Maintenance Green Wall or Green Wash

by John Herbert
Hong Kong’s urban landscape is harsh, concrete won that battle long ago. However to increase the greenery area the vertical green wall concept is often used to supplement the missing green lawn, but as this video clip shows, your green wall might be burning more diesel fuel than you thought….

We need to spend more time, and money, not less, to properly designing our buildings and landscaping areas. Of course this idea is not limited to green walls, continuous honing and refining is required for buildings too. Here is an example, the BMS (Building Management System) often touted as the saviour for building managers, set and forget.

Yet after the BMS installation in a Hong Kong commercial building, the energy consumption and energy bills actually increased! Yes, it demonstrates that the system was not commissioned correctly, and after the BMS provided the solution, nobody was minding the store, nobody monitored the energy consumption. Often People assume that because the computer is handling it, it must be ok. However,┬áin reality the data shows the operating cost and carbon emissions increased. I don’t need to visit this building to know there are problems, the data shows the problem.
