HCM CITY — Using effective lighting solutions in high-rise buildings can help save electricity and reduce the emission of greenhouse gases, a seminar heard in HCM City on Friday.
Experts from Dutch electronics giant Philips said since multi-storied office buildings consume 30 – 40 per cent of the total power used in a typical city and lighting accounts for around 35 per cent of their power consumption, it is a significant opportunity to save power.
Nguyen Van Phuoc of the city's Department of Natural Resources and Environment said high-rises over the world account for around 33 per cent of all carbon dioxide emitted into the environment.
HCM City tests quality of groundwater
HCM CITY — The Department of Science and Technology is collecting 1,800 underground water samples in Go Vap District in HCM City to test for pollution level.
Based on the testing result, the department will propose measures to prevent pollution and limit the exploitation of underground water.
Underground water 50 metres beneath the ground surface is seriously polluted, especially in areas surrounding industrial parks and export processing zones in HCM City as well as Binh Hung Hoa Cemetery.
The excessive exploitation of underground water has also led to land-surface subsidence in many areas in District 6 and Binh Chanh and Thu Duc districts.
