EcoCampus: Implementation Plan

Key Research Topics Research Focus Areas

1Green building systems for the tropics

• Tropical façade and lighting • Energy efficient IAQ provision (cooling,

ventilation & dehumidification systems)• Innovative Data centre cooling

2Sustainable Urban mobility

• Electric Vehicles and charging systems• Efficient Public mover/shuttle vehicles• Smart Personal Mobility concepts

3Renewable energy integration/Smart Grids

• Smart microgrid management with AC/DC architecture

• Efficient and low-cost Energy Storage systems

• Demand Response Management

4Energy InformationAnalytics

• Wireless Sensors and communications• Smart Metering & Monitoring systems• Big Data analytics

5User Behaviour for Energy Conservation

• Gamification and Sociological concepts for user engagement

• Behavioral economics for energy savings
