I’m calculating Life Cycle Assessment Leve(s) for a building build in 2013, at that time building ha 15kW photovoltaics, and in 2024 the amount was increased to 185 kW photovoltaic system.
How I can configure these dates in building materials and energy consumption?
At the moment is it not possible to include materials or energy to be considered from a specific timeframe onwards. The best way to achieve the total emissions for such a calculation would be to include this in two separate designs and summarize the totals. Do note that with such an assessment you should take care not to double count the transportation and end-of-life emissions of the products.
I have forwarded your suggestion to our product management team to consider for possible future additions to the calculation options.
