Cx stands for
Commissioning process
Commissioning
Process of verifying and documenting that a building and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the OPR.
Alternative energy sources
Wind, biomass, solar, geothermal, hydropower (rivers), tidal (waves)
ROI

commingled waste
building waste streams that are combined on the project site and hauled away for sorting into recyclable streams. Also known as single-stream recycling.
dedicated storage
a designated area in a building space or a central facility that is sized and allocated for a specific task, such as the collection of recyclable waste. Signage often indicates the type of recyclable waste stored there. Some waste streams, such as mercury-based light bulbs, sensitive paper documents, biomedical waste, or batteries, may require particular handling or disposal methods. Consult the municipality’s safe storage and disposal procedures or use
electronic waste
