The building and 200 acres of surrounding grounds were designed by noted architect Louis Kahn. At first glance the bare concrete walls and giant geometric shapes,
along with the massive staircases leading to the main building, can cause it to appear quite imposing, but extended viewings reveal the beauty and impressiveness of the
design.
The central part of the building is 47 metres tall and contains the main Parliament Chamber, while the surrounding 8 wings are 33 metres tall and include offices,
meeting rooms, store rooms and all the other necessities of officialdom.

Climatic performanceThe architect orientated the building and positioned the openings after studying the climate,sun-path and direction of summer breezes. All the apertures and gardens have been positionedwith consideration for the 24.5-latitude tilt of the sun-path in Dhaka. The sunshades over thewindows cut out direct sunlight during the summer but allow the summer breeze (from thesouth-east) to filter through. During the winter months, as the sun inclines further south,sunlight enters the rooms and lends warmth. Cold winds are avoided as the wind blows fromthe north in the winter. The gardens also give a soothing effect.In contrast to all the other new construction in the old city, this building provides good
ventilation, ample natural light and some attractive views. A special window with fixed glassand adjustable louvres called the fuchkee khirki has been provided in each apartment. Thisserves as a viewing corner to observe the life in the street without being noticed by peopleoutside.C. Response to treatment of water and rainfallDhaka has rain for a good two-thirds of the year, although 80 per cent of the annual averagerainfall of 1,854 millimetres falls between May and September. The gradual slope on the roofensures that water does not accumulate. In addition, two coats of locally produced Desalt-SO1

and Hydroseal EF-34 have been applied on vertical brick surfaces to avoid possible waterabsorption, salinity and growth of algae.All gardens, verandas / balconies and the roof of these spaces have been treated with dampproofcourses. The drainpipes allow water to pass through and prevent it from collecting andcausing seepage.
Environmental responseThe view from any rooftop in the old city comprises a conglomeration of buildings varying in
height from two storeys (fast disappearing) to seven storeys, with the odd old tree growingout of this concrete jungle. These now-mature trees were planted in the courtyards oftraditional houses, and are disappearing as new larger and higher buildings replace thecourtyard houses. In some cases the new buildings include a small light well and save a treeor two in the process. The Kazedewan building has reinterpreted the central courtyard trees byproviding gardens at various levels using indigenous plant material.E. Choice of materials and level of technologyThe determining factors in the choice of structure, materials and construction technology wereprevailing practice, climate, economy and maintenance. Technology has been kept simple, ata level that local workers and craftsmen could handle. The RCC members exposed on theexterior of the building have been finished with SARA to resist the impact of the extreme wetweather and the dry winds in winter.9
Climatic conditionsDhaka is located in the geographic centre of the country, in the great deltaic region of theGanges and Brahmaputra rivers. It is served by the port of Narayanganj, located sixteenkilometres to the south-east. The city is within the monsoon climate zone, with an averageannual temperature of 25C and monthly mean temperatures varying between 18C in Januaryand 29C in August. Nearly 80 per cent of the average annual rainfall of 1,854 millimetres (73inches) occurs between May and September.
