Hotel for the Radisson Blu chain
Radisson Blue Riverside Moscow is a competition project developed by za bor architectural studio for the new Radisson Blu hotel in Moscow. The emphasis is on a simple but effective graphic solution for the facade and efficient use of resources in the operation of the complex.
The building is designed as two blocks united by a two-storey stylobate. Hotel rooms (346 rooms in total) are located on floors three to eighteen; parking and car wash are located on the underground floors. The stylobate has two floors, where the hotel lobby, restaurants, business and spa centres, swimming pool, offices, laundry, other recreational, service and technical premises are located. The hotel lobby is designed as a two-light space, with the main element in the form of coniferous trees “sprouting” through the two floors. The window around the trees, in addition to the aesthetic function fulfils the role of a light well, providing additional insolation of the lobby. Since the main natural advantage of the site is its proximity to the water, the projected hotel buildings are maximally turned towards it with their main facades. Thus, almost all rooms have a view of the river.
The facades are hinged ventilated. The roof is flat, with internal drainage.
The main entrance to the hotel is on the first level. The roof of the second level (floor) of the stylobate is covered with lawn, and is used as a recreational area, allowing access to the river, and the terrace of the summer restaurant. In case of emergencies, it can be used for access of vehicles of rescue services.
The aesthetic solution of the facade is based on geometric ornamentation. In daylight the facade has a pronounced rhythmic pattern, in the evening it is painted in warm colours. And at night, due to the gradient lighting system, it is covered with soft light spots, reacting to the switching on and off of the windows in the rooms. In this way, the hotel will have an attractive appearance at all times, which will help the building to become a landmark and, as a result, attract more guests.
To reduce construction costs, aluminium ventilated façade systems were used, with standard modules based on the Aventa system, locally manufactured. Almost all windows are of the same size, which significantly reduces construction costs. White facades will reflect most of the ultraviolet rays, which will significantly reduce the average temperature in the premises, which in turn will reduce air conditioning costs in the summer season. The insulation used in the curtain wall system will reduce seasonal temperature fluctuations in the premises, which will also contribute to reducing air conditioning and heating costs.
In addition, standard presence detection systems should be installed to switch off unused electrical appliances and lighting.
Since a building of this height requires sufficiently high water pressure to supply the building with water, it is rational to organise a combined water supply system. For the upper floors it is proposed to use water pressure and water-pneumatic tanks, on the lower floors (where the maximum water intake occurs – laundry, car wash, swimming pool, kitchen) it is possible to use the main water supply system. The power supply of the water lifting plant and air compressors should be active mainly at night to reduce energy costs.
Since the hotel has a swimming pool and an ornamental pond on the nearby territory, it is reasonable to use it for bio purification (with the help of natural filters and higher plants) of ozonated or chlorinated pool water with its subsequent intake for watering plants on the hotel territory. In addition, a floor-by-floor circuit of grey water with low pollution is proposed for reuse after the coarse filters for drainage.
