1,000 officials. The building also features a 500-seat auditorium, a 100-seat conference hall and 70 toilets with facilities for disabled people. The building has been able to reduce energy consumption by 20 percent by means of a water-cooled air-conditioning system and heat-reflective tiles on the roof. The building has been designed in a post-modern style, with some elements of traditional architecture. Some design elements would suit the colonial-style architecture of the Ripon Buildings. Restoration In 2012, a massive renovation was initiated at a cost of 77 million under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM), to preserve the building's original grandeur. Under this, an annexe building measuring 12,540 sq m will be constructed alongside the main structure to house all the departments of the corporation, and all structures in the premises that do not blend in with the main structure aesthetically will be demolished in June 2013 when the annexe building is completed. The annexe building, with an auditorium to seat 500 persons, will be built in a contemporary and post-modern style, highlighting with elements of regional architecture, to blend with the Indo-Saracenic style of the main building. The main building is also being renovated under the process with the use of lime mortar for plastering. It is the first heritage building in the country to have received funds from JNNURM for renovation.
