major reduction of energy use in non-residential buildings

The Total Concept method

combines economic efficiency and energy efficiency

starts with the property owner's requirement
of return on investment

and a careful analysis of the property

all the possible energy saving measures are carried out
in one package

Results in halving of annual energy costs


Co-funded by the Intelligent Energy Europe
Programme of the European Union


Analyse the building

Identify all possible energy saving measures

Make energy calculations for the measures identified

Plan the action package that meets profitability requirements


A number of measures can be done without preparations

Others must be designed and planned, carried out by contractors

Finalize work by performing thorough functional performance checks


Register energy use at least on monthly basis

Continue the follow up at least one year after handover

This project aims to demonstrate that large scale energy performance improvements in existing non-residential buildings can satisfy profitability demands set by the building owner/investor and thus become a market driver for major refurbishment of existing buildings towards Nearly Zero-Energy Buildings.

This project, together with many other European energy efficiency and renewable energy projects, is supported by the EU’s Intelligent Energy-Europe programme.

Strategic objectives of the project

To considerably reduce the energy demand in the sector of existing non-residential buildings and thus contribute to European 20/20/20- target by 2020. Through the activities undertaken in this project more building owners/investors, in public and private sector, are active in realizing major energy performance improvement in non-residential buildings.
