EPB: calculations largely overestimates real use

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.
 
Measurement of heating end use in hundreds of dwellings and transposing it to the EPB reference year now showed the EPB largely overestimates real use.Read full article

Human habits and energy consumption in residential buildings

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.
 
Direct rebound has major consequences.Read full article

Electropedia: A Shared Understanding

“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.”

The Global Potential of Hydrogen

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.  Althoug

Medium Size PV Plant

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.

Energy and climate policy screening in comparison to the EU

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.Read full article
