Green Roof in Ottawa

Image from Google Earth

From Metro News:

Ontario Completes Ottawa Courthouse Green Roof (2012)
"A new green roof at the Ottawa Courthouse will reduce energy costs, improve air quality and help Ontario meet its long-term energy conservation goals.  (The roof's green space is bigger than four hockey rinks put together, or one football field.) 
The Ottawa Courthouse's green roof is a living landscape that supports 60 varieties of plants and protects the building's structure from the elements. There are 26 separate green roofs spanning multiple elevations, for a total of 70,000 square feet of green space that will help keep Ottawa's air clean. 
While a conventional roof lasts only 20 to 25 years, green roofs last at least twice as long. The new green roof will save $23,000 a year in energy costs by reducing summer cooling and winter heat loss by 26 per cent."

I found this after reading about Ottawa investing in solar energy on their municipal buildings:

Ottawa gets green with solar energy project (Metro News, September 2016)

"Eight municipal buildings now equipped with solar panels."

Another great public indoor greenspace in Ottawa


New Currency Museum (Bank of Canada)
Bank and Wellington - access from Sparks Street

One of the indoor atriums that I've always found lovely is the Bank of Canada Garden Court Atrium (that was accessed from the Spark Street side).  Now that the buildings are being renovated, I was wondering what would happen to it.  It was such a lush, relaxing spot for people to enjoy - especially in the winter!  Remember the space where you could see the Yap stone?  It was also a popular spot for wedding photos during the winter months.

The Currency Museum blog explains that the new museum will be in the lower level but it doesn't provide information on how the main floor will be transformed.

From the website: "It is there, beneath the plaza at Bank and Wellington Streets, that the new Museum is planned to be - taking up the east end of the huge former cafeteria including the glass ceilinged ‘waterfall room’, and the large common area where staff events took place as recently as last summer."

The courtyard space on Bank Street looks really wonderful and provides some great public seating - I was wondering what those strange imposing triangle structures they were building in that space were.




Sadly upon doing some further online research, it seems that the Bank of Canada IS considering eliminating this atrium for reasons of safety and space requirements. This 2014 online article from The Cultural Landscape Foundation shares the full story and provides some thought on the need to save this atrium and preserve the architectural integrity and history of the design.

Indoor Atriums in the City (Ottawa)

Here is a list of great atriums to visit in the winter to get your kick of green and light (especially if it's a sunny day!):

(Temporarily Closed) Sunlife Financial building (99 Bank Street)

There are many entrances to this atrium: through the Starbucks, from all street sides including O'Conner and from its official address on 99 Bank.  Depending on where you enter head towards the center where you'll find a large courtyard area including an elevated spot with a waterfall which gives visitors a great respite from the usual city experience (noise, grey, packed sidewalks).  Great retreat in the winter but it does get busy during lunch hours.

Minto Place atrium (407 Laurier Avenue W.)

This indoor spot is well-known for its green living wall.  A popular place with the downtown lunch crowd (so again it can be quite busy mid-day) who likely come for the light and airy peaceful space.  Come on a sunny day as you will get the maximum benefit from the vast glass ceiling and enjoy the large tropical trees placed strategically around the courtyard.  There is access from all sides of the buildings and the atrium is found in the west end.

Photo link



C.D. Howe building (240 Sparks Street)

Inside this popular seventies mall (who remembers shopping at "240 Sparks" and/or going to the movie theatre here?) you can find a small courtyard downstairs with tables nestled beside living trees.  It has undergone a renovation in the past couple of years but still includes both the "Bright" Tree Court and a "Relaxing" Waterfall court.  Some of the anchor stores have moved out including L.C.B.O. and Holtz.  There is access from all sides including Queen Street, Bank Street and even along the Sparks Street mall.  It also has a green roof that has been opened to the public on past Doors Open events.

Greenhouses in Ottawa (to get your plant fix this winter)


As the weather turns colder and winter starts whispering about its arrival, thoughts turn to warmer climes and tropical getaways!  If you can't get away this winter, here are a couple of places to visit to warm yourself inside and out.  The tropical floral scents alone can elevate your mood:

Tropical Greenhouse (Arboretum) - Free Admission
Maple Drive

This greenhouse "has been recently renewed and replanted with a larger, more diverse collection. The elegant octagonal structure was originally built at Major's Hill Park in downtown Ottawa and moved to the Farm in 1938 to be used for horticultural research. Now a heritage building, it became a tropical garden open to the public in the 1970s."

Open Monday to Friday, 9 am to 4 pm; Sunday 10 am to 4 pm; closed Saturday.


Carleton Greenhouses - Free Admission
Nesbitt Biology Building

This facility is used for research, teaching and display to the general public. The greenhouses hold comprehensive plant collection of several thousand specimens ranging from popular crop species such as corn, soybean, papaya, banana and sugarcane to some quite unusual desert specimens.

Open Monday to Friday, 9 am to 4 pm

Oldest plant: Ponderosa Lemon (California hybrid), 33 years old
Biggest flower: Sun and Sand Hibiscus (Australia): 22 cm wide
Tallest plant: Chorisia speciosa (floss silk tree): 7 metres


Rideau Hall Greenhouses - Free Admission (when open to the public)

The Governor General's greenhouses are occasionally open to the public during special events (not during regular tours).  They were open as part of the Savour Fall event this year (2015) and in 2013 they were open as part of a Garden Gathering event.  Perhaps they might see the benefit of offering a weekend "doors open" to the public in the dead of winter?  ;  )


I'll also be adding to the blog some great indoor atrium recommendations that are accessible to the public - stay tuned!

Time to Frog Proof your Yard this Spring (swimming pools and window wells)

From an old 2009 Ottawa Citizen Article worth repeating:
The lives of tens of thousands of frogs, toads and salamanders could be saved each year if homeowners made a few simple changes to their homes and yards, says an Ottawa biologist.  Dan Brunton said backyard swimming pools are particularly deadly, and he has found up to 10 dead amphibians in the filter of his neighbour's pool before.  "The simple thing was they just couldn't get out," Brunton said.  "There's a wonderful commercial opportunity in here. Somebody make a nice little floaty ramp. You just leave it there and the critters climb out of your pool every morning."  A green frog trapped in the filter earlier this week was luckier than most — it was still alive when Brunton visited the pool to demonstrate the problem to a CBC reporter this week. 
While Brunton was renovating his home recently, he discovered another problem for amphibians — window wells. "The day these were put in two toads were found dead the following morning," he said, pointing at his own below-grade basement windows.  Brunton has now built gravel slopes in the wells so toads and other critters can climb out — something he encourages other homeowners to do.  "Since we've put this simple, simple little ramp in there, not one more animal has died in this thing." 
Fraser Veitch, a spokesperson for Benson Pools, a company that sells pool equipment and services, said it's fairly common for frogs to get trapped in pools, but people aren't always sure what to do when it happens.

Someone has now created that device to rescue frogs (and other animals including mice) from pools called the Frog Log. Here is a You Tube video showing the product in action: Frog Log (U.S. Company)

Slow Spread Sink (Sonoma Valley)


Best land management practices for storm water runoff.

The idea is to slow water runoff down - permeable surfaces work better and this can be applied not only to the ground but also roofs (that have impermeable surfaces).  Spread it around via rain barrels, french drains and other methods such as vegetated slopes and various gardens.  You don't want water to immediately be directed to pipes and culverts off your property.  Finally: let it sink!  Water can erode if there is not enough greenscaping - bare ground can be an issue just like pavement.  Use gravity, include swales and rain gardens and provide some xeriscaping on higher grounds.

This guide by Sonoma Valley on beneficial stormwater management is very comprehensive and provides lots of tips to homeowners and landowners.

Rockcliffe Lands Redevelopment - Part 5


DEVELOPMENT GUIDELINES

Ideas, policy and guidelines are all good.  We bandy around the words "sustainable", "green" and "resilient" but how do these words, these principals actually become groundtruthed and implemented?  How do you ensure that once you have interested developers, that they follow your vision and implement a development that reflects green design and construction? 

Many cities may have policy goals around this language to achieve in their Official Plans, Transportation and Greenspace Master Plans and Environmental Strategies but until these policies and values filter into the actual day-to-day operating principals and procedures of a municipality there is no way to guarantee that they will be implemented.

One method of encouraging this is to have these types of policies integrated into land development IMPLEMENTATION strategies.  These strategies will ensure that development can meet goals of 33% tree coverage, 50% green roof and walls, 75% native plant species, etc.  This can be done through Development Review Checklists (with biophilic goals outlined), bonusing and reduced development charges and LEED certification.

Waterfront Toronto development is one example of how this can be done.  The Waterfront Toronto has not only a Sustainability Framework but also Minimum Green Building Requirements which will "ensure that all new buildings along the waterfront are efficient in their use of resources and take advantage of new approaches and technologies to deliver a positive impact on the surrounding air, land and water".  For this development, "Twenty-five percent of the waterfront revitalization area is reserved for parks and open spaces." 

For Rockcliffe Lands, there needs to be as much thought put into a Framework, Guidelines and Implementation as there is for the Design Plan of this redevelopment.  Collaboration with both the City of Ottawa and the National Capital Commission are essential for this redevelopment to succeed.  Incentive programming should go hand in hand with guidelines so that this type of development is attractive to developers.  Specifically, what needs to be considered are:

Municipal Design Guidelines for Rockcliffe Lands:

- Green bus stops for onsite stormwater retention
- Native public gardens with both bee condos and insect hotels
- All public buildings Leeds Platinum with storm water retention onsite
- Natural playgrounds - playscapes (already in Ottawa)
- Dark Skies Lighting (already in Ottawa)
- Green Alleys (potential pedestrian/bicycle corridors)
- Native tree nursery (including Maples, Elms and "Champlain" Burr Oak)
- Bioswales as natural fencing between properties
- Good tree pit design (for trees that are bordered by concrete)
- Better standards for minimum soil volume for street trees


Private Development Guidelines for Rockcliffe Lands:

- LEEDS Platinum for all private development including:
- green paving technology and/or permeable pavement (already in Ottawa)
- green roofs and green walls for onsite stormwater retention and cleaner air
- bird safe building design - as found in Toronto (discourage glass condos)
- tree canopy coverage and landscape best practices (already in Ottawa at EQuilibrium)
- supportive by-laws for naturalized gardens

Construction Guidelines for Rockcliffe Lands:

- Current tree protection during construction (from Westside Action)
"No grade change, storage of materials or equipment permitted with this Tree Protection Zone.  Tree protection barrier must not be removed without the written authorization... Urban Forestry Services."

Root damage, trunk/bark damage, soil compaction and other activities from construction such as exhaust fumes from equipment can all compromise the health of a tree.  Even if the tree does not seem to suffer during the time of construction, there may be enough damage that the tree's ability to survive over a longer period of time may be weakened.
- Structural earth for all new street trees (from Westside Action)


HONOUR ALGONQUIN LANDS

This redevelopment includes identifying ways in which the Algonquin presence can be reflected on the Rockcliffe lands. "The history and connection of the Algonquin People with the Rockcliffe lands may be recognized through: installation of commemorative elements design of park spaces naming of streets, etc. Through the Consultation Working Group, Canada Lands Company and the AOO will jointly coordinate public unveilings of these initiatives. CLC recognizes that a commemorative opportunity on parkland overlooking the Ottawa River is of particular significance and interest to the AOO."  A site that honours and protects the native species (both flora and fauna) and allows for them to continue to flourish would be a great way to commemorate the First Nations People.

Involvement with the First Nations (through the Wabano Centre perhaps?) could also include leading the new neighborhood in efforts to connect with the land after the development.  This could include tree plantings, nut-harvests, tracking and living off the land workshops and even managing the tree nursery!

And one last thought - shouldn't the naming of the this new development reflect its aboriginal heritage?  Prior to the 17th century when this land belonged to the Algonquin people was there a name for it or could it be named after a prominent figure in either the Algonquin people's past or someone who should currently be honoured?  This is a great opportunity to ensure that this site will be forever recognized as Algonquin lands.

the greening of Chicago


Chicago's Mayor on Top of Green Roof - Image Source

First there was the City Hall's Rooftop Garden (in 2001) and the Green Roof Grant Program which provided grants to both big and small buildings in both the residential and commercial sectors.  By 2008, Chicago was the leading city in the U.S. with the most green roofs according to Green Roofs for Healthy Cities' Annual Green Roof Industry Survey.

Next it was the city's Nature and Wildlife Plan (in 2006) along with a Nature Areas Directory which listed more than 4,800 acres of prairies, savannas, dunes, woodlands, wetlands and potential restoration areas at 98 sites throughout the city. This plan "established a framework to protect and expand ecosystems for the benefit of wildlife and people."

As a follow-up in 2007, Chicago initiated its Green Alley Program which addressed the municipalities infrastructure issues.  The program introduced permeable pavement, bioswales and encouraged residents to consider rain gardens and purchasing rain barrels.

And then after that it was an Urban Forest Agenda in 2009 which would work hand in hand with the already established Nature and Wildlife Plan.  The goal here was to strengthen the urban tree inventory that was already in place and to enhance it with more trees, green infrastructure linking parks and creating programs to enlist local citizens to play a part in their street and park trees.

Now it's the 606 - Chicago's answer to NYC's High Line and the Burnham Wildlife Corridor along the shore of Lake Michigan. 


Present Day 606 - Image Source

First of all the 606, which will ultimately dwarf the New York City's elevated park, will be 2.7 miles long (the High Line is 1 mile) and will encompass 13 acres of land (adding five new parks).  It will connect four neighborhoods in the northwest end of the city.  One other difference to the High Line is that bicyclists will be accommodated on the 606 (or Bloomingdale Trail) whereas only pedestrians are allowed on the High Line.

For the Burnham Wildlife Corridor, located on the city's south side, the Chicago Park District enlisted thousands of volunteers to plant 125,000 trees and shrubs this summer which will provide a resting area for the 5 million birds that migrate through the city every spring and fall.  Many of them, with no place to land, found themselves colliding with the glass highrises downtown. This project will help ensure the safety of Chicago's avian visitors.

Constructed Wetland for Wastewater (Washington D.C.)

The Sidwell Friends Middle School in Washington D.C. has gained international recognition as the first LEED Platinum K-12 school building in the world built in 2006.

"Its green features include a constructed wetland that treats wastewater on site, recycled building materials (such as reclaimed wine caskets to make the building's skin), three green roofs (that provide habitat, reduce urban heat island effect and insulate), sunshades, solar chimneys (which enhance natural ventilation), and rooftop photovoltaic panels (that provide for all the school's electrical needs)."

More on the Constructed Wetland:

"Constructed wetlands use less energy to process waste than traditional municipal systems while creating habitats for plant and animal life. After first flowing through a treatment tank to remove solids, wastewater is treated using biological processes. Aquatic plants, water, microorganisms, sun, soil, sand, and air filter and clean the water. The process is completed with additional filtration of particulates and an ultra violet (UV) filter. The constructed wetland behind the Middle School building treats wastewater to the same standards as the city’s municipal system but due to current health codes, the water is reused only in the toilets and urinals. Models show that the building uses 93% less District water by treating our sewage in the wetland and reusing the water, as well as through water-efficient landscaping"

Milwaukee Avenue Green Development Corridor (Chicago)


Great greening the city project in the states (with a focus on reducing area flooding) - they are even talking bioswales! 

From the website:

In 2012, residents and business owners along Milwaukee Avenue between Kimball and California will be eligible to apply for funding to support property improvements that reduce neighborhood flooding, protect Chicago’s waterways, and make Milwaukee Avenue one of the most environmentally friendly blocks in Chicago. The Illinois Environment Protection Agency has awarded a $200,000 Green Infrastructure Grant to help finance green, water-saving projects along the entire corridor, such as green roofs, permeable pavers, rain barrels, and rain gardens. The Milwaukee Avenue Green Development Corridor is a joint project led by the City of Chicago and Ald. Rey ColĂ³n (35th Ward), funded by the Illinois Environmental Protection Agency, and supported by Metropolitan Planning Council and Chicago Community Loan Fund.

forward to nature

This movement isn’t about “going back to nature,” but going forward to nature.
Participants include: traditional conservationists; proponents and producers of alternative energy; physicians (particularly pediatricians) who prescribe time in natural areas and green exercise to patients; ecopsychologists and wilderness therapy professionals; park professionals who help families fulfill their “park prescriptions”; public health professionals and urban designers who work to increase the number of natural amenities near where we live.
Other participants are citizen naturalists salvaging threatened natural habitats and creating new ones; community gardeners and urban farmers; organic farmers and “vanguard ranchers” who restore as they harvest; urban wildscapers replacing suburban yards with native species; nature-aware champions of walkable cities and active living; deep green design professionals, including biophilic architects, developers, urban planners and therapeutic landscapers who transform homes, workplaces, suburbs and city neighborhoods – potentially whole cities and their transportation systems – into restorative regions that reconnect us to nature.

dark skies lighting


We hear about light pollution and how not only is it wasteful but also how it affects wildlife (nocturnal and those that migrate at night).  Here's a "Cool Green Feature" in Tartan's new development in Barrhaven called Havencourt (taken from their website):

Dark Skies Street Lighting
The purpose of streetlights is to light streets and sidewalks, not to block out views on starry nights. Havencourt will feature innovative downward directed street lighting—focusing the light where it’s needed. Get out your telescopes!

Street Canyon Ivy

Here's a link to a new study that suggests that ivy growing on walls may be better than street trees in cleaning the air in "street canyon" situations.  (Street canyons are roads surrounded by tall buildings, where air tends to linger.)

Here's more from the website:

"The researchers ran computer simulations to determine how green walls and roofs might affect pollutant concentrations at street level. Adding plants to walls would cut nitrogen dioxide levels by 15 percent and small particulate matter by 23 percent, the authors estimate. In areas with little wind, those numbers could reach 40 and 60 percent. Green roofs didn’t perform as well because they don’t directly affect the air near the street. 

Trees also help clean the air, but they can keep street-level air from mixing with the air above. At low to medium pollutant levels, planting trees will still reduce air pollution, the team predicts. If a city is very polluted, however, trees could actually increase nitrogen dioxide levels near the street."

Biocentric Cities: constructed (sewage treatment) wetlands


In my first semester Ecology and Environment text book, this picture of John Todd's "neighborhood sewage treatment facility" is an incredible design for a biocentric city.  I love that it's shown right against a sidewalk in between pedestrians and the street.

The description reads: "Water trickling through the containers of aquatic plants is cleaned and purified by biological processes.  Under optimal conditions, both odours and costs are minimal."  John Todd and his partner Nancy Jack Todd run Ocean Arks International.  Some of their other design concepts show how these systems "harnesses the biological processes that operate in nature within the form of an engineered treatment system to successfully meet discharge standards and permitting requirements"  and they are easily integrated into cityscapes.  Follow the link to see the concepts: "sustainable water management".

Here's an article on these living eco- machines: "Clean Green Waste-water Recycling" from Inhabit:
"Converting sewer sludge to fresh water is no easy job; traditional treatment plants consume massive amounts of money, energy, and resources. John Todd’s innovative solutions for waste-water management re-envision the process as an eco-conscious endeavor, conserving water and reducing overall treatment costs with minimal sludge disposal, water purchases, sewer surcharges, and chemical use."
_________________________

D & C's Biocentric Cities post is a monthly post that features options for energy and heating systems that would reduce our demand on natural and non-renewable resources outside the city (or in this one case - save energy).  A city's consumption is many times its city limit size and impacts nature that we don't even see. My hope is that a city can produce its own energy, heat and clean water within its city boundaries.

Skyscrapers for birds



Image from Richard Register's ecocities - Rebuilding Cities in Balance with Nature.

While the book focuses more on urban design, sustainable transportation and energy alternatives, there are some brief mentions of design to support nature. I loved this image (from page 123) showing a "birdhouse" in the city - a skyscraper designed for birds only (no people allowed)! Those two "dots" down in the right hand corner? Two people amazed by the building!

roof top garden in georgetown

An Urban Meadow: Georgetown's Hidden Rooftop Garden

- Garden in the Sky -
High above the bustle of Georgetown, an unusual rooftop offers condo residents a prairie of their own.

By Adrian Higgins, Washington Post
Sunday, September 20, 2009

Tom Carroll pulls up the birdsong application on his iPhone, summons the call of a song sparrow and points the device to the meadow that starts about 20 feet from his home.

Sure enough, after a minute or two, an actual song sparrow starts calling back to the digital one. This might be little more than an endearing party trick if Carroll and his wife, Dora Marcus, lived on the edge of a field in, say, upper Montgomery County. But they live a little farther downstream on the Potomac River, in the shadow of Key Bridge. The meadow, perhaps Washington's greatest secret garden, is perched atop a Pepco electrical substation on the Georgetown waterfront.

The straw-colored flower heads of a grass called calamagrostis are just visible for the most observant of motorists on the Whitehurst Freeway, and pedestrians on Key Bridge might glance back to see the fuzzy-topped brick substation, but there is no real public vantage point to view the full sweep of this prairie in the sky. This paradox is heightened during rush hour, when the freeway, Key Bridge and M Street NW are filled with weary drivers unaware of the meadow floating above them.

The grasses give movement in the slightest breeze: The calamagrostis sways like pennants on wires on the meadow's southern edge, and the molinia stems shimmer veil-like on its western side. From high summer into fall, the full meadow goes through subtle color gyrations.

For Carroll and Marcus and their neighbors, the garden presents layers of color and texture, and a kinetic quality augmented by the birds. Mallard ducks, doves, sparrows, goldfinches and other species find both refuge and food here. In this 10,000 square feet of meadow 42 feet in the air, they thrive unmolested by cats, raccoons, people, snakes or floods. Only landscapers have access to the plants, and they must use long ladders. "Nobody picks the flowers," said Marcus, chuckling. And yet from their fifth-floor, two-bedroom condo, it's almost as if you can reach out and stroke the grasses.

Look to the right, and the meadow forms the ground plane for a view of Key Bridge with the Rosslyn skyline behind. Look downriver, and the garden frames a vista of the Potomac curving before the Watergate and the Kennedy Center. With the balcony door open, the apartment is filled with the whooshing of cars on the Whitehurst Freeway and the growl of jets twisting their way to Reagan National Airport. Close the door, with its soundproofed glass, and the scene shifts to one of surreal silence. The calamagrostis continues to dance.

Marcus and Carroll live in the plush condo building known only by its address, 3303 Water Street. The nine-story building is sandwiched between the freeway and the C&O Canal, and contains 72 apartments. It looks like a converted factory or warehouse but is only five years old and stands on a site that used to be occupied by electrical transformers and a canalside hill.

**********************************************

The garden was planted and is maintained by Washington Landscapes, whose owner, Peter C. Dickens, lives in the condo building, though his view is of the C&O Canal. His 10-member crews spend a day on the roof each month between March and December. The gardeners gain access with long extension ladders tethered to the roof's parapet. Wearing rock-climbing gear for safety, they use ropes to move material on or off the roof. They check the irrigation system and hand-pull weeds and any little trees that the birds have brought in. All the dead top growth of the grasses and perennials is cut and removed in late winter. Maintenance is funded by the residents' condo fees.

In the spring, thousands of daffodils sway in the April breezes. By June, the herbaceous plantings provide a textured carpet of green against the rose pink drifts of Nearly Wild and the oranges and yellows of daylilies. By July, flowers erupt for a summerlong display, including the wispy violet blossoms of the Russian sage, the golden black-eyed Susans and the azure blossoms of the chaste tree. The roses just keep blooming.

When visitors see the meadow "they say you've got your own Serengeti," Marcus said. "They can't get over it."

- FLAP (Fatal Light Awareness Program) Toronto - check out their Lights out Toronto Program

- Toronto Becomes World's First City to Mandate Bird-Friendly Buildings - PRESS RELEASE: October 28, 2009

***********************

From "Amended Toronto Green Building Standards Retain Bird-Friendly Measures" (November 2009)

"Council left intact existing green standard measures aimed at preventing bird-building collisions.
Window glass on new constructions must still be treated with a density pattern of between 10 and 28 centimetres apart or otherwise be able to mute reflections for at least the first 10 to 12 metres of a building, above grade.
 
The same goes for a requirement that builders ensure ground-level ventilation grates have a porosity of less than two centimetres by two centimetres.
 
Council adjusted new reduced light pollution targets “to make them a little clearer,” Welsh said.
New constructions and properties must reduce nighttime glare and light trespass, exterior light fixtures must be shielded to prevent glare or light trespasses onto neighbouring properties, and the city no longer allows up-lighting from exterior light fixtures unless a heritage designation applies.
The City has also added one requirement. When green roofs are built adjacent to glass surfaces, the glass must be treated to at least 12 metres above roof-level.
 
“We did a study on migratory birds and that was one of the recommendations from the study,” Welsh said. "

bird skyscraper design (Chicago)

A skyscraper for the birds: Aqua gets an award from animal rights group

Chicago architect Jeanne Gang's 82-story Aqua tower (left) isn't done yet, but PETA (People for the Ethical Treatment of Animals) is giving Gang and her firm, Studio Gang Architects, an award for the bird-friendly design of Aqua. The group says that birds are less likely to kill themselves flying into Aqua's windows because of the skyscraper undulating curves and because its exterior glass is etched with marks that birds will be able to see.

"The American architect Louis Sullivan coined the phrase 'form follows function,'" PETA's president, Ingrid Newkirk, says in a news release. "In the Aqua Tower, form follows compassion."
