Undergraduate Studio Projects

Methodology:Students will work individually on a 8 x 24base with planes(square/triangular/rectangularshape) of varying size and monochromatic colour. Number of planes may vary from a minimum of 20 tomaximum unlimited. Planes may intersect but cannotbe perforated.

Media: Red Paper, Grey Paper

Duration:One week.

A line extended becomes a plane conceptually a plane has length and width but no depth. In the formation of visual construction, a plane serves to define the limits or boundaries of a volume. As architecture deals specially with the formation of three-dimensional volumes of form and space, the plane becomes a key element in the vocabulary of architectural design.

Won the BERGER BEST DESIGN AWARD 2008-09 for the design of a 'Preschool and child care center'

Children are the pioneer of the future. Every children possess its own creativity, exploring capability and dream. A pre school and child care center is a place where they start to learn about the surrounding world and develop communication skills.

The pre school and child care center has to be a second home for the children. Its environment should be inviting to learn, explore and play.

In this project the pre school and child care center was designed with the view to focus the softness and play full character of the children. The main part of the site is the play ground, which is the most interesting part of the site for the children. They will explore the building as a toy. Its fluid character of the interior and exterior spaces will reveal the building to the children as if they are living and playing in a toy.

design of a Ready Made Garments Factory

In previous studies it was found that an efficient lighting and ventilation system can reinforce the production of a ready made garments factory. Bangladesh has a tropical climate. This climatic condition enables the use of daylight through out day time and the utilization of wind and rainwater in natural ventilation and rain water harvesting respectively.

The main motivation of this design was to give the workers a work place with sufficient natural settings. The provision of sufficient glare free daylight and fresh natural air for every worker was a major goal of this design. Also water efficiency of the project was another important issue. The functional efficiency was equally important for the project. As it is a factory building the work flow and the zoning has to be flawless and efficient.

The area of the site is 2385 sqm. The main zones of the building are the production & distribution area, Administrative area, Training and testing area and the Service area. The main part of the building is the sewing area, which is in the middle with administrative area, training and testing areas to the left and distribution & service areas to the right.

From cutting to the packaging all the steps can be performed in well light and naturally ventilated spaces. The solar power generated from the roof will light the interior at night. The construction system is tensile and frame structure. This will enable the fast construction process within 2-3weeks. The material used in the roof and exterior surface is Corrugated Galvanized Iron (CGI) sheets, which is well-found in Bangladesh. But it has some designed modifications to reduce the thermal heat gain.

The width of the sewing area is 150' in the North-South direction. It is possible to ensure cross ventilation as the main source of wind in Bangladesh is the south side. But the main problem is the sewing lines. There are six lines. The first line in the south side will get fresh air. But as the air will travel in the inner part of the sewing section the next lines will get hotter air with less oxygen components for the metabolism of the workers. That's why in the design there was a duct beneath the floor to supply fresh air to the middle portion of the sewing area. The mixed air then travels through out the system creating a well ventilated space. The position of the exhaust fans and the inlets & outlets were simulated with Comsol Multi-Physics 3.4.

Use of natural and artificial Ventilation

Natural ventilation

Artificial ventilation

The use of electricity in per square feet is rising with the increasing in the use of artificial lighting and artificial ventilation. So, these types of multistoried shopping environments are increasing the use of energy at a higher rate.

In this study parametric study was done to identify and quantify the effect of each individual factor/parameters on daylight and natural ventilation. The main focus was to develop relations between the parameters of the shopping environments to maximize the use of daylight and natural ventilation. The parameters which were considered in this study were- width, height and depth of the shops; the depth of the corridor between two rows of shops; the height and width of the light wells. All the parametric relations are derived in the form of proportion to the width of the shop. As a part of idea testing, the findings of parametric study were applied through designing a retail shopping mall. Daylight and natural ventilation level were measured and compared with the given level in the BNBC code.
