• PASSIVE HOUSE FOR 100 APARTMENTS - 2012. - Budapest

    The first certified Hungarian passive house with 100 flats has been completed in District XIII on the corner of Zsinór and Jász street. The local government is going to operate the residential building as an apartment block, which is a pioneer in this scale not only in Hungarian but also in Central-Eastern European market.

    What is a passive house?
    for tenants: heating cost per year is 15-20 thousand forint
    for engineers:  certification of „Darmstadt Passivhaus Institut”, specific annual primary energy need under 120 kWh/(m2year), value of n50 airtightness pressure test maximum 0,6 1/h,  energy used for heating does not exceed 10 W/m2.

    Architectural concept
    A passive block of flats can be designed with a stairway, a balcony or a corridor access. We reinterpreted the traditional balcony access system. The horizontal circulation of the house is an open passageway interrupted by columns and bridges which are positioned around the inner courtyard enclosed by the building. The corridor is shifted from the windows of the flats to ensure separation. The distance is the largest along the residential block containing two roomed apartments, it is smaller next to the one and half roomed block, while the distance is the smallest near the studio flats. The two vertical circulation cores are separate elements located among the building blocks. A further benefit of the balcony access is that the spaces of flats can be cross ventilated and lit by natural light. A strict rationality of the flats dominates within the thermal envelope. There are three different apartment types in the three blocks. The two roomed with an area of 60 m2, the one and half roomed with 50 m2 and the studio flat with 40 m2. The building shows its colourful, public, bustling side towards the inner courtyard as a counterpoint to the strictness of the residential blocks. Colourful metal cladding sticks to the wall and continues as a suspended ceiling behind the visible concrete framed structure at the joining of the corridor and the bridge.
