A fast power demand response (DR) strategy involving both active and passive cold storages is presented. This control strategy provides an immediate and stepped power demand reduction through shutting chiller(s) down when requested. The results show that the power demand reduction and building...

A thorough assessment and diagnosis is critical for understating and enhancing building energy performance while most buildings cannot provide sufficient energy use data for a detailed diagnosis. This paper presents a multi-level energy performance diagnosis method for energy information-poor...

The low delta-T syndrome exists in many large primary–secondary chilled water systems, which results in the degradation of the system overall energy performance. This paper presents a method and a case study on diagnosing the low delta-T problem resulted from the deficit flow that frequently...
