Indoor Environmental Quality 15 pointsOption 1 -Mechanically Ventilated Buildings = Active Ventilation

Meet the minimum requirements of ASHRAE 62.1-2004 Sections 4 through 7

(Ventilation for Acceptable Indoor Air Quality) using the ventilation rate procedure

or the applicable local code, whichever is more stringent.

Option 2 - Naturally Ventilated Buildings = Passive Ventilation

Shall comply with ASHRAE 62.1-2004, paragraph 5.1

Option 3 - Both Mechanical & Natural Ventilation = Mixed-mode Ventilation

Shall comply with ASHRAE 62.1-2004, chapter 6

Option 1 - Non Smoking Building

Smoking is prohibited within the buillding

ANDDesignated exterior smoking areas have been located at least 25ft away from

entries, outdoor air intakes and operable windows.

Option 2 - Designated Smoking Rooms

Smoking is prohibited within the buillding except in designated smoking areas

ANDDesignated exterior smoking areas have been located at least 25ft away from

entries, outdoor air intakes and operable windows

AND the project has provided one or more designated smoking rooms. The

smoking rooms are designed to be directly exhausted to the outdoors with no re-

circulation of ETS-containing air to the non-smoking area of the building, and

enclosed with impermeable deck-to-deck partitions and operated at a negative

pressure compared with the surrounding spaces of at least an average of 5Pa

(0.02in wg) & with a minimum of 1 Pa (0.004in wg) when the door(s) to the

smoking room are closed

ANDThe performance of the smoking room differential air pressures has been

verified by conductiong 15 minutes of measurement, with a minimum of one

measurement every 10 seconds, of the differential pressure in the smoking room

with respect to each adjacent area and in each adjacent vertical chase with the

doors to the smoking room closed. The testing was conducted with each space

configured for worst case conditions of transport of air from the smoking rooms to

adjacent spaces with the smoking rooms'doors closed to the adjacent spaces.

Option 3 - Residential Compliance

Smoking is prohibited in all commom areas of the buillding

AND Designated exterior smoking areas have been located at least 25ft away from

entries, outdoor air intakes and operable windows.

between units by sealing penetrations in walls, ceilings, and floors in the

residential units, and by sealing vertical chased adjacent to the units. In addition,all doors in the residential units leading to common hallways shall be weather-

stripped to minimize air leakage into the hallway. If the common hallways are

pressurized with respect to the residential units then doors in the residential units

leading to the common hallways need not be weather-stripped provided that the

positive differential pressure is demonstrated as in Option 2.

Option 1 - Mechanically Ventilated Spaces

an alarm when the conditions vary by 10% or more from setpoint, via either a

building automation system alarm to the building operator or via a visual or

audible alert to the building occupants.

CO2 monitoring locations shall be between 3ft & 6ft above the floor

* for each mechanical ventilation system serving non-densely occupied spaces,

provide a direct outdoor airflow measurement device capable of measuring the

minimum outdoor airflow rate with an accuracy of 15% of the design minimum

outdoor air rate, as defined by ASHRAE 62.1-2004

-

Option 2 - Naturally Ventilated Spaces

The project has been designed to comply with the requirements for location and

size of window openings per ASHRAE Standard 62.1-2004, Section 5.1.

Monitor CO2 concentrations within all naturally ventilated spaces.CO2 monitoring shall be located within the room between 3 ft & 6 ft above the

floor.

Option 1 -Mechanically Ventilated Spaces

Increase breathing zone outdoor air ventilation rates to all occupied spaces by at

least 30% above the minimum rates required by ASHRAE 62.1-2004 as determined

by EQ-p1

Option 2 - Naturally Ventilated Spaces

Design natural ventilation systems for occupied spaces to meet the

recommendations set forth in the Carbon Trust Good Practice Guide 237 [1998].
