Main technical characteristics of ASTRAL BUSINESS CENTER
Facades and Roofs
The outer contour of the building features ovals and acute angles to resemble the shape of an eye developed as a decorative element on the roof. This remarkable design has made ASTRAL BUSINESS CENTER one of the most prominent and innovative structures in Bulgaria.
Up to the +9.00 m level, a suspended façade has been constructed from ETEM E-85 aluminium profiles integrating two-barrier low-heat-transfer double glazing and thermal panels made from non-combustible PVDF-coated ENF sheet in the thick sections zone.
An innovative technology uses the energy-saving double façade system for solar protection, for overheating/overcooling prevention and for energy efficiency improvement.
The façade concept for the tall section consists in the construction of a specific double skin façade system offering the following advantages:
- Buffer for overheating prevention;
- Wind protection;
- Solar shield;
- Natural ventilation/cooling during the summer months;
- Energy efficiency;
- Mechanical protection of the inner façade.
The double skin façade consists of an outer ‘skin’, an inner ‘skin’ and an air layer between them. The outer skin is a laminated tempered glass panel – 12/1.76/12 Pl.B.Linea Azzurra and
10/1.76/10 – Pl.B.Linea Azzurra – with integrated sun protection print having 34.5% density.
The inner skin has been constructed from ETEM series E-45 façade aluminium casings and railing strips from ELVAL ENF TM aluminium sheet (non-combustible PVDF-coated ENF sheet) and high- quality thermal insulation.
The ELVAL ENF TM aluminium sheet is non-combustible and fully compliant with the international regulations concerning the fire protection of buildings and construction materials.
Similar double skin façades have been constructed for two other buildings in the world: the
Salvation Army Headquarters in London and the Munich Reinsurance Company building.
The roofs are flat, with intensive greenery. For this purpose, the thickness of the light weight soil substrate above the showroom is 60 cm allowing for low and medium-sized trees to be planted. The vegetation planted on a 35 cm soil layer on the +32.67 m level will contribute to the reduction of the harmful СО2 emission to the atmosphere and will also protect the last floor against overheating or overcooling.
Synergy of spaces and integrated services for their users
The building features 10 overground and 2 underground levels containing areas with different functions aimed at a lasting mix of mutually beneficial services.
The first-class commercial areas suitable for showrooms are located on the ground level and have large windows facing the street.
The business restaurant with coffee lounge and panoramic terrace on the second floor has been designed to cater for both the people working in the building and their business associates.
The guarded indoor car park guarantees the safety of personal and company vehicles.
The centralised management including maintenance of the communal areas and systems, cleaning and security, guarantees the high level of customer care and occupancy and security standards.
