On Tuesday October 6th in Brussels, REHVA organized a seminar on “EPBD: where are we now & what to improve with the review?” and John Woollett was one of a moderator of a panel discussion. Here are his thoughts on the presentations.
First presentation was “The EU heating and cooling strategy and its role in the EPBD review” by Mikko Iivonen, European Heating Industry EHI.
The EU needs to: i) reduce the dependency from 3rd world countries, ii) reach the 2030 and 2050 goals to decarbonise the economy completely, and iii) boost the EU economy.
The question is what are the investment tools to reach these goals? More analysis is need (does this mean the current analysis is incorrect or just lacking?).
The residential sector should by 2030 have reduced its PRIMARY energy requirements by 25%. But where shall this reduction come from? Just new buildings only will only increase demand, unless the old ones are removed. AIVC studies are shown the very real issue of mould growth in homes when heating systems are changed (say from oil burning heating system to heat pump), SBS may become an unwelcome guest.
EU28 population is approx 510M people, in 240M homes, of which 40% were built before 1960. Tertiary sector is 25%. The range of energy use is wide from 585kWh/(m2.a) per house built in 1920 in the UK to 24kWh/(m2.a) from houses built in Slovenia in 2005. Overall in 2012 heating is still the majority of primary energy use for homes and the minority for industry. How will this change in the coming years? Will co-generation become more important? District heating is a huge investment and requires a strategy spanning many years. How many countries are able to commit the this long term strategy?
An interesting innovation was the use of bio-algae to generate power.
