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

• Are circulation spaces like corridor, lift lobby, entrance hall and other spaces like waiting areas, reception area in an office building included in daylight calculations?
• Are thermal comfort conditions for non-air-conditioned spaces same in both GRIHA V3 and GRIHA 2015?
• If a building is not oriented to any true direction, then how the orientation should be considered for Criterion 13?
• What is the maximum SHGC limit for a residential development in composite climate
• Is the noise measurement an instantaneous measurement?
• What is the right method to show compliance with 25% mandatory day lighting in GRIHA Rating?
• Can Canteen building and Auditorium be exempted from the mandatory daylight requirement as per GRIHA v3 criteria 13
• Can 'Berkeley tool for thermal comfort' based on ASHRAE Standard 55, 2013 be used to demonstrate compliance with the requirement for thermal comfort (conditioned spaces) under Criteria 11
• Can some task specific spaces in hospitals be exempted from the daylight calculation?
• What is the required procedure for noise level testing at the site
• Please provide list of agencies for conducting noise audit?
• Is it required to include doctor consultation room/examination room in daylight factor calculation/daylight simulation?
• Is any relaxation available in the SHGC of skylights?
• Can a GRIHA registered project comply with GRIHA criterion 13, by using films on fenestrations without shading device and with high SHGC glass?
• In GRIHA version 2015, which of the following: Ecotect or SP41 (handbook) or SEC, should be used as the source for Annual Solar Insolation?
• Which simulation software can be used to calculate VLT, U value and other such parameters of a high performance glass with sun control film?
• Windows of which areas are exempt from meeting SHGC requirements?
• If BIPV is proposed for Southern walls, then will it be treated as transparent or opaque for WWR calculation?
• As the building is going to be occupied only during early morning and late evening, the effect of increasing SHGC is insignificant on the EPI. So how can we demonstrate compliance?
• What method of day lighting analysis should be followed if a project has 3 typical towers? Specifically, if there is a notable difference between the day lit area of all three towers.
• What is the corresponding temperature range for the 70% relative humidity range in non- conditioned areas?
• Where can we find the fresh air requirements for all conditioned zones to comply with NBC 2005?
• How can a builder make sure that the tenants follow GRIHA requirements in their leased apartments?
• Kindly confirm if GRIHA accepts Autodesk ECOTECT software for Hourly calculations of Thermal Comfort compliance and Energy Modeling & Simulation in Criterion 14 (GRIHA Version 3).
• Are dual switch systems with manual on/off switches and dual lighting circuits accepted as lighting controls? Will the project satisfy ECBC requirements and be GRIHA compliant?
• Are day light sensors acceptable as lighting controls and will they satisfy ECBC norms and GRIHA requirements?
• If the SHGC value for a particular façade is little less than the other facades, then is it possible to ignore the value and follow any of the remaining façade values for the whole building?
• Air-conditioned buildings need to have ACH (air changes) requirements based on the NBC. Is it mandatory for the non-air-conditioned buildings also to meet the ACH as recommended by NBC?
• Is it required to achieve lux level values as per NBC for the whole office space as an average or just under the light fixtures where the work stations will be placed?
• Can a project show compliance with Criterion 13, GRIHA Version 3 requirements by submitting average WWR value?
