<p>Dear All,<br>
<br>
We are working on residential building in Istanbul/Turkey. The
building is heated and cooled by radiators and split AC
respectively. Residential units are not include any fan for
outdoor air supply. All residential units are natural ventilated.
<br>
<br>
We got following comment after design final submission : <br>
<br>
"IEQp1: Minimum Indoor Air Quality Performance indicates that
natural ventilation is designed for residential spaces. However,
it is unclear whether the heating and cooling loads associated
with ventilating the building have been accounted for in the
energy analysis. It is unclear if the residential fans serving the
dwelling units are currently modeled as cycling on to meet the
loads when there is a call for heating and cooling. Most
simulation software models zero ventilation when the fans are
cycled off. Therefore, if the fans are modeled as cycling to meet
the loads, the Baseline and Proposed Case energy model should be
revised to account for the anticipated ventilation loads
anticipated when the fans are cycled off. (e.g. infiltration
should be increased equally in both cases to assume that a certain
portion of the windows are open to meet ventilation loads). If the
HVAC system serving residential spaces are accounted for when the
fans cycle off. Provide sample inputs for the Baseline and
Proposed Case dokumentating how the ventilation was accounted for,
and confirming that the ventilation and infiltration have been
modeled identically in the Baseline and Proposed Case models."<br>
<br>
We did not understand reviewers comment about fans. Because, our
natural ventilated dwelling units are not include any supply
outdoor air fan. Is there something we do not understand? <br>
<br>
We are planning to do folllowing:<br>
<br>
We will add same infiltration rate all day long on both Baseline
and Propsod Case amount of ASHRAE 62.1-2007 Minimum Outdoor Air
Requirements.<br>
<br>
Is our plan proper? Will our submission be accepted? <br>
<br>
