Abstract [en]

The endeavour to align the goals of the Swedish food strategy with the national environmental quality objectives and the 17 global SDGs, presents an extraordinary challenge that calls forsystemic innovation. Industrial symbiosis can potentially provide the means for increasing sustainable food production, using locally subexploited resources that can reduce the need for land, agro-chemicals, transport and energy. This case study of the municipality of Härnösand, aims to assess opportunities and challenges for using waste flows and by-products for local food production, facilitated by industrial symbiosis. A potential symbiotic network was developed during three workshops with the main stakeholders in Härnösand. The potential of the COVID-19 pandemic to instigate policy changes, behavioural changes and formation of new alliances that may catalyse the transition towards food systems based on industrial symbiosis is discussed. The material flow inventory revealed that many under exploited resource flows were present in quantities that rendered them commercially interesting. Resources that can be used for innovative food production include, e.g., lignocellulosic residues, rock dust, and food processing waste. The internalised drive among local companies interested in industrial symbiosis and the emerging symbiotic relations, provide a fertile ground for the establishment of a local network that can process the subexploited material flows. Although there are multiple challenges for an industrial symbiosis network to form in Härnösand, this study shows that there is a significant potential to create added value from the region’s many resources while at the same time making the food system more sustainable and resilient, by expanding industrial symbiosis practices.

Abstract [en]

This research presents a solution for collecting indoor environmental sensor values and how the gathered sensor values then could be used for green building certification and in turn also machine learning based smart building control. We have created and implemented a proof of concept system consisting of a sensor collecting device using off the shelf hardware to complement the existing sensor information from buildings, as well as a cloud system for persistently storing this data for later usage. We have measured and evaluated our implemented system for our envisioned scenarios. In which we could observe that our proof-of-concept could scale to handle almost four sensor value updates per second at maximum stress, as well as having a latency for uploading a sensor value from our sensor of about 130 ms. Finally, we present our future and ongoing work based on these results which outlines our work for smart building control, green building certification, and the energy signature of buildings.

Abstract [sv]

Dålig inomhusmiljö i grundskolor i Sverige verkar vara ett problem i många kommuner. I det här projektet har man tittat på om en installation av en stor mängd växter i ett klassrum skulle kunna ändra på det. Det finns nämligen forskning om visar att vi mår, både fysiskt och psykiskt, bättre om vi är omgivna av växter. Fysiskt för att de kan rena luften och omvandla koldioxiden till syre. Dessutom ökar de luftfuktigheten och reglerar temperaturen. Psykiskt kanske för att vi är en del av naturen och har levt i den största delen av mänsklighetens historia. Växter kan också skapa bättre akustik i rummet genom att absorbera ljudvågor. Dessutom finns det tidigare studier som visar att växterna kan öka både koncentrationsförmågan och minnet.Projektet hade tre olika perspektiv; design, miljö och hälsa. Platsen för projektet var en grundskola belägen i ett mindre landsbygdssamhälle i norra delarna av Sverige. Totalt installerades 350 gröna växter i fyra växtställningar, dessa fördelades sedan på två olika klassrum med ca 25 elever ur årskurs 8 vardera. Ett liknande klassrum (åk9) bredvid dessa användes som referensobjekt. Växtställningarna designades av industridesignstudenter på Mittuniversitetet och skulle resultera i fungerande prototyper med automatisk bevattning. Projektet pågick under två terminer, höstterminen 2019 och vårterminen 2020.Mätningar av inomhustemperaturen visade att de gröna växterna bidrar till en mer stabil temperatur och till och med kan öka temperaturen något, vilket kan användas för att minska värmebehovet. Effekterna på luftfuktighet var endast högre i klassrummen med växter under natten när ventilationsflödet var lågt. Koldioxidnivåerna i klassrummen med växterna var 10 % lägre under undervisningstiden jämfört med kontrollklassrummet vilket indikerar att gröna växter skulle kunna användas för att minska ventilationsluftflödet och därigenom minska värmeenergiförluster. Energiberäkningen visade upp till 18% minskning på uppvärmningsbehovet. Mängden luftburna partiklar var redan låg och man kunde inte se någon förändring efter installationen av växterna.I början uppskattade både lärare och elever att de hade fått ett “grönt klassrum”. Minnet och koncentrationsförmågan hos eleverna blev bättre. I mätningen ett halvår senare hade dock effekten avtagit. Det är svårt att säga om detta berodde på hemmablindhet, Covid 19-pandemin (som hade brutit ut en månad tidigare) eller för att det var problem med några av bevattningssystemen som gjorde att vissa växter vissnade. Kanske en kombination.Resultaten av det här projektet kan ge kunskap och inspiration till kommuner och skolor om hur de kan förbättra inomhusklimatet med växter som ett kostnadseffektivt komplement till befintliga ventilationssystem som också kan förbättra elevernas och lärarnas prestationer och välbefinnande. Det är värt att notera att den här studien genomfördes på landsbygden där det redan är en bra luftkvalitet. Därför vore intressant att genomföra en liknande studie i ett storstadsområde men sämre luftkvalitet och även i andra med typer av byggnader med lägre ventilationsflöde.Det är också värt att notera att när projektet befanns sig i halvtid inträffade en pandemi, covid-19, som gav en betydande påverkan på både många samhällsfunktioner och för många människor. Detta kan ha påverkat resultatet av effekterna i mätningarna av hälsa och koncentration.

Abstract [en]

Many municipalities in Sweden seems to have a problem with indoor environment in primary schools. In this project, we have looked at whether an installation of a large number of plants in classrooms could change that. Previous research has found that humans feel both physically and mentally better if we are surrounded by plants. Physically, because they can purify the air and convert carbon dioxide to oxygen. In addition, they increase the humidity and regulate the temperature. Mentally, perhaps because we are part of nature and have lived in it most of human history. They also create better acoustics in the room by absorption of sound waves. In addition, some previous studies show that plants can increase both the ability to concentrate and memory.The project had three different perspectives; design, environment and health. The site for the project was an elementary school located in a small rural community in the northern part of Sweden. A total of 350 green plants were installed in four plant stands distributed in 2 different classrooms with about 25 students in grade 8 in each room. A similar classroom (grade 9) next to these was used as a reference object. The plant stands were designed by industrial design students at Mid Sweden University and would result in functional prototypes with automatic irrigation. The project lasted for two semesters, the autumn semester 2019 and the spring semester 2020.Measurements of the indoor temperature showed that the green plants contribute to a more stable temperature and can even increase the temperature slightly, which can be used to reduce the need for heat. The effects on humidity were only higher in the classrooms with plants during the night when the ventilation flow was low. The carbon dioxide levels in the classrooms with the plants were 10% lower during the teaching time compared to the control classroom, which indicates that green plants could be used to reduce the ventilation airflow and thereby reduce heat energy losses. Energy modelling showed a reduction of up to 18% in heating demand. The amount of airborne particles was already low and no change could be seen after the installation of the plants.In the beginning, both teachers and students appreciated that they had been given a "green classroom". The students' memory and ability to concentrate improved. In the survey six months later, however, the effect had diminished. It is difficult to say whether this was due to home blindness, the Covid 19 pandemic (which had broken out a month earlier) or because there was a problem with some of the irrigation systems that caused some plants to wither.The results of this project can provide knowledge and inspiration to municipalities and schools on how they can improve the indoor climate with plants as a cost-effective complement to existing ventilation systems that can also improve students' and teachers' performance and well-being. It is worth noting that this study was conducted in a rural area where there is already a good air quality. Therefore, it would be interesting to carry out a similar study in a metropolitan area with poorer air quality and also in other types of buildings with lower ventilation flow.It is also worth noting that when the project was at half-time, a pandemic, covid-19, occurred which had a significant impact on both many societal functions and for many people. This may have affected the results of the effects in the measurements of health and concentration.

Abstract [en]

Poor indoor environment in primary schools in Sweden seems to be a problem in many municipalities in Sweden. In a report from the Swedish Public Health Agency, it is estimated that 40 percent of schools have complaints about air quality. The causes of the problems are poor ventilation, high humidity, changes that where made to the buildings, and high density of pupils in the classrooms. Improving indoor air by improvement of ventilation systems can be too costly for municipalities. In this project, we have looked at whether an installation of a large number of green plants in classrooms could change that, and even reduce energy use. There is research that shows that we feel both physically and mentally better if we are surrounded by green plants. Physically, because they can purify the air and convert carbon dioxide to oxygen. In addition, they increase the humidity and regulate the temperature. Mentally, perhaps because we are part of nature and have lived in it most of human history. The case study in this project was an elementary school located in a small rural community in the northern part of Sweden. A total of 350 green plants were installed in four plant‐stands distributed in 2 different eighth grade  classrooms with about 25 students in each. A similar adjacent classroom (ninth grade) was used as a reference object without green plants. The plant‐stands were designed by industrial design students at Mid Sweden University and would result in functional prototypes with automatic irrigation. The project lasted for two semesters, the autumn semester 2019 and the spring semester 2020. Measurements of the indoor temperature showed that the green plants contribute to a more stable temperature and can even increase the temperature slightly, which can be used to reduce the need for heat. The effects on humidity were only higher in the classrooms with plants during the night when the ventilation flow was low. The carbon dioxide levels in the classrooms with the plants were 10% lower during education time compared to the control classroom, which indicates that green plants could be used to reduce the ventilation air flow and thereby reduce heat losses from exhaust air flow. The amount of airborne particles was already low and no change could be observed after the installation of the plants.

Abstract [en]

The sustainable building engineering education at Mid Sweden University has since it started 1994 a strong focus on sustainable building. It is also committed to be a pilot case for blended learning. All courses in the building engineering program were from the autumn 2012 adapted to a blended learning concept. That means that all courses are available in an integrated mix of ordinary campus and online distance education in real time. Blended learning is a way of taking in account different needs concerning student study situation. Adult students, bound with house and families, often prefer more distance education while younger students need more campus education. The results of the case study show that blended learning attracts more students, and allows students with different backgrounds to study and gives a more solid base of students for the program. It also allows a more flexible way of allocating resources by integrating two previous modes of delivery for the same program. This provides an education with a well thought through quality assurance. Another strength of blended learning is the possibility to connect individual students to a larger collective of students, making it possible for them to relate to and learn with and from others by social interactions that are difficult to achieve in solely online education. The pilot case is so far limited to the sustainable building engineering program but in a next stage the concept is planned to be spread to other engineering programs and other education programs at Mid Sweden University.

Abstract [en]

The design concept of conditioned atria receive growing popularity in  both commercial and service buildings all over the world, but still not common in the residential sector. This study used a psychological framework to examine if building design with enclosed heated atria in apartment buildings can enhance sense of community and social interactions in Nordic climates. A qualitative study was conducted to understand the perception of residents living in apartment buildings with heated atrium. One of the few examples in Sweden. This was compared to the experience of residents in a “traditional” apartment building without an atrium. The questionnaire was comprised of six parts: (i) socio-demographic aspects; (ii) information about the apartment; (iii) social activities within the building; (iv) social interaction with neighbours; (v) information about principles in life; and (vi) sense of community linked to their homes.

The results showed significant social differences between the residents of the atrium and “traditional” buildings, which could not be explained solely by differences in preferences and principles in life. A large proportion of the social differences between the buildings could be explained by the building design, as the common and semi-private areas within the atrium building provide opportunities to establish social interactions. The residents in the atrium building was found to have greater sense of community and higher frequency of interactions, which are both parts of social sustainability.

Abstract [en]

Environment problems are complex and require a system integrated approach, which involves different time scales and spatial resolution. Yet, many parts of the world are facing similar environmental challenges. Therefore, mankind needs to share knowledge and work together across physical borders, language barriers, and cultures differences.

In our International Master's programme in Ecotechnology and Sustainable Development in Mid-Sweden University, we use new pedagogical technologies to bring students from different nations and cultures together and reinforce teamwork. All courses in the program are in English and students can choose to be present in the classroom or to stream lectures online in real-time. Via special software, teachers are able to communicate both with classroom and distance students simultaneously. This provides flexibility to access graduate level courses in environmental science from anywhere in the world.

Still, we aim to unify the students as one group. To achieve that, all students are invited to a joint activity in a mountain area nearby the university for one week. There, they are performing different field measurements, which help them to know each other and develop a group feeling. Group assignments are red thread throughout the program. It enhances student communication and exchange of information from different parts of the world.

The overall aim of the master programme is to “lift” the students 10.000 meter up above ground. From that height they can see forests, water systems, cities and societies and not individual trees, streams, buildings or people. Only then they can understand how environmental issues are related and could be analyzed. This is achieved by introducing a variety of advanced system modelling tools, policy instruments, impact strategies, and communication skills. After graduation, the students are able to assist policy makers to resolve a variety of integrated environmental issues with ecological, social, cultural and economic perspectives.
