I already know and using ENVI-met simulation tool but i would like to be updated with other modeling tools that suits the outdoor micro-climate modeling and urban forms assessment
I believe that the ENVI-MET software remains the most used and the most efficient. In fact, it allows to simulate any microclimate environment. In addition the new version offers several interesting features. Furtheremore it can be used in a different arrchitectures of computers.
Dear Wesam El-Bardisy,
The ENVI-MET software represent at all the tool the most used In this field, in other way there exist other software such as CitySim Software.
I suggest you to see links in topic.

Dear Wesam,
I would like to know why you are searching for an alternative tool. I've been leading the development of Solene-microclimat that is almost only used by us but performs very well compared to Envi-met.
At present, we are writing a review paper and are quite unable to know exactly how envi-met calculates fluxes, what is for me the major limitation.
Regards
Marjorie
Dear Marjorie,
Thank you for your reply, i would like to know some alternatives for ENVI-met is really a good modeling tool, however, i am searching
_for less grid-size ( i would like to model grid less than 0.5 for more detailed analysis )
- calculate the overall energy consumption for building clusters without entering in the hassle of coupling with other tools such as design builder
- less simulation time and better visualization in interface and the outputs
Thank you Wesam, with solene-microclimat, we chose the grid but we only calculate the energy balance for 1 building.
There is citysim that could answer your requirments. There isn't a coupling with microclimate, but radiation is welle taken into account. One of my Ph.D student use it.
Regards
Marjorie
Dear Wesam,
We have coupled Solene with a mixed 1D-2D thermal model (SUSHI - Simulation in Urban Scene of Heat DIffusion) to compute heat exchanges and temperature distribution over roofs and facades at various spatial resolutions. The 1D model (based on thermal quadrupoles) is used for plain walls, whereas the 2D model (based on FE) is used in areas where thermal bridges are present.

Here is the link you can download the free trial version. Good continuation.

Dear Wesam,
I am following up on previous reponses Mohamed-Mourad Lafifi Marjorie Musy
If you want to evaluate urban forms at a large scale as well as calculate the energy consumption, you can indeed use the CitySim software. We have coupled it with CIM, to integrate the urban climate in the calculation of the energy demand. The advantage of this coupling is that you can run the simulations for one whole year, which is necessary for building design.
Both models are freely available for research purposes. Here are some links for the studies:

Consult RayMan and SkyHelios models which undertake exactly the microclimatic assessments you are seeking

You can try ENVI-Met, PALM4U as suggested before and also MISKAM or KLAM
CFD (e.g. Fluent) may help if you are interested in micro-scale wind environment.
There is a new method named CityFFD. We developed this model in our research group at Concordia Unievrsity. This model can simulate very large scale problems at city scale in a fast manner. The model is based on Fast Fluid Dynamics (Semi-Lagrangian) and has been developed by using GPU CUDA. If you need more information, you can see our recent papers and also contact me to provide you more inf.
Mohammad Mortezazadeh Dorostkar I checked the publications and they looked awesome. I guess however the model isn't accounting for the green nor the blue spaces fluxes and rather is built upon the surfaces temperatures. Also, I couldn't recognize which platform are you running the model on. Is it OpenFOAM, Fluent, etc..? Great work. Thanks for sharing!
