Vanity Fair, Vogue and Elle magazines devote glossy pages to climate change. Luxury eco-resorts beckon. Actor Leonardo DiCaprio makes a point of driving a Prius. And sustainability may finally be a reality for ordinary folk here, too, as plans to build a model eco-commu- nity at the former Canadian Forces Base Rockcliffe are set to blossom. At an open house on Wednesday, the public will get a glimpse of what it would be like to live in a more environmentally friendly way. Canada Lands Company, the Crown corporation in charge of the project, will unveil its community design plan for the vast area to be developed during the next 12 years. Spread over 135 hectares (320 acres), the area will likely be the largest eco-communi- ty in Canada. The proposal shows eight distinct neigh- bourhoods made up of stores, offices and 4,500 to 6,000 houses and apartments. It al- so identifies roads and natural areas (see map, right). Ten acres will be set aside for a national museum or a federal institution. Construction is to start in late 2008, with the first residents moving in in 2009. But what does it actually mean to live green? It means designing streets and buildings as though you believe global warming, cli- mate change and oil shortages are for real. In an urban sustainable community, buildings are close together and streets are designed so people can walk easily or cycle instead of driving everywhere. Good public transit is essential. Buildings are designed for maximum energy efficien- cy. Alternative energy systems lend a hand. Recycling and composting gets serious. “We want to do as much as we can to re- duce the actual number of trips in a car,” says Ed Lowans, the project’s Ottawa-based sustainability consultant. “It’s relatively easy to make changes in buildings. Getting people not to use their cars as much is a more difficult challenge. “This is the nation’s capital,” says Mr. Lowans. “We want to demonstrate to peo- ple who visit Ottawa in an official capacity that we can show significant leadership in creating a sustainable community. It’s something that Canada is trying to export. “What the consumer is getting out of it is a lower energy bill, a lower water bill and much nicer biological surroundings,” says Mr. Lowans. “The overall vision is built on the existing ecology and topography of the site because it’s exceptionally rich. It has fabulous views. It has nice flowing topography, a couple of little cliffs and a natural water course. These are the kinds of things that people look for in an ideal setting.“ The plan aims to protect the escarpment, the existing landscape and create green corridors that link the Montfort Woods and the National Capital Commission lands to- ward the Ottawa River, adds Ottawa archi- tect Barry Padolsky, who is in charge of public consultation. Mr. Lowans, who suffers from environ- mental hypersensitivity, hopes to create a less-allergenic environment for people with allergies, asthma and environmental sensitivity. “If we can change the way that we do landscaping in the urban environment, we can have a major impact on the health of the population,” he says. He points out that during the past 50 years there has been a trend toward select- ing male trees that didn’t produce messy nuts or seeds. But they do produce pollen, a culprit in seasonal allergy miseries. “We’d like to use trees and bushes that don’t generate pollen,” says Mr. Lowans, adding that they expect to grow replace- ment trees in an organic, pesticide-free nursery in the community. Canada Lands and its consultants have given the Citizen an inside look at some of the eco-friendly thinking that will shape the massive Rockcliffe redevelopment. What makes Rockcliffe special are the number of sustainability measures and its large size. “Most demonstrations have one or two technologies at a time,” says Mr. Lowans. “We will look at hundreds of innovations. We’re trying to demonstrate this can be done on a wide scale.” The Rockcliffe team have yet to establish targets, but, for example, they hope to make buildings at least 25-per-cent more energy efficient than required by the Ontario building code. Houses built in this way may cost “any- where from a few thousand dollars more to $10,000,” Mr. Lowans says. “But you’ve got significantly reduced en- ergy bills. The payback is within three or four years.” Neighbours of the airbase are expected to participate. The National Research Council, the Canada Mortgage and Housing Corpora- tion, Natural Resources Canada and the Canadian Centre for Housing Technology are all involved in sustainability and ener- gy-efficiency research that could be ap- plied — and demonstrated — in the houses and commercial buildings at Rockcliffe. Rockcliffe: An eco-town starts to take shape As planners unveil their plan for the site of the former air base this week, MARIA COOK looks at what it will take to make it green Imagining a new Rockcliffe Planners are proposing eight different neighbourhoods to be built on the former air base. Photos from other cities show the character of buildings and streetscapes they envision Centretown The town centre would include a “high street” with shops, offices, public transit and a market square. There will be apartments and offices above shops as well as residential buildings looking out over a network of linear parks. Montreal Road Gateway Currently vacant lands owned by National Research Council would be developed as a mixed-use area fronting onto Montreal Road. It would include offices, retail stores and a mix of low to mid-rise apartment buildings. Public transit would enter the site through here. North,South and West villages Located at the west end of site, these areas are currently occupied by military housing, which could be renovated and updated. It is potentially a mixed-use area, but not one of high density. Forest Houses The northeast corner of the site, currently occupied by the former residences of officers, could be redeveloped as a showcase for custom designed houses within a treed landscape. Research City Connected to Centretown on the east side by a main street, this area is beside the current National Research Council campus. It would be a mixed-use district of housing, office and retail with an emphasis on employment related to research. Hill Town Located on top of the escarpment, this is a sloped area that overlooks the Ottawa River. It would be mostly residential, likely a mix of single-family houses, rowhouses and apartments. See ROCKCLIFFE on PAGE A8 Hammarby Sjöstad is a waterfront devel- opment built on a decontaminated industri- al site in the centre of Stockholm, spread over 200 hectares — about half the size of Ottawa’s Central Experimental Farm. Gleaming five-storey apartment build- ings are designed to maximize access to sunlight and views of the surrounding lake. The neighbourhood’s parks, canals, water- front walks and handsomely paved streets help to make it one of Stockholm’s most de- sirable areas. The project is half finished, with about 13,000 residents, 200 companies, a school, a library and church. When completed in 2015, Hammarby Sjöstad will have 9,500 apartments and 2.7 million square feet of commercial space. Altogether, 35,000 peo- ple are expected to live and work in the area. Thousands of foreign visitors come to learn from Hammarby Sjöstad. One thing they learn is that people don’t really want to live differently — even in an eco-town. “People don’t move here to live in a sus- tainable city area,” says Ms. Wangel. “They move here because it’s close to the city, it’s close to nature and it’s a newly built area with nice architecture. So far, we haven’t managed to get inhabitants to change their behaviour to more environmental ways of life.” It’s an important lesson for the develop- ers of the former Rockcliffe air base, which will also attract residents who want to be in a beautiful natural setting close to down- town. Hammarby Sjöstad was originally intend- ed to be the Olympic village in Stockholm’s bid for the 2004 Summer Olympics. When the International Olympic Committee chose Athens instead, Stockholm planners set about to create a mixed-use neighbour- hood, keeping the high goals for environ- mental performance — “twice as good as the norm.” Or, as Ms. Wangel puts it, “to be half as bad.” The focus was to be on renewable energy, waste reduction, ecological building mate- rials, and alternative transportation op- tions. At first, the planners had imagined a car-free area. Politicians nixed that. When it came time to build residential parking garages, the city wanted no more than three spots per 10 units. That’s when people went ballistic. Not everyone seemed clear on the con- cept. For instance, when Stockholm’s condo market softened, one developer offered a free car with every apartment at Hammar- by Sjöstad. “The city tried to say this is supposed to be a sustainable city, you don’t have to use your car, but somehow the ownership of a car is so deep buried inside the Swedish soul. People really want to keep their car. So the politicians have removed this goal from the environmental program.” The current ratio is about eight spots per 10 units. About 66 per cent of households own a car, which is similar to the average for the inner city. Still, they use them less than in other areas. A 2005 survey found that two-thirds of all trips are made by pub- lic transport, bicycle or walking and a third of trips are by car. The alternatives include a new light rail tram, two local buses, a ferry and pedestri- an bridges. Two big shopping malls are reachable in 15 minutes by bike. You can walk to a supermarket in 15 minutes. One in eight families belong to the car pool. These cars, mostly hybrids or biogas, are available with the swipe of a smart card and eligible for the best parking spots in town. As Kermit the Frog sang, “It’s Not Easy Bein’ Green.” That means developers must make it easier for people. “It’s very important to install public tran- sit at the same time as building the new area because you want to install new travel habits,” says Hans Lundberg, professor at the Swedish Environmental Research Insti- tute. For the developers of the former Rock- cliffe air base it underscores the need for excellent transit from the beginning, as well as schools, parks, preschools, recreation centres and stores. Ms. Wangel notes that two of the biggest demographic groups in the area are seniors who have downsized and young families. The city has been praised for taking steps to attract shops and services to the area in the early phases of development by offering Stockholm: A neighbourhood where it’s easier being green Like many of us, Swedes don’t want to give up driving or live differently — even in this new environmentally sustainable development. But here, it’s no extra effort to leave the car behind, save energy or sort the garbage two years rent-free. The city also reserved ground floors of buildings on main streets for business. Ms. Wangel’s advice to anyone hoping to create a sustainable area is to set up an in- formation centre from Day 1. One is planned for Rockcliffe. “This info centre opened in late 2002, and by then people had been moving in at least two years,” she says. “It’s very important the minute they settle that they get information about the sustain- ability concept of the area.” Many residents still do not make even small changes such as avoiding running wa- ter when doing the dishes, changing to low energy light bulbs or turning out lights when they leave home, she says. “People are quite lazy. They don’t want to change their behaviour if they don’t have to.” However, because of the innovative waste system in the area, they must do some things differently, such as sorting waste for recycling. “They’re sorting waste better here than in similar areas in Stockholm, but not as good as they could,” says Ms. Wangel. In Hammarby Sjöstad, about 65 per cent of the apartments are purchased and 35 per cent are rental. It costs about four-per-cent more to build in an environmentally friend- ly way than conventionally, says Ms. Wan- gel, but in the longer term owners and oper- ators save money on energy bills Property values here are about the same as newly built housing in similar areas of Stockholm, says Ms. Wangel. The Commission for Architecture and the Built Environment, the British govern- ment’s adviser on architecture and public space, recently evaluated Hammarby Sjös- tad and found that accessibility to public transit was a key to the district’s success. The light rail tram “has proved to be an es- sential public sector investment in infra- structure, which has acted to stimulate the market for residential development in the area,” says the commission’s report. “The particular lesson from the Hammar- by Sjöstad case study is the powerful role that strong public sector leadership can play in ensuring development of the high- est quality,” it added. Residents seem to agree. A survey last year found that residents were generally “very satisfied” with the environment at Hammarby Sjöstad. Open house this week When: Wednesday.

Sustainability is finally sexy.Vanity Fair, Vogue and Ellemagazines devote glossypages to climate change.Luxury eco-resorts beckon.

Actor Leonardo DiCaprio makes apoint of driving a Prius.

And sustainability may finally be areality for ordinary folk here, too, asplans to build a model eco-commu-nity at the former Canadian ForcesBase Rockcliffe are set to blossom.

Canada Lands expects to demonstratenewer technologies that are currently toocostly for mass use, and incorporate themin later phases as they become affordable.These includes light-emitting diode(LED) lights for streets and buildings andsolar collectors that work in northern cli-mates to generate both electricity and hotwater.

Canada Lands’s Benny Farm project inMontreal proved environmentally friend-ly housing could be built affordably. ButRockcliffe is a bigger and more compli-cated project.

The crunch will come when it’s time tosell land — Canada Lands will eventuallysell parcels of the site to developers whowill be expected to build their vision.

“Canada Lands is governed in such away that they have to get the highest val-ue and that’s all that counts,” saysJonathan Westeinde, managing partner of

Ottawa-based Windmill DevelopmentGroup. “Their own measurement toolsfor achievement are going to hinder themfrom getting what they want.”

Will Canada Lands be required to ac-cept the highest bid, but with a compro-mised product such as taller buildings,less public space or fewer energy fea-tures? Or will Rockcliffe truly become amodel for 21st-century living?

Jim Lynes, Canada Lands acting presi-dent and CEO, has said that at Rockcliffethey hoped to pursue the best proposals,not necessarily the highest price offeredby developers for the land parcels.

“I think we’ll be much better placed inthis particular development of goingthrough a process that will identify keypeople who actually have the skill set andshare the vision of what we are trying toachieve,” he said.

“We want to find a mechanism otherthan a competitive highest bid to set a fairvalue.”

Rockcliffe: Will the bottom linecompromise the lofty aims?

TRANSPORTATION■ Light rail has been considered a keyelement, either coming into the area orpassing along its edge along Montreal Road.This is in jeopardy as Ottawa’s mayor-electLarry O’Brien has said he wants to rethink thelight-rail plan and will seek a six-month delay.■ Car alternatives include bike paths, carpools, a shuttle to the Transitway and payingOC Transpo to provide a higher level ofservice. Canada Lands expects to market thearea to people who are interested in lessreliance on a car or people who can’t affordone — 25 per cent of the housing is to beaffordable.■ Narrower roads use less asphalt and thusallow more green space, which has a coolingeffect in summer and reduces the need for airconditioning. The obstacle will be to convincethe city, which favours wider roads for theease of fire trucks and snow plows. The city issetting up a committee of people from

various departments to work with CanadaLands on such issues. Could the city rethinkthe size of vehicles? Fire trucks have beengetting bigger, and the city clears snow onresidential streets using the same plows ason collector roads.

WATER■ Reduce usage: Use 50-per-cent lesswater than a conventional building using suchdevices as low-flow toilets and showerheads.■ Collect rainwater: Use to flush toilets,irrigate gardens and wash cars.■ Reduce stormwater runoff: Excesscould flow into a stormwater retentionsystem that includes ornamental wetlandsand ponds. Shallow ditches between roadswould allow the water to infiltrate soil. “We want to have little or no stormwaterleaving the site,” says sustainabilityconsultant Ed Lowans.

ENERGY-EFFICIENT BUILDINGS■ Renewable or recyclable materials:Such as wood from crop trees rather than oldgrowth. Use materials produced in region,which would draw on less energy to get to thesite. Use any trees cut on site for lumber.■ Solar energy: Orient buildings accordingto sunrise and sunset to take advantage ofpassive solar energy and shade.

■ Solar roof panels: Boost theeffectiveness of high-efficiency furnaces andgood wall insulation.■ Green roofs: Use to cool buildings insummer and retain heat in winter.

AIR QUALITY■ Indoors: Choose materials that don’t giveoff gases, such as wood floors or ceramic tilerather than carpet. Reduce emissions fromsuch building materials as paints, plastics and plywood. Improve ventilation systems,reduce the use of pesticides and begininformation campaigns to discourage use of perfume, bug spray and chemical cleaners.■ Outdoor: Plant female tree and plantspecies, which do not generate pollen.

GARBAGE ■ Compost from grass clippings, woodchips, food waste from restaurants andkitchen waste from houses could be used foron-site greenhouse, fish farm and treenursery.

SMART METERS■ Measure energy efficiency. Technologycould control the amount of energy usedduring peak periods, such as heat waves andcold snaps.

Green goals for RockcliffeSome of the ideas being considered for the Rockcliffe sitethat would make it more environmentally sustainable:

7. A VACUUM SYSTEM FOR GARBAGE ANDRECYCLINGThere are no garbage trucksroaring up and down streets,smelly dumpsters or piles of garbage at the curb. Instead, residents put theirgarbage, paper, plastic,cardboard, glass and foodwaste in 11 different bins.Each is sucked away tounderground storagechambers (far right). On collection days, wastedisposal vehicles suck outthe contents of thechambers. The material isreturned as biofuels,electricity and heat.

COVER STORY

8. CAR ALTERNATIVESNew light rail tram, buses,biogas-operated ferry, carpools, beautiful footpathsand cycle paths were built.The city also created anunderground motorway toserve the area.

9. VEGETATIONThe footpaths, preserved oakforest, parks and newlyplanted trees help to collectrain water, ensure cleaner airand provide counterbalance to the dense urban landscape.
