Behaviour, Culture and Practice

• The longer involvement of stakeholder in the building process, the outcome more sustainability performance

Electricity Infrastructure• Day time demand change high• Early morning and late evening not much demand change

• Summer and Winter change in mid‐day is almost 2 times compare other time

Building Design vs Performance

• Building Design– Simulation

• Checking As Built– Simulation– Performance

• Checking As Occupied– Performance
