Actions Action 2.1. Selection of existing or

virtual reference buildings

Action 2.2. Environmental performance assessment of reference buildings

Action 2.3. Comparison of results and study of the influence of the use of the Code of Practice

Reference buildings 1st phase: Start with ‘easy’ exercise:

simple volume – one material CUBE

2nd phase: complete building: FUTURA House 3 versions of same building

3rd phase: virtual redesign of FUTURA House apply recommendations

Assessment of CUBE

Fixed parameters: dimensions, material (reinforced concrete), energy demand, …

Assessment: very divergent results! Different assumptions (volume, electricity type,

percentage of steel, …)

Various sources of basic LCI data

Other sets of result indicators
