PLATINUM Certified


    The BPS Office Building 15 is a new construction. The project consists of a single office building rising above the ground level, two underground floors and a central atrium space crossed by bridge connections, providing evacuation routes from the inside of the building. The two underground floors of the building are designed as parking space for the employees and the visitors, storage rooms, technical and service premises. The ground floor provides two independent entrances to the office floors, an office space in the northern part of the floor, a cafe, a restaurant, two fast food restaurants with free access from the outside.

    Heating and Cooling

    Тhe heating of the building is provided by the central district heating systems via local district heating substation equipped with control and safety fittings. The hot water is distributed via four pipe water distribution system to the building’s fan coil units. The cold water for the air conditioning of the building is provided by four air cooled chillers installed on the roof of the building. Each chiller is provided with two buffer tanks and an expansion vessel.

    Ventilation of the office premises is established via four air handling units with rotary regenerators, located on the roof. The four AHUs provide an outdoor airflow volume of total 32 125 l/s. Each unit consists of two fan sections (supply and exhaust), rotary wheel recuperation section and two F7 filter sections. The ventilation of the ground floor premises is performed through recuperation units for the Fast Food area and Lobby and AHUs for the Restaurant and Café. For the garage exhaust ventilation and smoke extract ventilation via directing jet fans and two main ventilators is established. The fans work in parallel and the amount of the exhaust airflow is controlled by frequency inverters according to the degree of air pollution. In case of emergency the main and jet ventilators operate at maximum speed in order to provide 6-fold air exchange.
