Energy savings achieved through the improvement of metering and billing of individual consumption of heating/cooling and domestic hot water in multi-apartment and multi-purpose buildings can make a contribution to the scaling up of efforts to achieve the energy efficiency targets of the EU in 2020 and beyond.
Having reliable data and indicators on how energy is used is key to informing and monitoring the effectiveness of energy efficiency policies. Highlighting the importance of such data, the IEA has for the first time published an Energy Efficiency Indicators database with annual data from 2000 to 2015.
Sustainable urban renovation is complex, particularly with respect to the decision making process, where a number of key stakeholders and several aspects need to be considered simultaneously. Evaluating and selecting alternative scenarios or measures to be implemented can be a substantial use of time and resources for cities.
For a sustainable, safer and more competitive Europe
The primary objective of this paper is to present the use of a steady model that is able to qualify and quantify available natural ventilation flows applied to the energy retrofitting of urban residential districts. In terms of air quality, natural ventilation presents more efficient solutions compared to active systems.
A new International Energy Agency (IEA) book Energy Efficiency Market Report 2015 reveals that energy efficiency improvements since 1990 in IEA member countries avoided 870 million tonnes of CO2 emissions in 2014 – and a cumulative 10 billion tonnes over the last 25 years, roughly equivalent to current annual emissions by all IEA member countries
Renovation in Practice
If energy efficiency rules and eco-design product standards were harmonised across the globe, the savings in energy and greenhouse gas emissions would be enormous, a new European Commission study has found. Up to 7,600 TWh of electricity would be saved by 2030 – a 13% reduction on the business as usual scenario
