Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 9: “Sloped and Complex Green Roofs” by Richard Hayden

February 8, 2012 at 1:14 pm

Today we have the pleasure to air Richard Hayden’s video presentation “Sloped and Complex Green Roofs”  from our inaugural  2011 Greenroofs & Walls of the World™ Virtual Summit on and our GreenroofsTV channel on YouTube.

Dick is an extremely  knowledgeable  landscape architect with a quick and easy smile, and I’m sure you’ll not only enjoy his presentation but will certainly learn a lot as well with his years of experience at American Hydrotech.  He speaks about the unique challenges associated with unique building pitches and shapes, and highlights the Lace Elementary School; Tyner Interpretive Center; H2 Hotel; ASLA HQ;  Macallen Building;  Vancouver Convention Centre; and the Lincoln Center for the Performing Arts’ Hypar Pavilion, which we have featured as our Greenroof Project of the Week in honor of showing Dick’s video.

American Hydrotech has been one of‘s oldest and staunchest supporters and advertisers, and we are very happy that they sponsored our inaugural  2011 Greenroofs & Walls of the World™ Virtual Summit as our Emerald Sponsor.

Richard C. Hayden, RLA, ASLA, CLARB, is the Garden Roof Department Manager at American Hydrotech, Inc. Based in Chicago, Illinois, he’s been a practicing landscape architect for more than 30 years and has been involved in a wide variety of projects across the U.S.  He’s been involved in green roofs, green plazas and green infrastructure in his array of projects that include public and private buildings, bridges, streetscapes and large infrastructure projects.  American Hydrotech, Inc. ®, is a recognized leader in the development, production and distribution of premium waterproofing and roofing products since 1977.  Since its first green roof in 1996, American Hydrotech has been expanding its Garden Roof presence with more than 1,400 projects representing over 7 million sf of Garden Roof installations.

In Richard’s “Sloped and Complex Green Roofs” he proposes that no longer are green roofs relegated to the world of flat roofs.  Architects and designers are discovering the nearly unlimited design potential of incorporating green roofs as an integral part of the composition of the building.  From simple sloped roofs to complex combinations of curves and planes, green roofs are being blended with architecture in very unique ways.  This presentation outlines the challenges and solutions to helping architects and designers meet their design intent for their buildings. Examples of a variety of sloped green roofs from around the United States will be explored to outline the technical solutions that were developed by American Hydrotech to achieve the desired result.  Architects and designers will be able to see that their imagination is the only limiting factor in blending green into their designs.

GPW: Church Street Station

July 29, 2011 at 9:09 pm Project of the Week: 7/25/11
Church Street Station
Evanston, IL, USA
8,500  sf. Greenroof

Year: 2002
Owner: Focus Development
Location: Evanston, IL, USA
Building Type: Multi-Family Residential/Multi-Use
Type: Intensive
System: Single Source Provider
Size: 8,500 sq.ft.
Slope: 1.5%
Access: Accessible, Open to Public

Project Description & Details

When it planned to build the Church Street Station Condominiums, the building owner, Focus Development, added an important feature to the building – a Garden Roof – where condominium owners could go to get away from the bustle of daily life.  Installed on the 5th floor roof atop the residents’ parking structure alongside a beautiful pool and fitness room, this 8,500 sf Garden Roof not only adds natural beauty, it has proven a major selling advantage – a private oasis in the middle of downtown Evanston and mere moments away from occupants’ doorsteps.

Installed by Intrinsic Landscaping, the Garden Roof Assembly was provided by American Hydrotech and is based on time-tested components like the Monolithic Membrane 6125-EV waterproof membrane.   Birch, maple and evergreen trees, tall grasses, and flowering shrubs and perennials create a naturalistic backdrop to the lush lawn and beautiful arbors. The growing media depth in the lawn area is 8″, with the perimeter parapet in the range of 18″ deep. The irrigation is through pop up emitters.

Additional Info

Construction for Church Street Station began in May 2001, and first closings occurred in September, 2002.   The 17 story, 105-unit condominium development also has 17,000 square feet of ground floor retail space.  Located in the heart of downtown Evanston, the multi-use project includes an indoor swimming pool with outdoor sun deck, fitness center and parking.

The development has a prime attraction due to its proximity to public transportation with CTA and Metra stops across the street, in addition to the array of distinct shops and upscale restaurants within easy walking distance.

“Church Street Station features 18 floor plans among its 103 condo-miniums, including soft lofts, tower homes, deluxe tower homes, and duplex penthouses.   All homes feature one to three bedrooms, one to four baths, floor-to-ceiling windows, and private balconies or terraces.   The building also boasts a number of luxury high-rise amenities, including a doorperson, indoor pool, outdoor sun deck, fitness center, hospitality room, bike room, private storage lockers, and rooftop terrace with garden.” ~ Church Street Station Condominium Association.

And perhaps the coolest amenity is the lushly landscaped vegetative roof!

The developer decided on the greenroof system as an environmentally friendly response to the urban  heat island effect of increasing temperatures from this growing area.   The project is sold out and the retail is 80% leased.

The high quality and efficiency of the sytem chosen, the Garden Roof Assembly, by American Hydrotech, starts with their Monolithic Membrane 6125-EV waterproof membrane.   A seamless hot-applied rubberized asphalt membrane, MM6125-EV provides long-lasting protection and incorporates a minimum of 25% recycled materials.  The assembly also includes Floradrain FD40, which helps to recreate the plants’ natural growing environment on the roof.   Designed to retain moisture, irrigating the vegetation from the underside, Floradrain also channels excess water to drains.

In 2001 when the developer, Focus Development, decided to invest in their beautiful living roof, they said they were taking the lead from Chicago’s City Hall Pilot Greenroof, which had just installed theirs to show civic leadership earlier that year.
