St. Joseph School

A brand new building and a brand new school song, it's obvious party and with good reason: the building of the st. Joseph School in Leiden is ready.

The school has quickly transformed from a small school to a great school, because the number of students continues to rise. The atmosphere of the small elementary school has carefully considered to preserve the shape and appearance of the school. The philosophy of the school: openness, (lots of light and space), venue (hall, wide corridors) and colorful, plays an important role.

Unlike the existing building blocks that are very strict and straight, is a sculptural form to the school chosen by the interlocking of the masses and uithappen glass. The sculptural form ensures that the school, vocational, residential school gymnasium and knitting together.

It's become an aesthetic and social design. The design aesthetic is a relationship with the traditional buildings. The building thus becomes familiar and accommodating character with the neighborhood. The social character of the building is brought by the extracurricular activities of the BSO, the use of the gym by third parties and various gatherings.

Due to urban conditions, and the exterior is traditional, simple and effective. The interior is exactly the atmosphere that recalled the subdued character of the facade as a spectacle of natural elements to bring balance allows. The students imagine themselves in a familiar environment with numerous references to natural stimuli and finishes. The routing and layout of the building was produced by lower, middle-and upper-inseparable. The auditorium is where all groups meet. The space functions as a social platform and meeting point of the school. By placing an integrated stand among others, it is possible to organize school performances.

In one school, the health and wellbeing of pupils and teachers. The indoor climate plays an important role. This manifests itself again in air, light and space. By using floor-doors with a wide outside view, the natural character of the educational school close to the children placed. The ventilation system is over-dimensioned and provides sufficient fresh air in the classrooms. This is the CO2 content in the classrooms greatly reduced, which has a positive impact on the concentration of the children.

An essential element of sustainable design, the students and teachers well informed and to familiarize them with the sustainable measures in their schools are integrated. In this way awareness is created that the energetic aims the best guarantees.
Therefore we have an accessible education to the children about the various sustainable issues in their school. In this way they become familiar with the problems and we try to give them something in their further development.

 

A number of sustainable measures highlighted:

The durable design
The idea behind the design of the school is to create a sustainable school with good comfort, but a low energy demand. It was also striving to use no fossil fuels to heat the school. The school is heated by electricity. The purchase of green electricity makes the school energy-neutral 'is heated. The school is thus suitable for a flux-cored future. A good indoor climate is important to prevent future changes in the kinds of additional installations. Any change will cost extra material after all. Furthermore, in a later stage often a cheap and energy-inefficient solution considered (eg application of split units (air)).

Heat generation and cooling
The heat generation is done on a sustainable basis through heat pumps. Heat the extract heat from the source. There is no heating of the school through boilers. The source will consist of an open source system where groundwater is pumped through a heat exchanger. If heat pumps are used for a primary school usually have a vertical ground heat exchanger, which consists of about 50 snakes to be inserted deep into the ground ("closed system"). The heat takes place by means of a comfortable floor heating.
Outside the heating season with the source system can be cooled by the building heating and cooling floor use. Because the source without the use of a cooling unit cools the floor, this is an energy-efficient cooling method. The cooling provides a better indoor than usual for primary schools.

Ventilation
The building is ventilated by mechanical ventilation with heat recovery and exhaust air. This is a central air unit in the building. The air is blown draft-free, good ventilation is ensured, which is not dependent on whether or not to open windows and grids by a teacher.

Lighting
The rooms are illuminated by means of HF luminaires with daylight control. The toilets are lit by PL fixtures, switches switched by presence.

Building sustainable measures / concepts
Are essentially the sustainable aspects of the installations. However there from architecture and engineering sustainable profits. The most evident is the vegetation. This roof has a strong heat accumulating capacity, which regulates global warming. It also has an excellent roof water buffer effect and a positive effect on air quality. Reducing pollen in the immediate area is a pleasant side effect. Besides the vegetation has taken extra care to the comfort and the perception of the building. Good ventilation is clear, and the optimum use of daylight.
The energy burden in the future to minimize the building is designed with an EPC of 0.9, which is a reduction in the current building code requirements by 32%. In the period that the school is in use, it will be next energy costs, the costs of cleaning and maintenance also play an important role. The design and detailing have been taken into account, for example by using good materials to clean, easy to reach corners and maintenance facilities.
