***General Introduction***
This dataset contains simulation results performed during June 2024- July 2024 at Delft University of Technology. This dataset was used to support the research paper titled Preparing for Lower-Temperature Heating: A multi-criteria framework to support decision-making for energy renovations of existing Dutch dwellings

DOI of paper: xx

It is being made public both to act as supplementary data for publications and the PhD
thesis of Prateek Wahi and in order for other researchers to use this data in their own
work.

This study was carried out with the support from the MMIP 3&4 scheme of the Dutch Ministry of Economic Affairs & Climate Change and the Ministry of the Interior & Kingdom Relations.

***Purpose of the dataset***
The purpose of the data is to support different stages of the developed decision support framework in aiding the selection of renovation solutions for preparing dwellings ready for lower-temperature heating. The simulation results were used to analyse the existing situation to establish benchmarks and assess new renovation solutions for LTH readiness.

***Tools used for data generation***
The dataset was generated using the parametric simulation workflow detailed in our earlier study and can be found in xx. The workflow is developed in Rhino 7 and grasshopper environment with Ladybug and Honeybee tools v1.6 for energy plus simulations. 

***Description of the data in this data set***

One Excel file containing eight tabs, namely : 
1. Description: Description of tabs and variables
2. Bench_HT: Performance of the apartment complex in existing HT (90/70degree) supply temperature to establish benchmark performance
3. Bench_LT: Performance of the apartment complex in LT (55/35 degree) supply temperature to evaluate LTH readiness and need for renovations. 
4. A1_A2_HT: Performance of original proposed solutions A1 and A2 in HT supply
5. A3&A4_LT: Performance of original solutions A3/A4 in LT supply.
6. A5_A14_LT: Performance of new generated solutions moderate : A5, A5R, A6, A6R, A7, A7R, A8, A8R and deep : A9-A14 in LT supply
