Self-building courses have been identified as a stimulus for user innovations, local embedding and diffusion of renewable energy technology. In this paper we explore the Finnish solar heat collector self-building courses. Our empirical material consists of field observations, interviews with teachers and a survey of participants since the early activities in late 1990s. Our findings show that course participants have started to follow energy discussions, collect information and actively advise others. Participants view themselves as increasing capable actors in renewable energy. They have also begun to engage in energy saving and renewable energy at home on a wide front. The fact that only 41% have installed their collector points to the importance of timing but also to the way in which self-building courses serve as a first step into renewable energy. Overall our results indicate that self-building courses offer possibilities for material engagement that has outcomes beyond the immediate objectives of the course.

During the average fifty or sixty years of building lifecycles, large amounts of energies are consumed at all stages, from the production of building materials, transportation for project constructions, daily use, and maintenance to demolition, in particular, the daily energy consumption of air-conditioners, lighting, and elevators. The main “energy saving indicator,” from among nine green building indicators, evaluates the electrical power consumption of air conditioners and lighting. The main evaluation items are building envelope heating load ratio, air-conditioner energy efficiency ratio, and lighting energy saving ratio. During evaluation, the promotion and application of renewable energy is encouraged by incentive factors. The development and use of renewable energy technology may improve energy utilization efficiency, maintain a balance of supply and demand, and reduce environmental pollution, thus, this study developed a indoor personal office system with 1KW solar energy and a 500W proton exchange membrane fuel cell (PEM fuel cell) as the power source, which is composed of LED indoor lighting, air fan, LED table lamp, notebook computer, printer, and acoustic equipment. Under continuous operations of 24h, this office system will generate 12kwh of electricity, which reduces 7.656kg of carbon dioxide output. If continuously operated for 1 year, it will generate 4,320kwh electricity, which reduces 2,756.16kg of carbon dioxide output. In addition, the side product water can be recycled as landscape water.
