Biurowiec Lakeside na warszawskim Mokotowie

PROJECT DESCRIPTION

The Lakeside office building in Warsaw’s Mokotów district is yet another example of harmoniously blending a building’s function with its surroundings. What makes this property stand out is the omnipresent greenery that fills every corner of the development and continues the landscape of the Służewiecka Valley. Thanks to carefully selected solutions – including extensive use of glass – the complex offers employees a bright, safe, and welcoming work environment, becoming a symbol of modern office architecture. The achievement of top-tier BREEAM Outstanding and WELL Gold certifications further confirms the use of high-standard building materials, taking into account both the comfort of the occupants and the energy efficiency of the property.

CHALLENGES

Selecting glass for the façade requires a comprehensive analysis – from the building’s intended purpose to minimizing energy demand during operation, through aesthetic considerations, and including resistance to wind forces, impacts, and thermal stress. The evaluation must also consider the human factor, meaning the choice of glazing should ensure end-user well-being through appropriate temperature, natural light, and optimal acoustics. The glass façade should also protect occupants from falling out, being injured by shattered glass in case of breakage, and safeguard against vandalism or attempted break-ins.

APPLIED SOLUTIONS

The Lakeside façade features triple-glazed units composed of COOL-LITE® SKN 176 II solar control glass, PLANITHERM® XN II thermal insulation glass, and STADIP® PROTECT laminated safety glass. This selection of coatings ensures optimal parameters for comfort, improved efficiency, and tenant satisfaction, as well as low energy consumption during building operation – regardless of the season. The low solar factor (g-value) of 0.34 for this glazing combination means that 66% of solar energy is reflected outward, resulting in reduced air conditioning costs during summer and increased thermal comfort for occupants. At the same time, the low thermal transmittance (Ug-value) of 0.5 W/m²K ensures that solar heat gained in the winter is retained within the building instead of escaping through the glass partition. The glazing units also provide access to natural daylight – with a light transmission (LT) value of 61%, the interior is well-lit with daylight, reducing the need for artificial lighting.

Lakeside blends seamlessly into its environment and complements it. The glass selected for the façade helps minimize the building's massiveness, while its shape echoes characteristic features of the surrounding architecture. While Lakeside draws attention with its designer concept and impressive glass façade, the laminated safety glass is the silent hero, standing up daily to changing weather conditions and potential threats in the name of occupant comfort, health, and safety.
