Hi Everyone, We are working on a building that already got LEED C&S certificate in 2012 and now aims to get EBOM.

Is a site which is located on a teritory of a previous coal mine considered perviously developed?

We want to use paving block as one of the hardscape surfaces.

In my project there are two areas dedicated for parking.

Is providing leaflets in the reception of the building and case study on the owner's website enough for the Green Building Education Program?

Is it necessary to calibrate sensors during the performance period even if the manufacturer’s recommended interval didn't pass yet?

I am working on a project (shopping mall) that will have revolving door as the mail entrance and it will be equipped with a permanent walk-off system.

Should retail spaces in a shopping mall have CO2 sensors? Does anyone know if shops are treated as densely occupied spaces?

Are CO2 sensors required in locker rooms? Loker rooms are non-regularly occupied spaces but they are also densely-occupied spaces.

In our case, the wooden walls are produced by a German manufacturer who is COC-certified.
