This document presents analysis on the energy performance of the double skin facade for the Okhta Center tower in St. Petersburg. It summarizes findings from simulations of heating and cooling requirements based on 25-year average climate data. Key results include estimated annual heating needs of 27.62 GCAL/hr, lower than initial estimates. Optimizing the facade could reduce both heating and cooling needs. Further analysis is needed to optimize passive heat transfer and manage high buffer zone temperatures during warm periods.
