What are the best design strategies for improving indoor air quality during operations and maintenance of a building?(choose 2)
A: Use air filters with high minimum efficiency reporting value (MERV) ratings
B: Use natural refrigerants
C: Use soft surfaces on the interiors
D: Orient the building for optimal sun exposure
E: Increase the ventilation in the building

参考答案: AE

本题解释:
MERV ratings are a standard comparison of the efficiency of an air filter. The MERV scale ranges from 1 (least efficient) to 16 (most efficient), and measures a filter\'s ability remove particles from 3 to 10 microns in size. The ratings were developed by ASHRAE;The type of refrigerant does not directly impact the particulates in the air;Soft surfaces are good for acoustic design, not air quality;Building orientation can impact the particulates entering the building due to the direction the wind blows. However it isn\'t as big of a factor as the air filters used; Additional outdoor air can be provided in the building. This is a common trade-off though - when increasing the ventilation for a mechanical system the energy use of the building goes up.

New Construction projects can earn credit for Increased Ventilation. In milder climates Increased Ventilation can still be accomplished with natural ventilation through proper design of air flows through the building.
