Some of the design strategies a project team is proposing include daylighting, drip
irrigation, photovoltaic systems, optimizing building orientation, and providing high
albedo parking surfaces. The building owner would like to offset some of the higher costs
for the sustainable design strategies being proposed for the building project. What could
the design team propose to provide the greatest reduction to the owner’s operating costs?
A: Increasing ventilation
B: Implementing stormwater collection
C: Purchasing RECs
D: Installing net metering

参考答案: D

本题解释:
Notes:
Net metering is a billing and metering arrangement that lets buildings with on-site renewable
energy redirect excess energy to the local power grid. This excess electricity can then be
deducted from what the building draws from the grid for electricity use.
Increased ventilation can increase costs, because more air then needs to be distributed in the
building.
RECs are for green power and would not lower costs as much as net metering.
Stormwater collection will help reduce water consumption for irrigation. However water is very
cheap relative to electricity and the offset in costs would thus be less than for net metering.
Additionally because drip irrigation is already being used, a savings of 30%-50% in water use
already exists. Less water also requires less energy to distribute.
