Explanation / Answer

answer

1....option (c)(d) is correct

Lights create heat.  Therefore, reducing lighting power reduces the heat generated from those lights

which then reduces the cooling load required to cool the building.The Reducing lights does not reduce the

heating requirements of the building nor does it necessarily provide for more control.  Occasionally,

projects that lower the lighting power density, must actually increase heating loads and sacrifice

lighting controllability in return.

2...option (c) is correct

HFCs are better than HCFCs, which are better than CFCs which are the worst.because it deplition of ozone layer.

3....option (b) (e) is correct

Per the''LEED''Reference Manuals and the GreenStep Study Guide, the Indoor Water Efficiency

calculations are based on the number of people in the building, not the number of fixtures.  It makes

sense if you think about it:  A building with 100 toilets and only 2 people, would only use as much

water as is required for 2 people, not for 100 toilets.  The five fixture type that are included as part of

this calculation are: water closets (toilets), urinals, lavatory sinks, showers and kitchen faucets.  While

projects may potentially earn points for efficient dishwashers, it would not be under the Indoor Water

Use Reduction credit.

4....option (b) (c) is correct

GBCI will not officially accept or approve Design Phase credits until the design strategies have been

implemented and construction is completed.  In the meantime, the design review response issued for

an allowable approach would be 'Anticipated'.This information becomes from the Introduction section of the

LEED Reference Manuals as well as GreenStep's Study Guide.

5.....option (c)

The standard for carpets is the Green Label Plus Program, not to be confused with the standard for

carpet cushions which is the Green Label Program. so that This information comes from the IEQ credit that

addresses Low Emitting Materials - Carpet & Flooring Systems and is also covered in GreenStep's

Study Guide.
