Sustainable Education and Recreation Centre

Jury Award in the Adapterra Awards 2019

The new complex in Marki combines use of green energy, rain water and modern technologies to show that even education centres do not stay behind. Roof of primary school serves are water retaining swamp and all the buildings are surrounded by mixed greenery areas and trees with zones for rest and recreation.

Classrooms have AC units with heat recovery and their features such as blinds and lights can be controlled by a computer or mobile application. Buildings in the area are powered by combination of solar energy and gas combustion. The centre even received the BREEAM sustainability certificate.

The Adaptation Journey

 
The positive impact
This projects aims at temperature increase, heavy rainfalls and pollution by using water retention and greenery on the roof and within the complex. Solutions include using solar energy and gas combustion instead of coal burn for central heating and electricity.

Roof of the school building was designed as a multifunctional swamp roof. Extra collected water may be used for irrigating lawns or pumped back to the swamp during droughts.

The aim of the project is a sustainable ecological response to urbanization processes, creating a complex of educational, cultural and recreational facilities. A centre gathering local life, designating a local centre, attracting residents with its possibilities. One of the main goals is also to raise the youngest in the spirit of ecological thinking.
 
How does it work?
The water level in the swamp on the school building is maintained at 35 cm most of the year, which allows aquatic plants to grow. Evaporation from this container has a positive effect on the microclimate in the area and cools the building down during hot season.

A pioneer solution was used in this type of building. Large part of electricity is produced by a gas combined heat and power plant where gas burn temperature is used for heat exchangers for domestic water. In addition, 300 photovoltaic cells with a total capacity of about 67 kWp were located on the roof of the sports hall. Thanks to the different working hours of the facilities, the distribution of power can be implemented in the most optimal way.

To make each building a green one, it has been equipped with time switch lighting controls, water-efficient plumbing fixtures, a place for car sharing and electric car charging stations. Also high-quality ecological materials were used for construction, such as low VOC paints, recycled flooring and acoustic ceilings.
 
Original state
Before construction, there were abandoned forest bushes in the area, partly flooded during heavy rains. The area, in accordance with the urban planning assumptions, was intended for educational as well as recreational buildings.
 
Operation and maintenance
In general, operating costs are 16,000 PLN per year, including employment of extra staff.

During the design and implementation, some technological solutions were improved due to technological progress. This aspect should be taken into account at the planning and financing stage so that there is always room for improvement at the implementation stage.
 
Why was the measure chosen?
The original project from 2013 also assumed the use of ground source heat pumps, but changes over the years and the development of other sources gave the opportunity to reduce costs and abandon this solution.
 
Obstacles and challenges
One of the biggest challenges in designing was developing an optimal energy consumption plan. Choosing the most cost-effective sources of heating and reducing heat loss. Also fitting all those solutions into attractive building design that suits the needs of users. In addition, the time for implementation was limited due to the fact that education in Poland starts on September 1, so no delay could be allowed.
 
How much did it cost?
Overall costs were 110,885,665 PLN gross, return of investment is hard to calculate, as the public school is a part of the complex.
