On a semi-automatic design and draft of air-conditioning a building by use of macro-language in a personal CAD

Semi-automatic design and draft of air-conditioning a building are performed by using Macro-language in a personal computer. Selections of wall materials and glasses, calculations of interior and perimeter thermal loads, designs of wall structures, capacities of cooling tower and water heater, arrangements of fancoil unit and pipes with their joints are semi-automatically carried out and drafted with and/or without much information given in a conversation-style. Some of the designs and drafts for the two floors having a capacity of 20,593m^3 and 26 rooms in a four-story building are reported and the utility of a personal CAD for air-conditioning a building is discussed.
