I am somewhat confused about calculating the baseline lighting power calculation, Space-By-Space method, with respect to lighting controls.
For example, Table G3.1 states "Lighting shall be modeled having the automatic and manual controls in Section 9.4. For a Conference/Meeting/Multipurpose room the LPD is 1.23 W/ft2. 22.214.171.124.(b) states that a conference room shall have an occupancy sensor. Does this mean that the LPD is reduced by the factor listed in Table G3.2 is 10% for occupancy sensor in buildings greater than 5000 ft2. So would the LPD for the baseline conference room be 1.23 * 0.9 = 1.1?
Thanks for your assistance!
