Tenders Are Invited For Implementation Of Repair Activities Of The School Building St. St. Cyril And Methodius, S. Herakovo, Comm. Peony, To Improve Its Energy Efficiency

Implementation Of Repair Works Of The School Building St. St. Cyril And Methodius, P. Herakovo, Commune. Bozhurishte, In Order To Improve Its Energy Efficiency, The Following Basic Construction Interventions Should Be Carried Out: Energy Saving Measures An Energy Efficiency Report Has Been Prepared For The Site. The Following Energy-Saving Measures Are Planned. Thermal Insulation With Eps With Δ= 100 Mm And Coefficient. Of Thermal Conductivity Λ≤0.035 W/Mk On All Non-Insulated Facade Walls Thermal Insulation With Xps With Δ= 100 Mm And Coefficient. Of Thermal Conductivity Λ≤0.030 W/Mk Per Plinth Thermal Insulation Of Window Pages (Turning) With Xps, Δ=2 Cm, With Coef. Of Thermal Conductivity Λ≤0.030 W/Mk Thermal Insulation Of A Cold Roof With Stone Wool Mattresses, Δ=120 Mm And Coefficient. Of Thermal Conductivity Λ≤0.039 W/Mk. On The Floor Of The Attic Space. Replacing The Old Wooden Windows With Pvc Windows - Five-Chamber Double-Glazed Windows With Heat Transfer Coefficient Λ ≤1.40 W/M2k Replacement Of The Old Aluminum Windows With Aluminum Windows With An Interrupted Thermal Bridge And Glass Unit U≤1.7 W/M2k It Is Planned To Lay Strips On The Facade Of Stone Wool With Δ= 100 Mm, Coefficient. Of Thermal Conductivity Λ≤0.035 W/Mk And Density 100Kg/M3 For Dividing The Facade Insulation According To Fire Protection Requirements Thermal Insulation Of Bay Windows With Eps, With Δ= 100 Mm And Coefficient. Of Thermal Conductivity Λ≤0.035 W/Mk The Facade Thermal Insulation System Should Provide The Necessary Vapor Permeability In Order Not To Prevent The Evaporation Of Moisture Through The Enclosing Structure, As Well As The Retention Of Moisture In The Areas Of The Connections Between The Facade Panels. In Order To Meet These Conditions, Thermal Insulation Boards Should Have A Coefficient Of Water Vapor Transmission (Water Vapor Diffusion Resistance Number) Μ < 20. Plaster, Putty And Adhesive Mixture Should Have A Coefficient Μ < 70. It Is Planned To Build An Air Conditioning System Developed In The Hvac Section. The External Bodies Of The Air Conditioners Will Be Installed On The Facade And Will Be Drained Externally. It Is Planned To Build A Photovoltaic Installation On The Roof Developed In The Electo Part Of The Investment Project. Accompanying Measures Dismantling Of Old And Installation Of New Water Pipes Complete Plastering Of The Building From The Outside After Renovation And With Thermal Insulation. Before Laying The Thermal Insulation On The Facades, The Compromised Plaster Is Beaten And Removed To The Base, And Then Restored After Spraying The Base With Cement Mortar Or Other Suitable Materials To Provide A Strong And Level Base For The Thermal Insulation Boards. Installation Of Drainage Profiles On The Corners And Edges Of The Building. Installation Of An External Aluminum Window Sill Along The Entire Window Frame From The Outside, Turning The Pages With Gypsum Plaster And Plasterboard - From The Inside And Painting Twice When Installing The New Window Frame. The Full Description Of The Subject Of The Public Procurement Is Given In The Relevant Technical Specification - Annexes No. 1 Representing An Integral Part Of This Documentation.
