New apartments in Prague
YIT in world
We try to fulfil YIT’s mission in our projects: environmental friendliness is one of the keystones of the YIT philosophy and several environmental goals are set in the corporate strategy. We are looking for and implementing environmentally sustainable solutions during construction, as well as in the subsequent operation of the building. The so-called green construction represents a way to protect nature and the environment, while also bringing more comfortable and healthier living for its inhabitants.
As part of the ESG (Environment, Social and Corporate Governance) strategy, we have updated our standards in Environmental and Social areas as well as the Governance of public affairs.
Since 2019, we have also been focusing on reducing the CO2 emissions of our own activities as well as in all YIT projects. On the basis of SBTi, we have committed ourselves to reducing the carbon footprint by 50% by the year 2030. In all our projects designed since 2020, we record CO2 statistics and specify a carbon footprint.
We place an emphasis on environmental friendliness, which also saves money for citizens in the long term. For example, building F in the HYACINT Modřany project was even built in the most economical energy rating "A". And it was the first passive apartment building in the Czech Republic to receive the "Certified Passive House Project" certificate from the Passive House Centre and, after the final approval, the "Certified Passive House" certificate.
In order to obtain the certificates, it had to meet the very strict internationally-recognised criteria set by Germany’s Passivhaus Institute. Thus, Building F offers thermal comfort throughout the year, ensured by a system of controlled ventilation with heat recovery. The central recovery unit automatically feeds clean fresh air into the apartments without drafts. In addition, dust and dirt is filtered out of the incoming air, which is especially appreciated by allergy sufferers and people prone to illnesses.
The first project with a complex system of rainwater collection using a “soft infrastructure” in the Czech Republic was the KOIVU Zličín residential complex. The term “soft infrastructure” represents an ingenious system of accumulation, seepage, retention and evaporation surfaces that effectively uses rain water and prevents it from flowing into the sewer without being used. The water retained here is used, among other things, to irrigate the entire complex with an area of almost 30,000 m2 and thus to promote the growth of local vegetation.
We are building the VESI Hostivař project on the territory of the former Kaplan sawmill. Before the construction began, we removed almost a dozen dilapidated warehouse buildings and concrete area roads. At the same time, we destroyed the remnants of building materials and piles of rubbish that had accumulated in the crumbling halls. Our goal is to cultivate neglected areas and bring life back to places that lacked meaningful use.
In addition, we will be using “green” concrete, i.e., concrete where natural aggregate is completely replaced by a crushed mixture of demolition waste, for the first time in this project. Its main advantages include saving natural resources and the energy for their extraction, supporting the circular economy by using secondary materials and reducing the carbon footprint. Its lower coefficient of thermal conductivity also contributes to improving the energy performance of buildings. In the VESI Hostivař project, concrete from recycled aggregate will be used in the foundation as well as for some wall and filler constructions. This will reduce CO2 emissions by almost 3%.
In the framework of sustainable development, we also reconstruct old, dilapidated or unused objects. An example of this was the PARVI Cibulka project, which is being created by the conversion of the former Meopta factory into modern loft-type housing. The main aim is to highlight the industrial soul of the former factory. That’s why we are keeping the original structure with its size and proportions and retaining its industrial appearance with several elements, such as the original staircases, for example.
The PARVI Cibulka project stands opposite the already completed AALTO Cibulka residence. Both are connected by a shared reception and a private courtyard with a green park with a water element, a seating area and a playground for children.
On the site of the former garden colony on an area of nine hectares, we are building our largest project, SUOMI Hloubětín. Here we transformed the previously neglected brownfield area into a new modern city neighbourhood with almost 900 apartments. Commercial zones, new infrastructure and areas for leisure activities as well as rest areas are also going up in a modern complex full of greenery. For families with children there is also a children's playground and a new preschool.
In the SUOMI Hloubětín project, we revitalized part of the Rokytka stream, which we supplemented with a built in system of channels, furrows and seepage and retention tanks for the ecological management of water. Thanks to new meanders and flood plains, the revitalized section of the stream several hundred metres long provides better water retention while creating a natural biotope for aquatic animals, insects and birds. We transformed the neglected banks of the river into a relaxation zone that the general public can use for rest and leisure. First of all, however, we had to remove over 100 tons of waste, because the surroundings of Rokytka had been used as an illegal dumping site, and we also stabilised the slopes and created a new path. We also cleaned the bottom of the stream and we planted water plants in the meanders.
We installed the first ever prefabricated bathroom in a showroom apartment in the PORI stage of the SUOMI Hloubětín complex. We will also be installing them in apartments a little further away, in the DEMI and RANUA stages of the LAPPI Hloubětín project. Trucks bring the finished prefabricated bathrooms straight to the construction site and here the cranes insert them in the building structure. Before that, they are manufactured under strict supervision in a specialised factory, thanks to which everything is prepared in a more pleasant and safer environment.
