4xE Energy number - indicator Eco fund, reserve fund - money European project AFTER – scientific analysis Energy renovation – exemples
Energy number and table Definicion: Energiy number is the ratio between annual amount of used energy and usefull surface of the building. Formula: E K = Q / A = consumption ( kWh) / surface ( m 2 ) Result: A simple calculation shows energy efficiency of the building and encourage residents to take action.
Eko fund, reserve fund Slovenian environmental public fund, Grant financial incentives, Beneficiaries are homeowners Thermal insulation and heating systems Reserve fund of each building Our role as a manager: representation and implementation in the process and efficient spending of reserve fund
European project AFTER Cost Optimum and Standard Solutions for Maintenace and Managment of the Social Housing Stock 18 partners from 6 countries Analysis and optimisation of energy saving measures Objectives: immediate additional savings of 5-7% of energy, contribute to the 20-20-20 by 2020 in EU
Energy renovations of buildings Energy refonovation-whole package of energy saving measures: thermal insulation of facades, roofs, ceiling,sealing windows, thermostatic valves and balancing, increase awareness of residents The word recovery means in our case thermal insulation of facades to the standards and practices in the period of performance.
