passive Energy Efficiency Active Energy Efficiency Active Energy Efficiency

6. Respect the physical architecture of building “ view building” Floors + Zones “ classify areas” Ambience &/or Usage Work-place ‘or meeting rooms Public areas & parking Different Utility areas … also helps in ensuring Flexibility & Scalability
