REVIVAL Objective

• The global objective is to show that tertiary
  buildings from the post-war pre-energy conscious
  era, can be refurbished economically, with
  improvements in energy performance that lead to
  lower life-cycle CO2 emissions than the original
  building, or an equivalent new building. Thus
  refurbishment would make a significant
  contribution towards the EU policy of meeting the
  Kyoto protocol.

Objective WP9

• To identify a life-cycle CO2 assessment
  procedure which is sensitive to the emissions
  associated with the manufacture of materials,
  transportation to site, construction, energy in
  use and maintenance, final demolition and
  disposal of wastes.
• To apply it to the refurbishment of the existing
  building and make comparisons with the reference
  case of demolition and new-build.
• To assess and report on general environmental
  results of refurbishment

The following reference values can be used

•   Good It can be considered as the performance
  of the best 25 buildings on the building stock.
  Can also be considered as a value typical of the
  requirements of energy performance regulations
  for new buildings,
•  
• Typical Also called Building stock reference.
  This corresponds to the energy performance
  reached by approximately 50 of the national or
  regional building stock (median value).
•  
• The reference values are defined at the national
  or regional level.

14
Conclusions preliminary results

• Besides lower initial CO2 emissions, in 2 cases
  the renovated REVIVAL Building has lower annual
  CO2 emissions than the Newbuild equivalent, due
  to lower annual energy use (Albatros
  Daneshill).
• In all cases the renovated REVIVAL building shows
  lower CO2 emissions than the existing building
  within the first 5 years.
