GreenDwell provides design and consultancy services for Residential and Commercial buildings supported the principles of sustainable design.

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 communities might experience once the building is fully completed.

Computer simulation tools are used because the ‘sensual experience tester’ to exceedingly assist architects to check for the sensual performance early within the design phase.

Most importantly, visual, thermal, and acoustic comfort, alongside the building’s environmental impacts were analyzed in this design.

In consequence, the corporates create 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 the design.

Also, for projects set in urban areas, the planning must 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.

MSC Solution

Greendwell at first attempted to figure with basic software tools, yet these were appropriate to be utilized distinctly at the conceptual plan stages since they weren't prepared to deal with parts of simulation like grid size and grid limitation.

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.

The company then decided to use scSTREAM, a general-purpose thermo-fluid analysis system with structured mesh from MSC Software. It had been an honest fit for GreenDwell’s objectives since its accuracy and simulation time addressed the company’s design questions.

Since the workflow from the modeling tool into a 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 on an urban site. The location had several neighboring buildings that were obstructing ventilation.

Also, there have been existing large shade-giving trees on the location. one of the design objectives was to make sure that the children be ready to frolic around and play within the tree shade without having to depend on air conditioning.

Since the location was long and narrow, it had been challenging to work out the simplest possible building form that might allow the wind to flow through. The team ran the simulation, accounting for both present surrounding buildings also as for a future worst-case scenario where near-by empty plots are developed.

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 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 the time kindergarten building has been operational, the input from instructors and students' guardians are extremely positive. The environment at the school is genuinely not quite the same as what one might expect from an urban school.

Since it is cool and windy, the children truly enjoy and appreciate utilizing the space. Even on days when the 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.

CFD Solutions: scSTREAM

scSTREAM thermo-fluid software has serviced the electronics and architectural industries for thirty years. The ever-evolving software is characterized by its overwhelmingly user-friendly interfaces and high-speed processing. HeatDesigner is based on scSTREAM and is specially developed for the thermal design of electronics products. HeatDesigner provides physical functions required only for thermal design with its simple interfaces and powerful computing performance.
