NORTH BLOCK & SOUTH BLOCK, CENTRAL SECRETARIAT, NEW DELHI

Dynamic Facade Lighting System

Project Name : NORTH BLOCK & SOUTH BLOCK, CENTRAL SECRETARIAT, NEW DELHI

North Block, South Block and Central Secretariat are the living monumental heritage buildings/structures of national/international importance in the Central Vista of New Delhi having attractive architectural features. A large number of VIPs, foreign dignitaries, domestic and foreign tourists visit this area throughout the year. The campus of North Block and South Block being the VIP area and highly secured zone, completing the work within 70 days was very challenging job. Crossing all the hurdles, the work could be completed on target date which was finally formally lighted on 11-10-2017 in the presence of Hon’ble PM.

Dynamic Facade Lighting System
Description

Dynamic façade lighting is capable of providing volume lighting as well as focus lighting having 16 million colour combinations to highlight architectural features of the building. The light fittings have external lenses to facilitate change of beam angles as per site requirement and ease of cleaning.  About 800 light fittings have been used in this project which involves about 40 km long cable laying (Electrical cables & Data cables).  All light fittings have dust, vermin, moisture and outdoor weather protection of the highest order (IP-66) with robust design.   The entire network of dynamic façade lighting system has central computerized programmable control. Complete light system conforms to the most stringent international regulatory and technicalities complying to international standards. 

Luminaries are capable of programming with different audio tracks to produce Light & sound show.

Dimming Capability is also possible in these fittings, this feature is quite useful for lowering the energy consumption as per requirement.

Lights fittings have external lenses to facilitate unique feature to change of beam angle as per location requirement.

Major Gains
  • Night view of Central Vista improved significantly in line with global standard
  • There has been value addition by improving the standard of facade   lighting.
  • There is saving in electrical energy consumption per unit facade area. 

Conventional Lighting

(Being used for 16,750 sq. Mtr.)

Dynamic Façade Lighting

(Being used for 21,450 sq. Mtr.)

(i)    National festival [15 August and 26th January (Total 8 days)]

50000 (No of bulb) x 0.003 (KW per bulb) x 5 (Hour) x 8 (Days) x 8.5 (Unit price) = Rs. 51,000/- per year.

(ii)  Security lighting during year

72 (No of fittings) x 0.2(KW per fitting) x 11 (Hour) x 8.5 (Unit price) x 365 (days) = Rs. 4, 91,436/- per year.

(iii) Conventional Facade lighting

50(KW) x 5 (Hour) x 8.5 (Unit price) x 365 (days) = Rs. 7, 75,625/- per year.

Total Capacity 110 KW (100% load = 1 hour, 50% load 1.5 hours & 25% load = 7.5 hours) = total unit per year 98000KWh

Annual bill =

98000KWh x 8.5 (Unit price)  = Rs. 8,33,000/-

Total annual bill = 51,000 + 7, 75,625 + 4, 91,436 = Rs 13, 18,061/-

Total annual bill = 8,33,000/-

Energy Consumption per sq mtr. of facade = Rs. 78/-

Energy Consumption per sq mtr. of facade = Rs. 39/-

Net saving electricity consumption is to the tune of 50%

 

  • Different lighting themes specific to different occasions have been made  possible
  • There has been significant increase in numbers of tourists visiting Central Vista area.
  • Temporary lighting which was done on these buildings on various occasions was done away with.

Implementation Strategy

Execution Challenge -

1) Both the buildings are of national/international importance in the Central Vista of New Delhi having attractive architectural features, It was prime concern to execute all the work without disturbing original aesthetic look of monuments so most of the execution work was underground work, wherever it was necessary to carry out the work in visible area (Like stone foundations) it was always consulted with concerned officers to improve the look.

2) The work execution of lighting within approx 40 days in a manner such that there should not be any disturbance to the VVIP occupants in the offices including P.M. Office, MHA office, Finance and Defence Ministry offices. So cutting & making good of pathways roads etc was done in night, cable laying and all the cutting/digging work was redone as original before office timing in the morning. So mostly supervision of labour was quite challenging in such security prone area to carry out maximum output.

3) Planning for labour passes  & material passes(as per shorter duration requirement) for night timing was done in best way to avoid unnecessary hindrance at site, key feature for this task was to liaise with various security agencies such as SPG in PMO, H Block for South Block, CISF for North Bloc Delhi Police and traffic police offices for other areas. 

4) Procurement of various materials from abroad (i.e. from Netherland, Mexico, China and other countries) was quite tough job, as during the execution period Mexico was hit by severe earthquake. It was made possible well in time by efforts made at DG, SDG & ADG level along with higher officials of M/s Philips India Lighting Ltd.

Technical Challenge -

1) Execution of Dynamic facade lighting work on such a huge facade area (approx. 21450 sq. m.) with so many aesthetic feature, was quite complicated so arrangements were done for various round of  mock up from different agencies to explore the aesthetic and architectural  features of building.

2) During preparation of NIT it was considered to take concern of technical specification of each item in such a way that all the agencies active in Dynamic Lighting field can participate.

3) As this Dynamic facade lighting work was first of its kind, so maintenance of the fixtures, Control panels and other accessories was a big issue, to counter this issue provision of 5 years of routine preventive & comprehensive maintenance of whole system is included in the NIT.
