Sustainability and sustainability design studio ZED Lab has completed a perforated concrete hostel in Guruguram
January 21, 2021
Design studio Zero Energy Design Lab has built a hostel in the Indian city of Guruguram for students of the Institute of Technology and Management of St. Andrews. In a building made of red perforated concrete blocks with a total area of 2322 sq. m can accommodate up to 130 people.
The main challenge for the designers was to create an ergonomic space with zero energy consumption that would suit the local climatic conditions. Since the air temperature in Guruguram can reach almost 40 ° C, it was important to consider a natural ventilation system. To do this, the team used parametric design techniques and conducted a thorough analysis of solar radiation.
The two-layer facade provides thermal insulation and light transmission at any time of the day, thanks to which shady areas and natural ventilation are always preserved inside the building. The first “layer” is a brick wall, which blocks the directional rays of the sun, the second & nbsp; – an intermediate space where the stairs and terraces are located. “We thought a two-layer façade would be the perfect solution to thermal comfort in response to the region’s hot and dry climate,” & nbsp; explains ZED Lab founder Sachin Rastogi.
The angles of rotation of each block were calculated using special software tools. As a result, the designers were able to reduce the exposure to direct sunlight by 35%. “Since the blocks have a through hole, the volume of air passing through them loses heat due to compression in accordance with the Bernoulli principle,” Rastogi explained.
Inside, the hostel is designed as a social center with numerous private areas. The heart of the building & nbsp; is a staircase that adorns the southern facade of the building and connects all floors. The stairwells function throughout the day as a public space where students can study, work or play. The outer lobby is often used as a badminton court in the evenings, while the inner courtyard has chess and carom playgrounds.

Despite the industrial appearance of the building, the design of the hostel refers to traditional Indian architecture, which is characterized by a similar approach to construction, taking into account climatic conditions and minimizing energy use. The so-called aangana, or courtyards, have always been a hallmark of Indian architecture, & nbsp; – they facilitate air circulation and fill the interior with light.
