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 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.
