| TQ165 Sliding door for ventilation | v4.1 | August 2022 | EHC | Link | |
|
Approved Ruling: It is a requirement for habitable spaces to have a reliable and practical means of ventilation and in this case, the project seeks to use the intermittent extract pathway which means reliance on passive ventilation for habitable spaces. Therefore, having the slider as the only source of ventilation can be problematic for a space that is a kitchen, dining, and living area. Because while the slider can be very useful during the day in the summer when the space is in use and/or occupied this may not be the casein the winter. Furthermore, leaving a sliding door open at night in any dwelling raises security concerns. In the case of a care/retirement facility, it can leave both staff and residents feeling unsafe. Hence, the slider is likely to be closed. Thus, NZGBC advises the project to seek alternative means of compliance by considering a ranch slider with an awning window. This also gives building occupants/users control over their space. |
