LEED-AP-BD+C Exam Dumps : LEED AP Building Design + Construction (LEED AP BD+C)

Plug-in task lighting is considered as furniture and is not included in the installed lighting power calculations for Energy and Atmosphere Prerequisite, Minimum Energy Performance. It is also not required to comply with the lighting control requirements of ASHRAE 90.1-2010. However, it can be used to satisfy the individual control requirement of Indoor Environmental Quality Credit, Interior Lighting, Option 1. References:

The average flush rate for a dual flush toilet is calculated by weighting the high and low flush rates according to the frequency of use. According to the LEED Reference Guide for Building Design and Construction1, the frequency of use for male and female occupants is assumed to be as follows:

Male full flush: 1 time per day

Female full flush: 1 time per day

Male low flush: 2 times per day

Female low flush: 2 times per day

Therefore, the average flush rate for a dual flush toilet with a high flush rate of 1.6 gpf (6 lpf) and a low flush rate of 1.05 gpf (4 lpf) is:

6(1×1.6)+(1×1.6)+(2×1.05)+(2×1.05)​=1.19 gpf(4.5 lpf)

Using plug-in devices can affect the energy performance of the building, which is one of the criteria for achieving Indoor Environmental Quality Credit. Thermal Comfort. The LEED v4 Reference Guide for Building Design and Construction states that "the project team must demonstrate that the proposed design meets the minimum energy performance requirements of ASHRAE Standard 90.1-2010, Appendix G, with errata"1. Plug-in devices are considered as part of the process loads in the energy model, and they can increase the energy consumption and demand of the building. Therefore, the project team must account for the plug-in devices in the energy model and ensure that the proposed design meets or exceeds the baseline performance rating.
