While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply

Economic analysts are starting to warn of the threat rising oil prices pose to Ireland’s recovery prospects.
