Annual Impacts Chart

This chart shows the annual carbon impacts or annual cost impacts (when using a life cycle costing tool) over the set calculation period of your project.

 

How do you use the annual impacts chart?

Navigate to the results page and scroll almost all the way down, there you will find the annual impacts chart. Most of the time the section with the highest impact will be the A1-A3 (the materials used in the construction of your project).

For the chart below we have used a BREEAM tool as an example (with a calculation period of 60 years), so it might display other life cycle stages which are not reported in other tools. The A1-A3, A4 and A5 emissions will always happen at the beginning of the calculation period of your project. Throughout the calculation period, there will be the annual consumption of energy (B6) and water (B7). Furthermore, any materials which are replaced (B4-B5) during the life cycle/calculation period of your building will be shown in the B1-B5 category. Any use phase emissions are also attributed to the B1-B5 section. Any annually exported energy (D2) will be displayed next to the energy usage. At last, the End of Life emissions will be shown at year 61 when the building is demolished.

All of the graphs can also be downloaded by clicking on the 'Download as image' button.

You can also take out several factors if you do not want to compare them, for that simply click on the category legend and you will get a different type of graph, in the example below we excluded the A1-A3 emissions to get a clearer overview of the replacements, annual energy and water usage and end of life emissions.
