SITE AUDIT

33
How does ADaRSH help the project management team to check that the site work is in compliance with GRIHA criteria?
AdaRSH conducts 3 mandatory site audits during the construction period of the project. It provides a link between the evaluators and the site construction practices. Also it helps to keep a check of the site construction activity and quality. Generally, as a mandatory procedure 3 site visits are linked with the construction procedure and time line for the project. However, the number of site visits can be increased if a project needs more attention and hand holding to comply with GRIHA criterions.
34
When is the site audit conducted?
1st site visit is proposed at the time of the foundation building process of the project. This initial period is crucial for checking the green compliance of the project.

2nd site visit is proposed when the superstructure of the project is almost complete.

3rd site visit is the final site visit and conducted when the building is almost complete to check the installation of various systems on site as specified in the documents.
35
Who conducts the site audit?
The site audit is conducted by ADaRSH.

No. The entire documentation has to be submitted together and cannot be submitted in parts.
41
What is the evaluation process?
The building is evaluated for GRIHA compliance in a three-tier process.

The GRIHA team conducts the first review the mandatory criteria and may reject a project in the event of non-compliance with mandatory criteria. The team then checks the documentation submitted for the optional criteria. The checking is done by the GRIHA team to ensure that all templates and drawings are filled-in and to ensure that the documentation is complete in all respects (for the attempted criteria). All documents are checked and vetted through the appraisal process as outlined by GRIHA.
The GRIHA team compiles the first evaluation report and sends to the client. The client is required to resubmit details as requested for by the Secretariat in the first evaluation report. The documentation is then sent to the GRIHA evaluators comprising of renowned sector experts from landscape architecture, lighting and HVAC design, renewable energy, water and waste management, and building materials.
The evaluators vet the documentation and independently review the documents for the award of points. The evaluators award provisional points (if documentation is in order as per his/her evaluation) and also comment on specific criteria, if need be. The evaluation report is sent to the project proponent to review the same and, if desired, take steps to increase the score. The report elaborates on the results of the evaluation committee along with its comments. The report also lists the criteria for which the documentation is incomplete/inadequate/inconsistent, detailing all the required information.
The client is allocated one month to resubmit the document with necessary modifications. The resubmitted report should comprise only of additional documents/information desired in the evaluation report, which shall again be put through the vetting process as described above.
The evaluation committee shall then award the final score, which shall be presented to an advisory committee comprising of eminent personalities and renowned professionals in the field for approval and award of rating.
42
What is the duration of the evaluation process?
The evaluation process is a six week long process at the minimum. However, it may extend depending on the time taken by the client to re-submit information requested by ADaRSH / GRIHA Evaluator.
43

The documents are uploaded criterion wise on the internet portal available to the consultant appointed by the client.
44
Who is an evaluator?
An evaluator is a third party professional who is assigned the responsibility of evaluating documents.
45
How can one become a GRIHA Evaluator / GRIHA Trainer?
ADaRSH conducts 3 days Evaluator and Trainers programme across the country. During this programme, participants can take an evaluator or trainer exam.

PROVISIONAL RATING

46
What is GRIHA provisional rating?
The provisional GRIHA Rating is awarded after complete evaluation of project documentation submitted by the project proponents. The final rating is awarded after the building is fully commissioned as per the design intent and operational for at least 12 months. An energy audit report by an energy auditor accredited by the Bureau of Energy Efficiency needs to be submitted to ADaRSH to achieve the final rating.

ENERGY AUDIT

47
When is the energy audit conducted?

CRITERIA

Criteria 5: Reduce hard paving on site

52
Do you consider precast concrete paver interlocking tiles laid on pathways and approach roads under pervious paving or hard paving?
Precast concrete inter locking pavers would be considered as hard paving.

Criteria 11: Reduce building water use

53
During monsoon, the potable water demand could be met by rainwater harvesting. Please clarify whether peak rainfall would be considred or the average rainfall. How will the rainwater tank size be calculated?
For rain water storage and harvesting calculations please refer following guidelines -
For storage - The calculation should be done on daily average and proposed storage should have a facility to store minimum of 2 days for daily average rainfall. There should be facility of segregating first flush from the stored rain water.
For harvesting - The calculation should be done on hourly peak and proposed harvesting sizing should be design on the percolation capacity of the soil.

Criteria 13: Optimise building design to reduce conventional energy demand

54
What is the u value requirement for glazing under GRIHA version 3? When the building is stimulated with a glazing of SHGC - 0.45 in Resbuild India, the percentage savings decrease from 41% to 38% because the base case SHGC is 0.25.
As per GRIHA version 3, there is no mandatory requirement of U value for glazing. However it is a good practice to use low U value glazing material to avoid heat gain inside the building. Percentage reduction shown in toolkit is for a reference building which software automatically assumes based on type of building and climate. However this saving is not GRIHA saving since benchmark EPI for GRIHA is different, and hence it is required to manually calculate the saving for GRIHA consideration.
55
Can you kindly confirm whether GRIHA requires a project to achieve the 300 lux for the whole space as an average or under the light fixtures where the workstations would be placed?
The space may have varying average lux levels. However, the average lux level in each working plane/zone must adhere to the NBC 2005 levels. Therefore, the office desks should have at least 300 lux level as average and adjoining public area may have 200 lux level as average. Each activity area must meet their respective NBC 2005 lux level and the analysis and documentation will have to be done in that manner. Otherwise, in case of lighting level calculation being done for the entire space, the average lux level must satisfy the space with the highest threshold requirement.
56
Can the base case be altered to reflect correct savings?
Base case parameters cannot be changed in the software. But different variant can be created and percentage saving between each variant can be looked upon. Please note that as per GRIHA version 3, EPI values can be calculated by using this tool kit by creating design case variant and then manually calculating percentage reduction over benchmark EPI as given in version 3.
57
Can you clarify about the height element in the formula to calculate daylight coverage?
In GRIHA, the day lit zone area calculation methodology is the same as described in ECBC. AS per ECBC, for calculation of day lit zone, the window height to be considered only for day lit zone calculation is the height of the lintel, of the window, from the floor.

Criteria 14: Optimise energy performance of building within specific comfort limits

58
The thermal comfort criteria requirement is that 60% of the occupied hours of the building should have an RH of less than 70%. This 70% RH is at what indoor temperature? The RH should ideally relate to an indoor temperature to define comfort conditions. Please provide more clarification on the same.
As per NBC 2005, GRIHA requires for indoor temperature and relative humidity to be below 33 degree Centigrade at 70% RH for at least 60% of total occupied hours for Warm and Humid climates. Please refer to GRIHA Manual Volume 3 for further details on the same.
59
Can you please clarify on U value constraint of GRIHA?
U value for the glass is not a mandatory requirement of GRIHA.

Criteria 15: Utilisation of fly-ash in building structure

60
This is regarding clarification on GRIHA C-15 which is about utilization of fly ash in building structure. However, it would be more convenient to use ground granulated blast furnace slag. Is it acceptable?
Yes it is acceptable. Please ensure that the proportions meet GRIHA requirements.
61
There is an ambiguity with reference to GRIHA Manual, 15.3.2. Please clarify the same.
The calculation, for Appraisal 15.3.2 need to be done based on total volume of fly ash or any BIS approved waste in building blocks. The calculations are to be done against total volume of materials that have been used to construct the walls.

GENERAL

65
What is SVAGRIHA?
ADaRSH in association with TERI has developed a new rating system, SVAGRIHA (Simple Versatile Affordable GRIHA), for small projects with built-up area less than 2500 sq.m. This is a design-cum-rating system comprising of 14 criteria. Therefore, it assists the projects to design as well as rate the green building simultaneously.
With respect to the same, you may register your project with SVAGRIHA for the rating.
Please follow the link for more information. You may also contact us for the same.
66
Please share the details of the registration and certification process of the SVAGRIHA rating system. Can you please clarify if standalone structures, such as a clubhouse in a residential development register for this certification?
Yes, the standalone building in this case can get registered in SVAGRIHA. You may fill up the SVAGRIHA registration form on our website to start the process. Once we receive the completed form, we will get in touch with you for further information and process of the same. The clubhouse in the residential development, can register for this rating.

Please follow the following link to the SVAGRIHA registration form and information on the GRIHA website:

CRITERIA

Criteria 1: Reduce exposed, hard paved surface on site and maintain native vegetation cover on site

67
Is artificial water body counted into softscape area in landscape calculations under SVAGRIHA?
Water bodies are not counted into softscape area in landscape calculations.

Criteria 5: Thermal efficiency of building envelope

68
If, LPD, EPD, Occupancy are also considered, can we take diversity factor into consideration for calculation?
The calculation formats have already been prepared. Request you to please share the data so that the analysis can be done.
69
Based on time of the day or season, the amount of heat gain from building envelope changes as a result the threshold changes. Please confirm for which date and month this needs to be calculated?
The calculation formats have already been prepared. Request you to please share the data so that the analysis can be done.

Criteria 6: Use of energy efficient appliances

70
Is there a need to install separate energy meter for each electrical equipment?
SVAGRIHA does not have such a requirement.

GRIHA LD

71
Will the client have to pay again the same fee during phase 2 GRIHA LD certification? The MEP design is being finalized for phase 1 only, but landscape, roads etc. is for the entire master site.
There is a tentative phase 2 plan but we are not focusing on that now. It is hard to exactly isolate phase 1 area as it is an educational campus.
No, the registration fees for phase 2 will be revised. The phase 2 will get registered separately at a later date. Registration fees of phase 2 will have to be paid at that point. The project will not be required to go for master plan rating again.
72
If a township is awarded a GRIHA - LD rating, do the buildings have to be certified separately as well?
If yes, is the process separate or simultaneous? Will all the documentation have to be done again or the overlapping criteria can be skipped, as most of the points in the LD rating are applicable to buildings?
It is optional for individual buildings, in a GRIHA LD rated neighbourhood, to get a GRIHA rating. In case a GRIHA rating is required for an individual building - coming up within a GRIHA LD rated neighbourhood - then that project can opt to get rated under the GRIHA module for GRIHA LD. The GRIHA module has been designed to rate individual buildings coming up in a GRIHA LD rated campus. The criteria applicable in this case are fewer and the fee is also different. The overlapping criteria have been removed. If the construction of the neighbourhood and the buildings are simultaneous, then the ratings processes will also be simultaneous.
73
Precertification for GRIHA - LD would also be possible?
The GRIHA LD rating has been designed in parts - master plan rating and rating of each individual phase. The master plan rating in GRIHA LD functions as a pre-certification rating.
74
How many stages of energy simulation are required?
Apart from outdoor temperature simulation, shading analysis, day lighting analysis, artificial lighting simulation, whole building energy simulation and thermal comfort analysis Will there be any other requirement for simulation?
Renewable energy simulation is also a part of the GRIHA LD rating. Most of the other simulations have been mentioned by you. There are separate calculators being developed to assist in analysis of each independent section.
75
How many site visits will be made by GRIHA officials and at what stages will there be due diligence report requirements?
There will be a minimum of 1 site visit for the master plan rating and at least 3 site visits for each subsequent stage of construction.
76
Is there any reference manual specifically for GRIHA - LD which defines the stages of certification in a more detailed and elaborate manner?
At present the GRIHA LD has a single manual. Additionally, the Large Area Development guidelines can be used for reference in the same. Please find below the web link for both.
