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.
