IEQ 1-4 Flashcards
What does the “E” stand for in IEQ?
Environmental
Name 2 prerequisites in the IEQ Section
- Minimum Indoor Air Quality Performance 2. Environmental Tobacco Smoke Control
What is the intent of Indoor Environmental Quality prerequisite 1?
To prevent the development of indoor air quality problems and contribute to the well- being and comfort of its occupants.
What standard sets the minimum for minimum IAQ performance?
ASHRAE 62-1999 (and approved addenda ASHRAE 62-2001, Appendix H).
What are the design strategies to address minimum IAQ performance?
Identify potential IAQ problems on the site and locate air intakes away from contaminate sources.
What does ETS mean?
Environmental Tobacco Smoke
What are 2 potential ETS requirements?
- Prohibit smoking in building and near entry 2. Designated smoking room that effectively removes ETS from the building
What is IEQ Credit 1 called?
Carbon Dioxide Monitoring
What is the intent of the Carbon Dioxide Monitoring Credit?
Provide capacity for IAQ monitoring to sustain comfort and well being.
How many points are available for Carbon Dioxide Monitoring?
One
What ASHRAE standard discusses CO2 and metabolic rates?
ASHRAE 62-2001, Appendix D
What is the strategy for CO2 monitoring?
CO2 monitoring sensors in HVAC, integrated with the building automation system (BAS)
What is IEQ Credit 2 called?
Ventilation Effectiveness
What is the intent of Ventilation Effectiveness Credit?
Provide fresh air.
How many points are available for Increase Ventilation Effectiveness?
One
What does the E stand for in (Eac) ventilation systems?
Air change Effectiveness
In Ventilation Effectiveness, what value should E be in mechanically ventilated spaces?
Greater or equal to 0.9.
In naturally ventilated spaces, what must be summarized in a table?
Provides effective ventilation for 90% of each zone for at least 95% of hours of occupancy.
What standard sets the E for mechanically ventilated buildings?
ASHRAE 129-1997
How do you design an envelope system to optimize E?
Displacement ventilation, low velocity ventilation, plug flow ventilation, and operable windows.
What is IEQ Credit 3 called?
Construction IAQ Management Plan
What is the intent of Construction IAQ Management Plan Credit?
Prevent indoor air quality problems resulting from the construction/renovation process.
How many points are available for Construction IAQ Management Plan?
Two
During construction, the IAQ Management Plan requires following what standards?
SMACNA IAQ Guideline for Occupied Buildings Under Construction, 1995, Chapter 3.
What are the requirements under Construction IAQ Management Plan?
- Compliance with SMACNA 2. Protection of absorptive material from moisture damage and 3. Replace filtration before occupancy
What Minimum Efficiency Reporting Value (MERV) standard must filtration media adhere to?
13, as determined by ASHRAE 55.2-1999
How long is the flush-out period in Credit EQ3.2
2 weeks (minimum).
What are the 2 options to achieve Construction IAQ Management Plan Credit 3.2?
Flush-out with 100% outside air for 2 weeks or conduct a baseline IAQ test.
What standard applies for a for the baseline IAQ test?
EPA Protocol for Environmental Requirements, for the Research Triangle Park Campus, Section 01445.
What is the strategy for a Construction IAQ Management Plan?
Protect HVAC during construction, control pollutant sources, interrupt pathways for contamination; sequence material installation; 2 week flush-out or test the contaminant levels.
What is IEQ Credit 4 called?
Low-Emitting Materials
How many points are available for Low- Emitting Materials?
Four
What is the intent of Low-Emitting Materials Credit?
Reduce the quantity of indoor air contaminants that are odorous or potentially irritating.
What material does IEQ Credit 4.1 cover?
Adhesives & sealants
What is the standard for IEQ 4.1?
Adhesives: South Coast Air quality Management District Rule #1168; Sealants: Bay Area Air Quality Management District Reg 8, Rule 51
What material does IEQ Credit 4.2 cover?
Paints & coatings
What is the standard for IEQ 4.2?
Green Seal’s Standard GS-11
What material does IEQ Credit 4.3 cover?
Carpet systems
What is the standard for IEQ 4.3?
Carpet & Rug Institute Green Label IAQ Test Program
What material does IEQ Credit 4.4 cover?
Composite wood & agrifiber products
What is the standard for IEQ 4.4?
Products must contain no added urea- formaldehyde resins.
What are the strategies to meet IEQ Credit 4?
Specify low-VOC materials in construction documents. Ensure that VOC limits are clearly stated in each section where adhesives, sealants, paints, coatings, carpet, and composite wood systems are addressed.
