5.4.6.2 System boundaries 92 Costs and Benefits of Green Public Procurement in Europe (Final Report) All costs which are accounted for by a typical cleaning service provider are considered (for included cost elements see section 5.4.3). Data quality requirements: § Time-related coverage: For this LCC study only cost data is used, which is not older than 1 year. § Geographical coverage: For this LCC study cost data is used which is representative for purchasing authorities in the selected member states (Sweden, Germany, Spain and Czech Republic). § Allocation procedures: General and administrative costs which cannot directly attributed to the cleaning process itself (e.g. costs for technical or administrative staff, taxes, etc.) are added to the direct costs for the cleaning process according a typical cost calculation of cleaning companies. The detailed calculation structure is laid down in section 5.4.3. 5.4.6.3 Results With an assumed average number of work days per year of 252 days, 49 the total surface area to be cleaned sums up to 7 182 m 2 per year. According to REFA time studies (REFA 2007), the performance index for the cleaning of such an office space is 87,3 m 2 per hour. It is assumed that the performance index can be applied to all selected Member States. A typical cleaning service provider thus will charge 29,4 hours per year to clean this office space. The following table summarises the assumptions and calculations. Table 94 Calculation of annual working hours to clean the defined office space Item Specification Source Surface area: size 28,5 m 2 assumption Number of work days per year 252 typical figure Surface area to be cleaned per year 7.182 m 2 calculated Performance index 87,3 m 2 /h REFA time studies Working hours needed for cleaning per year 82,27 h calculated The following table summarises the prices of the non green and green version of sanitary cleaning products in the selected Member States. 49 i.e. without weekends and bank holidays.
Collection of Evidence Related to the Costs and Benefits of Green Public Procurement (Part 1) Table 95 Prices of sanitary cleaning products in the selected Member States Price per 100 litre suds (use concentration) Difference non green version green version absolute relative Sweden 6,16 € 0,82 € -5,33 € -87% Germany 2,92 € 7,24 € 4,31 € 148% Spain 51,00 € 78,05 € 27,05 € 53% Czech Republic 1,99 €* 1,37 €* -0,62 € -31% * Price per litre of product As with all-purpose cleaners, the prices for cleaners for sanitary facilities in Spain are much higher than the prices in the other regarded Member States. This again results from the mostly much higher recommended dosage for the products (see also section 5.4.5.3). Unfortunately, for the Czech sanitary cleaners with eco-label no dosage information could be received. For comparability reasons the prices for sanitary cleaners in the Czech Republic therefore refer to 1 litre of cleaning product. The following tables give the annual costs for this cleaning process conducted in the selected Member States, differentiated according to the typical cost structure of a building cleaner.
