Private lavatory faucets are eligible for a WaterSense label, provided they meet EPA’s specifications for water efficiency and performance, and are backed by independent, third-party certification. Tankless toilets, waterless urinals, and public lavatory faucets are not eligible for a WaterSense label because they are not included in the product categories that WaterSense covers. WaterSense currently labels products in the following categories: tank-type toilets, water-using urinals, private lavatory faucets, showerheads, irrigation controllers, spray sprinkler bodies, and pre-rinse spray valves.References:

To comply with Indoor Environmental Quality Credit, Thermal Comfort, the standard that needs to be followed is ASHRAE 55-2010, Thermal Environmental Conditions for Human Occupancy, with errata or a local equivalent1.This standard specifies the combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space2.The standard also provides methods for measuring and evaluating thermal comfort, as well as guidance for design, operation, and maintenance of thermal comfort systems2.References:Thermal comfort;ASHRAE 55-2010

This option requires the project to provide safe collection, storage, and disposal for electronic waste, such as computers, monitors, printers, and batteries, because it contains hazardous materials that can harm human health and the environment if not handled properly1. Electronic waste can be recycled or reused by certified e-waste recyclers or manufacturers2.

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.
