Solar Heating Systems in Renewable-based District Heating

AbstractIn this study, we explored cost-optimal renewable-based district heat production systems and potentials to integrate solar heating systems in such systems under different contexts. We investigated under what conditions a solar heating system become cost-efficient to integrate in district heat production systems and the consequences of this integration. We considered a small-scale district heat production system in the south of Sweden where district-heat production cost is higher and hence it is more cost efficient to integrate solar heating in such a district heat production systems. The cost-efficiency of integrating solar heating in a minimum-cost renewable-based district heat production system depends on future fuel prices and investment costs of solar heating systems. In any case, integrating solar heating will help to reduce the use of other primary energy resources as biomass

Understanding Online Channel Expansion in an SME Context: A Business Model Perspective

The purpose of the paper is to study, from a business model perspective, value creating activities taken by SMEs when making a transition to an online multichannel context by adopting and adding e-commerce and/or m-commerce. 16 SMEs in Sweden are studied using a basic qualitative research approach and an e-transit business model configuration. Main results of the study are the existence of primary and secondary transition activities and the existence of a discrepancy between actions taken and their perceived degree of importance. One main conclusion is that the combination of value creating activities an SME should focus on during different stages of an online channel expansion differ depending on transition category and will change over time
