This paper presents a comprehensive analysis of public procurement documents in the domain of university buildings taken from the e-procurement platform, particularly focusing on their transformation towards more efficient energy consumption. Using a corpus of the titles of the public procurement documents from 2020 to 2022, we used Latent Dirichlet Allocation (LDA) for topic modeling to understand the key thematic areas of focus. The methodology presented in this study incorporated a bifurcated approach. This two-stage procedure began with preprocessing and dictionary creation from the corpus of titles of procurement documents. Following this, the Latent Dirichlet Allocation (LDA) model was employed for topic extraction and trend analysis, thereby providing a comprehensive understanding of the thematic progression in procurement practices over time. Our analysis revealed a shift in emphasis from modernization towards the adoption of energy-saving technologies as well as a growing focus on broader sustainability initiatives. However, a less prevalent topic was adherence to cooling & heating systems, suggesting potential areas for improvement in procurement practices. These findings contribute to the growing body of knowledge on sustainable procurement in university buildings and offer valuable insight for universities to enhance their energy efficiency strategies.

Cross-border innovation clusters are some of the essential concepts of reinforcing regional innovation capacities. In accordance with the concept of Industrie 4.0, introduced in 2011 in the Hannower Messe as the next industrial revolution, there appear new opportunities to build innovation clusters, combining innovation with a networked manufacturing system. Its core property will be new network technology on which they would create new products and services. This new type of cross-border innovation clusters will be the result from innovation policies carried out in regions. The main advantage of this type of clusters is that they allow the re-industrialization of regions, the end of mass production monopoly, and, thus, a successful competition with corporations, and also prosumerbased production. To achieve these objectives, the cluster has to deal with economically efficient technology. One of the key instruments of innovation policy will be the evaluation of the economic potential of the cluster before its appointment.The aim of the article is twofold. Firstly, it is to introduce the idea of a cross border innovation cluster and a network that combines innovation with a network manufacturing system. Secondly, the goal is to provide the method for assessing the economic potential of a prospective cross border innovation cluster. The assessment of cluster's economic potential, based on the evaluation of the technology used in its development and the future products and services, developed in the prospect cluster, will be among the most important tools of innovation policy in regions. This issue is important because the methodology of such an economic potential assessment of prospect cross-border innovation clusters has never been developed.In this study, the authors have collected representative examples of the implemented Industrie 4.0 solutions. Using a QuickLook assessment methodology, developed at the University of Texas, USA, and transferred to the University of Lodz, Poland, as a part of the offset program established in 2003, the authors have found that it could be applied to both Cyber-Physical System based Industrie 4.0 initiatives and other network manufacturing initiatives, based on the new technology. On the basis of a case study, concerning Polish cluster initiative Green Cars, the article concludes that there are many potential applications of the presented methodology to the Lithuanian-Polish prospect manufacturing system.
