Improved Umbrella formula (UF+) and improved modular Integrated formula (mIF+)

After some improvement work in notations, grouping terms, and adding some more clarifications since July, we provide here an improved Umbrella formula (UF+), that allows by parametrisation to tailor a formula with specifc properties, including an improved Integated formula (IF+) – which we see conceptually as strong – but also several other formula. Access the new Briefing note for free here: Improved Umbrella formula (UF+) and Integrated formula (IF+). Please see also our presentation made at the 3rd Environmental Footprint EoL WS in Somma Lombardo in September 2016 that includes in addition the modular improved Integrated formula mIF+ for use in EN 15804 context, moreover in a clearer notation.
