Samenvatting

In this document the research justification of the showcase was created. The research shows to what extent Bax-shop still has to improve their buildings to obtain a certain energy building label which is a directive (the European Energy Directive given by the European government to all its member states and underlying companies that roughly explained, share the size of Bax-shop or are bigger. Therefore, Bax-shop has asked to find out in what way and at what costs they can comply to this directive. This research was done in relation to energy efficiency, return on investment, prime considerations and improvement costs per building. Following from these sections, four information gaps were identified as basis for the execution of the research:
1. The extent of options to increase energy efficiency and energy savings in buildings from Bax-shop.
2. The extent of best solutions in comparison to the costs that are made by executing this solution, in other words, the return on investment on each solution.
3. Whether the prime considerations for improvements are equal to every building or if there are huge variances that needs different approaches to each building.
4. The extent of the same improvements towards an individual building being of the same costs per certain unit or these unit prices differentiating due to other circumstances of each building.
To answer these questions, mostly literature research was performed but still some field research was necessary. Due to the limitations of the coronavirus a lot of research options were discontinued and had to be desk researched, some field research could be done by surveys that were given to employees in other parts of the buildings since it was not allowed to go to different departments of the buildings at the time of the outbreak. The desk research was validated by comparison with different sources and the field research were simple check lists that were filled in by people with more knowledge in the area than the average person. These checklists were colour coded and translated into a usable source of information.
Results show that Bax-shop already has an above average standard of building quality in one building and that there is still some work to do on their other property. Building “A” (Olympiastraat 2-4) has obtained in current state label “A”, which means this building already has the aspired label which is needed in 2030 and would not need further improvements, but further improvements like cheap and efficient are recommended. Building “E” (Verrijn Stuartweg 18) has obtained in its current state label “E”, which means that this building is quite fare below the standard (label “C” that has to be obtained in 2023. It is recommended to at least improve this building to this standard with a total investment sum of ± €22.725,99.
All recommended improvements could be implemented within a time span of a few weeks, given that everything is done at the same time and insulation takes the longest time to complete. Furthermore, it has to be installed before the year 2023 and the best timeframe to implement changes would be Q1 or Q2 of each year since the client of this research has said it to be the quietest time of the year. Taking these recommendations into account, Bax-shop will comply with the EED and therefore reach its goal to comply with this directive before the year of 2023.
