Green roofs and facades can reduce the temperature in an industrial hall by up to five degrees

Slavkov u Brna – A green roof and green facade on an industrial hall can reduce the internal temperature by up to five degrees Celsius compared to a conventional hall. Additional cooling with air conditioning then also consumes less energy. This was stated for ČTK by Libor Musil, founder of the construction company Liko-S from Slavkov u Brna. The company built an industrial hall with a green facade and roof on its premises.

"Inside the hall, greenery makes a five-degree Celsius difference compared to a regular metal hall without greenery. The exact value depends on the area of greenery on the walls and roof, the size of windows and doors, and the operation of the hall. To cool down, the green hall LIKO-Street requires half the amount of energy compared to a comparable hall without a green facade. Plants, due to evaporation, generally do not exceed a surface temperature of around 30 degrees, while facade materials heat up to 60 to 80 degrees Celsius in summer and radiate heat to the surroundings. This then enters the hall when doors, gates, or windows are opened, the air conditioning has to work with it, its efficiency decreases, and energy consumption rises," explained Musil on the benefits.

This is the third green building that the company has constructed on its premises. It replaced one of the oldest production halls in the area. In addition to the green facade and roof, it also works with water and has photovoltaic panels installed on it.

One of the main goals of the new hall's design was to limit overheating and reduce the need for active cooling. The green facade shades the surface of the building in summer, supports water evaporation, and improves the microclimate in its surroundings. The biosolar roof also reduces the thermal load on the structure, helps retain water on-site, and connects vegetation elements with energy production.

The photovoltaic power plant with a capacity of 60 kilowatt-peak has part of the panels installed vertically. As a result, it does not produce the most energy around noon, as with the usual sloped installation, but in the morning and afternoon. This better covers the consumption of the production plant at times when energy is usually more expensive.

The LIKO-Street building not only complements the company's premises, but also practically demonstrates the use of technologies that the construction company offers to its clients.

Liko-S is a family-owned company that was established in 1992. It focuses on the development and production of construction systems, living buildings, and custom processing of stainless steel, as well as other contracts for industrial companies. In addition to branches in Prague, Bratislava, Budapest, Polish Cieszyn, and Vienna, it also has a small factory in Bengaluru, India, where it manufactures building partitions.
