I have a question about #201 on page 3-7, Ballast Practice Exam;
#201) Which of the following factors increase a building's efficiency?
(A) a central mechanical plant
(B) small rooms
(C) a single-story building
(D) many offices requiring windows
the answer is (C). it says consultants' choices can also have a significant impact on efficiency;.....Furthermore, programs that require large rooms, specify flexible requirements regarding adjacencies and/or windows, and have a low population as defined by the code (requiring smaller means of egress) tend to be more efficient. A designer can further increase the efficiency of a building by limiting the design to one story with a central core and by using double-loaded corridors.
a) large rooms require bigger means of egress compared to small rooms (if occupancy group is the same), and I don't understand how larger rooms increase efficiency.
b) how windows impact efficiency?
c) I understand a central core and double-loaded corridors can increase efficiency, but how can only the fact the building is single story increase efficiency?
Thank you in advance!
