USGBC LEED-AP-BD+C Dumps Questions Answers

To achieve the Sustainable Sites Credit, Light Pollution Reduction, Option 1. BUG Rating Method, projects must demonstrate that all luminaires meet acceptable fixture ratings for the project’s Model Lighting Ordnance (MLO) lighting zone. The MLO lighting zone is determined by the site-specific characteristics and the definitions provided in the IES/IDA MLO User Guide1. The fixture ratings are based on the backlight-uplight-glare (BUG) system, which measures the amount of light emitted in different directions by a luminaire, as defined in IES TM-15-11, Addendum A2. The maximum allowable ratings for each lighting zone are given in Table 1 of the credit language3. References: IES/IDA MLO User Guide; IES TM-15-11, Addendum A; Light pollution reduction

An energy meter must be installed for hot water at the main service point for the project to meet the requirements for Energy and Atmosphere Prerequisite, Building-Level Energy Metering. According to the LEED v4 BD+C Reference Guide, this prerequisite requires that “all energy sources used by the building must be metered or submetered” 1. The hot water from the central utility plant is an energy source used by the building, even if it is not directly paid by the office. Therefore, it must be metered at the point where it enters the building. The other options are incorrect because natural gas is not an energy source used by the building in this case, and the flat fee or the ownership of the energy source do not exempt the project from the metering requirement.References: LEED v4 BD+C Reference Guide, Energy and Atmosphere Category, EAp Building-Level Energy Metering, page 569.
