- The first LEED certified building in the Czech Republic and one of the biggest office projects in Prague
- Formerly a contaminated site, cleaned up prior to construction by treating contaminated soil and reusing or removing existing waste
- Over 75% of construction waste diverted from landfill, including 10,000 m3 of concrete from earlier structures that was crushed and reused on site.
- Over 90% of building materials manufactured and sourced 800km from the site
- 20% reduction of water use within the building
- 50% reduction of water use for landscaping, achieved through water efficient landscaping and roof gardens, entirely watered by an automatic rainwater system
- 25% reduction in energy use, achieved thought comprehensive and holistic strategies pertaining:
- sophisticated air-conditioning system: during cold weather the cooling units can operate in heat pump mode to heat the building; and operable windows and valves allow for natural local or centrally controlled cooling during the summer.
- Automatic external sunshades reduce excessive natural light and sensors regulate indoor lighting according to the level of daylight, which reduces the building’s electricity consumption.
- Natural ventilation
- Automatic indoor environmental control system e.g. automatic external sunshades, that adjust accoding the levels of sunlight and provide glare control and daylight sensors, which are programme to turn the artificial lighting, when not needed
- 50% of building’s energy comes from renewable energy sources: CSOB have joined the Czech Green Energy programme, which ensures that a minimum of 50% of the building’s electricity requirements are met by renewable energy sources in the Czech Republic, including hydro-electric and wind power plants
- Green roof, planted with low-growing vegetation, trees and shrubs. This together with the climbing plants on the façade improve the heat-insulation properties of the building and reduce the urban heat island effect.
