# Criterion 11: Achieving indoor comfort requirements (visual/ thermal/ acoustic)

- How should the window height be calculated in the day lit zone area calculations in Criterion 13, GRIHA Version 3?
- Does GRIHA allow for mutual shading from neighboring buildings and trees?
- Can the SHGC value of a residential building be taken for a hostel building?
- Is complying with U-values mandatory in GRIHA?
- How can the multiplication factor for an overhang and a vertical fin be calculated?
- With reference to criterion 13, GRIHA Version 3, while calculating daylight area and daylight factor, should the kitchen be considered as well? Is kitchen considered as regularly occupied area or is exempted?
- For SHGC calculation in criterion 13 (GRIHA Version 3), the northern facade is at an angle so how shall we determine the direction of the fenestration.
- What is the u value requirement for glazing under GRIHA version 3?
- How can the daylight analysis be performed for a core and shell project with no interior layouts?
- Kindly share the correct methodology to carry out SHGC calculation for an inclined glazed façade in criterion 13 (GRIHA Version 3). How shall the shading projection be calculated?
- Do the exterior windows in non-livable areas such as store room, toilet, etc. need to meet the SHGC/shading criteria as per criterion 13 (GRIHA Version 3)?
- The Day light Factor for Laboratories is specified as 2.5-3.8 in in criterion 13 (GRIHA Version 3). Similarly, Classrooms have Daylight Factor specified as 1.9-3.8. Is this a range?
- What should be considered as recommended Daylight Factor for meeting rooms and auditoriums in criterion 13 (GRIHA Version 3)?
- What daylight factor should be considered for the following spaces in criterion 13 (GRIHA Version 3): 1. Hostel rooms 2. Guest rooms 3. Community dining area
- Is it necessary to meet thermal comfort conditions of criterion 14(GRIHA Version 3) in kitchens?
- I have calculated the daylight areas according to table 13.6 in criterion 13 (GRIHA Version 3) using AutoCAD. How can I input the data into the online daylight calculator?
- What is the correct method of calculating daylight factor?
- Is “Overcast Sky” considered as design sky condition while simulating for indoor Illuminance (lux) in criterion 13 (GRIHA Version 3)?
- What time, date and month should be considered while simulating for indoor illuminance in criterion 13 (GRIHA Version 3)?
- If daylight penetration is more than 2H (depth of day lighted zone) and room depth is more than the day lighted zone’s depth, can we consider increased depth of the day lighted zone (more than 2H) ?
- Is energy calculation done in Visual DOE /eQuest software enough to demonstrate thermal comfort compliance?
- How can we prove compliance for natural ventilated spaces in criterion 14 (GRIHA Version 3)?
- What all spaces need to comply (Regular & Non-regular) for thermal comfort in criterion 14 (GRIHA Version 3)? Do service areas also need to comply?
- What all simulation software tools can be used for showing thermal comfort compliance in criterion 14 (GRIHA Version 3)?
- Will these areas come under daylight areas for calculations in criterion 13 (GRIHA Version 3)? 1. Canteen 2. Restaurant 3. Shops 4. Pantry 5. Dining room
- Is it mandatory to meet SHGC compliance for display windows in a mall? How can compliance with day lit zone and day light factor be demonstrated in a mall?
- What documents are needed to show compliance with thermal comfort in criterion 14 (GRIHA Version 03)?
