- Project Period:
- 01/10/2016 To 30/09/2017
- Project Description:
The Green Mark Non-residential Building Version 2015 has a newly developed framework to simulate, analyse and assess the thermal comfort conditions within certain selected habitable spaces that are commonly found and are important to non-residential buildings. In the development of the Green Mark Residential Building Version 2016, a similar framework is required for the internal spaces of dwelling units. It is envisaged that this framework for residential buildings should be robust, yet cost effective and quick to set up, simulate, analyse and assess.
- Lead Organization:
- Building System & Diagnostics Pte Ltd (BSD)
- Project Impact
- 1) Time saving (Decoupled Unit vs. Micro Level) as high as 60%2) Reduction in turnaround time translates to cost saving in consultancy fee and wider adoption of CFD3) Adoption of assisted ventilation (in Step 3) welcomed by industry

- Project status:
- On-Going Completed Terminated
- Project Outcomes:
-
- The goal of the project is to develop a new CFD framework (required for modeling the internal spaces of dwelling units) which is robust, cost effective, quick to setup, simulate, analyze and assess.
- The developed new CFD framework has managed to attain the desired time saving. The reduction in the simulation turnaround time (of decoupled unit level vs. micro level CFD simulations), pending on the size and complexity of the building project, can be as high as 60%.
- A large building project, when performed under the new CFD framework, tends to achieve a bigger saving in simulation turnaround time, compared to a smaller building project in size.
- A reduction in turnaround time translates to cost saving in consultancy fee, due to a lower computational runtime and manpower hours needed.
