GREEN ROOF SHADING PROBLEM

A concern raised was could a sedum prosper on a shaded
roof? The roof is almost entirely shaded from October
through March and receives only a few hours of direct sunlight daily in summer. Oscar Warmerdam, of Sempergreen,
was called to assess the sunlight conditions and make plant
recommendations. At the next Board Meeting he reassured
the Owners and SDA that with the proper mix sedum plants
would thrive. A plant list was specifically developed with
selected varieties of sedum supplied as mats, sedum plugs,
cuttings and larger ornamental sedum. Sempergreen managed
the establishment of the sedum for two years and as of April
2017 the plants are performing well.

PHILADELPHIA WATER INCENTIVES
AND TAX PROGRAMS

The last remaining hurdle was the overall cost of the system.
We understood green infrastructure incentives from seminars
given by Erin Williams of Philadelphia Water. The Philadelphian would be eligible for a reduction in their stormwater
rates by adding green infrastructure. The impervious area reduction resulted in a savings of over $900 per year or $29,000
over the warranted roof life. The Philadelphian would also be
eligible for a SMIP Grant (Stormwater Management Incentive
Program). The SMIP Grant application required the Owner
to commission a "Stormwater Plan" for the entire property.
General Manager Frank Bonom, hired a civil engineer to
commission the stormwater plan and to complete the SMIP
grant application earning a Grant award of $25,000.00. The
combined stormwater savings, along with decrease in energy
costs, increased membrane life expectancy, and substantial increases in property value for green roof facing condominiums,
provided the needed leverage for the Green Committee to
convince the Owners Association Board to move ahead with
the project.

RECEIVED THE ONLY ENERGY STAR
RECOGNITION FOR MULTI-FAMILY

ENGINEERING, PROCUREMENT
AND ESTABLISHMENT

The Board approved the green roof concept in August 2014. The
final plans included changes to the preliminary plan to accommodate
window washing scaffolds and balconies on the project. This
resulting design extended the green roof to the perimeter edge to
comply with the SMIP Grant requirement of 70% coverage.
The installed Flex PVC roof system included an International
Leak Detection (ILD), Electric Field Vector Mapping (EFVM) vector mapping grid beneath the PVC membrane and the system was
tested for defects prior to covering with a green roof. The green roof
installation was done in March and April of 2015. Before the installation of the green roof the perimeter paver system was installed above
the Floradrain™ drainage panels on a pea gravel base. The green
roof system can store up to 1.8 gallons of stormwater per square foot.
The substantial completion of The Philadelphian green roof project
occurred on Earth Day 2015 and was featured on the front page of
the Philadelphia Inquirer Newspaper.

CONCLUSIONS

The Philadelphian green roof has grown beautifully in its first
two years. The best evidence of the success of this project is the
pride and affection shown by the Owners. The Philadelphian,
originally built in 1964, just received the only Energy Star "Labeled
Building and Plants" recognition for multi-family housing 2017 in
Pennsylvania. Only six multi-residential properties in Pennsylvania
have ever received this prestigious recognition. The green roof
replacement was factored into the building assessment and played a
significant role. Philadelphian Owners Association and their Green
Committee should be praised for having the foresight and compassion to consider how their building impacts energy consumption
and water management for the City of Philadelphia.
William F. Foley is a green roof veteran who has taught the Green
Roof Design and Installation course for over 14 years.
