      6 COMMERCIAL DEVELOPMENTS

      This is a pioneering project that pushes forward many of the concepts and ecophilic technologies

      that Yeang has recently been developing. Two tower blocks house a unique 14-storey mixed-

      commercial development in the city of Putrajaya (Malaysia) that blends cultural heritage with

      cutting-edge ecological advancements. Its creation is intended as a series of public realms

      surrounding an iconic built form.

      The faceted diamond-shaped facade of the building is sculpted to present itself as a crystalline

      structure, rather like a gemstone. It cleverly anchors itself to the local culture by covering

      itself in two 'skins' with an air-gap in between. The first skin is clear glass, and the second is

      fritted using the 'Songket' pattern (a time-honoured handwoven Malay fabric). It concurrently

      provides decoration and also 50% opacity, creating sunshading for the interior spaces.

      The double-skin facade on the west of the building is placed to reduce the overall thermal

      transmission value (OTTV) from the afternoon sun, and is perforated with vegetated terraces

      and balconies spilling an abundance of greenery into the communal areas, enhancing local

      biodiversity and living quality.

      The axis points the direction from

      Millennium Monument to the boulevard

      leading to the Prime Minister's Office.

      SUASANA PUTRAJAYA 7

      A linked planting system naturally filters and drains surface run-off water into a centralised gravity-

      fed irrigation system, which in turn maintains an impressive green linear habitat filled with various

      planting species that sits as the centre-piece of the 7-storey entrance atrium. Flora and fauna

      are selected carefully in order to design a desirable habitat for this particular location, by first

      looking at which species of fauna are preferred for conservation and biodiversity reasons, and

      then selecting the correct flora that will be both native and attract the right fauna. Of its many

      eco-friendly assets, a particular innovation is the application of an 'Eco-cell' that contributes to the

      holistic cycle of the building. This is a shaft in built form, bringing light, harvested rainwater, natural

      ventilation, and vegetation right down into the lowest basement levels.

      The partially symmetrical towers sandwich a landscaped promenade on the ground level,

      that opens up to an active public realm, encouraging a similar sense of community with

      seating pavilions, planting areas, relaxation zones, reflective pools, and temporal event

      spaces. Verandas give way to covered and/or shaded walkways within the ground floor of the

      building, reminiscent of the 'Kaki Lima' (the five-foot walkway) in front of the traditional pre-

      war shop-houses of Malaysia's old towns. In a wider context, the concourse and two towers

      arrangement is specifically aligned so that a visual axis is maintained, running from the

      Millennium Monument through to the Prime Minister's Office.
