​Building Stock Modeling – Assessing Energy Demand and GHG-Emissions Through Synthetic Building Stocks
​Interim seminar at the department of architecture and civil engineering, division of building technology.

Short description:
In Europe, the final energy demand and GHG emissions of the residential and commercial building stock is considered to make up about 40 % of the energy and emissions. At the same time it offers a large potential for energy and greenhouse gas (GHG) emission reductions. However, data availability and quality is poor to assess this potential in a reliable way on a large scale. Building stock models (BSM) offer a way to assess the energy demand and GHG-emissions of building stocks and develop pathways for energy and GHG-emission reduction. The most common approach to building stock modeling is based on building archetypes, which are taken as representing large segments of the stock. Based on these archetypes the future development of the stock is forecast through average refurbishment rates. This limits the conclusions that can be drawn to an average and aggregate level as average archetypes do not reflect the variability in the stock in terms of building sizes, states and usage and therefore may overestimate the actual reduction potential.

This thesis aims at addressing these issues by drawing on research on the generation of synthetic populations to generate a disaggregated synthetic building stocks. The developed methodology disaggregates aggregate national data and combines it with various data sources to generate a synthetic building stock that can be assessed through building stock modeling. The disaggregate stock data can more adequately represent the variability and heterogeneity in the building stock. This is the basis for a more accurate assessment of the reduction potential for energy and GHG emissions in the building stock as well as lays the basis for developing more detailed forecasts for the development of the stock.
