The Perforated Façade Punjab Kesari Headquarters

By: Amit Gupta & Britta Knobel Gupta, Studio Symbiosis

The Punjab Kesari Headquarters, currently under construction, recently received the International Property Awards for Best Office Architecture India 2016-17. Sustainability is at the epicentre of the project embedded in form of optimized natural lighting, cross ventilation and reduction of heat gain.

Designed by Studio Symbiosis, the design for the 18,000-square-meter office space is a “Fusion” of traditional Indian architecture and contemporary office space. The main objective is to reduce heat gain and optimize façade opening ratio, ensuring no artificial lighting is required on a typical day. An animated façade is designed as an outcome of different façade opening ratio depending on the orientation. The building is wrapped in a beautiful perforated facade that evokes traditional “Jali” screens and serves to maximize natural light while minimizing heat gain.

Located at an urban corner in Delhi NCR the project looks at integrating with the surroundings with two bold gestures. A sense of invitation with an urban lobby is created whereby the landscape flows inside the building creating seamless movement trajectories extending into the central atrium space. Being an office space, the building is seen as an interaction zone by creating moments allowing informal interaction. A central atrium connects the various floors creating a diffused boundary condition and a visual porosity between people working on different floors. Since the design looks at no artificial lighting, it makes the user feel closer to nature. The office floors are dividable into smaller units to achieve flexible units ranging from 500 to 2000sqm.

The Façade Design

The inspiration was to translate a traditional Indian façade pattern by using digital simulations into an iterative process to create a responsive built form. This traditional “Jali” screen creates culturally a cultural sense of belonging. Lux level of 500 has been achieved in the building at a workstation height from each floor plate, along with a daylight factor of 2 over 80per cent of the floor plate; this is done to ensure that artificial lighting is not required inside the building on a normal day.

A hexagonal pattern was used as a base and through iterative process various porosity patterns were generated from it to create different light conditions. This resulted in a variable opacity condition in the façade that had a dual purpose of creating performative architecture and also created variable openings on the façade in various orientations generating a design for the façade that is animating and has an inherent meaning.

This resulting pattern morphs from 81 per cent opacity on the north façade to 27 per cent opacity on the south façade, with an intermediate opacity of 54 per cent on East and 62 per cent on west façade respectively. The Jali façade is made of Glass Reinforced Concrete panels.

In terms of construction tolerances a system has been adopted whereby through computer numerical control (CNC), milling, a mould will be created for the façade pattern and this mould will be used for casting the façade panels. The curvature of the entrance will be also casted using this process whereby by using digital fabrication of mould a higher accuracy in the design is achieved.

The double jali screen reduces the outside air temperature in front of the glass. The colder air is going in and pulled into the atrium through the chimney effect of the atrium space and resulting in natural ventilation and reducing the indoor air temperature naturally so the cooling load for the air conditioning is reduced. The project design was commissioned in 2014 and went into construction in August 2015. The opening date for the project is January 2017.
