Architecture has in the past done great things for geometry. Together with the need to measure the land they lived on, it was people’s need to build their buildings that caused them to first investigate the theory of form and shape. A building does not only needs to be structurally sound and aesthetically pleasing, it also has to comply with planning regulations, bow to budget constraints, optimally fit its purpose and maximise energy efficiency. To this extent, the Diamond shape represents an optimal design approach to achieve energy efficiency. And in some cases it also symbolizes transparency, value and durability.
Seoul Energy Dream Center
The first example of this “breathing diamond” is Seoul Energy Dream Center, designed by Fraunhofer Institute for Solar Energy System ISE, Germany. The building and its diamond-shaped architecture aims to teach citizen the importance of energy savings, sustainable architecture and center for renewable energy.
The three story building structure extends upwards and outwards at a 45 degree rotation,topped off by a square roof. Wedge-shaped roof projections are mounted along the façades at an upward tilt – giving the effect of wings. These protrusions shield the entrance area from the elements as well as provide fixed solar protection for the window glazing. Strict geometrical angles also characterize the façades. Because the underground at the site is not capable of bearing weight, the building is supported by piles which are mounted on a reinforced concrete base plate. The angular projection roofs also have a functional role in stabilizing the building.
Seoul Energy Dream Center demonstrates the of the latest technologies, successful use of renewable energies and holistic approach used for its building concept to determine the thermal and daylight building performance. The entire concept covering the energy and the technical aspects is customized for the comfort of the building occupants as well as for the climatic and technical boundary conditions in South Korea. One of the unique features of the building is the positioning of the angles to generate an external façade.
The angle was carefully calculated. The building can be protected from excessive sunlight in summer and benefit from it in winter. All the windows also have automatic exterior blinds designed to regulate the amount of light coming into the building. The windows are in three layers ,fitted to retain the building’s heat. Hot water comes from the underground heat storage, which is used to provide the building’s basic heating. By applying these collective measures, the heating and cooling energy consumption of this building is 70 percent less than the standard consumption for South Korean buildings.
The Bangkok University
The Bangkok University Landmark Complex designed by Architects 49, built on with the concepts of reorganizing the campus frontal area and creating impressive landmark approach to the university. It designed with contemporary forms and the symbol of the university, a diamond. The pond is placed in the front of the building so it creates a reflecting effect of the building forms. Moreover, it also serves as a natural barrier as well as the campus’s reservoir. Bangkok University has a good indoor air quality sunlight access to provides a pleasant studying environment.
The diamond building represents a new approach toward climate responsive building design in Thailand. The design considers visual and functional continuity between the front area and the rear of the campus so the entire campus is inextricably intertwined. The Bangkok University Diamond integrates Green Architect in its design and is equipped with the Building Automation Systems (BAS) controls all of the utilities in the buildings, including the sustainable and environmentally-friendly recycling program.
Building Automation Systems (BAS) are centralized, interlinked, networks of hardware and software which monitor and control the environment in commercial, industrial and institutional facilities. While managing various building systems, the automation system ensures the operational performance of the facility as well as the comfort and safety of building occupants. Generally, BAS with control of mechanical, electrical and plumbing (MEP) systems. For instance, the heating, ventilation and air conditioning (HVAC) system is almost controlled, including control of its various pieces of equipment such as : chillers, boilers, air handling units (AHU)s, roof top units (RTU)s, fan coil units (FCU)s, heat pump units (HPU)s and variable air volume boxes (VAV)s.
