Methodology Applied to the Evaluation of Natural Ventilation in Residential Building Retrofits: A Case Study

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. 

Energy efficiency a route to a competitive and climate conscious world

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

IEA Energy Efficiency Market Report 2015

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
