Energy number and table
• Definicion: Energiy number is the ratio between annual amount of used energy and usefull surface of the building.
• Formula: EK = Q / A = consumption ( kWh) / surface ( m2 )
• Result:A simple calculation shows energy efficiency of the building and encourage residents to take action.
Energy measures
Eko fund, reserve fund
• Slovenian environmental public fund, Grant financial incentives, Beneficiaries are homeownersThermal 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.
