Eco-design and Construction


Renewable Energy Installation

In order to reduce carbon emission, and align with the Government's policy, the Hong Kong Housing Authority (HA) has integrated various renewable energy applications into the design of public housing estates since 2003. These include solar and/or wind powered outdoor lightings, solar powered audio tactile estate map, grid-connected photovoltaic (PV) systems, building integrated photovoltaics (BIPV), etc.

PV Systems

A pilot grid-connected mono-crystalline silicon PV system at Lam Tin Estate has been in operation since August 2009. Its power output can cater for part of the electricity demand of the estate’s communal facilities.

In view of the satisfactory performance of the pilot PV system, the HA decided in 2011 to implement grid-connected PV system in all new public rental housing developments to provide each domestic block with at least 1.5% of the communal electricity demand as far as practicable. Meanwhile, we will continue the search and piloting of other renewable energy technologies for application in public rental housing estates.

Solar-powered Lights

To enhance the community awareness of environmental protection, we have installed one to two solar-powered lights in each of the PRH and HOS developments for educational purpose.
