CIBSE
CIBSE (Chartered Institution of Building Services Engineers) is the UK's professional body for building services engineering. Its published Guides. Particularly Guide A (Environmental Design), Guide B (HVAC), and Lighting Guide LG7. Are widely referenced in Indian office design, especially on projects for UK-headquartered multinationals or those targeting internationally recognised certifications.
CIBSE LG7, which sets illuminance levels for display screen equipment environments (typically 300–500 lux at the desk with low glare), is commonly used alongside IS 3646 in premium Indian fit-outs. Indian MEP consultants increasingly hold MCIBSE membership, so the guidance is genuinely being applied. Not just cited for proposal purposes.

How CIBSE fits into an office project
CIBSE matters when a workplace moves from a broad design idea to a coordinated brief. The team should define what the term means for this project, where it appears in the drawings or specifications, and who approves it. That prevents a familiar word from hiding a gap in scope, procurement, installation, or handover.
Questions to settle early
- What outcome should CIBSE support for the people using the workplace?
- Which drawings, schedules, samples, or calculations will confirm the requirement?
- What needs to be coordinated with architecture, interiors, MEP, technology, or building management?
What to record in the project brief
Record the selected approach, responsible owner, approval point, relevant exclusions, and the evidence required at installation or handover. If the requirement affects cost, lead time, maintenance, safety, comfort, or future flexibility, state that connection plainly. The definition is a starting point. The project brief turns it into a checkable decision.
A practical checklist for CIBSE
When CIBSE appears in a workplace brief, avoid treating it as a standalone line item. Connect the requirement to the people, spaces, services, and operating routines it is meant to support. A short definition is useful for orientation. A good brief also explains the project context, the expected performance, and the evidence needed before approval.
Before design sign-off
Confirm the existing site condition and any landlord or building-management rules that affect the decision. Mark the requirement on the relevant plans and schedules. Check interfaces with adjacent trades, access for installation, maintenance access, replacement cycles, and the effect on the programme. If alternatives are possible, compare them on whole-life suitability rather than headline purchase price alone.
At procurement and handover
Keep the approved specification, supplier information, samples or calculations, and agreed exclusions together with the project record. At handover, verify that the installed result matches the approved design and that the client receives the information needed to operate and maintain it. This makes CIBSE a useful control in delivery, not just a glossary phrase.
