TECHNICAL BUILDING INSTALLATIONS (TBI)
Sewage, drainage, guttering, sanitary installations and gas
Water distribution network, sanitary installations, drainage, sewage and guttering installations, boiler rooms, and other.
Central heating systems
Refurbishments of boiler rooms. Heating using heat pumps for the municipal, multi-purpose and industrial constructions. Central heating: floor heating, radiator, panel, electrical, solid fuels heating, stoves / hot air distribution, accumulation and being equipped with hot-water piping and heat exchangers, preparation of hot utility water using stoves and fireplace suites having the hot-water exchangers, photovoltaic heating.
Air conditioning and air treatment
Air conditioning units and air treatment systems intended for family houses, municipal and industrial constructions.
Air recuperation
Air recuperation systems and air exchange management / controls for various structures, utilizing active air recuperation – escape heat entrapment.
Solar systems and environmental resources
Classic solar systems. Photovoltaic energy sources which serve the purpose of hot water preparation, electric heating and so-called island systems, where it is possible to distribute electrical energy into the grid of a building in question, eventually store it in batteries for instances of blackouts in the public grid. Furthermore, small-size wind turbines, windmills (power plants).
The selection taken with regard to energy sources may impact greatly on the overheads, operating costs, as well as the ecology and comfort of operations and controlling mechanisms, as well as the overall independence from the public distribution networks (sources of energies).
