Factors affecting the production and reproduction performance of tropically adapted beef cattle in southern AfricaTaylor, Glen James 04 August 2008 (has links)
In the first study, non-genetic influences on pre- and post-weaning growth traits of a tropically adapted beef breed in the arid sub-tropical environment of Southern Africa were investigated. Production data of Santa Gertrudis cattle for a ten-year period were analysed. The herds were managed extensively under harsh arid environmental conditions in the northern thornveld region of Namibia. The cattle were divided into summer and winter breeding seasons, which were limited to 90 days for each group. The effect of sex, herd, season, calf birth year and cow parity group on birth weight, pre-weaning average daily gain, weaning weight, yearling weight, eighteen month weight and post-weaning growth rate were analysed. Sex was a highly significant (p < 0.001) source of variation for birth weight, weaning weight, 12 month weight, 18 month weight and significantly influenced (p < 0.05) pre and post-weaning weight gain. Bull calves were 3.05, 13.75, 123.37 and 238.99 kg heavier than the heifer calves at birth, weaning, yearling and eighteen months respectively and grew faster by 0.07 kg/day from birth to weaning and 0.65 kg/day from weaning to 12 months of age. The effect of season on birth weight, weaning weight, 18-month weight and pre-weaning growth rate was highly significant (p < 0.001). Calves born in the summer season had a lower birth weight compared to calves born in the winter season. However, the summer season calves were heavier by 17.67 kg at weaning but only by 1.7 kg at 12 months of age. They grew faster by 0.16 kg/day from birth to weaning. Calf birth year significantly influenced (p < 0.001) all traits measured with no fixed trend over time for the traits. Herd effects were highly significant (p < 0.001) for birth weight and 12-month weights and significantly influenced (p < 0.05) weaning weight, 18-month weight and growth rate from weaning to 12 months of age. The effect of cow parity was not significant on birth weight, 12-month weights, 18-month weights and post-weaning growth rates, but was significant (p < 0.05) for weaning weight and pre-weaning growth rates. Sex, herd, season of calving, calf birth year and herd x season x calf birth year significantly influenced growth traits and should be taken into consideration when evaluating the genetic merit of cattle during selection. The second study was conducted to determine the associations between lifetime cow fertility and cow frame size, also between lifetime cow fertility and pre-weaning as well as post-weaning calf growth in tropically adapted Santa Gertrudis cattle. A total of 2 506 Santa Gertrudis cows were divided according to their average lifetime calving interval (CI) into short calving interval (SCI, < 400 days, n = 914 cows) and long calving interval (LCI, > 400 days, n = 1 592 cows) groups. Calves were weighed at weaning at approximately 7 months of age. Hip height of cows and pre-weaning gain of calves of the SCI cows (135 cm and 1.01 kg/day) were significantly (p < 0.05) lower than those of the LCI cows (141 cm and 1.25 kg/day). Calves from SCI cows were born significantly earlier in the calving season than calves from LCI cows as measured by age at weaning (221 versus 189 days). As a result of compensatory growth there was no significant difference for yearling weight between progeny of SCI and LCI cows (348 kg versus 349 kg). It is concluded that SCI cows are smaller in size, with significantly lighter calves at weaning. A negative correlation exists between fertility and pre-weaning calf growth. High post-weaning calf growth is compatible with high cow fertility. In the third study, the effects of heifer frame size (FS) on their subsequent performance and the pre-weaning growth of their calves were evaluated using records collected from 1989 to 1998 from the Waterburg Estates at Otjiwarongo, Namibia. Based on hip height at 18 months of age, heifers were assigned to three different frame size (FS) groups: small (< 124 cm), medium (125 to 135 cm), or large (>136 cm). Calving rate (CR), calving date (CD), calf survival rate (CSR), reproductive efficiency (SANDEX), weaning rate (WR), birth weight (BW), weaning weight (WWT), pre-weaning ADG (P-ADG), and kilograms of calf produced per cow bred (KCB) were collected from first –(n = 830), second (n = 623) and third and greater-parity (n = 571) cows. Frame size of heifers significantly influenced (p < 0.001) their calving rate as second-parity cows with small and medium FS cows having higher CR than large FS cows. In spite of heavy culling of cows that had large FS as heifers, calving rates of second parity cows in this category were 41% less than that of second parity cows that had small and medium FS as heifers. In third or greater-parity cows, CR was greater (p < 0.05) for small FS than for medium and large FS. CSR was similar for heifers with a small, medium and large FS for the first, second and third and greater parity groups. Weaning rates of large FS (34.2 ± 11.27), second-parity cows were less (p < 0.001) than those of small (82.9 ± 5.58) and medium (79.0 ± 4.67) FS animals. Among all parity groups, BW of calves born to large FS were significantly higher (p < 0.05) than those of small and medium FS cows. Calves weaned by small FS animals as first parity cows, had lower (p < 0.05) WWT than those weaned by medium and larger FS, but large FS weaned heavier calves (p < 0.05) than small and medium FS in the third and greater-parity group. In first parity cows, calves of large FS had greater P-ADG (p < 0.05) than those from small FS, but in second parity cows the calves from medium FS (p < 0.05) out performed those of small and large FS, while calves from third and greater parity cows of medium and larger FS had greater (p < 0.05) P-ADG than cows with a small FS. Male calves were heavier (p < 0.05) at birth, at weaning and grew faster (P-ADG) than their female counterparts. KCB was similar among small and medium FS cows, but both tended to be greater (p < 0.05) than KCB of large FS cows and as second parity cows the small and medium FS cows had an even greater (p < 0.001) advantage over the large FS animals. Small and medium FS females calved earlier, and had greater calving rates and weaning rates, as well as greater kilogram of calf produced per cow exposed than the large FS females. The performance (fertility and the growth performance of their calves to weaning) traits of the large FS were generally similar to those of smaller cows in the third and greater parity group. The reproductive efficiency (SANDEX) of large FS at first, second, third and greater parity were lower (p < 0.001) compared to the small and medium FS, due to the later calving dates. Therefore, selecting cattle for the hot and dry climatic regions of Southern Africa, under extensive management conditions and with limited supplementary feeding, the recommended cow frame size should be a medium frame. These animals have similar levels of fertility compared to small framed cows, but with similar or even better growth performances than large framed cows. In the fourth study, the objective was to determine the effect of traits such as age, sex, body weight, body length and height, body condition score (BCS), coat score (CS), skin thickness and average skin surface temperature on tick burdens of a tropically adapted beef breed. Bonsmara cattle (n= 143) were used to measure visible tick counts, body condition score, coat score, skin thickness, body height and length, body weight, body surface temperature, gender and inter calving period. Measurements were taken for a period of eight months from April to December. All animals were managed extensively on natural and cultivated pastures near George in the Southern Cape. Female animals had significantly (p<0.05) greater tick infestation (37.9±2.7) compared to male animals (16.5±1.2). Age was a significant factor p<0.001) with the younger animals below two years having (46.4±5.26) more ticks than those of two years and older (20.1±2.44). A significant negative correlation (r = -0.29; p<0.001) was reported between the infestation of ticks on the animals and the age of the animal. Animals with an average body weight below 250kg had 42% (p<0.05) more ticks compared to animals with a body weight above 250kg. Age of the animal and weight were highly correlated (r = 0.70; p<0.001), while the correlation between the number of ticks per cow and the mean weight was negatively correlated (r = -0.37; p<0.001). Skin surface temperature significantly influenced tick infestation on the animals (p<0.001). The degree of infestation increased as body surface temperature exceeded 30º Celsius. Coat score, skin thickness, body condition score and inter calving period did not significantly influence tick infestation on the animals. The infestation of ticks on the animals was significantly influenced by body height (p<0.019) and body length (p<0.001). Animals smaller than a 130cm in height had a significantly (p<0.05) greater tick infestation (36.5±5.0) compared to animals taller than 130cm (21.2±1.5). This trend was also observed for body length. Animals with a body length shorter than 145cm had a greater (p<0.05) average tick infestation of 41.3±4.5 compared to 23.2±1.3 for animals longer than 145cm, indicating a 44% greater tick infestation for the shorter animals. The selection of cattle for adaptability and thus increased production under tropical conditions, through resistance to ticks should be for animals of medium frame sizes having smoother coats that are able to dissipate heat effectively. In the fifth study, the relationship between growth parameters, scrotal circumference and sheath area in tropically adapted beef bulls was investigated. The relationship between growth parameters such as initial weight at the start of the trial, average daily gain for the trial period (ADG), average daily gain per day of age (ADA), feed conversion ratio (FCR), final weight at the end of the trial, scrotal circumference (SC) and age and sheath area in Santa Gertrudis bulls were examined. To investigate the relationship between growth parameters and scrotal circumference, growth test data of 97 on-station performance tested Santa Gertrudis bulls were used while growth results of 55 Santa Gertrudis bulls tested under semi-intensive conditions were used to investigate the relationship of sheath area with growth performance. Bulls were divided into two groups according to their average sheath area (470 cm2). 28 Bulls were assigned to the small sheath group (SSA) below 470 cm2 while 27 bulls were assigned to the large sheath group (LSA) above 470 cm2. The LSA group possessed a 15% (66 kg; p < 0.05)heavier final weight than that of the SSA group. The LSA group had a 64% (241 cm2; p < 0.05) larger sheath area (378 ± 60 vs 619 ± 161 cm2) than the SSA group. A significant phenotypic correlation between ADG (r = 0.31, p < 0.05) and sheath area was found. The correlations between sheath area and initial weight (r = 0.42, p < 0.001) and between sheath area and final weight (r = 0.45, p < 0.001) were also highly significant. A highly significant correlation (p < 0.001) was observed between initial weight and SC and between final weight and SC, while significant correlations (p < 0.05) were also observed between SC and age and between SC and ADA for bulls tested intensively on station. It appears that SC and faster growth rate are compatible in young bulls. In addition, giving careful attention to sheath area in bulls, selected as yearlings is possible without necessarily sacrificing growth performance. In the sixth study, associations among growth and quantitative testicular traits of tropically adapted yearling bulls fed different dietary energy levels were investigated. High energy (HE), medium energy (ME) and low energy (LE) diets were fed to young Bonsmara bulls post-weaning and the subsequent effects on scrotal circumference (SC), average daily gain over an 84 day performance test trial period (ADG), average daily gain per day of age (ADA), body condition score (BCS), testicular histology and seminal traits were examined. Bulls fed the HE diet were significantly heavier and had a greater ADA, with the HE bulls (999.1 ± 7.13 g) out-performing the ME (804.1 ± 12.61 g) and LE (713.2 ± 12.95 g) bulls in terms of growth rate over the duration of the experimental period. Diet influenced (p < 0.001) BCS with the HE bulls (3.9 ± 0.05) having more body fat compared to the ME (3.3 ± 0.06) and LE (3.0 ± 0.08) bulls with the same effect (p < 0.001) observed in the carcass dressing percentage of the bulls fed different levels of energy. SC did not differ significantly between HE, ME and LE fed bulls. Seminal traits, such as semen concentration were significantly (p < 0.001) lower in bulls fed the HE diet (1.3 ± 0.134) compared to those fed the ME diet (2.4 ± 0.18) and LE diet (2.6 ± 0.16). Similarly, linear movement of sperm was also affected by diet and movement was slower (p < 0.05) in bulls fed the HE diet (1.7 ± 0.30) compared to bulls fed the ME diet (2.2 ± 0.31) and LE diet (3.1 ± 0.23). The percentage total major (p < 0.001) and total minor (p < 0.05) sperm defects were also greater in the HE fed bulls (27.1 ± 6.82 and 7.4 ± 0.91% compared to 9.7 ± 1.45 and 5.5 ± 0.87% for the ME fed bulls and 5.4 ± 1.26 and 3.9 ± 6.58% for the LE fed bulls). Dietary energy level significantly (p < 0.001) influenced the percentage inactive seminiferous tubuli, with bulls fed the HE diet having 35% more seminiferous tubules classified as inactive compared to those bulls fed ME and LE diets. Scrotal fat deposits were higher (p < 0.05) in bulls fed the HE diet (243.4 ± 21.59 g) compared to those fed the ME (110.0 ± 12.1 g) and LE (88.4 ± 9.65 g) diets. Correlation coefficients between SC and growth traits were generally favourable for the different dietary treatments. Correlations between live weight and SC were 0.51, 0.45 and 0.52 (p < 0.05) for the HE, ME and LE groups respectively. A negative association was observed between BCS and progressive sperm motility in bulls fed the HE diet (r = -0.54, p < 0.05). The percentage major seminal defects was negatively correlated with live weight in bulls fed the LE diet (r = -0.46, p = 0.008) and ME diet (r = -0.40, p = 0.08), while this characteristic was negatively correlated with mass movement of sperm (r = -0.63; p < 0.05) and percentage live sperm (r = -0.60; p < 0.05) in HE fed bulls. The present results suggest that feeding HE diets to young bulls influenced their testicular development and reduced their reproductive potential. In the seventh and last study, the relationship between scrotal circumference, quantitative testicular traits and growth performance in tropically adapted yearling beef bulls differing in age was investigated. The bulls were fed a high energy diet and the effect on average daily gain (ADG), average daily gain per day of age (ADA), body condition score (BCS), feed conversion efficiency (FCE), scrotal circumference (SC), seminal traits and testicular histology were examined in Bonsmara bulls (n = 34). The high energy diet contained not less than 11 MJ ME / kg DM and 13.8% CP. Bulls were fed the HE diet from an average starting age of either 210 (YB; n = 17) or 257 days (OB; n = 17) for a total of 112 days. Despite the age difference, growth and carcass traits were similar for the bulls irrespective of starting age. Scrotal weight, scrotal skin weight and scrotal skin thickness were greater (p < 0.001) in the YB (2223.4 ± 11.68g; 576.6 ± 25.17g and 4.5 ± 0.15mm) compared to that of the older group (1010.15 ± 50.10g; 255.9 ± 13.55g and 4.0 ± 0.13mm). The weight of the epididymal / spermatic cord (WESC) was heavier (p < 0.05) in the older bulls (70.2 ± 3.53g) compared to that of the younger group (47.2 ± 3.17g) with a similar trend observed when the volume of the epididymal / spermatic cord (VESC) was measured. Scrotal fat deposition was significantly (p < 0.001) increased by initial age (YB = 1164.7 ± 102.20g vs OB = 263.5 ± 27.52g). Age of the bulls also influenced (p < 0.05) the percentage inactive seminiferous tubuli, with the young bulls having 9.7% more seminiferous tubules classified as inactive compared to the older bulls. Seminal quality showed a similar trend and was generally of a lower standard than that of the group tested at an average of 369 days of age. Semen concentration (p < 0.05) and percentage linear sperm motility (p < 0.08) were the traits most affected by age. A negative correlation was evident between BCS and testis weight (r = - 0.51; p = 0.0342), testis volume (r = -0.52; p = 0.0318) and SC of dissected testis (r = -0.49; p = 0.042) in the young bulls. Correlation coefficients between SC and testis traits such as testis weight and testis volume were high (p < 0.05) for both the groups (YB; r = 0.87 and r = 0.87 and OB; r = 0.77 and r = 0.81). The relationship between SC and scrotal fat (r = 0.85) was highly significant (p < 0.001) only in the younger group. The results suggest that when bulls are fed a high energy diet, the age at which such feeding commences is of importance as regards their subsequent fertility.

Herbicide, Salinity, and Flooding Tolerance of Foxtail Barley (Hordeum jubatum L.) and Desirable Pasture GrassesIsraelsen, Karl R. 01 December 2009 (has links)
Research trials performed in the greenhouse compared the tolerance and response of Hordeum jubatum and desirable pasture grass species to herbicides, salinity, and flooding. Desirable grass species used in this study included: `Fawn' tall fescue (Festuca arundinaceae), `Garrison' creeping foxtail (Alopecurus arundinaceus), `Palaton' reed canarygrass (Phalaris arundinacea), `Climax' timothy (Phleum pratense), `Alkar' tall wheatgrass (Thinopyrum ponticum), `Potomac' orchardgrass (Dactylis glomerata), and `Mustang' altai wildrye (Leymus angustus). Tolerance to herbicides, salinity, and flooding varied significantly among grass species. Herbicide tolerance was tested using four herbicides at five rates each. The herbicides used were imazapic (Plateau), propoxycarbazone (Olympus), sulfosulfuron (Outrider), and flucarbazone (Everest) at rates of 0, 10, 25, 50, 100, and 200 g ha-1. Foxtail barley was least tolerant of sulfosulfuron and propoxycarbazone. Tall fescue, creeping foxtail, and reed canarygrass were susceptible to all the herbicides tested. Timothy and foxtail barley were moderately tolerant while tall wheatgrass exhibited the greatest tolerance to flucarbazone. Orchardgrass was most tolerant to propoxycarbazone. Salinity tolerance was determined by exposing grasses to increasing electrical conductivity (EC) over time. Reed canarygrass and timothy were most susceptible to salinity. Orchardgrass, creeping foxtail, and tall fescue were moderately tolerant of salinity. Foxtail barley, altai wildrye, and tall wheatgrass exhibited the highest tolerances to salinity, and continued to persist at the highest EC levels tested. Flooding tolerance was determined by flooding grasses in 18 cm of water for 2, 4, 6, and 8 weeks. Grasses that were able to extend above the water surface survived, whereas plants that failed to extend beyond the water surface experienced higher mortality rates.

Culturally Adapted Mental Health Treatments: A Meta-AnalysisGriner, Derek 26 March 2007 (has links) (PDF)
In recent years psychologists have increased awareness and concern regarding the quality of mental health services provided to people of color. For several reasons clients of color often find traditional mental health services foreign or unhelpful. To help diminish obstacles faced by clients of color, several authors have advocated traditional mental health treatments be modified to better match clients' cultural contexts. Researchers have also begun investigating outcomes associated with culturally modified mental health treatments, often contrasting them with traditional mental health services. Recently numerous studies containing empirical data have been published. To date there has been no attempt to review this rapidly growing body of literature. Due to the sheer number of studies analyzing the efficacy of culturally modified treatment, the literature has become large and unwieldy. The present study used meta-analytic methodology to gather and organize quantitative data obtained from such studies. Across 80 studies that met criteria to be included in this meta-analysis, the resulting random effects weighted average effect size was d = .44, indicating a moderately strong benefit of culturally adapted treatments relative to traditional treatments. To further examine whether the association of treatment outcome and culturally modified treatments varied as a function of various sociodemographic variables, a series of categorical (and where appropriate, continuous) moderator analyses were conducted. Moderation effects were ascertained only for participant age and for Hispanic populations, with studies consisting of participants of higher chronological age and higher percentages of Hispanic participants having effect sizes of greater magnitude than studies with participants of younger ages or with few Hispanic participants. These results may indirectly provide evidence for the importance of client acculturation, given that older populations tend to be less acculturated (and therefore more in need of cultural modifications) than younger populations and that Hispanic populations are more likely to speak Spanish, necessitating adaptation of therapy to be conducted in their native language. Other variables, such as participant gender, did not moderate the results. Overall, the findings provide evidence for the benefit of modifying psychotherapy to match the cultural context of the client. Recommendations for future research on the topic are provided.

Origami-Based Design for Engineering ApplicationsFrancis, Kevin Campbell 03 September 2013 (has links) (PDF)
Origami can be a powerful source of design inspiration in the creation of reconfigurable systems with unparalleled performance. This thesis provides fundamental tools for designers to employ as origami-based designs are pursued in their respective fields of expertise. The first chapter introduces origami and makes connections between origami and engineering design through a survey of engineered applications and characterizing the relationship between origami and compliant mechanisms. The second chapter evaluates the creasing of non-paper sheet materials, such as plastics and metals, to facilitate origami-based compliant mechanism design. Although it is anticipated that most origami-based design will result from surrogate folds (indirect methods of replacing the crease), it is valuable to provide information that may help in more direct approaches for origami-based design in materials other than paper. Planar sheets of homogeneous material are considered as they maintain the principles fundamental to origami (flat initial state, low cost, readily available). The reduced stiffness along the axis of the crease is an enabling characteristic of origami. Hence a metric based on the deformation of the crease compared to the deformation of the panels enables engineering materials to be evaluated based on their ability to achieve the "hinge-like" behavior observed in folded paper. Advantages of both high and low values of this metric are given. Testing results (hinge indexes, residual angles, localized hinge behavior and cyclic creasing to failure) are presented for various metals and polymers. This methodology and subsequent findings are provided to enable origami-based design of compliant mechanisms. The third chapter proposes a basic terminology for origami-based design and presents areas of considerations for cases where the final engineering design is directly related to a crease pattern. This framework for navigating from paper art to engineered products begins once the crease pattern has been selected for a given application. The four areas of consideration are discussed: 1) rigid foldability 2) crease characterization 3) material properties and dimensions and 4) manufacturing. Two examples are concurrently presented to illustrate these considerations: a backpack shell and a shroud for an adjustable C-Arm x-ray device used in hospitals. The final chapter provides concluding remarks on origami-based design.

Triathlon for all: improving access to sport for people with paraplegia in Trinidad and TobagoSalloum, Kimberly 17 May 2020 (has links)
Globally, people with paraplegia experience reduced participation in sport and physical activity (Blauwet, 2005). This physical inactivity is highly correlated to poor health outcomes, social isolation, and low levels of self-efficacy for people with paraplegia (Rolston, 2014). In Trinidad and Tobago, these rates of physical inactivity are disproportionately higher than rates in developed countries (Richardson, 2018). Interviews with leaders of disability organizations in Trinidad and Tobago revealed that there are limited opportunities for sport/physical activity for people with disabilities, attributed primarily to lack of funding, lack of legislation, and negative socio-cultural attitudes towards people with disabilities. Triathlon for All is a needs-based, evidence-based pilot program aimed at improving self-efficacy and improving overall quality of life for people with paraplegia in Trinidad and Tobago. Triathlon for All is a 12-week adapted triathlon training program with reflective discussion sessions, culminating in a competitive triathlon event. The program will be delivered through the Trinidad and Tobago Occupational Therapy Association (TTOTA). The results from this program will contribute to health promotion and advocacy efforts in Trinidad and Tobago, with the long-term aim of advancing equal rights and opportunities for persons with disabilities in Trinidad and Tobago.

Unité d'Habitation anpassat för ett nordiskt klimat : En studie i klimatanpassad arkitektur och energieffektiviseringar / Unité d'Habitation Adapted for a Nordic Climate : A Study in Climate Adapted Architecture and Energy Efficiency MeasuresHallberg, Knut January 2023 (has links)
Detta examensarbete inom utbildningen Civilingenjör arkitektur inriktning husbyggnad vid Luleå tekniska universitet har fokuserat på att anpassa Le Corbusiers Unité d’Habitation till ett skandinaviskt klimat för att skapa en nära nollenergibyggnad, tänkt att placeras i Norrbotten. Unité d'Habitation är en multifunktionsbyggnad som innehåller element från den sovjetiska kollektivismen och Le Corbusiers idé var att designa en byggnad som innehöll en hel stads funktioner, såsom lägenheter, butiker, en restaurang, ett konstgalleri och ett bibliotek mm. för att minska restiderna och inge en större gemenskap bland de boende. Med hjälp av sina radikala idéer skapade Le Corbusier genom detta projekt, en ikonisk brutalismbyggnad och en arkitektonisk referens av stor betydelse för hans arkitekturarv som jag har studerat genom mitt examensarbete. Projektet begränsades till att designa och konstruera en modern version av Unité d'Habitation anpassad till ett skandinaviskt klimat och vara byggd i hållbara material, som kunde godkännas enligt BBR som en nära nollenergibyggnad, vilket verifierades genom beräkningar med stöd av statistiska data från andra energieffektiva flerbostadshus i norra Sverige. Det har tagit Boverket över fem år att implementera ett fungerande ramverk för nära nollenergibyggnader, vilket används idag genom BBR 29 i Sverige. Slutsatsen av en grundlig forskningsprocess blev att man med tjock isolering, installation av ett FTX-ventilationssystem för återvinning av värmen i frånluften och genom att installera solpaneler för lokal energiproduktion mm. skulle kunna möjliggöra en sådan byggnad, inspirerad av tidigare referensexempel av t.ex. Ralph Erskine och andra moderna energieffektiva byggnader i Sverige. Beräkningarna visade att byggnaden är ca 89 % självförsörjande på energi med hänsyn till värme- och varmvattenbehov. Det är därför troligt att minimivärdet i BBR om EPPET = 0,75 kwh/ kvm per år uppfylls med marginal. Minimikravet på Um värde i BBR 29 om 0,4 W/ (m2 K) skulle sannolikt också vara lätt att nå med tanke på att väggarnas uppbyggnad och de energibesparande åtgärder som vidatagits liknar ett passivhus, vilket mina beräkningar också visat. Byggnaden ritades med ett betongpelarsystem likt Le Corbusiers byggnad, men istället för att genomgående konstrueras i betong används en träpanelfasad konstruerad av limträreglar med 380 mm mineralullsisolering för att möta hårdare energikrav. Den söderorienterade byggnaden har formen av en trapets och med inglasade, öppningsbara terrasser i söder för att förhindra överhettning på sommaren. Inglasningen är täckt med en remsa av solpaneler, vilket även inkluderar taket förutom i norr, samt delvis fasaderna till öst och väst för att göra byggnaden mer energieffektiv. Byggnaden har 10 våningar exklusive garage med 68 lägenheter, butiker, restaurang, gym, café, livsmedelsbutik, basketplan, apotek och spa för att nämna några funktioner. Liksom Le Corbusiers originalbyggnad ger den intrycket av att ha en upplöst fasad genom att balkongerna är indragna i byggnaden, vilket även fungerar som ett klimatskydd. Övriga balkonger samt entrén är även de klimatskyddade. Med prioritet på funktion, energieffektivitet och klimatanpassning, blir byggnaden väl lämpad för det kalla nordskandinaviska klimatet. / This bachelor thesis in Architectural Engineering on the subject of adapting Le Corbusiers Unité d’Habitation for a Scandinavian climate has focused on climate adapted architecture and energy efficiency measures to create a modern Scandinavian version of the building designed as a near-zero energy building meant to be constructed in Norrbotten, Sweden. It is my final work of my education in Architectural Engineering with specialization House Building at Luleå University of Technology. Unité d’Habitation is a multi-function building which contains elements from the Soviet collectivism and Le Corbusiers idea was to design a building containing the functions of a whole city within, such as apartments, stores, a restaurant, an art gallery and a library etc. to reduce travel times and to give a greater sense of community among the residents. Using his radical ideas, he created an architectural reference object of big importance for the brutalism movement and his architectural legacy, which I have studied for this climate adaptive project. It has taken the Swedish Building-Code Authority, Boverket, nearly five years to implement a functioning framework for near-zero energy buildings that is used today. A thorough research process was concluded with that by using for ex. thick insulation, installing a FTX- ventilation system for recycling the heat in the outflow of air and by installing solar panels for local energy production, could make possible such a building inspired by earlier reference examples by Ralph Erskine and later modern buildings in Sweden. The project was limited to design and construct a modern near-zero energy building inspired by Unité d’Habitation adapted to a Scandinavian climate using sustainable materials. This was verified by calculations using statistical data from other energy efficient multi-dwelling apartment buildings and by comparing the structure of the building to other modern energy-efficient buildings and to passive house regulations. The calculations showed that the building is about 89 % self-sufficient on energy with regard to heating and hot water demand. The required minimum Um - value of 0,4 W/ (m2 K) according to BBR 29, would probably also be easy to reach with good margin, considering that the walls and energy-saving measures taken is similar to that of a passive house which my calculations also have shown. The new climate adapted building was designed with a pillar system in concrete like Le Corbusier’s original building but with a wood panel façade instead and with 380 mm internal insulation to improve the energy efficiency. Priority was set on function, energy efficiency and climate adaption for the building to fit the cold northern Scandinavian climate. The south-oriented building has the shape of a partly sloped trapezoid and with glazed terraces to the south. The glazing is sloped and covered with a strip of solar panels to make snow easier sliding down in the winter while also protecting the terraces. The glazing is openable to prevent overheating in the summer. The roof and the façade to the east and west are also completely or partly covered in solar panels. The building has 10 floors plus a garage, 68 apartments, a restaurant, gyms, a café, a basketball court, stores, a kinder-garden school, a grocery store, a pharmacy and a spa to mention a few functions. Like Le Corbusiers original building, the façade gives the impression of being dissolved by having the balconies retracted in the building which also serves as an effective climate protection.
