10.1 Data Requirements for Selected Building Sub-Systems
The Express-G represe
number of the selected building sub-systems are documented in this Appendix, and the abbreviation AC is often used to denote
For example, the overall Water Supply system can be represented as below in Figure 47, with constituent parts as shown in Figure 48and Figure 49 below.
