Modification of ZEB Lab (NTNU) building design - prioritizing passive climate control & comparison with existing
No full textSustainability is one of the fast-developing trends in every aspect of our lives, each year demand and goals for making less pollution of the environment is increasing. Thus, buildings as one of the highest pollutants must be not only, reconsidered as a way of construction materials and energy consumption, but also kept up with the stricter sustainable standards which appears each year, to reach the highest ZEB (Zero Emission Building) goals.
Study will include redesign of existing ZEB building, which is located in NTNU Gløshaugen campus in Trondheim. A ZEB Laboratory is an experimental facility, it plays role as a testing place of new technologies on a larger scale. The ambitions of that building is to achieve ZEB–COM level in 60 years perspective.
This thesis aims to unveil new possibilities of passive strategies together with finding better combinations with active ones to decrease building’s energy consumption, with keeping or improving indoor comfort. Main goal is to reach the ZEB-COM level with using same amount of material or less, with the same area of the building, and implementation of new or improving existing passive strategies. There will be simulations of different possible modifications of form of ZEB Laboratory, with their pros and cons in comparison with existing one, to find the best possible shape in terms of energy consumption and PV production.
In the end there will be two proposed shapes in comparison with existing one. First form is called “Big North” will have lesser energy consumption and similar PV production as the existing one, with the ZEB Balance calculation of (-0,22) in comparison with existing (-0,17), both reached ZEB-COM level. Then the second form “Small North” will have even lower energy consumption due to the shape, however much smaller PV production, which will lead to not reaching ZEB-COM (0,66).
At the level of a ZEB-COM building it is difficult to introduce changes which would make a significant difference. As one can see from the results, the improvements are small in relation to the existing ZEB lab, but it is possible to make improvements with replanning of windows placements, reducing of material usage and modifying passive strategies. My research shows that one can achieve some improvements by prioritizing passive strategies in the context of finding a balance between passive and active strategies
Redevelopment of Skotfossbruk into an energy efficient neighbourhood considering the principles of circularity and energy exchange
No full textSkotfossbruk, en gang den største papirfabrikken i Nord-Europa og som har distribuert papirprodukter globalt, måtte stenge etter mer enn 70 år med vellykket drift. Startet i år 1892 pleide det å produsere en rekke produkter som innpakningspapir til avispapir for New York Times. Den nybygde Telemarkskanalen, sett på som verdens åttende underverk av europeere som ligger i nærheten av bruket, hentet inn råvarer fra den nærliggende Telemarksskogen og fungerte som en viktig rute for transport av mennesker, varer og husdyr. Det ligger i Skien kommune ved innsjøen Norsjø som etter byggingen av et vannkraftverk gjorde at industrien satt over sin kraftkilde. Et sviktende marked betydde nedleggelse av industrien med de siste produktene som ble avsluttet i 1986. I dag er industrien en del av en kultursti som forteller historier om den strålende fortiden. Denne artikkelen tar sikte på å omutvikle papirfabrikken til et nabolag som kan tiltrekke seg mennesker fra hele verden. Ved å redesigne restene av den gamle industrien for å foreslå nye bygninger, kan den bringe lokalsamfunn sammen og fremme ideen om en bærekraftig ombygging. Fremme gangbar infrastruktur og forbedre de romlige kvalitetene gir det rom for ulike aktiviteter. Nabolaget oppnår på å bli et netto nullenerginabolag gjennom lokal produksjon av energi gjennom fornybar energi. Siden det vil komme lite vannkraft i Norge i fremtiden, er det viktig å demonstrere selvforsyning i slike prosjekter som kan bli en prøveplass for andre nabolagsprosjekter. Sirkularitet i matsystemet har vært en kritisk del av dette nabolaget, siden det genererer en viss mengde energi for å dekke energibehovet. Lokalisering av matproduksjon i dette nabolaget betydde også at folk er klar over maten de konsumerer, og bygger bro mellom produksjon og forsyning. Nabolaget demonstrerte intern energiutveksling for å oppfylle energibehovet til bygningen først og deretter utveksle overskuddsenergien utenfor nabolaget. Gjennom nøye utforming og valg av riktige byggesystemer var nabolaget i stand til å redusere den totale energibelastningen og gjennom egenproduksjon var det i stand til å dekke energibehovet, noe som demonstrerte en vellykket utvikling av prosjektet.Skotfossbruk, once the largest paper mill in North Europe and having distributed paper products globally had to close after more than 70 years of successful operation. Started in the year 1892 it used to manufacture a variety of products such as wrapping paper to newsprint for the New York Times. The newly constructed Telemark Canal, regarded as the 8th wonder of the world by Europeans located near the mill brought in raw materials from the nearby Telemark Forest and served as an important route for transporting people, goods, and farm animals. It is situated in Skien municipality next to lake Norsjø which after the construction of a hydroelectric power plant meant the industry was sitting over its power source. A failing market meant the closure of the industry with the last produce ending in 1986. Today the industry is part of a cultural trail that tells stories about the glorious past. This paper aims at redeveloping the paper mill to a neighbourhood that can attract people from all over the world. By redesigning remains of the old industry to proposing new buildings it can brings communities together and promote the idea of a sustainable redevelopment. Promoting walkable infrastructure and improving the spatial qualities it provides a space for various activities. The neighbourhood achieves on becoming a net zero energy neighbourhood through local production of energy through renewables. Since little hydropower will be coming in Norway in the future, it is important to demonstrate self-sufficiency in projects of this nature that can become a testing ground for other neighbourhood projects. Circularity in the food system has been a critical part of this neighbourhood, as it generates a certain amount of energy to fulfil the energy demand. Localisation of food production in this neighbourhood also meant that people are aware of the food they are consuming bridging the gap between production and supply. The neighbourhood demonstrated internal energy exchange to fulfil the energy demand of its building first and then exchanging the surplus energy outside the neighbourhood. Through careful designing and selection of right building systems the neighbourhood was able to reduce the overall energy load and through self-production it was able to cover its energy needs demonstrating a successful development of the project

Symbiotic Rooftop Green Structures and its application at Saupstad center
No full textMed skiftende klima og progressiv miljøforringelse får urbant landbruk (UA) betydning som en naturbasert løsning for bærekraftige byer. Den fremmer ny forretningsmodell for bønder, innbyggerengasjement, miljømessige og sosiale fordeler, ny urban estetikk, og fungerer som et pedagogisk verktøy. På bakgrunn av dette er Saupstadsenteret i Trondheim identifisert som et potensielt område for utforskning av et takdrivhus (RTG) som en del av Trondheim Kommunes områdeutviklingsprogram. Det eksisterende bygget er omprogrammert til et samfunnshus med mathall, felleskjøkken, bakeri og butikklokaler for å jobbe symbiotisk med drivhuset. Som en del av denne oppgaven er det utført analyser av RTGs konvolutt, avlinger dyrket og deres innvirkning på energibelastninger. Ved overordnet analyse av bygget integrert med RTG er det observert at netto varmebelastning og kjølelast avtar. RTG fungerer som en termisk buffer ovenfra, og reduserer dermed varmetapet fra bygningen under. De strukturelle sjaktene muliggjør restvarmestrømmen fra kjøkken og bakeri til drivhuset for dets varmebehov. Den bruker også CO2 fra brukerne i bygningen for å hjelpe til med dyrkingen av avlinger. Denne symbiotiske syklusen utforskes i denne oppgaven for å forstå energibesparelsene og de arkitektoniske implikasjonene på bygnings- og nabolagsnivå. Følgelig viser denne oppgaven potensialet ved å integrere takdrivhus i utformingen av et lokalt matrom.With changing climate and progressive environmental degradation, urban agriculture (UA) is gaining importance as a nature-based solution for sustainable cities. It promotes new business model for farmers, citizen engagement, environmental and social benefits, new urban aesthetic, and acts as an educational tool. Given this, the Saupstad center at Trondheim is identified as a potential site for exploring a rooftop greenhouse (RTG) as a part of Trondheim Kommune’s area development programme. The existing building is reprogrammed as a community center with food hall, community kitchen, bakery, and retail facilities to work symbiotically with the greenhouse.
As a part of this thesis, analysis has been done on RTG’s envelope, crops grown and their impact on energy loads is performed. On overall analysis of the building integrated with RTG, it is observed that the net heating load and cooling load decreases. The RTG acts as a thermal buffer from above, thereby reducing heat losses from the building below. The structural shafts enable the residual heat flow from kitchen and bakery to the greenhouse for its heating requirements. It also uses the CO2 from the users in the building to aid the growing of crops. This symbiotic cycle is explored in this thesis to understand the energy savings and architectural implications at building and neighbourhood level. Consequently, this thesis showcases the potential of integrating rooftop greenhouses in the design of a community food space
Redesign of ZEB Lab building, NTNU - prioritising passive climate control & comparison with existing
No full textGreenhouse gas emissions are by far the most critical concern of our era, and the building and construction sector plays a significant role in this regard. SINTEF and the Norwegian University of Science and Technology (NTNU) have been working on this matter for a long time, and they just obtained an entirely new arena for investigating and testing innovative solutions in real life which is well known as “ZEB Laboratory”. The ZEB Laboratory is possibly the only one of its kind to obtain the environmental goal of ZEB-COM with the support of active strategies and passive strategies in the design. It is important to noticed that the active solutions were the main focus points and even surpass the passive solutions in this building design’s strategies. According to that matter, therefore this thesis aims to re-develop an alternative design of ZEB Laboratory building with the goal of reaching the same environmental goal (ZEB-COM) as close as possible with passive control strategies being the foremost priority in design yet without excluding mechanical strategies based on the identical user brief, function, location, site boundary, regulation, construction material, energy efficiency strategies and energy supplies; but with a slight difference in building’s footprint.
The methodologies for this study include a literature review on the original ZEB Laboratory building and its strategies used as well as passive strategies to achieve ZEB-COM; architectural and environmental analysis of original building and the new alternative design; computerized simulations; LCA and ZEB Balance calculation with limitation for evaluation and verification of the setup goal.
By a foremost prioritized of passive strategies of maximizing solar heat gain with optimal orientation, optimal building form, optimal building envelope design and maximization of daylight condition, the total annual energy consumption of the building in the operational stage dramatically decreases compare to the existing building due to the lower energy demand for room heating and lighting in the building. With the supportive of the active strategies such as PV production and energy efficiency strategies and supplier, the new alternative ZEB building could possibly reach the ZEB-COM goal with the lower value of ZEB balance comparing to the original building.
These results of this alternative design with the main focus point of passive solar heat gain would suggest that in order to reach the ZEB-COM level, the building does need to focus both the passive and active strategies, for example, design with solar heat adpative form and maximize the PV production by having the optimal slanted roof. However, it is essential to prioritize and passively minimize the total energy consumption in the building in the initial phase. Then, the active strategies will play an important role in the remained energy consumption
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
