Public design that cools the heat of the city
Green Roof
The Earth is getting hotter and hotter due to global warming. In particular, cities are deepening every time the desolate buildings increase. As the green forest decreases, unpolluted clean air becomes scarce and carbon in the atmosphere becomes more fuller. Every summer, the temperature rises, causing hot air to exhaust the whole body. The heat island effect in the city has now reached a level that threatens the health of urbanites. What alternatives are there?
Developed countries around the world are showing various efforts to solve this problem. The most notable of them is the effort to solve this problem through urban gardens. In particular, when building new buildings, green roof designs are actively introduced using rooftop or the side of the building. The green roof is a method of decorating the exterior of the building with plants such as trees and forest flowers. This green roof design maximizes energy efficiency by reflecting light and increasing the insulation effect. This can reduce cooling and heating costs by up to 60%. It also absorbs carbon dioxide from the atmosphere and produces fresh air, making the surroundings more comfortable. Above all, it cools the heat of the city that is getting hotter and hotter. It also provides a new haven for birds that are losing their place to live due to the increasing number of cities. It is an essential public design method in the era of global warming.
Stairway green roof - Across Fukuoka Building
Across Building with impressive green space that overturned the entire building
At first glance, there is a building like a ridge. The main character is the "Across Building," a complex cultural and artistic center located in Fukuoka, Japan. The green area that overturned the entire building gives an impressive feeling. It is a building that actively has accepted the green roof method. They say that the reason for creating such a natural green space is to create an affluent and pleasant environment in the city by integrating it with the adjacent Tenjin Chuo Park. The green area is 5,400㎡, the largest among Japanese rooftop facilities. There are 76 species and 37,000 species in total. After that, the number of tree species increased due to additional planting or tree seeds carried by birds, and now it is said to be about 120 species and 50,000 trees. Anyone can use this step garden freely. In particular, the 60-meter-high terraced garden is also Fukuoka's proud attraction. The Across Building holds various art performances every week, including musicals and concerts. The combination of such artistic sensibility and green space shows a new alternative to urban ecological and cultural space.

Arlington County, Virginia, USA, is one of the most active green roof policies in the world. Various types of green roofs are concentrated here, ranging from major buildings and government houses. Arlington County is focusing on improving the energy efficiency of the entire building by introducing the LEED (Energy Environment Design Leadership) eco-friendly evaluation system of the U.S. Green Building Committee. It is also running the Green Home Choice Program to further increase the green roof. The Green Home Choice Program is a program that partially supports installation and maintenance costs for each household installing a green roof. As a result, more companies and families install green roofs every year. The cooperation between the residents and local governments is making the village more comfortable.

Ecological Park on the Building - Chicago City Hall
This is not the only eco-friendly policy of Chicago City Hall. Under the catchphrase "Green Chicago," more than 80,000 trees are planned to be planted in the city every year. In addition, along with the green roof policy, it is actively promoting five eco-friendly projects: zero waste, reduction of industrial waste, generation of natural energy, and reduction of traffic pollution. As a result, it aims to reduce greenhouse gases in cities to 25% by 2020. In addition to the policy level, the rooftop park serves as a shelter for city hall employees. Employees can get out of the stuffy office and come up to the rooftop at any time to get peace of mind under the green park. As the city's policy became widely known, visitors to the city hall also recognized the rooftop park as a must-visit course. It has become another local attraction.

Ecological Park Recycled Railroads - The High Line Park
The High Line Park, Ecological Park Recycling Abandoned Railroad Roads
Anyone who has visited Manhattan, New York, may have visited this place at least once. It is THE HIGH LINE PARK, an ecological park that recycles abandoned railroad tracks. This place was an important means of transportation for industrial goods in New York through buildings from the 1930s to the 1970s. However, advances in modern transportation technology eventually led to the closure of railroad tracks. As a result, this place has long been hideously neglected in the city. The railroad tracks that had been neglected were disappearing into history. However, the situation reversed as citizens stepped up to save this place, where New York's history was intact. With the idea of a citizen, a project to create an ecological park here began. Experts from various fields gathered to decorate the railroad tracks and plant forests and trees to create outdoor gardens. There is also enough space for people to rest.
When a green area was created here, people gathered, and now people are crowded with picnics at Highline Park on holidays. There are many people who come out to enjoy quiet contemplation as well as family and couples. The park, which runs a total of 1.6km, has beautiful scenery and a fragrant smell of flowers with various plants and flowers. Wooden tables installed everywhere are perfect for those who want to enjoy warm sunbathing. In addition, new houses are installed in the middle to provide warm havens not only for people but also for birds. It is a design that stands out for careful consideration.
Public design should be able to capture the history and time of space as it is. It is not just about demolishing it because it is no longer useful. Even if the use was also discarded, the history of the region remains intact in space and becomes a culture of the times. Innovative public designs can be created when capturing this. It should also provide citizens with a pleasant life and create a space where they can coexist with nature. Careful functions with alive details are also important. The High Line Ecological Park is harmoniously balanced with these three. The High Line has now become an indispensable local attraction in New York. Hollywood actors come and important events are held all year round. Above all, it has become a space that New Yorkers have no choice but to love. The abandoned railroad has become a beautiful green roof full of relaxation and romance in life.
A Green Roof is very important materials in modern architecture. It also increases the insulation effect of the building and relieves the heat island effect, not just stopping at what is beautiful. Of course, the surrounding air clears up. It increases energy efficiency and creates a pleasant environment. When rainwater such as waterfalls falls, it is also effective in reducing flood damage by absorbing it. You can also grow and eat vegetables grown by yourself using them for garden purposes. Wouldn't it be a pretty good way to become an urban farmer amid the growing number of returnees? Anyway, the green roof must be a useful way in many ways. Expanding green areas in cities is very important, and above all, human emotions can become richer on green areas. A desolate gray city gives you frustration just by looking at it. An alternative to solving this frustration is to add the greenery of nature as much as possible. Wouldn't this be another way to enrich the city's space and heal our hearts a little?
