Other LEUCs, such as the Dubai Electricity and Water Authority (DEWA), in the case of Dubai, may demand that this isolation equipment be located in a room at street level, directly accessible from the outside or in a completely separate building at the site property line. In other jurisdictions, the LEUC may require that the main isolation equipment (switchgear or ring-main units) be located as close as possible to the outside wall where the service enters the building. In some jurisdictions, the LEUC has no requirements for the main switch room at all, and it can be located anywhere within a basement area. Often, the location of this electrical room depends on the demands of the LEUC.Ī significant concern is that each LEUC has its own idiosyncrasies. The utility supply will enter the building from below grade and usually terminates in a main switch room. Ideally, the supplies are fed from multiple sub-stations to increase the reliability of the main electrical system. The LEUC supplies the building with medium-voltage power from one or more utility sub-stations. To successfully overcome these challenges, careful planning, collaboration with other professionals and coordination of systems are essential.įirst of all, every tall building is supplied with multiple sources of electricity, including feeds for normal power, usually supplied by the local electrical utility company (LEUC), and an emergency or standby source of power, usually supplied from on-site engine-generator sets. The complex electrical systems installed in these tall buildings present to the engineer a number of design challenges, including space constraints, limitations of physical structure and the integration of multiple systems. The other tower houses The Jumeirah Emirates Towers Hotel.
