Occupancy Density
Occupancy density is the number of people per unit area of floor space, typically expressed as square metres per person. It is a primary input for space planning, HVAC sizing, egress calculations, and overall fit-out cost per seat.
Indian office design benchmarks typically target 8–12 sq m per workstation for open-plan Activity-Based Working environments; 12–16 sq m per person for more traditional assigned-desk layouts with meeting rooms and support spaces included. Higher occupancy density. Below 8 sq m per person. Creates thermal and acoustic problems that are expensive to fix after fit-out. HVAC systems must be designed for peak occupancy plus equipment loads; underspecifying for actual headcount leads to persistent overheating complaints. Always calculate density against carpet area, not super BUA.

How Occupancy Density fits into an office project
Occupancy Density 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 Occupancy Density 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 Occupancy Density
When Occupancy Density 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 Occupancy Density a useful control in delivery, not just a glossary phrase.
