Building-energy consumption constitutes a pivotal component of global energy systems, with the heating and cooling loads during operational phase being particularly significant. Substation building, as nodes in transmission transformation network, deserve attention for their building-operating loads. This study investigates substation operation severe cold climates. By integrating simulations one-factor-at-a-time orthogonal multivariate analyses, optimization strategies under key influencing factors are systematically explored. The impact analysis identifies following order influence magnitude on total loads: indoor equipment heat generation, ventilation rate, roof U-value, exterior wall window U-value. heating- cooling-load characteristics exhibit distinct patterns depending generation. building load can be reduced by 61.23 per cent multifactor optimal de-sign conditions, highlighting critical role systemic design coordination. provides case reference efficient substations, especially where significant changes occur, highlights importance controlling sources to achieve efficiency.
