USGBC LEED-AP-BD+C Dumps Questions Answers

The renewable energy option is economically feasible if the present value of the utility cost savings over the lifetime of the system is greater than or equal to the present value of the higher initial cost of the system. This means that the system will pay for itself and generate net savings in the long run. The utility cost savings depend on the amount of energy produced by the solar thermal panel, the price of natural gas, and the inflation rate. The higher initial cost depends on the size, type, and installation of the solar thermal panel.

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.

According to the LEED Reference Guide for Building Design and Construction1, the Location and Transportation Credit, Bicycle Facilities, requires the project to provide short-term and long-term bicycle storage and a functional entry or bicycle storage within 200 yards of a bicycle network. The bicycle network is defined as any one of the following:

Off-street bicycle paths or on-street bicycle lanes that are physically marked and separated from motor traffic

Streets designed for a target speed of 25 mph (40 km/h) or less, with traffic calming features such as curb extensions, speed humps, raised crossings, narrowed traffic lanes, median islands, tight corner radii, roundabouts, or landscaping

Streets with a legal speed limit of 25 mph (40 km/h) or less that connect to a larger bicycle network

Therefore, among the given options, only slow speed roadways can define a bicycle network, as they can provide a safer and more comfortable environment for cyclists. One-way streets, bike share, and traffic lights are not sufficient to define a bicycle network, as they do not necessarily indicate the presence of bicycle paths, lanes, or low-speed streets.
