Climate Energy Jobs
More energy efficient buildings can
...reduce CO2 emissions considerably
...reduce dependency on fossil fuels
...create thousands of jobs
3
More energy efficient buildings are needed – both in hot and cold climates
• Poorly insulated buildings inflate the need for heating when cold
– and cooling when hot
• In 2030, 70% of the world’s population (6 billion) will live in urban areas
• In 2030, CO2 emissions from buildings up 50%, due to a.o. increased use of air conditioning in the East and the US
33% of all energy in EU is used for transport
26% of all energy in EU is
used by industry
41% of all energy in EU is
used in buildings
2/3 of energy consumption in buildings is used for heating,
cooling and ventilation
Buildings are the biggest energy consumer and a major CO2 polluter

Passive Houses
It is easy with existing and proven technology to build houses that use 80% less energy than today’s average house!

Renovation: Energy modernisation
Potential in the EU alone:
• 460 Mt CO2 per year = Italy’s annual
emmissions
• €270 billion in energy costs
• 500,000 jobs
New legislation (EPBD2) tightens energy requirements
Sources: Ecofys, EURIMA
Barriers:• Low priority• Lack of knowledge• Funding• Low quality of craftsmen and contractors’ work• Owner/tenant dilemma
But... market forces need help
• Construction workers• Architects• Engineers• Building materials industry
Substantial energy modernisation will create jobs
• Strengthen energy requirements considerably
• Make very-low energy homes the standard choice (passive house levels mandatory in new UK buildings from 2013)
• Stimulus packages targeted at energy renovations
• Always make building renovations energy efficient
• Make public buildings energy efficient role models
Political leadership needed
The fight against climate change starts at home...
