Abstract:This research identifies the considerations of housing associations to adopt energy-efficient housing retrofit concepts for row houses and tenement houses. Housing associations improve their housing stock to reach a mean energy label B in 2021 to fulfill the government agreement “Meer met Minder” (VROM, 2008a). The Dutch government realizes this in between objective to complete their policy within the European Performance of Buildings Directive which requires an energy neutral building stock in 2050 to reduce the carbon emission. In spite of the governmental measures, energy prices rice between 1997 and 2012 from 120% towards 35% for inflation (CBS 2012), this motivates housing associations to improve their dwellings thoroughly. The Dutch Housing stock has a mean energy label D (Senternovem, 2012). Obsolete dwellings with an energy label G or F consume an average amount of 2000 m3 gas each year and with the rising energy prices they are prohibitively priced for their target group with an income of €33.614,- a year (BZK 2013). The agreement “Meer met Minder” and the rising energy prices breaking through the vicious circle of blame where the housing association has not the interest to reduce the tenants energy consumption which is called as the split incentive problem (Mlecnik et al., 2010). Due to the agreement and practice from high level retrofit projects, construction firms develop industrialized concepts to improve dwellings in a single interference from energy label G, F, E to A or A++ (passive house). Despite the improvement assignment, the adoption of housing retrofit concepts in housing association projects is often limited to a single pilot project and sequential large scale serial projects fail to appear (Van Hal, 2000). The reduction of carbon emission, the control of the reside payment and the housing retrofit concept development in the construction industry have the interest to identify the considerations of housing associations to adopt energy-efficient housing retrofit concepts. This basic assumption form the objective in the research project: “Identify factors that influence the adoption of energy-efficient retrofit concepts for row houses and tenement houses by housing associations”. Literature about the social, economic and technical environment in the housing association sector and innovation adoption mechanisms shape the theoretical point of departure for this research project. The present housing stock performance is based on the Dutch housing regulation (Woningwet) and subsidiaries from the Dutch Insulation Program ((SNIP), 1988). Last decade the Dutch government stimulates the development of energy reduction technology with the EOS demonstration subsidiary. Housing associations applied the subsidiary for retrofit concepts to increase the comfort, esthetic and energy performance of their dwellings with an entire new construction quality as result. Housing retrofit deviates from the traditional renovation approach applied by housing associations. Housing retrofit projects renew at least the building envelope and the domestic installations to extend the technical dwelling life with 40 years. Renovation projects track a maintenance schedule to exchange parts of a dwelling during various moments in the lifespan to extend the technical dwelling life with 25 years after interference. The adoption of innovative housing retrofit concepts influences the social economic housing association environment. Rogers describes how an organization decides to adopt an innovative product, called as the innovation adoption- and diffusion process. Rogers (2003, p. 5) defines diffusion as: the process in which an innovation is communicated through certain channels over time among the members of a social system”. The innovation adoption decision process includes five phases: Knowledge, Persuasion, Decision, Implementation and Confirmation. The process contains three categories with factors that influence the adoption of a housing retrofit concept: 1. Policy and housing stock conditions constitute the technological regime and dominant design; 2. Characteristics of the housing association, the project organization and their employees; 3. Characteristics of the concept: advantage, compatibility, complexity, trialability and observability;
