Building energy demand response simulation for an office tower in New York

This paper presents a building energy simulation study of the impact of electrical peak demand reduction strategies in a large office tower in New York that has extensive use of daylight responsive dimmable ballasts, and under floor air distribution systems (UFAD). The complexity and large size of the building imposed careful simplification of the simulated geometry in order to make the simulations and results analysis manageable. The simulations were used to predict the building energy demand profile and test different control strategies that minimize degradation of indoor conditions while achieving a significant and stable demand reduction during four-hour midday periods in the warmer months of the year.
