Project report

The Philadelphian Condominiums complex was built in the 1960’s and is situated just opposite the Philadelphia Museum of Art. Recently the unsightly, poor draining and leaking black roof has been renovated and turned into attractive greenery. As Philadelphia’s old sewer system is undersized for heavy rain events, Philadelphia has developed an innovative 25-year storm water plan. Among other measures it heavily promotes green roofs by providing substantial incentives to condominium property owners for the implementation of functional Stormwater Management Projects (SMPs) and by reducing their monthly stormwater management service charges. The Condo Association in turn has gained an increased property value and energy efficiency plus a 25 year leak free warranty for their roof.

Besides the reduction of water runoff, the green roof also enhances the visual appearance of the surface.
Inspection chambers allow easy access to roof outlets.
Most of the roof area was planted with pre-cultivated plant mats

Extensive G�� “Ornamental Sedum” – Sophisticated Design and Individual Character

Extensive G��s call for plant communities that can easily deal with sun, wind and drought. The system build-up “Ornamental Sedum” leads to an extensive G�� with sophisticated design and individual character. The growing medium has a minimum depth of 2.75 in and the vegetation consists of various species which provide a long blooming period and set different accents throughout the vegetation period.

Water and nutrients are mostly supplied through natural processes. Rainfall collects in the Floradrain® storage cells and roots are provided with water through diffusion. Water is also stored in the protection mat. Excess water is drained away by the Floradrain® element.

Sedum species and other perennials are primarily used as a ground cover. The vegetation of “Ornamental Sedum” is obtained by root ball plants. Hand-planting ensures that the design agrees with the landscaping drawings.

Technical Data
Build-up height	ca. 4 in.
Weight, saturated	ca. 22 lbs/sq. ft.
Water storage capacity	ca. 0.9 gal/sq. ft
