“Could you provide remote consultancy for my home design for good ventilation ? The project is simple as follow:
I have a flat (In Egypt) with around 250 m2, I am in phase of start building the walls, and I need to design the sizes and locations of the windows/door to give the best natural ventilation, the items are already allocated as per attached, but I am consulting you as I bit the design was considering natural ventilation concepts.
Could you please let me approx how many hours It would take to check the design and give a consultation for the flat ?
Note: I am open to reconsider internal walls for better weather if they are blocking the cirulation.
The weather in Egypt is hot in Summer (35-45 C) and Cold in Winter (5-15)
I chose to use AAC-block for its advantages over the traditional building blocks (Better Heating/cooling, fire-resistance, Sound Resistance, ..)
The point is that My building is consists of flats so no gable rooftop, it is a traditional building with floors and each floor is a flat.
I will also for sure use Fans/AC in different areas based on your recommendation, but I am seeking to cut down my electrical bill, so that's why I choose AAC blocks and that's why I also seek Passive cooling/heating design if possible.
Could you please let me know what will be the deliverables during our consultancy ?

  • Designing/Positioning the windos/openings to enhance air flow and cross ventilation according to local climate and site

  • Recommending hybrid system while involving Fans/AC/.. .

  • Shading/blinds recommendations.

  • Hot stale air expelled design in Summer, and Maintining in Winter.

  • etc.“
