Renewable energy is natural energy which does not have a limited supply. Renewable energy can be used again and again, and will never run out. Examples of renewable energy sources include biomass, hydro energy, geothermal energy, solar energy, tidal energy, wave energy and wind energy
In the ZCB, renewable energy is generated on site from solar energy by photovoltaic (PV) panels and from biofuel (one kind of biomass) made of waste cooking oil. Please click here for more details.
Biofuel is a type of fuel derived from organic matter (obtained directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes) instead of from fossil products
A study has been carried out to assess the solar irradiance levels at various parts of the site, to determine the viability and layout of photovoltaic panels. Three types of photovoltaic panels have been chosen for various locations
Solar thermal hot water system is installed on the roof of Eco-café serving the hot water demand of Eco-café
The adsorption chiller uses water as refrigerant, a silica gel as adsorbent, and hot water as main power source. The evaporator section cools the chilled water through adsorption of the silica gel, while the hot water regenerates (“dries”) the silica gel
