GIS-tool
When a particular building (building X) contains more than one accommodation or address, the building is expressed as an apartment. When this is not the case, the adjacent buildings will be selected. When there is more than 1 adjacent building, building X can be identified as a row house. When building X has no adjacent buildings it is a detached house. If there is only 1 adjacent building, building Y will be selected. Select that building (building Y) and:
• Building Y has no adjacent property, property X is: semi-detached; • Building Y also has an adjacent building, building X is a corner house.
The diagram below shows the process of determining the type of housing, as described above.

Elaboration determination costs and insulation values
The costs were based on the basic methodology distinguished by Arcadis in the report ‘Actualisatie
investeringskosten maatregelen EPA-maatwerkadvies bestaande woningbouw 2017’. This report includes the updated cost- and insulation figures and the justification of the method used. The cost indicators are
differentiated by measure according to the type of housing (single-family house versus multi-family dwelling), by project size (single dwelling versus multiple dwellings / project-based), and moment of execution (standing alone versus during natural moment) and split into labour and material costs. The distinction based on house type is based on the established enveloping surfaces of the example houses and the quantities determined thereby. The existing housing stock can be classified to single-family homes (detached, semi-detached, corner- and row houses) and multi-family houses (apartments). For each section, based on this overview of reference houses with the corresponding surface areas, the average sample house is determined. Based on this sample house, the weighted average costs were determined (Arcadis, 2017).
This dataset was supplemented with cost and insulation values from Archidat. Archidat has an experienced team of architectural specialists and engineers. This team has developed extensive libraries with current building cost data that are tailored to the most common building types and activities. The Building Cost Online databases are continuously fed by the current cost and insulation information and expertise of hundreds of producers and suppliers. Thanks to the unique cooperation between Archidat and these producers and suppliers, they able to provide a comprehensive and comprehensive overview of current target prices and insulation values. The building cost system contains prices and product information of tens of thousands of articles, labour standards, building components and key figures regarding insulation values (Archidat Bouwkosten Online, 2018). The figures derived from both databases were benchmarked with the use of expert judgement.
Elaboration determination CO2 values
The CO2 emissions are based on the environmental classifications as stated on the online-database established by NIBE. NIBE is the Dutch Institute for Building Biology and Ecology. This database contains the various CO2 values per building material, used in the renovation measures (NIBE, 2015). The values shown in table VII.1 are derived from this dataset. The following aspects of the assessed emissions in the products are included:
• extraction and transport of raw materials;
• production and transport of materials and semi-finished products; • processing of production waste;
• transport to the construction site (standard 50 km); • losses on the construction site;
• processing of construction waste;
• emissions / leaches during the use phase; • maintenance and replacements of the product; • demolition of the product from a building;
• transport to the landfill, recycling or incineration plant; • processing in the waste phase;
• production and disposal of capital goods. Not included:
• production of excipients with a mass percentage of less than 1%; • transport of employees and equipment;
• human labour;
• maintenance in the sense of cleaning / cleaning. • Work on construction (NIBE, 2015)
