Bloomberg’s new European Headquarters in London opened today, and has been billed as the most sustainable building in the world. Designed by Foster + Partners, the building boasts a multitude of sustainability features and has been awarded a BREEAM score of 98.5 per cent against its criteria – the highest ever achieved so far by a major office development. It is designed to use 73 per cent less water and 35 per cent less energy than a standard office building.
SWECO, engineering environment and design consultants, were appointed by Bloomberg in 2010 to provide building services consultancy, including BREEAM support for the project. SWECO used the IES Virtual Environment (IESVE) to conduct energy modelling and generate an Energy Performance Certificate (EPC) for the building.
Some of the buildings most sustainable features include:
- Integrated Ceiling Panels: Bespoke integrated ceiling panels combine heating, cooling, lighting and acoustic functions in an innovative petal-leaf design. The system, which incorporates 500,000 LED lights, uses 40 percent less energy than a typical fluorescent office lighting system.
- Natural Ventilation: When ambient weather conditions are temperate, the building’s distinctive bronze blades can open and close, allowing the building to operate in a “breathable” natural ventilation mode. Reducing dependency on mechanical ventilation and cooling equipment significantly reduces energy consumption.
- Smart Airflow: Smart CO2 sensing controls allow air to be distributed according to the approximate number of people occupying each zone of the building at any given time. The ability to dynamically adjust airflow in response to occupancy hours and patterns is expected to save 600-750 MWhr of power per annum, reducing CO2 emissions by approximately 300 metric tonnes each year.
- Combined Heat & Power: An on-site Combined Heat and Power (CHP) generation centre supplies heat and power in a single, efficient system with reduced carbon emissions. Waste heat generated from this process is recycled for cooling and heating and, in use, is expected to save 500-750 metric tonnes of CO2 each year.
The IESVE has been used to help create some of the most sustainable and renowned buildings in the world, including: the Royal London Hospital, Dubai Opera House, Four Seasons Hotel, New York and the Golden One Center, California.
