Rather than the traditional approach of learning at sustainable design purely from an energy and environmental perspective, GreenDwell also considers and concerns the human aspect of sustainability.
The company believes that how people experience space through time defines their well-being.
The company uses a Green Research-Integrated Design (g.r.i.d) process to hypothesize the varied senses that residents and community might experience once the building is fully completed.
Computer simulation tools are used because the ‘sensual experience tester’ to exceedingly assist architects check for the sensual performance early within the design phase.
Most importantly, visual, thermal, and acoustic comfort, alongside the building’s environmental impacts were analysed in this design.
In consequence, the corporates creates an experience that's a gratification to the senses, while minimizing negative effects on the surrounding environment.
Given that the team services primarily to clients in Thailand, which in most time of the year is a hot and humid country, shade and natural ventilation play a strongly important role in design.
Also, for projects set in urban areas, the planning must to weigh up existing obstructions and their impact on wind profile on the location. The foremost efficient course of action to accomplish this is by assimilating ventilation simulation throughout the planning process.
At the advanced design stages, the team required the ability to check for parameters like the opening dimension and distance between each building mass to assist design decisions.
Conventional CFD tools fell short for their purpose. Therefore, even testing of basic design questions takes an excessive amount of time.
Since the workflow from the modelling tool into simulation was fairly simple, it proved to be exceptionally user-friendly. The standard of the output was so great visually, that it could directly be included in client presentations.
One of the projects where scSTREAM proved to be extremely useful was for a kindergarten project located in an urban site. The location had several neighbouring buildings that were obstructing ventilation.
Also, there have been existing large shade-giving trees on the location. one among the design objectives was to make sure that the childs be ready to frolic around and play within the tree shade without having to depend on air conditioning.
The simulation helped the team confirm that the breeze was following an unusual pattern, entering and exiting from the narrow side from back to front. This was a diametrically different from the predicted wind profile. The simulation results helped the planning team to conceptualize the building form and optimize the ‘wind channel’. The building shape was designed accordingly to reinforce the wind profile into the pocket courts, which were to be used for the children’s play area.
Since it is cool and windy, the children truly enjoy and appreciate utilizing the space. Even on days when wind is scarce, ceiling fans are sufficient to ensure comfort.
GreenDwell team was ready to overcome a number of the challenges that the location posed, through an incorporated work process aided by scSTREAM. The presence of a reliable ventilation simulation tool played an enormous role in empowering effective design decisions.
