Design like you give a damn

A simple mission: “to generate design opportunities that will improve living standards for all” by providing an open-source platform through which ANYone can view, post, share, and adapt sustainable, humanitarian-based, scalable solutions. The idea that designs and all associated documents can and should be shared within the decidedly proprietary architectural industry is truly innovative, and could very well aid in the reshaping of the entire architectural profession into a more socially-focused and responsible vocation.

Kinetic walking sculptures

August 29, 2008 · 1 Comment

Theo Jansen´s kinetic sculptures are alive!

walking bugs

“Theo Jansen has been creating wind-walking examples of artificial life since 1990. What was at first a rudimentary breed has slowly evolved into a generation of machines that are able to react to their environment: “over time, these skeletons have become increasingly better at surviving the elements such as storms and water and eventually I want to put these animals out in herds on the beaches, so they will live their own lives.” From >Inhabitat

These sculptural ‘animals’ are amazing; like a combination of DaVinci and David Cronenberg. Jansen has hit upon a form that resonates with a sense of the future/past as present; fairy tales, dinosaurs and mythical beasts.

Inflatable plastic bag subway art

August 5, 2008 · 1 Comment

Artist Joshua Allen Harris´ plastic bag polar bear

Polar bears, polar bears. Those ubiquitous symbols of climate change. Cute and cuddly, ethereal and majestic, they’re popping up everywhere - including atop subway grates on the streets of New York City. Artist Joshua Allen Harris has created quite an online buzz with his puppy-like inflatable plastic bag polar bear: it inflates and deflates with the passing of subterranean subway trains, springing to life and then fading away in a vital commentary on global warming.

Announcement: Ekosähkö Oy

July 30, 2008 · No Comments

Ekosähkö

An announcement, better late than ever:

Aito, and most of its affiliates, has tossed Helsingin Energia into the trash bin (except for the monopolized transfer part) and has a new electricity provider: Ekosähkö Oy http://www.taustavoimaa.fi/ekosahko/.

Ekosähkö produces electricity through small power plants and at least one third third is produced by wind power. We made the contract here (keep the suggested parameters unchanged, consumption of energy for an one-two person household is 2000 kWh/year) http://www.taustavoimaa.fi/ekosahko/laskuri/ekosahko/index.asp

We will see in some time how it works. :)

Electricity through my window

MIT opens new ‘window’ on solar energy

Cost effective devices expected on market soon

Imagine windows that not only provide a clear view and illuminate rooms, but also use sunlight to efficiently help power the building they are part of. MIT engineers report a new approach to harnessing the sun’s energy that could allow just that.

The work, to be reported in the July 11 issue of Science, involves the creation of a novel “solar concentrator.” “Light is collected over a large area [like a window] and gathered, or concentrated, at the edges,” explains Marc A. Baldo, leader of the work and the Esther and Harold E. Edgerton Career Development Associate Professor of Electrical Engineering.

As a result, rather than covering a roof with expensive solar cells (the semiconductor devices that transform sunlight into electricity), the cells only need to be around the edges of a flat glass panel. In addition, the focused light increases the electrical power obtained from each solar cell “by a factor of over 40,” Baldo says.

Because the system is simple to manufacture, the team believes that it could be implemented within three years–even added onto existing solar-panel systems to increase their efficiency by 50 percent for minimal additional cost. That, in turn, would substantially reduce the cost of solar electricity.

The Walkability map

June 29, 2008 · 1 Comment

City Walkability map

WalkScore is developing colour coded walkability maps for cities. This is a great tool when buying an apartment, for tourists choosing hotels and for city and traffic planning. The basic score for Helsinki centre walkability is 74 out of maximum score 100 (Helsinki walkability). Hopefully we will soon have a full colour coded walkability map of Helsinki, too! //aito

The Seattle city walkability map

What makes a neighborhood walkable?

Walkable communities tend to have the following characteristics:

  • A center: Walkable neighborhoods have a discernable center, whether it’s a shopping district, a main street, or a public space.
  • Density: The neighborhood is dense enough for local businesses to flourish and for public transportation to be cost effective.
  • Mixed income, mixed use: Housing is provided for everyone who works in the neighborhood: young and old, singles and families, rich and poor. Businesses and residences are located near each other.
  • Parks and public space: There are plenty of public places to gather and play.
  • Accessibility: The neighborhood is accessible to everyone and has wheelchair access, plenty of benches with shade, sidewalks on all streets, etc.
  • Well connected, speed controlled streets: Streets form a connected grid that improves traffic by providing many routes to any destination. Streets are narrow to control speed, and shaded by trees to protect pedestrians.
  • Pedestrian-centric design: Buildings are placed close to the street to cater to foot traffic, with parking lots relegated to the back.
  • Close schools and workplaces: Schools and workplaces are close enough that most residents can walk from their homes.

Your Walk Score is a number between 0 and 100. Here are general guidelines for interpreting your score:

  • 90 - 100 = Walkers’ Paradise: Most errands can be accomplished on foot and many people get by without owning a car.
  • 70 - 90 = Very Walkable: It’s possible to get by without owning a car.
  • 50 - 70 = Some Walkable Locations: Some stores and amenities are within walking distance, but many everyday trips still require a bike, public transportation, or car.
  • 25 - 50 = Not Walkable: Only a few destinations are within easy walking range. For most errands, driving or public transportation is a must.
  • 0 - 25 = Driving Only: Virtually no neighborhood destinations within walking range. You can walk from your house to your car!

The Bankside Urban Forest

March 2, 2008 · 2 Comments

Questioning common design on “safe” neighbourhoods

The regeneration of London’s Bankside quarter, most famous for the Tate Modern, is being accompanied by a public space strategy with an ecological approach.The Bankside Urban Forest is a proposal for a wholly new concept of urban green space networks and linkages.

This scheme for the London Bankside urban renewal has grown out of a strong sense that local residents perceive the area described in the scheme as being “calm”,“safe”, and enjoying a strong sense of local identity already. It is not the case, however, that labyrinthine means dangerous, as local residents confirm. Conventional public space strategies are often informed by safety concerns which suggest that large open spaces and long straight vistas must invariably feel safer. Yet many people find large, hard-surfaced landscapes threatening by their sheer lack of incident and anonymity. Local residents around Bankside find no contradiction between describing the area as feeling safe, along with praising the irregular network of streets and back doubles. What they do fear, however, is the “Manhattanisation” of Bankside north of Southwark Street, and the forest concept is one which it is intended will weave human scale and engaging pathways and networks linking old and new Bankside together. Local residents interviewed for this study have confirmed the importance to them of the distinctive irregular street patterns of the area, together with the many courtyards, railway arches, viaducts, bridges and alleyways. Thus, there were great strengths in respecting the existing labyrinthine set of streets and settlements, which inspired the idea of the Bankside forest.

Bankside Urban Forest plan Bankside is a densely populated and historic quarter on the southern bank of the River Thames in London.The area is being regenerated, with about 50 projects currently under consideration. Several illustrative projects (dark green) have been proposed to help bind the public space network together.

This proposal imagines the Bankside public realm strategy as an urban forest rather than a park. There is an important difference. The term park originates with the Latin parricus or French parc, both meaning enclosure. The early English deer-parks were royal hunting grounds and strictly policed, for instance, whereas the forest has always been regarded as a place of liberty and without distinct boundaries.
Over time, “forest space” has acquired a set of architectural and topographical associations with a sense of open-endedness and permeability, a place that can be entered or exited at any point at its edges, and which visually changes and re-configures itself as the traveller moves through it. Because of their organic origins, forests offer a multiplicity of paths, routes, changes of direction, as well as clearings, copses, streams, rides and allées. “A person should be able to walk through a forest on the way from home to work,” the architect Alvar Aalto once said.

“If forests appear in our religions as places of profanity, they also appear as sacred. If they have typically been considered places of lawlessness, they have also provided havens for those who took up the cause of justice and fought the law’s corruption. If they evoke associations of danger and abandon in our minds, they also evoke scenes of enchantment. In other words, in the religions,mythologies an literatures of the West, the forest appears as a place where the logic of distinction goes astray.”

Thus, there were great strengths in respecting the existing labyrinthine set of streets and settlements, which inspired the idea of the Bankside forest.

Though the forest idea introduces elements now associated with “greening the city”, and largely determined by ecological imperatives – to counter CO2 emissions, to lower ambient temperatures, to increase surface water retention and avoid flooding – there are equally important social and economic imperatives in the forest strategy too.

Bankside Urban Forest perspective trunks

The intensification of existing public spaces allows for a hybrid of new urban forms. In Flat Iron Square, the existing café could be turned into a woodland hut built around the trunks of the mature plane trees.

In addition to strengthening the historical jigsaw of spaces and places, the forest concept also introduces a slowing down of time, based on the experience of irregular pathways and frequent and engaging visual incident. Urbanists have for some time now been drawing attention to the “overscripting”of public space in many urban regeneration schemes, so that all conflicts and loose ends are designed out, and the public are organised into patterns of use and timetables decided elsewhere. This disallows for that sense of wandering and of discovering a neighbourhood by serendipity. The very qualities for which we admire historic European towns and cities.

Energy from waste and the bottom of the sea

February 26, 2008 · No Comments

Vaasa Housing Exhibition runs on waste

The houses at the Housing Exhibition 2008 in Vaasa will be heated by energy from the old abandoned waste dump and by energy from the bottom of the sea.

-”We realized that the temperature of the sea bottom a few metres deep will remain at +8-9 degrees celsius even in the coldest winter. Up on land at the same depth the temperature is only +3-4 degrees. “, one of the two innovators of the idea tells. “Even the experts were surprised”.

The housing exhibition area has its own energy station that transforms and moves out the energy into the city´s energy network. The methane gas taken to use from the old waste dump in Suvilahti will last for twenty years, but the sea is a huge energy reservoir. “There is potential for the future”, Mauri Lieskoski says.//aito

Sunnanvik

Från den nedlagda sopstationen i Sunnanvik transporteras metangas till en nybyggd energianläggning. Enheten, utrustad med bränslecell och mikroturbiner, producerar el och värme som sedan körs ut i Vasa Elektriskas nät. Totalt får över 40 småhus och tre höghus sin el- och värmeenergi via mässans kraftverk.
Juvelen i kronan är det lågtemperaturnät som suger upp jordvärme från ett 40 meter tjockt sedimentlager på havsbottnen. Nästan åtta kilometer rör är begravda under vattenytan i Stadsfjärden.
– Nätet ska vara i bruk året runt. På somrarna används det till att kyla ner husen, säger Mauri Lieskoski på företaget Mateve.
Det var Vasaborna Lieskoski och Pertti Reinikainen som gjorde den sensationella upptäckten. Deras mätningar visade att medeltemperaturen i jordlagret är 8–9 grader på 3–4 meters djup – vintertid. Uppe på landbacken, i torr mark, är motsvarande temperatur 3–4 grader.
– Haven och insjöarna är stora solpaneler. Det handlar om enorma energikällor och värmeförråd, säger Lieskoski.
– Den största utmaningen består i att fördela värmen på ett jämnt sätt. Det fungerar bra på ett avgränsat område men vi vet inte hur långt man kan transportera havsvärmen. Det krävs mera forskning.
Fyndet överraskade energispecialisten Jarmo Kallio på Geologiska forskningscentralen.
– Bottensedimentet lagrar solvärme effektivt under sommaren. Tack vare vattenmassorna avkyls det inte ens under kalla perioder. Här finns stor potential.
Framtidens teknik
Bränslecellen har utvecklats av Wärtsilä. Kraftverket är det första i sitt slag som drivs med gas från en avstjälpningsplats. Mikroturbinerna och bränslecellen producerar en energimängd som motsvarar den årliga förbrukningen för 150 egnahem.
– Enheten tillverkar miljövänlig el- och värmeenergi med mycket hög verkningsgrad. Utsläppen ligger på en ultralåg nivå. Om några år kan man börja använda tekniken kommersiellt i hotell och butiker. Vi kommer till exempel att testa bränsleceller i fartygsmotorer, säger Juha Kytölä, vd på Wärtsilä Finland.
Sopstationen är ingen evig gasleverantör. Enligt Kytönen räcker metangasen i minst tjugo år, kanske längre.
– Fördelarna med decentraliserad energiproduktion är att kraftverken kan utnyttja lokala energikällor effektivare. Dessutom blir bränsletransporterna kortare.
Stort intresse
Enligt Henrik Vehkaoja är lågtemperaturnätet en relativt billig affär för husbyggarna.
– Investeringskostnaderna är höga, men driften är billig. Intresset har varit stort. Merparten av husen kommer att vara anslutna till nätet.
Anslutningsavgiften för ett egnahem är 1 500 euro plus moms. Energiförbrukningen mäts inte men hushållen betalar en bruksrättsavgift på 2,50 euro plus moms per uppvärmd kvadratmeter och år.
Satsningen i Vasa har väckt uppmärksamhet också utomlands. I den senaste upplagan av State of the World, som ges ut av Worldwatch-institutet, används Vasaprojektet som exempel på att det går att producera energi ur biogas från avstjälpningsplatsen.

– Projektet kan tjäna som föredöme för hela energisektorn. Det här är hållbar utveckling och ekologiskt boende, säger projektchef Keijo Ullakko.

La tour vivante - the vertical farm

Grow your own food!

Would you have ever thought it conceivable to grow vast amounts of produce in the heart of densely populated cities ?

The concept of eco-tower “Tour Vivante” aim is to associate agricultural hydroponic production, dwelling and activities in a single and vertical system.

A continuous agriculture, emancipated from seasons and climatic hazards (drought, flood, weather), which provides a production 5 to 6 time better than open fields cultures.

Tour Vivante allows a local production and to wipe out transportation needed for food supply and thus, the process of the very energy-consuming preservation.

The hydroponic agricultural production purifies the districts air by the provision of plants oxygen.
An efficient use of salvaged rainwater is transformed into drinking water by the evaporation/respiration of plants.
Tour Vivante generates a large amount of methane or electricity by the fermentation of food waste and vegetals.

Located at the top of the tower, two large windmill directed towards the dominant winds produce electricity facilitated by the height of the tower. The produced electric power is about 200 to 600 kWh per annum.

4 500 m of photovoltaic panels included into the facades generate electricity from solar energy.

This tower will have as well : Rainwater and Black water systems, Ecological or recycled materials and Thermal and hygrometrical regulation.

Vertical farming could revolutionize the way we produce food. This new model could replace, traditional farming methods. This is one idea where the sky is truly the limit.

Guerilla gardening

February 7, 2008 · No Comments

Urban gardening

Regardless of whether you are an urban, suburban, or rural dweller, there is inevitably a patch of neglected turf in your neighborhood that might need a bit of TLC and greening. If you see hidden gardening potential between sidewalk cracks when others see decay and abandon, well then, you might be a budding guerrilla gardener and not even know it! The guerrila gardening phenomenon is currently sweeping the globe as folks are finding innovative ways to come together for the optimization of neglected land and paved surface area. It’s a turf war for some, or a poetic gesture for others, but either way, citizens are rolling up there sleeves to create gardens in the most unlikely spaces and places.

The term ‘guerrilla gardening‘ might scare off some, but the practice has a long history of both radical and community-building tactics. Liz Christy and the Green Guerrillas transformed an abandoned lot in NYC’s Bowery during the 1970’s and as the BBC recently reported, guerrilla gardeners are ’sowing the seeds of resistance’ in South London. Many ‘resistance gardeners’ consider themselves to be vandals of sorts but with plants or seeds as weapons, often operating covertly at night in empty lots or on public property that otherwise remains unkept or barren.

The Guerilla Gardening website has a friendly though subversive sort of tone, as it has gone from tracking the activities of “illicit cultivation around London” to being a “growing arsenal for anyone who is interested in waging war against the neglect of public space.” It’s troop digs are warm and inviting and ultimately about reclamation, beautification, and even growing food in public spaces (a political act in and of itself as we re-educate ourselves about viable land use). The lighter side of the guerilla gardening campaign would probably be community gardens or grassroots gardening, which also brings folks together (during daylight hours) for neighborhood improvement and local food security. Whether as collective green graffiti or as an attempt to reclaim the neighborhood and make improvements for all, guerrilla gardening is a form of eco-activism that is catching on despite its controversial methods.
