Leed Gold Certificate for H2O

In recognition of its high Green Building standards, the H2O was awarded the LEED Gold Pre-certificate. The office property designed by WÖHR + BAUER convinced the committee of the world’s most successful certification system for sustainable building with its high energy efficiency, low water consumption and use of ecological materials.

The LEED certification demonstrates that the H2O uses natural resources exceptionally and therefore significantly reduces demand for primary energy. Environmental protection also provides an economic pay off. The operating costs of the H2O are up to three times lower than in conventional new buildings. Tenants benefit from low utility costs and enjoy a higher level of comfort in the workplace.

With the tagline “Natural Working Place”, it is no surprise that water is a key element for improving the ambience in the H2O, using an optimal energy temperature control system. In the future, more than half of the heating in the H2O will be generated by water from near-ground geothermal sources. According to experts, the trend towards resources-saving environmental technology, such as daylight-dependent lighting control, geothermal energy and rainwater harvesting will gain considerable importance in years to come. For many companies, an ecological property is also of value to their CSR guidelines.

The LEED (Leadership in Environmental & Energy Design) building certification system is the standard for high-quality ecological buildings. It was developed by the non-profit organisation USGBC (U.S. Green Building Council). The certification is based on the American standards in accordance with ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers, Inc.) requirements.

The following categories are rated:

  • Building location and exterior space and its impact on the environment
  • Water consumption in the use phase
  • Power consumption in the use phase. This includes heating, cooling and lighting systems, as well as the use of renewable energy
  • Building materials used. The focus here lies on the use of local, renewable or recycled materials.
  • Health and comfort in the building. This includes reduction of emissions while simultaneously increasing the workplace quality by enhanced fresh air supply and natural lighting of working areas.
  • Special innovations
