Draw the line first
Discussions of green offices often begin with solar panels, rainwater harvesting and high-performance façades. These matter, but in a leased office in an Indian tech park or business district they usually belong to the building owner. A tenant taking a floor on a three or five year lease rarely controls the glass, the roof or the central plant.
What the tenant does control is significant. The interior fit-out decides how much new material is brought in, what chemicals are released into the air, how much energy the lighting and local cooling use, how water is used in pantries and toilets, and how much waste leaves the site. A clear view of what is within reach keeps effort focused where it can make a difference.
Make a simple list at the start of the project, in two columns. In one, write what belongs to the building: façade, central chillers, base build services, common areas. In the other, write what belongs to you: partitions, ceilings, finishes, furniture, lighting, local AC, fixtures and the way the office is run. Then ask the landlord what the building already provides and what data, such as energy metering, they can share.
Reuse before new
The most sustainable material is the one that is already there. Many offices are handed over with ceilings, flooring, partitions or toilets from a previous tenant. Before removing them, check their condition. A sound grid may need new tiles rather than a new structure. Existing carpet tiles may clean up well. Glass partitions can sometimes be relocated rather than demolished.
The same applies to furniture. Workstations, storage and chairs from an older office can often be refurbished, reupholstered or reconfigured. Where new items are needed, ask suppliers whether they offer take-back or refurbishment programmes.
When demolition is unavoidable, segregate materials on site so that metal, glass, gypsum and timber can go to recyclers rather than to a landfill.
Choose materials for what they release and how long they last
Paints, adhesives, sealants, laminates and composite boards can release volatile organic compounds, or VOCs, into the air for weeks or months after installation. These affect air quality and can cause headaches or irritation, especially in sealed, air-conditioned offices. Low-VOC paints and adhesives are widely available in India; ask for the product data sheets and the stated VOC content, and allow the space to air out before people move in.
For timber, ask for wood from certified, responsibly managed sources, or for engineered boards with low formaldehyde emissions. Consider local materials such as Kota stone, terracotta or bamboo, which often have shorter supply chains and suit the climate.
Durability is part of sustainability. A cheap finish that fails in two years and must be replaced uses more resources than a robust one that lasts the lease. In Indian conditions, consider how materials respond to dust, humidity and heavy cleaning.
Light and cool only what is used
Lighting and air conditioning are usually the largest energy loads within a tenant's control.
- Use LED fittings throughout, with efficient drivers and good optics, so that fewer fittings achieve the required level.
- Add occupancy sensors in meeting rooms, cabins, toilets and stores, and daylight sensors along the façade.
- Zone the lighting so that sections of the floor can be switched off when unoccupied.
- Zone the AC so that meeting rooms, server rooms and open areas can be controlled independently. Where VRV or split systems are used, choose efficient units and place them to avoid cooling empty areas.
- Separate always-on loads, such as server rooms, from general loads so that the rest can be switched off overnight.
The Bureau of Energy Efficiency publishes the Energy Conservation Building Code and star ratings for equipment, which are useful references when comparing options.
Water and waste
In pantries and toilets, low-flow taps, aerators, dual-flush cisterns and sensor taps reduce water use without changing how people work. Check that fixtures are compatible with the building's water pressure. Where a pantry has a dishwasher or coffee machine, choose efficient models and plan for proper drainage.
A fit-out site generates offcuts, packaging and debris. Ask the contractor to segregate waste on site, to return pallets and packaging to suppliers where possible, and to record what is recycled. Order materials carefully to reduce surplus.
Once the office is running, plan the pantry and print areas with space for segregated bins: wet waste, dry recyclables and electronic waste. Without that space, segregation rarely happens.
Use a framework as a checklist
Rating systems help structure decisions, even if certification is not the goal. The IGBC Green Interiors rating system, from the Indian Green Building Council, is written specifically for interior fit-outs and covers materials, indoor environmental quality, energy, water and waste. GRIHA, India's national rating system, offers another reference. Reading through either one before design begins turns good intentions into a practical list.
Make it part of the brief
Sustainability works best when it is written into the brief alongside area, budget and timeline. Decide what matters most to your organisation: air quality, energy, material reuse or waste. Set measurable goals where possible, and ask your design team how each will be addressed. A short list of clear priorities agreed at the start does more than a long list added at the end.
