Question 1

1. Is EV charging mandatory in new buildings in India?

Accepted Answer

Effectively yes. ECSBC 2024 requires a minimum of 20% of parking capacity to be provided with EV charging facility once a state notifies the code, and the Model Building Bye-Laws amendment of February 2019 places the same 20% of vehicle holding capacity into clause 10.4 for local adoption. What varies between states is adoption and enforcement, not the number.

Question 2

2. How many LEED points can EV charging earn?

Accepted Answer

Up to 2 points under LEED v5 BD+C credit LTc5, Electric Vehicles, in the Location and Transportation category. Installed charging equipment at 5% of commercial bays earns 1 point and 10% earns 2; EV-ready provisioning at 10% of commercial bays earns 1 point on its own. The same bay cannot be counted under both options.

Question 3

3. What is the difference between EV-ready and EV-installed parking?

Accepted Answer

EV-installed means a working charger is mounted and energised. EV-ready means the full circuit exists without the charger: a 208–240 V supply, 40-amp panel capacity, and conduit carrying wiring that terminates in a junction box or charging outlet at the bay, with spare capacity and physical space in the service panel. Both IGBC v4.0 and LEED v5 define it in those terms and award points for it separately.

Question 4

4. Does 20% EV parking mean a 20% bigger electrical connection?

Accepted Answer

No. The codes’ own provision norms assume one slow charger per three four-wheeler EVs, and managed charging sizes the connection to energy delivered across the dwell window rather than to every charger running at once. Forty office bays needing about 20 kWh each over a nine-hour day is roughly 90 kW of average draw against about 300 kW of unmanaged simultaneous peak.

Question 5

5. Which green building certification is strictest on EV charging?

Accepted Answer

Among the voluntary ratings, IGBC Green New Buildings v4.0 asks for the most — 10% of two- and four-wheeler bays for its full 2 points. GRIHA Version 6 asks the least, at 5% of four-wheeler bays for 1 point, and even makes EV optional against two competing strategies. No rating is stricter than India’s mandatory floor: ECSBC’s 20%, 25% or 35% depending on compliance tier.
