“…The daily potential is variable depending on the season, from about 0.55 kWh in January to 5.8 kWh in June [140]. Nowadays, the potential of solar heat energy generation in Lithuania reaches 1.5 TWh/year [140] and, up until 2016, about 14800 m 2 of solar collectors were installed in the country, while the application refers mainly to a single-family houses [141].…”

The purpose of this review is to provide insight and a comparison of the current status of district heating (DH) systems for selected Baltic Sea countries (Denmark, Germany, Finland, Latvia, Lithuania, Poland, and Sweden), especially from viewpoints of application and solutions of novel smart asset management (SAM) approaches. Furthermore, this paper considers European projects ongoing from 2016, involving participants from the Baltic Sea Region, concerning various aspects of DH systems. The review presents the energy sources with particular attention to renewable energy sources (RES), district heating generations, and the exploitation problems of DH systems. The essential point is a comparison of traditional maintenance systems versus SAM solutions for optimal design, operating conditions, and controlling of the DH networks. The main conclusions regarding DH systems in Baltic Sea countries are commitment towards a transition to 4th generation DH, raising the quality and efficiency of heat supply systems, and simultaneously minimizing the costs. The overall trends show that applied technologies aim to increase the share of renewable energy sources and reduce greenhouse gas emissions. Furthermore, examples presented in this review underline the importance of the implementation of a smart asset management concept to modern DH systems.

“…It is also mentioned that when land area is available it is 25-60% cheaper to install a horizontal than a vertical heat exchanger. Reference [37] mentioned that 17 projects combining solar thermal systems and heat pumps have been implemented in Lithuanian hospital buildings. Three Northland hospitals that have replaced the old fossil fuel central boiler system with heat pumps providing heat and hot water with payback time at around 2 years have been reported, TRANSPOWER, 2019.…”

Hospitals consume large amounts of energy in their daily operations. The necessity to comply with the global targets for climate change mitigation requires the decrease in their energy and fossil fuels consumption as well as reduction of their CO2 emissions. The aims of the current work are to study the possibilities of using several clean and low carbon emission technologies for heat, cooling and electricity generation in hospitals. The use of solar-PV panels, CHP systems and heat pumps has been examined as well as the possibility of financing these environmentally friendly energy technologies with external funding. Our results indicate that the abovementioned sustainable energy technologies are mature, reliable and cost-efficient providing heat, cooling and electricity in hospitals having also positive economic, social and environmental impacts. Their combined use with other low or zero carbon emission technologies could help in the transformation of hospital buildings to nearly zero energy buildings minimizing or zeroing their carbon footprint due to energy use. Various financial tools have been developed so far utilizing mainly private funds for financing clean energy investments in hospitals with external resources. Present work is important since it indicates that the previously mentioned sustainable energy technologies can be used in hospitals assisting in their transformation to low carbon emission organizations since in coming decades the mitigation of climate change in our societies will be necessary and crucial.

“…Several studies were also implemented, with the aim to improve the design of solar thermal collectors through the adoption of more environmentally friendly practices [25,26]. The penetration of solar thermal technologies into northern European countries, where their contribution to the energy mixes is still limited, is also another topic of scientific interest [27,28].…”

Inevitably, the 21st century has initiated a series of developments in the construction industry, leading to its digitalization and resulting in a series of innovative approaches and practices. At the same time, the construction industry, being one of the main global environment polluters, should fulfil well-established, as well as novel, sustainability requirements in order to evolve in harmony with the rising concerns on the availability of natural resources. This overview study aims to present the main developments, research, and scientific challenges in the field of sustainable construction, emphasizing the field of energy. The study aims to present a state-of-the-art scientific discussion on the sustainable built environment topic by analyzing cutting edge topics in the fields of building elements and whole building energy assessment, of indoor air quality and low carbon buildings, as well as on sustainable energy systems and smart buildings. The study also presents the state-of-the-art in existing tools which are adopted for the assessment of the sustainable built environment, including the use of digital tools and building information modelling for the energy assessment of the built environment, as well as the application of Life Cycle Assessment on building-related processes. Cross cutting issues related to the analysis of the building sector in the Industry 4.0 era, such as sustainability management topics and environmental geomatics are also discussed. The study concludes in those fields which will be of interest of the scientific community in the following years, towards achieving the goals of the sustainable development of the building sector.
