Dubai Electricity and Water Authority (DEWA) says its new headquarters will be the tallest, largest, and ‘smartest’ net zero energy building in the world when it is completed in 2019. The state-run electricity and water utility says the total built area of the Al-Sheraa building will be more than 13.9 ha (34 acres). The building will feature more than 1.65 ha (4.1 acres) of photovoltaic solar panels. Total renewable energy generated by the building will be more than 5,400 MWh annually. Al-Sheraa’s design was inspired by the traditional houses in the UAE, where enclosed spaces overlook an open courtyard. The courtyard will be the focal point and most prominent feature of the building. To reduce heat in the open courtyard, a ‘sail’ will be used to provide shade. Natural light during the day will stream through specific openings in the sail, giving sufficient light without the associated heat.
