SOCIAL EFFECTS AND OCCUPANTS‟ INFLUENCE- By applying renovation, the current social coherence of an area stays intact.- In case of renovation, the influence of occupants can be higher.- By applying renovation in a clever way, the inconvenience for the occupants remainslimited.- Large scale demolition and new development can result in segregation of socialclasses, which can lead to a concentration of lower social classes. In renovationprojects this effect can be avoided.- Nature areas are protected against cultivation3.4 EXISTING SUSTAINABILITY ASSESSMENT TOOLSOne of the main goals of this research is to develop a performance evaluation model forsustainable renovation concepts. Therefore, factors of influence on the performance ofsustainable renovation concepts are explored in this paragraph. For the identification ofimportant factors, four sustainability assessment tools that are currently used in theNetherlands are analyzed. Appendix M provides an evaluation of the quality of the fouranalyzed tools.3.4.1 GPR GEBOUWGPR Gebouw is a sustainability assessment tool that has been developed by W/EAdviseurs. GPR Gebouw focuses on three main aspects: energy, building physics, andenvironmental quality. Currently, about 150 municipalities and 150 commercialcompanies use the „GPR Gebouw‟ tool. By executing the GPR Gebouw assessment, thefollowing factors are taken into account:- Energy• Energy performance• Reduction of energy demand- Environment• Water• Environmental concerns• Materials- Health• Sound• Air quality• Thermal comfort• Light and visual comfort- User quality• Accessibility• Functionality• Technical quality• Social safety- Future value• Future-oriented facilities• Flexibility• Experience value3.4.2 BREEAMBREEAM (Building Research Establishment Environmental Assessment Method) has beendeveloped by the Building Research Establishment, which is a British research institute.BREEAM makes use of a qualitative weighing. The end score of a building can be pass,good, very good, excellent or outstanding. Hereby, the lowest possible score „pass‟ isequal to the legal minimum which is defined in the „Bouwbesluit‟ in the Netherlands.36
Currently, there are 330 BREEAM experts in the Netherlands, and 5 Dutch buildings areBREEAM certified. BREEAM considers the following aspects: (DGBC, 2010)- Management- Health- Energy- Transport- Water- Materials- Waste- Landuse and ecology- PollutionAppendix E provides more detailed information about the factors that are taken intoconsideration by executing the BREEAM assessment of a building.3.4.3 EPWIn the Netherlands, the official index for sustainability of buildings is the „energyperformance coefficient‟ (EPC). For houses, this EPC is determined with the sustainabilityassessment tool EPW. The calculations that determine the sustainability of a building areestablished in NEN norms. The EPC only considers the energy use that directly resultsfrom the house. This means, that the EPC evaluates the energy use that is needed for:- Heating the interior climate of a house- Cooling the interior climate of a house- Producing warm tap water- Lightning- Ventilation3.4.4 GREENCALCGreencalc has been developed by Sureac and evaluates sustainability on three themes:material use, water use, and energy use (www.greencalc.com). These themes aretranslated into one score, the environmental impact. A distinctive aspect of Greencalc isthat an integral life cycle analysis is the basis for the calculations. This makes it possibleto weigh and compare constructive and installation technical measures with each other.Greencalc takes four modules into consideration:- MaterialFor the determination of the environmental impact of a building, Greencalc uses lifecycle assessment (LCA) studies. An LCA gives insight in the environmental impactfrom cradle-to-grave. Next to quantitative information, also qualitative aspects ashealth, nuisance, and corrosion are taken into account.- EnergyThe energy module is based upon the norms that are used for the determination ofthe EPC, which is described in paragraph 3.4.3. These calculations are filled up byGreencalc, with the energy use that is not building bounded.- WaterThe water use is based upon the WPN (Water Prestatie Norm).- MobilityThe module mobility comes into consideration when districts are assessed. For asingle building this module is outside the scope of the calculations.37
