Ideas Beyond Green Sustainable Design Part
There are many supporting teams of experts within Samoo Architects & Engineers (Samoo) that provide assistance to the design function of the organization. We would like to introduce one of these teams of experts: Sustainable Design Part within ENG Team, which is in charge of eco-friendly and sustainable design. What do we do at Sustainable Design Part? Among many technical support parts under ENG Team, Sustainable Design Part is specialized in providing environment-friendly design support. Based on sustainability-related know how and technology, the Part is participating in around 50 design projects every year, providing professional consulting. Its areas of expertise include: i) eco-friendly design strategy development based on climate analysis, ii) environment-related simulation such as building energy simulation (ES) based on sunlight and solar radiation, and CFD (Computational Fluid Dynamics), as well as iii) consulting on global certification and Korean sustainable building-related laws & regulations. More recently, consulting demands on light reflection, condensation, or stack effect are increasing backed by the growing interest of clients in sustainability. What makes Sustainable Design Part special?Green Tomorrow, a project which Samoo participated not only in the consulting and design stages, but also in the construction process, is the first-ever zero-energy building in Korea and the first building that has achieved the LEED (Leadership in Energy and Environmental Design) Platinum rating in the nation. This masterpiece, built 10 years ago, was in itself a concentrate of all the environment-friendly technologies there were back then, and it holds significance in that it has made the Sustainable Design Part what it is today. Had the Sustainable Design Part simply stayed as a supporting function to the design division, it would not have become the technical expert it is today. Sustainable Design Part is a supporting function, but, in many cases, it actually designed the lay out of sustainability-focused projects and provided environment-related consulting directly and solely to the clients. These experiences played a crucial role in accumulating the know how and professional technologies.When it comes to building an environment-friendly building, understanding the unique demand of the project and choosing the right technology, be it simple or high-tech, is important. That is, the work has to go beyond the simple combination of general technologies out there. At Sustainable Design Part, professional architects specialized in the environment-friendly field and engineers of LEED AP, CFD, or building energy work hand-in-hand and in close cooperation to present the clients with an optimal-possible environment-friendly architecture. Environmentally-sustainable building is not valued by the technical items applied, but by the energy performance realized by those technologies. What really matters, in fact, is whether the level of illuminance is achieved with daylight as planned, whether the energy conservation is successfully achieved, or whether the natural ventilation is working. To ensure such performance, Sustainable Design Part runs simulations on building environment, CFD, and building energy with its own capacity, thereby providing data-based and trustworthy sustainable buidling design. As a result, the Part has been releasing a series of publications namely, LEED Guidebook (2010), ECOTECT Handbook (2012), Eco Factory Global Design Guideline (2015), CFD Project Casebook (2017), and Envelope Design Guide (2018). What is our core strength?Sunlight analysis, for optimal building environmentSunlight is crucial in creating healthy indoor environment and securing a good amount of daylight. These days, more people are aware of the importance of sunlight, and its analysis results are often debated in courts with the introduction of Educational and Environmental Impact Assessment System in Korea. To cope with such trend and improve the credibility of its sunlight environment analysis result, Sustainable Design Part has adopted analysis tools specialized in daylight analysis such as ECOTECT or Sanalyst. CFD (Computational Fluid Dynamics) Analysis, a topic of growing attentionThough invisible, fluid constantly flows within an architecture, and CFD simulation helps predict the flow of such invisible fluid. Based on the simulation result, Sustainable Design Part provides consulting on wind environment, thermal comfort, optimization of HVAC system, double-skin facade, pollutants dispersion, etc. With the growing number of high-rise residential buildings, more people are suffering from issues of stack effect, such as elevator disfunctioning and inability to open elevator doors due to a pressure difference, or spread of smell from a restaurant to the entire building. Sustainable Design Part of Samoo developed the “Design Guideline for Reduction of Stack Effect”, based on which it delivers a differentiated consulting.Insulation/Condensation Consulting to Ensure Basic Building PerformanceSimply developing and using thicker insulator is no longer enough to prevent energy loss and meet the thermal insulation standards of Korea. Just like a swimming tube loses all its air through a tiny hole, a thermal bridge can cause significant heat loss and dew condensation. Sustainable Design Part performs insulation/condensation consulting based on its examination on high condensation risk areas and heat transfer simulation results.Daylight Reflection on Building Facade, One of the Recent Issues in Building EnvironmentAlong with the trend of larger buildings with bigger windows inevitably comes the issue of daylight reflection. Though it is tricky to quantify the correct amount of damage from daylight reflection as it changes every minute and second, Sustainable Design Part is providing related consulting based on ECOTECT Analysis, a construction environment analysis program.What we do to prepare for the next stage?Climate Analysis Platform based on Business Intelligence (BI)Sustainable Design Part has recently developed the “Global Climate Analysis Platform” based on BI technology. This remarkable plateform generates not only the local climate data but also various unique visualization automatically. Furthermore, it provides the user with an appropriate eco-friendly design guide for a chosen location.Introduction of Environmental Analysis based on Graphical Algorithm Editor Integraded Design Tools and BIM (Building Information Modeling)Many analysis tools have been developed for environmental analysis of buildings, but some does not support the function the user needs, while others may not be suitable for effective parametric analysis. Against such backdrop, Sustainable Design Part is building an analysis script based on grapical algorithm editor-intergrated design tools such as Grasshopper or Dynamo. Sustainable Design Part plans to bring its environmental consulting to a more sophisticated level by applying such new tools to a wider range of analytic areas such as sunlight/solar radiation, building energy, and daylight relfection.
