The EPB regulations imposed a calculation rationale for heating end use in residential buildings with people’s habits embedded as default values: whole protected volume heated, indoor temperature 18°C, ventilation and internal gains a fixed function of the protected volume, etc.
Of all parameters defining end use for heating in dwellings, user's habits introduce the largest uncertainty. The term rebound was introduced to cover the fact that improved efficiency ended in more spending. Indeed, lower annual heating costs in energy efficient residential buildings saw inhabitants, if they have to pay the energy themselves, demanding more thermal comfort.
This report describes the state of the art of solar and photovoltaic forecasting models used to facilitate the integration of photovoltaics into electric systems operation, and reduce associated uncertainties. The report represents, as accurately as possible, the international consensus of the Task 14 experts on the subject. Further information on the activities and results of the Task can be found at: www.iea‐pvps.org.Read full article
“Today, any buyer, owner operator or investor who is sophisticated in the wind industry speaks in terms of IEC terminology: a wind class, a turbine design class, turbulence levels, and so on. Everybody understands what is meant. The conversation is more fruitful and constructive and expectations are set more accurately.” Read full article
Hydrogen may be an attractive replacement for fossil fuels. It can be made from renewable and sustainable resources and its product is water. Its use permits countries to reduce their dependence on imported oil, lessen greenhouse gas emissions and improve air quality. Over 40 nations have active programs including Argentina, Australia, Brazil, Canada, China, the 28-member EU and countries within it, Iceland, India, Japan, Korea, New Zealand, Switzerland, Taiwan, the United States and Venezuela.

Proven building automation technologies (BAT) and building energy management systems (BEMS) have a crucial role to play in reducing the energy consumption and CO2 emissions in residential housing and service sector buildings.Read full article
Recently, the competitiveness of Photovoltaic (PV) as opposed to other electricity sources has improved considerably. In many situations, PV systems represent a profitable and relatively low risk investment opportunity. Nevertheless, a case-by-case analysis should be performed to properly evaluate each project.Read full article
This project evaluates climate and energy policies in non-EU countries and provides recommendations for policy opportunities in the country under study. However, the learning opportunity also goes the other way around - European Member States might learn from countries outside the EU.
Countries all over the globe are taking steps in the transition towards a sustainable energy supply
