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.

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].
