Romania – Overhaul and refurbishment work – Execuția lucrărilor la obiectivul de investiții ”Creșterea eficienței energetice a blocurilor de locuințe A1 și G2, Strada Măgura, Geoagiu-Băi, Oraș Geoagiu, județul Hunedoara, COD SMIS 2021: 348245

**Residential Building A1 and G2**

**Thermal rehabilitation of the building envelope elements;**

**i. Thermal insulation of the façade - glazed part, respectively the replacement of the existing exterior joinery, including that of the access to the building, with high-performance thermally insulated joinery, replacement of the interior joinery: access doors and windows to unheated or insufficiently heated spaces if the case;**

**ii. Thermal insulation of the façade - opaque part, respectively the thermal insulation of the exterior walls, including the thermo-hydro insulation of the terrace or the thermal insulation of the slab above the top floor with thermo-insulating systems in case of the existence of the roof; Thermal insulation of the opaque exterior walls – by applying to the exterior a thermo-insulating material – mineral wool with a thickness of 20 cm;**

**iii. Closing of the balconies and/or loggias with thermally insulated joinery, including the thermal insulation of their parapets; Demolition of the metal grilles, balustrades and closures not corresponding to the balcony and loggia parapets, as well as the demolition of non-structural, decorative elements made of concrete; Closing of the parapet on balconies and loggias with masonry of 10 cm thickness, plastered and finished with washable plaster and gravel on the interior; Installation of new exterior joinery from PVC with thermally insulated glass of the triplex type, energy efficient, with thermal performance (treated low-E surface, inert gas filling between glass panes, radiant barrier) with R’min = 0.83 m2K/W, including the provision of the glazed façade with shading elements.**

**iv. Thermal insulation of the slab above the unheated basement; Thermal insulation of the slab above the unheated basement - it is recommended to use rigid thermal insulation boards of the type basalt mineral wool of high density, as a thermal insulation material with a thickness of 10 cm, which will be protected with 2 layers of plaster and a reinforcing mesh.**

**v. Thermal insulation of the walls that form the building envelope which delimit the heated space from other unheated common spaces; Insulation of the partitions and partitions with high-density basalt mineral wool with a thickness of 2 cm + protection with reinforced plaster mesh; Insulation of the building's plinth with mineral wool with a thickness of 20 cm and protection with a structured, waterproof but vapour-permeable mortar, with the extension of the thermal insulation with 40 cm below the CTS level;**

**vi. Other types of works: - repair of the protective sidewalk, in order to eliminate the infiltration of the infrastructure of the residential building; - hydro-insulation of the plinth and rehabilitation of the green area around the residential building, affected by the intervention works; - dismantling of the roofing and the wooden roof, dismantling and rebuilding the hydro-insulation layer at the accessible roofs, making the wooden roof and ceramic profiled roofing, including accessories, replacement of the rainwater collection system; - repair of the building façade construction elements that present a potential risk of detachment and/or affect the functionality of the building; - refurbishment of the interior finishes in the intervention areas;**

**Improvement/modernization of the building's technical systems: Providing apartments with ventilation grilles. i. Refurbishment of the ventilation ducts from apartments in order to maintain/achieve the natural ventilation of the occupied spaces, in case these have been blocked/closed; ii. Other types of works: Realization of a new electrical installation (for common areas) and the total use of LED type lighting bodies at the level of the common areas and the exterior lighting areas, having cells with a natural light sensor, powered by electrical energy from SEN; Realization of a lightning protection system and voltage arresters on the electrical power supply. Installation of a system for generating electrical energy with renewable systems of the type "on-grid" photovoltaic panels of 3 kWp/per each block.**
