Indoor air quality management design strategies

- [Instructor] The LEED rating system…ensures a minimum indoor air quality performance…by mandating minimum ventilation standards.…LEED prerequisite minimum indoor air quality performance…ensures that all occupied spaces are ventilated…with fresh air at all times,…and wide assured by meeting the requirements…of ASHRAE Standard 62.1.…For the LEED Green social exam,…you need to know that ASHRAE Standard 62.1…applies to ventilation, strategy, and design.…Project teams can earn points if they…increase the ventilation rates by at least 30 percent…above the minimum rate required by the prerequisite.…

By doing that, the project teams need to pay attention…to trade-offs for increased ventilation.…For example, bringing an increased amount…of outside air to indoor spaces can result…in cooling or heating more air…and increases energy consumption.…There's another trade-off to keep in mind…if the outdoor air quality is not good.…In that case, air filters at supply side…of the mechanical equipment should be carefully considered.…
