Bygherrernes Indkøb af CO2-reducerende Byggemetoder: En Socioteknisk Analyse af Indkøbets Effekt på Innovationen af CO2-reducerende Alternativer

Abstract

I dette speciale undersøges danske bygherrers praksis for at indkøbe CO2-reducerende byggemetoder. Frank Geels’ (2002) Multi-Level-Perspective model (MLP) anvendes til at undersøge hvordan tre niveauer af rammevilkår påvirker bygherrernes indkøbspraksis. Disse indkøbspraksisser anskues i et innovationsperspektiv gennem Elvira Uyarra og Kieron Flanagans (2009) fire indkøbsformer, for at undersøge generelle tendenser blandt bygherrerne, i indkøbet af byggeprojekter. Kategoriseringen sammenholdes med Frank Geels og Johan Schots (2007) definitioner af transitionsspor, for at analysere indkøbets effekt på byggebranchens udvikling af CO2-reducerende byggemetoder. Data er indsamlet gennem kvalitative interviews med repræsentanter fra forskellige bygherretyper, bygherreforeningen og en statslig ejendomsforvalter. Det empiriske materiale suppleres af litteraturstudier af branchespecifikke- og teoretiske kilder, til at understøtte analysens resultater. Analysens resultater viser at bygherrerne i dag oplever et pres, der tillader en gradvis omstilling til CO2-reducerende byggemetoder, hvilket resulterer i at bygherrerne primært indkøber standardiserede produkter, der tilpasses rammevilkårenes krav om CO2-reduktion. Diskussionen udfordrer dog dette pres ved at præsenterer faktorer, der potentielt kan medvirke et større pres for omstilling, hvormed bygherrerne ikke nødvendigvis kan indkøbe standardiserede produkter. Derfor præsenterer specialet en model hvormed bygherrerne kan samarbejde med andre aktører i byggebranchen, for at udvikle og afprøve ny teknologi i et økonomisk forsvarligt miljø.

In this master's thesis, we investigate the practices of Danish construction clients in procuring CO2-reducing construction methods. Frank Geels’ (2002) Multi-Level-Perspective model (MLP) is utilized to explore how three levels of framework conditions affect the clients' procurement practices. These procurement practices are viewed from an innovation perspective through Elvira Uyarra and Kieron Flanagan's (2009) four procurement types to examine common tendencies among the clients in procuring construction projects. The categorization is compared to Frank Geels’ and Johan Schot’s (2007) definitions of transition pathways to analyze the effect of procurement on the Danish construction industry’s development of CO2-reducing construction methods. Data is gathered through qualitative interviews with representatives from different types of construction clients, the Danish Association of Construction Clients, and a governmental property manager. The empirical material is supplemented by literature studies of industry-specific and theoretical sources to support the analysis results. The results of the analysis show that construction clients today experience a pressure that allows for a gradual transition to CO2-reducing construction methods, resulting in clients primarily procuring standardized products adjusted to the framework conditions' demands for CO2 reduction. The discussion challenges this pressure and presents factors that potentially could exert greater pressure for transition, where clients may not necessarily procure standardized products. Therefore, this thesis presents a model whereby clients can collaborate with other actors in the construction industry to develop and test new technology in an economically responsible environment.
