The Energy, Climate Change and Planning Acts 2008
The Climate Change Act sets a mandatory carbon
emissions reduction targets of 80 on 1990 levels
by 2050, a move the UK has led the world on. It
also sets up a new Climate Change Committee,
regular 5 year carbon budgets, the potential for
the inclusion of shipping and aviation emissions
in targets, charges on single-use carrier bags,
and regular mandatory reporting of progress
towards climate change adaptation.

Climate Change Act Energy Act

• 80 reduction in greenhouse gas emissions by 2050
• Carbon budgets (34 by 2020)
• Feed-in tariffs
• Smart metering required
• Renewable heat incentive financial support for
  renewable heat generation
• Promoting de-centralised energy generation

Why Change Part F ?

• Proposed technical changes for 2010
• Harmonize changes with Part L and ensure that
  health standards in Approved Document F are not
  undermined
• Changes focus on new dwellings
• New requirements/guidance is provided for
• The installation and commissioning of ventilation
  systems
• Sound levels from continuous mechanical
  ventilation
• The ventilation of more airtight dwellings
• ADF guidance has been designed to work at assumed
  permeability of 3 m3/(h/m2) at 50 Pa
• Making domestic ventilation systems a controlled
  service

40
Carbon Reduction Commitment (Cap and Trade)

• Organisations with energy use over 6,000MWh/year
• Mandatory emission trading to cut carbon
  emissions
• Includes Local Authorities
• Scheme begins in 2010
• Published league tables

41
Feed-in Tariffs (Clean Energy Cash Back)

• Money for generating electricity on site
• Launch April 2010
• All electricity generated on site attracts the
  tariff (whether exported or not)
• Install now to get maximum tariff
• Start off tariffs will be fixed and guaranteed
  for life of project

42
Decentralised Energy Heating, Cooling and Power
Demonstrate that the proposed heating and cooling
systems have been selected in accordance with the
following order of preference 

• connection to existing CCHP/CHP distribution
  networks
• site-wide CCHP/CHP powered by renewable energy
• gas-fired CCHP/CHP or hydrogen fuel cells, both
  accompanied by renewables
• communal heating and cooling fuelled by renewable
  sources of energy
• gas fired communal heating and cooling.
