3.3 Energy Saving
Concepts and Principles
Energy saving results from conscious efforts to reduce energy consumption.
There are four main categories for energy conservation:
Climate Positive Design
Designs such as window films, double glazing window, blinds and curtains,
solar tube and other climate positive designs to be introduced in this section are
considered climate positive design (also known as passive designs).
Energy Efficient System
EMSD Grade 1 energy labelled air conditioning units, occupancy sensor
controlled lighting, LED lighting, heat pump water heaters, EMSD energy
labelled appliances, etc. are considered energy efficient system which can meet
the occupancy demand in an energy efficient way.
Renewable Energy System
Adoption of renewable energy sources, such as solar and/or wind energy
contributes positively to energy demand of schools and serves educational
purposes.
Energy Management
Another major component of energy conservation is to monitor and manage
energy demand by using energy and/or smart metering for major building
systems in order to record the system performance especially in implementation
of green initiatives and student participation in monitoring their behavioural
impact on energy usage.
