I get puzzled by the code requirement of Title 24 2016 Sec 141.0(b)(2) J:
[FONT="]Luminaire component modifications in place that include replacing the ballasts or drivers and the associated lamps in the luminaire, permanently changing the light source of the luminaire, or changing the optical system of the luminaire, where 70 or more existing luminaires are modified either on any single floor of a building or, where multiple tenants inhabit the same floor, in any single tenant space, in any single year, shall not prevent or disable the operation of any multi-level, shut-off, or daylighting controls, and shall:[/FONT]
[FONT="][FONT=HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif]i. Meet the lighting power allowance in Section 140.6 and comply with Table 141.0-E; or[/FONT][/FONT]
[FONT="][FONT=HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif]ii. In office, retail, and hotel occupancies have at least 50 percent, and in all other occupancies have at least 35 percent, lower rated power at full light output as compared to the original luminaires prior to being modified, and meet the requirements of Sections 130.1(a)1, 2, and 3, 130.1(c)1A through C, 130.1(c)2, 130.1(c)3, 130.1(c)4, 130.1(c)5, 130.1(c)6A, and for parking garages 130.1(c)7B
For example, if there is a office TI project, the total area might be 1000 sqft. Our scope is only a 200 sqft office.
My questions are as follows:
1. Do we need to provide multi-lighting control for this 200 sqft office? My understanding is that we need to meet Title 24 requirement for this area and provide multi-lighting control as the total area is more than 100 sqft.
2. Do we also need to replace lamps for the rest of the buildings to meet Title 24 requirement?
My understanding is that as we only replace less than 70 luminaires in the 200 sqft office, we do not need to replace lamps [FONT=HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif]for the rest of the buildings to meet Title 24 requirement.
[/FONT] Is my understanding correct?
