In the Hysopt software, the Pareto analysis can be started by clicking on the icon on the left side of the screen.
...
Model selection
After clicking on the Pareto icon, a new page is opened with on the left the folder structure. In the folder structure, the user can navigate to the models desired to analyse.
...
After selecting at least two models for the Pareto analysis, the selected models are visualised on the right side of the screen. If a model is selected which isn’t desired, it can simply be removed by clicking on the “garbage bin” icon.
...
Specifications
After the model selection, the user should click on the “next” button on the top right corner of the Pareto dashboard. A new page will appear with the selected models on the left.
...
Besides adding comments to models and changing the order of the models, a reference model should be selected. A reference model is needed to calculate different aspects like for instance “energy cost savings”. A model can be selected as the reference by clicking on the “Reference” button next to the models' name. After selecting the reference, the button turns blue.
...
Parameters
If a reference model is selected, the user can click on the “next” button on the top right corner of the Pareto dashboard. A new page appears with different parameters. The user should change these parameters if the correct values are known. The parameters are used for different calculations done in the Pareto analysis.
...
If the user has entered the correct parameters and clicked on the “next” button, a new page appears with input fields for the investment cost. The user should insert the correct material, installation and study cost for correct investment analysis.
...
Pareto analysis
After the implementation of all the necessary information, the Pareto analysis can start by clicking on the “start” button in the top right corner. In the new page, a Pareto graph is shown with the “Energy Cost” and “Discomfort”.
...
On the left side of the page, there are 3 different sections “Energy”, “Comfort” and “Investment”. Every section can be further analysed by clicking on the “Open” button.
Energy
First, the installed power of all the production units is shown with the percentage below.
...
Finally, the CO2 emissions are calculated with the emission factors for gas and electricity. And with the emissions, the reductions are calculated.
...
Comfort
In the “Comfort” section, the general comfort aspects are visualised. The comfort ratio is the percentage of people who are satisfied with the delivered heating and/or cooling. The comfort improvement is calculated compared to the reference. The discomfort ratio is the percentage of people who aren’t satisfied with the delivered heating and/or cooling. The comfort class and main class is calculated and visualised. A detailed explanation of how comfort is quantified is found in Pareto calculations.
...
Furthermore, the number of zones with a certain class or main class is visualised with the percentage compared to all the rooms.
...
Investment
In the “Investment” section, the optimisation costs are summarised with the calculated Hysopt project fee. The optimisation costs are implemented by the user in the parameter page. The calculation of the Hysopt project fee is explained on https://www.hysopt.com.
