Reaching Design Solutions Using Building Technology Simulation: New Thai Parliament Design Competition

Main Article Content

Under the current environmental and energy concerns, architects are forced to design better buildings which are both energy efficient and environmental friendly. Green ideas
and concepts presented by designers are typically sketches and simple design diagrams which come from past design experiences and expertise. Design solutions derived by such
process are skeptical because it lacks the measurable outcomes. To solve this problem, one of the solutions is to utilize computer which increasingly plays significant roles in building
simulations. Many progresses were made for better users’ interfaces, accuracy, and computation speed. This article will demonstrate the emerging simulation technology that could
aid the design decision making process based on simulated data including air temperature, solar radiation, wind speed, daylighting level, and others. One of the five finalists in Thai
parliament design competition is the case study for demonstrating this design with computer simulation process. Using well recognized and state-of-the-art software including
ANSYS CFX and eCOTECT, major components of this parliament were selected and simulated under specific design inquiries involving atrium design, shading device, and skylight
design. In this study, CFD (Computational Fluid Dynamics) data from ANSYS CFX helps designers select proper atrium ventilation and fenestration systems. At the same time,
radiation and daylighting data can optimize shading device, façade, and skylight design. Enhanced by this process and measurable outcomes, the designers can be confident in their final design solution which could improve both energy and environmental performances. For any future projects, this article is an example of how building technology simulation and architectural design could play hand-in-hand and, in turn, came up with the better design solutions as well as effective design process.
