Appendix A5_Summary of Analysis for Okhta Tower Facade Energy Performance

•
•
Richard D. Ochotorena
Richard D. Ochotorena

This document presents an analysis of the energy performance of the double skin facade for the Okhta Centre tower in St. Petersburg. It summarizes heating and cooling requirements based on 25-year average climate data, including wind speed, temperature, solar heat gain, and cloud cover. Charts are provided showing heating needs for buffer zones and offices from levels 6 to 72 and for atriums. The total estimated heating requirement of 27.62 GCAL/hr per day is less than the 46.18 GCAL/hr stated on the project website. The double skin facade provides an option to optimize energy consumption during cold seasons.
