Climate Energy Jobs

More energy efficient buildings can

...reduce Co2 emission considerably

...reduce dependency on fossil fuels

...create thousands of jobs

More energy efficient buildings are needed – both in hot and cold climates

• Poorly insulated buildings inflate 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 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 by 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

Renovation: Energy modernisation

Potential in the EU alone:

• 460 Mt CO2 per year = Italy’s annual

emmisions

• €270 bn in energy costs

• 500,000 jobs

Barriers:• Low priority• Lack of knowledge• Funding• Low quality in craftsmen and contractors’ work• Owner/tenant dilemma

But... market forces need help

1010

• Strengthen energy requirements considerably

• Make the very-low energy our 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

Taking our own medicine

• Long history of being a socially responsible company• Production proces optimized to minimum energy consumption• All office buildings energy certified• All energy renovations with <7 years pay-back to be initiated within 3 years• Part of Carbon Disclosure Project• Extremely positive carbon footprint:

• Insulation saves more than 120 times the energy used • ...and stakeholders care!
