Clients often ask whether a new office should use IGBC or GRIHA. The first answer is not a preference. It is a scope question. What is being rated, who is the client, what stage is the project at, what evidence can be collected and what outcome has leadership actually approved?
For a Pune or Mumbai project, the useful question is not whether a design looks current. It is whether the brief, building, services, procurement and operating rules agree. The following framework is written for decision-makers who need a workplace that can be priced, built, occupied and maintained.
Begin with the project type
Clarify whether the project is a new building, an existing building, an interior fit-out or a tenant improvement inside someone else's asset. Also record whether the client controls the base building, meters, water systems, envelope and site. A tenant may influence some categories while having no authority over others.
The official IGBC resources and GRIHA rating page should be read directly by the project team. They describe their own systems and should not be collapsed into a casual checklist. The right pathway depends on the project's boundary and the current programme rules.
Separate ambition from certification
A client may want a healthier, lower-energy office without pursuing a formal rating. That is a legitimate brief. Another client may need a registered or certified project for reporting, leasing, investment or brand reasons. Put the intended status in writing so the design team does not assume that a few green products meet it.
Use clear words: design target, registered project, submitted documentation, certified project or internal sustainability brief. Each means something different. This is especially important in marketing copy, where a broad phrase can accidentally overstate a technical outcome.
Map control and evidence
Create a responsibility matrix. Who supplies energy data, water data, material declarations, commissioning records, waste records, drawings and photographs? Which items come from the landlord? Which must be designed, purchased or tested by the tenant? A rating pathway becomes manageable when evidence has an owner and due date.
Do this before procurement. Evidence requested after a product is installed is often harder to obtain, and a substitute may have changed the position. A simple register can track requirement, evidence, source, reviewer and status without pretending the project is already compliant.
Keep the interior honest
Interior choices can improve lighting, controls, material selection, water fixtures, indoor-environment design and user guidance. They cannot by themselves prove performance of the whole building. State the limit of the fit-out scope and identify base-building dependencies.
BEE is the official Indian reference point for energy-efficiency policy and resources. The BEE site is useful for context, while the engineer must confirm the code, calculation method and approval route that apply to the actual building and location.
Design for operations
A rating goal should improve the office after occupation, not only the submission pack. Ask who will operate the controls, maintain filters, manage lighting schedules, monitor water and replace materials. If the facilities team cannot use the system, the design has not delivered its full intent.
Add operator training, manuals and a post-occupancy review to the project plan. The CIBSE Knowledge Portal is a helpful professional knowledge source for building-services questions, but project decisions remain the responsibility of the appointed team.
Report the result precisely
At the end, report what was achieved and what remains outside the scope. A useful case study can say which pathway was selected, what the tenant controlled, what evidence was collected and which operational practices were introduced. It need not turn a partial result into a sweeping certification claim.
That discipline protects the client and improves the next project. Vektor Spaces can connect the sustainability conversation to turnkey office interiors in Pune or Mumbai, provided the scope and evidence are agreed at the start.
Before approval, ask three plain questions. What is known from the site or the client? What is still an assumption? What will prove the decision worked after installation? Put the answers beside the relevant drawing, schedule or source. This keeps the conversation honest when the project moves from strategy to design, from design to procurement and from procurement to handover.
A decision checklist for the project meeting
Use this checklist to turn the article into a controlled next step. It is intentionally practical: each item should have a named owner, a source or drawing, a decision date and a test that another person can verify. If an item is still an assumption, label it as one. That is not a weakness. It is a warning before the assumption reaches procurement or site work.
- Begin with the project type: define the owner, evidence, decision date and acceptance test before the drawing or order is released.
- Separate ambition from certification: define the owner, evidence, decision date and acceptance test before the drawing or order is released.
- Map control and evidence: define the owner, evidence, decision date and acceptance test before the drawing or order is released.
- Keep the interior honest: define the owner, evidence, decision date and acceptance test before the drawing or order is released.
- Design for operations: define the owner, evidence, decision date and acceptance test before the drawing or order is released.
- Report the result precisely: define the owner, evidence, decision date and acceptance test before the drawing or order is released.
For a live project, carry the open questions into the brief, cost plan, programme and handover record. The team should be able to tell what is confirmed, what is provisional, what is excluded and what will be checked after installation. That discipline is more valuable than adding another adjective to the design description.
Decision matrix for this project
This guide is most useful when it becomes a project control. Use the table below to assign an owner, retain the evidence and define what will count as done. It keeps a design conversation connected to procurement, site work and handover.
| Decision area | Question to answer | Evidence to retain |
|---|---|---|
| Project boundary | What part of the building or fit-out is in scope? | Tenant, landlord and base-building responsibility map |
| Ambition | Is the goal better practice, registration, submission or certification? | Written target and approved terminology |
| Evidence | Who owns each document, measurement and test? | Responsibility matrix and evidence register |
| Operations | Will the result be maintained after occupation? | Training, controls and post-occupancy review |
Implementation checklist
Before releasing the next drawing, order or site instruction, check each of these items. A useful checklist does not replace judgement. It makes the judgement visible to the people who must approve, build and operate the workplace.
- Project boundary: record the decision owner, evidence source, decision date and acceptance test.
- Ambition: record the decision owner, evidence source, decision date and acceptance test.
- Evidence: record the decision owner, evidence source, decision date and acceptance test.
- Operations: record the decision owner, evidence source, decision date and acceptance test.
Questions decision-makers ask
The central decision is starting an IGBC or GRIHA conversation by defining project boundary, control, evidence and the intended status. Keep that decision visible in the brief so layout, procurement and delivery choices can be tested against it.
Confirm the evidence listed in the decision matrix: the scope, responsible owner, relevant drawings or records, and the date when the decision will be accepted. Mark assumptions instead of treating them as facts.
Coordinate it before procurement and before ceilings, partitions or services are closed. Late coordination usually turns a design question into a variation, rework or an operational compromise.
Confirm the project boundary and intended status with the client and appointed team before using a rating name in a brief or case study. The useful next step is a controlled review with a named owner, an agreed evidence source and a simple acceptance test.
