Arts Tower Forecourt -conceptual proposal and analysis
[2018]
Location : Sheffield, United Kingdom
Arts Tower, one of the most iconic buildings of Sheffield University campus was proposed with a masterplan for its forecourt. The project was to evaluate and analyse the effect of the proposal on the urban neighbourhood for the present and the future climatic conditions. The proposal was to remove the vehicles in the forecourt to accommodate a cafeteria and a plaza. The design decisions are made with the help of simulation and analysis for the site and the building itself.

Creative Arts Center - sustainable refurbishment [2019] Location : Hong Kong, China
The retrofitting of Jockey Club for Creative Arts Centre [JCCAC] is done by considering the key aspects of integrating sustainable strategies to enhance the building performance and the occupants’ experience with the built environment. Hong Kong being one of the fastest growing city demands the architecture to adapt to its rapid changes in terms of environment, climate and user needs. The new design change for the building is proposed for improving the building performance by the detailed analysis of site and climate context along with the consideration of user requirements in the building. The problems in these areas are identified and the necessary solutions are proposed by integrating innovative sustainable design ideas.
KEY SUSTAINABLE STRATEGIES IMPROVING URBAN CONNECTION AND SOCIAL INTERACTION

RE- ZONING THE SPACES JCCAC as an arts center gathers artists from different disciplines like fine arts, pottery, fashion designing etc., But it not only works as a centre for artists but also for the community. Hence the spaces are re-zoned to make the building function as a place where art and community gathers. The spaces create an unique atmosphere which offers social interaction between tenants and visitors, artists and students. As a result, different spaces are created that improve social interaction and enhance the connection between the surrounding context and the nature.

IMPROVING DAYLIGHTING AND NATURAL VENTILATION Many strategies are adapted in the building exterior and interior spaces yo improve daylighting and natural ventilation. The internal spaces and the openings in the facade are altered to improve the quality of natural lighting and to promote passive ventilation.
STACK EFFECT Promotes passive cooling
The south-east facade being the most effected by the excessive solar heat, the balconies are introduced at different levels with different depths. As a result the facade will be shaded in the summer cutting harsh sun and in winter it allows the natural lighting inside the building.
GREEN ROOF Reducing the impact of urban flooding and providing insulation against summer sun

Green BIM- Parametric kinetic shading panel [2019] Location : Hong Kong, China
Green BIM is creating a new paradigm in the field of sustainable architecture. The application of BIM in the integration of sustainable design and analysis is the main aspect of this project. The same sustainable retrofitting project is considered for the experimentation of kinetic shading panel with the help of Dynamo and Revit. Hong Kong being located in the hot climate, south eastern faรงade is more often exposed to direct sun. Hence the idea of double skin faรงade is conceived and the kinetic shading panels are designed for this exterior skin. The opening of these shading panels is controlled by the amount of solar radiation received by each panel and thus preventing the building from excessive solar heat gain.
DESIGN METHODOLOGY • Design- Designing a solar shading device to enhance the performance of the building energy with the help of Revit curtain panel pattern based family. N_HT

CONCEPT AND DESIGN OF KINETIC SHADING PANEL The kinetic shading panel is created in a ‘curtain panel pattern based’ family using a square grid. The square grid is divided into four equal isosceles triangles which forms the movable parts of the panel. The outer square panel supports the triangular panels forming a structure and also act as a brise-soleil system providing shade to the facade. N_HT=1 [when solar radiation is highest]

Institute of Journalism -urban intervention [2017] Location : Bangalore,India
As truth and honesty are the guiding principles for journalism, so are they to the design of the building. The composition is kinetic and dynamic - symbols of journalism and media’s role our society. The site being located in the heart of Bangalore city - M.G. Road is a hub of recreational and commercial activity in the city. Swarming with varsatile and diverse age of people at almost all the times of the day, provides a wonderful oppurtunity for the college of Journalism to use the city as a classroom and a living lab for learning.
DESIGN CONCEPT The site has M.G. road to the north and Church street to the south which are the most happening streets in the city.The concept was to create a connection between these two roads to have interactive public spaces in the ground floor such as collaborative workshop spaces, cafe, auditorium and a large landscaped area in the middle. The open and the built form interacts with each other. The central landscaped area supports the formal and informal engagement of students with public. The site is surrounded by huge looking buildings which are mainly commercial and office blocks. There is a great need of open public space where people can sit and relax.

SPATIAL ORGANISATION The main concept of zoning is conceived by the idea of reinterpretation of courtyard system. This system of zoning which was adopted in many traditional buildings of India has an effective circulation system and also greatly affects the micro climate of the building. The whole building is maintained as low rise to maintain quarry as a backdrop. Outreach spaces such as classrooms, workshops and library spaces are near to the settlement area which needs an ease of public access. The research spaces are placed at the rear end of the building and captures magnificient views of the quarry. Sustainable farming techniques and rain water harvesting techniques are adopted in the site. Along with this, suitable methods are adopted for the rejuvenation of quarry lakes which is the main source of water for quarry people.
