Jätkäsaari will also have a city block with low2no sustainable construction, which has ambitious energy-efficiency goals. the aim is to make the block a national model of carbonneutral construction. let's be close! The Jätkäsaari energy and eco-efficiency goals are ambitious. The first eco-solution lies in the density of the urban structure. "We are building a neighbourhood, not a suburb. The compact design creates synergy benefits and reduces the need for transportation and investments. This saves energy and natural resources," notes Matti Kaijansinkko, architect and project leader in charge of the Jätkäsaari design. Jätkäsaari is a peninsula. The city blocks are designed to protect the courtyards of the buildings from the icy marine winds. The possibilities afforded by the latest technology are integrated in the construction of the buildings and the infrastructure. For one, garbage trucks are a thing of the past: Waste from the area is transported to a central waste collection point via an underground vacuum system. getting from the cruise ships docked on the south side of Jätkäsaari to downtown Helsinki. "The design of the area has been approached from a mobility management perspective," Kaijansinkko notes. There are few streets for driving and the residential streets are cul-de-sacs. Through traffic is virtually non-existent. Parking for cars is primarily underground. Each block has two parking spots reserved for cars belonging to car-share clubs. Eco-cities to China hina is facing an unprecedented challenge in the history of the world as some 400 million people from rural areas relocate to cities over the next 15 years. Numerous new cities will be built in China, cities that either consume a fraction of the energy consumed by existing cities or even produce more energy than they use. The Finnish company DigiEcoCity Ltd signed an agreement in spring 2009 regarding the construction of two ecological model cities in China, each with about 100,000 residents: one in Gongqing, Jiangxi Province, and the other in Danyang, Jiangsu Province. "Climate change, urbanisation challenges, and the necessity for construction that is more eco-friendly than before have been a key focus in the ministeriallevel negotiations between Finns and the Chinese," says Mauri tommila, president of DigiEcoCity. A Finnish-Chinese joint venture is responsible for construction, and a number of Finland's leading high-tech companies are participating in the project. The cities are expected to be completed within five years or so. "Eco-solutions integrate all the aspects of sustainable lifestyles. The need to travel is reduced, energy is produced with a suitable combination of renewable sources, energy waste is minimised, water management, recycling and waste management are efficient. The challenges are enormous, but the future solutions can be implemented with minor compromises in China," Tommila notes. Z C let's build sustainably! Eco-efficiency is a hallmark of the massive fifteen-year construction project. The area's contaminated soil from decades of port operations is not being transported away. It is being buried under the planned park area and segregated so that it doesn't pose a threat to the people using the park. The old, colossal warehouse building is being converted into a fitness centre. "The challenge is to make the area so enjoyable that the residents won't necessarily want to travel anywhere else on their days off work. The park will feature a sledding hill for kids; and a sandy beach for those hot summer days will be built in the sheltered cove," Kaijansinkko describes. Z let's ride the tram! In Jätkäsaari, everything is easily accessible on foot. A five-minute bike ride via the connecting boulevard will put you in downtown Helsinki. Shops and services will be decentralised. Good ol' tram service will provide public transportation in the area as well as a convenient way of Low2no Sitra and its partners are designing a sustainable construction block in Jätkäsaari. Ideas and solutions for energy-efficient and sustainable construction were pursued through the international Low2No competition. A total of 75 teams from 23 countries expressed an interest in entering the competition. Five were invited to participate. The winner of the competition was the team comprised of Arup (England), Sauerbruch-Hutton (Germany), Experienti (Italy) and Galley EcoCapital (USA). 31
