Indoor Thermal Comfort
Thermal comfort analysis is the modeling of how an occupant feels in the environment based on temperature.

Natural Ventilation
Technically, it is a type of ventilation which is realized by using air movements caused by wind pressure or temperature difference.

Data Centers
Data center cooling performance, airflow management and velocity-temperature distributions

Indoor analyses: space-based comfort, air quality and thermal safety
Short answer: Indoor analyses model a space’s thermal comfort, air quality, ventilation effectiveness and — in data centres — equipment cooling performance together with CFD. Alkazar runs this assessment using its own calculators (PsikroCalc, HavaCalc, KanalCalc, BoruCalc) alongside space-based CFD simulation.

- Natural Ventilation: Modelling the air movement created by wind pressure and temperature difference (buoyancy, cross-ventilation) as an input to design.
- Data Centre — Indoor CFD: Verifying rack-level airflow and temperature distribution in the white space (IT room) and grey space (critical support areas); the external-flow and climate-resilience dimensions are covered on the dedicated data-centre page.

Worked case: Sabancı Center Akbank
For Akbank’s office at Sabancı Center, visual comfort, thermal comfort and indoor air quality measurement and design support were provided together through Indoor Environmental Quality Consultancy — an example of how three indoor-analysis strands come together under one scope. At the recently renewed Akbank Headquarters, a comprehensive interior transformation of roughly 35,000 m² across 33 floors received CFD-based thermal comfort consultancy.
Process and deliverables
| Steps | Deliverables |
|---|---|
| Defining the space/building model and usage scenarios → identifying the relevant analysis (or analyses): thermal comfort / air quality / ventilation / data centre → CFD simulation → evaluating results against the relevant comfort criteria | Comfort and temperature/velocity distribution maps, parameter-based assessment, design recommendations where needed — details on the relevant service page |

Frequently asked questions
- What does indoor analyses cover?
- Three areas: thermal comfort and indoor air quality (on the Indoor Thermal Comfort page), natural ventilation, and white-space/grey-space CFD analyses in data centres. Each is detailed on its own service page.
- Is measurement also carried out, or only simulation?
- On the Sabancı Center Akbank project, visual comfort, thermal comfort and indoor air quality measurement and design support were provided together through Indoor Environmental Quality Consultancy, as stated on that project page; scope is set per project.
- Which calculators can be used for a quick pre-check?
- PsikroCalc (psychrometrics), HavaCalc (ASHRAE 62.1 fresh-air rate), KanalCalc (duct sizing) and BoruCalc (hydronic pipe sizing) — all four are free (Turkish-language tools).
- Are data centre analyses part of this page?
- The indoor CFD analyses of a data centre's white space (IT room) and grey space (critical support areas) are part of this family; the external-flow, transient-resilience and climate-risk dimensions are covered in full detail on the dedicated Data Center CFD and Thermal Safety Analytics page.
