The LEED project has a main entrance and two service entrances in an alley behind the building. Which entrances need non-smoking signage and at what maximum distance from the door(s) can the non-smoking signage be posted?
Answer(s): C
According to the LEED v4 Reference Guide for Building Design and Construction, no smoking signage must be placed within 10 feet (3 meters) of every building entrance, except for alarmed emergency exits. This applies to both the main entrance and the service entrances, regardless of their location or frequency of use. The signage is intended to communicate the no-smoking policy to occupants and visitors and prevent environmental tobacco smoke from entering the building.

A school wants to incorporate natural daylighting in classrooms on all sides of the building. What can the project design team explain to the school district about how this strategy will affect the operational energy cost?
Answer(s): B
Natural daylighting can reduce the electricity use for artificial lighting, which is one of the major components of operational energy cost for buildings. By having the lights off or dimmed when sufficient daylight is available, the project can save energy and money. The other options are not necessarily true or relevant for natural daylighting. Heat gain and passive solar heating depend on the orientation, shading, and insulation of the windows, not just the amount of daylight. Reduction in lighting fixture use may reduce re-lamping, but that is not a significant factor in operational energy cost compared to electricity use.

Which item is included in the reuse calculation for Materials and Resources Credit, Building Life-Cycle Impact Reduction?
Answer(s): A
The reuse calculation for MR Credit Building Life-Cycle Impact Reduction includes the surface area of structural elements that are reused in place or salvaged and reinstalled, such as floor decking, columns, beams, and roof decking. Exterior glazing and plumbing fixtures are not considered structural elements and are not included in the reuse calculation. Asbestos insulation is a hazardous material that should be removed and disposed of properly, not reused.

A project in a cold climate does not want a highly reflective roof because they want the heat absorption. How can this project comply with Sustainable Sites Credit, Heat Island Reduction?
The credit may be achieved by using nonroof measures only, such as shading, paving, and vegetation, to reduce the heat island effect on the site. The credit does not require a highly reflective roof for all projects, but allows for flexibility and trade-offs depending on the climate and design conditions. The project can use the Heat Island Reduction 1 to demonstrate compliance with the credit requirements. The credit is feasible and applicable for this project, and does not need an alternative compliance path.

What is the basis of energy consumption in determining the percentage of green power or carbon offsets?
The basis of energy consumption in determining the percentage of green power or carbon offsets is the quantity of energy used by the project, measured in kilowatt-hours (kWh) or British thermal units (Btu). Green power is electricity generated from renewable sources, such as solar, wind, hydro, biomass, or geothermal. Carbon offsets are reductions or removals of greenhouse gas emissions from a project or activity that compensates for the emissions from another source. According to the LEED Reference Guide for Building Design and Construction1, the Energy and Atmosphere Credit, Green Power and Carbon Offsets, requires the project to engage in a contract for qualified resources that meet the following requirements:The contract term is at least five years.The green power or carbon offsets are based on the quantity of energy consumed by the building. The green power is Green-e Energy certified or the equivalent. The carbon offsets are Green-e Climate certified, Verified Carbon Standard certified, Gold Standard certified, or the equivalent.
