EQ PR1 Minumum indoor air quality |
Meet ASHRAE Standard 62.1-2010 (Ventilation of acceptable indoor air quality) or local equivalent, whichever is stricter. |
|
EQ PR2 Environmental Tobacco Smoke Control |
-prohibit smoking in bldg -profit smoking outside except designated area 25ft away from bldg fenestration -residential indoor smoking ONLY after meeting contamination standards |
|
EQ1 Enhanced Indoor Air Quality standards |
OPT 1 A- entryway systems: install permanent 10 feet along in primary direction of travel; can include grates, grilles, rollout mats B- interior cross contamination prevention: exhaust spaces where hazardous gases are used (garage, housekeeping/laundry, copying, printing) C- filtration: ventilation systems must meet one of following: 1. Min. Efficiency reporting value (MERV) of 13 or more; 2. Class F7 or higher filter performance. D- natural ventilation design calcs: system design employs strategies in CIBSE Applications Manual E- mixed mode design calcs: also adheres to CIBSE mixed mode calculation.
OPT2 additional IAQ strategies A- exterior contamination prevention: minimize entry of pollutants into bldg B- increased ventilation: increase ventilation rates 30% above EQ PR1 C-co2 monitoring: monitor within breathing zone 3-6ft D-additional source control and monitoring |
|
EQ2 Low emitting materials |
Assessed the emissions of BOCs into the building interior (everything within waterproofing membrane) VOC Budget: weighted average calculation to show that the majority of products comply. |
|
EQ3 Construction Indoor Air Management Plan |
Air management that addresses the following: -during construction follow Sheet Metal and AC National Contractors Association -if permanently installed hvac units are used during construction, use MERV 8 filter; replace all filters prior to occupancy -prohibit use of tobacco products and 25ft from entrance |
|
EQ4 Indoor Air Quality Assessment |
OPT 1 Flush out Path 1 before occupancy: 14,000 ft3 / ft2 of outside air Path 2 during occupancy: min of 3,500 ft3 / ft2 prior to occupancy; 14,000 during. OPT 2 Air testing Conduct IAQ testing consistent with EPA protocol in breathing zone 3-6ft |
|
EQ5 Thermal Comfort Meet requirements for tc design & tc control |
THERMAL COMFORT DESIGN OPT 1 ASHRAE standard 55-2004: Design to meet thermal comfort conditions for human occupancy. Environmental factors are temp, thermal radiation, humidity, airspeed. Personal factors are activity, airspeed. or OPT 2 ISO and CEN Standards: Design HVAC system and bldg envelope to meet requirements of ISO 7730 2005 (Ergonomics of Thermal Environment) or CEN Standard EN 152151: 2007 (Indoor Environmental Input Parameters for Design and Assessment of Energy Performance of Bldgs) THERMAL COMFORT CONTROL -provide comfort ctrl for 50% individual spaces; group ctrl for all shared multi-occupant spaces -thermal comfort ctrl for at least one of the following: air temp, radiant temp, air speed, humidity. |
|
EQ6 Interior Lighting |
OPT 1 Lighting control -90% individual occupant spaces provide individual lighting control with at least three lighting levels and/or OPT 2 Lighting quality with characteristics such as: -color rendering index (CRI) of 80 or more -rated life of at least 24,000 hr -indirect lighting |
|
EQ7 Daylight Select one of three options |
OPT 1 & 2 Computer simulation calculation -specific daylight illuminance levels have been achieved via annual computer simulations or OPT 3 Measurement -achieve specific illuminance levels for % of floor area |
|
EQ 8 Quality Views |
-Achieve direct line of sight to outdoors via vision glazing for 75% of floor area. -Areas with views must have two of the following: 1. multiple lines of sight to vision glazing at different directions 90 degrees apart at least 2. views include at least two: flora, fauna, sky; movement; objects 25 ft from exterior 3. unobstructed views located within 3x head height of glazing 4. view factor of 3 or more, defined in "Windows and offices: A study of office worker performance and indoor environment" |
|
EQ9 Acoustic Performance |
Address the following: -HVAC background noise -sound transmission -reverberation time -sound reinforcement / masking system |
|
