ENGINEERING TOOLS & CALCULATORS
Alkazar’s engineering tools grew out of our CFD (computational fluid dynamics), building-physics and climate-analytics practice — each tool below shares part of the same methodology we use on live projects, packaged as a free pre-sizing calculator or an interactive example. Most tools are free and run directly in your browser with no sign-up: wind profile, U-value (heat transfer coefficient), psychrometrics, duct and pipe sizing, and ASHRAE 62.1 fresh-air calculations all fall in this group. Professional modules that carry a multi-parameter, proprietary methodology — such as WindCalc — are available through an UrClimate Tailor subscription. The tools under climate risk and meteorology present interactive examples drawn from finished analyses. Every result here is for pre-sizing and orientation only; it is not a substitute for project-specific CFD analysis, site measurement or engineering consultancy — when your project needs a binding result, reach out through the matching service page below.
Badge key: FREE = use directly, no sign-up. Tailor Subscription = unlocked with your UrClimate Tailor account. TR/EN = the tool’s interface language.
Wind Engineering
Wind Profile Calculator
Calculates wind speed and dynamic pressure versus height for standard roughness classes (log-law profile).
EN 1991-1-4 practice
Data Center
Bypass & Recirculation Loss Analysis
Estimates the annual hidden cost of exhaust-air recirculation at outdoor units — capacity derating and PUE degradation.
PUE / derating
Climate Risk & Meteorology
COP31 Antalya Weather & Climate Risk Analysis
Integrated meteorological risk analysis for COP31 Antalya from 46 years of ERA5 data (1980–2025), with a day-by-day risk score and charts.
ERA5 1980–2025
Professional modules live in UrClimate Tailor
Multi-parameter modules with proprietary methodology, like WindCalc, unlock with an UrClimate Tailor subscription; the calculation runs in Tailor while this page keeps its search ranking and context.
Turkish-language tools
These tools run in Turkish only and don’t yet have an English interface. They’re listed here for completeness — the calculation and any on-page labels are in Turkish.

The tools on this page are for engineering pre-sizing and orientation; they do not replace project sign-off, site measurement or CFD analysis. We recommend verifying results against the relevant standard, and confirming with Alkazar’s engineering team, before using them in a final design.
