This project is aimed at building public swimming pool – swimming pool whose lenght is 25 meters, children´s pool, relaxation pool, whirlpool and the sauna area which consists of three saunas. The proposed project has two floors and one basement with dimensions of 70,2 x 33,5 m. The build-up area is 2352m2 . Flat roof with compact structure with a foam glass. The roof carry wooden glulam beams. The thesis can be used as a basis of the building procedure.

The subject of the project is new building of indoor swimming pool with gym with dimensions of 63,2x32,4 m and guest capacity of approximately 250 000 people per year. The project is located in Valašské Klobouky (parc.č. 2210/1, 2200/11, 2203, 2194, 2210 / 3, 2210/35 in the cadastral area of Valašské Klobouky) owned by the city Valašské Klobouky. In the neighborhood, there is took place building of primary schools, kindergartens, health centers and boarding house for seniors. Location of buildings on the property (built-up area of approximately 1934 square meters) is based on the requirement to continoue to the existing complex of objects with maximaly utilization of space and orientation to the quarters. The building is divided into two parts by volume. From an operational point of view is divided into three functionally different parts ie. A cafe, gym and indoor pool. The parts are divided by materials. Café, entry and operational facility is from supporting skeleton system, which is equipped with a facade of cladding panels in a uniform grid in combination with glass facade. The supporting part of the hall with pools and gym is consisted of laminated wooden trusses, which hold up the roof and cladding with sheeting of TiZN. Southwest facade of pool hall, toward to the health center, is fully glazed. Glazed stripes are also between individual segments of glulam wooden trusses of hall and ensures even natural lighting of the hall.

La piscine fait partie des établissements publics les plus fréquentés dans notre société. En effet, il ne s’agit pas uniquement d’un lieu de pratique d'activités physiques, mais également un espace de détente, de jeu, d’éducation et de lien familial. Il est de toute évidence essentiel, de fournir un environnement intérieur confortable et sain pour ses occupants. Cependant, en raison de sa dimension, son besoin excessif en énergie et la complexité des phénomènes physiques évoluant à l’intérieur, il est difficile de parvenir à un équilibre optimum entre : qualité de l’air intérieur, confort thermique des occupants et efficacité énergique du bâtiment. Il faut pour cela, parvenir à une description des mécanismes qui façonnent la structure de l’écoulement de l’air par une analyse profonde de ces phénomènes qui sont à l'origine des transferts de chaleur et de masse mis en jeu à l’intérieur. Ainsi, l’objectif visé de cette thèse est de présenter une étude numérique thermo aéraulique, par CFD en régime stationnaire et transitoire, qui permet d’évaluer le comportement dynamique, thermique et thermodynamique des différents phénomènes physiques qui évoluent à l’intérieur de la piscine intérieure semi-olympique de l’université Bishop’s (Sherbrooke, Canada) afin d’améliorer la qualité de l’air intérieur et le confort thermique ainsi que son rendement énergétique. Les simulations sont réalisées avec le logiciel libre OpenFOAM en utilisant une approche RANS. Une étude thermo-aéraulique par CFD a d’abord été réalisée sur une cavité rectangulaire avec plancher chauffé, afin d’appréhender les simulations thermo aérauliques. Cela a abouti à la détermination de la meilleure configuration d’aération pour une qualité de l’air et un confort thermique optimum. Plusieurs simulations CFD du flux d'air tridimensionnel avec transfert de chaleur et de masse ont été aussi effectuées ultérieurement pour la piscine, afin d’évaluer les effets des conditions climatiques extérieures et ceux des nageurs sur l'atmosphère intérieure. En adoptant plusieurs modèles de turbulence de type RANS, la comparaison des résultats obtenus avec les données expérimentales de référence a permis de valider le code OpenFOAM. Les données expérimentales ont été recueillies au préalable au sein de la piscine de l’Université Bishop’s à l’aide d’un dispositif conçu et adapté aux conditions internes propre à la piscine et qui est équipé de plusieurs capteurs pour la mesure de : température, humidité relative et vitesse. Enfin, une étude thermo-aéraulique de la piscine en régime turbulent transitoire pour une durée de 24 heures pour les jours typiques d'été et d'hiver a été réalisée afin de prédire l’évolution de la distribution des paramètres tels que la vitesse, la température et l'humidité relative. Une analyse statistique a permis de montrer que les conditions climatiques extérieures n'ont pas d'effet sur l'environnement interne de celle-ci. D’ailleurs, sa très bonne isolation thermique démontrée par un calcul détaillé des pertes thermiques à travers son enveloppe confirme ce constat. D’autre part, l’évaluation de la qualité de l'air intérieur et le confort thermique des occupants a révélé que ces derniers sont inacceptables. Suite auxquels, un ajustement des paramètres de conditionnement de l’air a été apporté pour fin d’amélioration. / Abstract : The swimming pool is one of the most popular public establishments in our society and is not just a place for physical activities but also a space for relaxation, play, education and family ties. It is therefore important to ensure a healthy and comfortable indoor environment for the occupants. However, given the size, energy requirement and complexity of the physical phenomena that take place within such space, it is difficult to achieve an optimum balance between interior air quality, thermal comfort of occupants and energy efficiency of the building. This requires a description of the mechanisms, which determine the structure of the airflow by a profound analysis of these phenomena, which are the origin of the heat and mass transfers involved inside such spaces. The objective of this thesis is to present a numerical thermo-ventilation study using CFD (computational fluid dynamic) in stationary and transient regime that allows to evaluate the dynamic, thermal and thermodynamic behaviors of the various phenomena that take place inside the semi-Olympic closed swimming pool at Bishop's University (Sherbrooke, Qc, Canada). The aim is to improve the indoor air quality and thermal comfort of occupants as well as its energy efficiency. The simulations are carried out using OpenFOAM (Open Field Operation and Manipulation) using a Reynolds-Averaged Navier-Stokes (RANS) approach. To do this, a CFD thermo-ventilation study was first carried out on a rectangular cavity with heated floor in order to understand the thermo-ventilation simulations. This has led to the determination of the best ventilation configuration for optimum air quality and thermal comfort. Several CFD simulations of the three-dimensional airflow with heat and mass transfer were also carried out later for the indoor swimming pool to evaluate the effects of outdoor climatic conditions and swimmers on the indoor atmosphere of the pool. By adopting several RANS turbulence models, the comparison of the results obtained with the experimental data allowed to validate the OpenFOAM code. The experimental data were collected in the pool at Bishop's University using a device designed and adapted to the pool’s internal conditions. The devise is equipped with several sensors to measure temperature, relative humidity and velocity. Finally, a thermo-ventilation study of the swimming pool in transient turbulent regime for a duration of 24 hours for typical days of summer and winter was conducted in order to predict the distribution of the various parameters such as velocity, temperature and relative humidity. A statistical analysis showed that the external climatic conditions have no effect on the internal environment of the swimming pool. Moreover, its good thermal insulation demonstrated by a detailed calculation of the thermal losses through building envelope confirms this observation. On the other hand, the evaluation of the indoor air quality and the thermal comfort of occupants revealed that the conditions inside the pool are unacceptable. After which, an adjustment of the air conditioning parameters was made for improvements.

Många av Sveriges badhus byggda i slutet av 1900-talet börjar idag visa tecken på kraftiga fuktskador på grund av extrema inomhusklimat. Denna rapport förklarar den allmänna problematiken kring högt fuktbelastade byggnader och berör det fuktskadade badhuset Aquarena i Katrineholm.  Extrem noggrannhet krävs vid montering av ångspärr i en konstruktion, speciellt vid högt invändigt fukttillskott. Optimal placering av fuktspärren i konstruktionens varmare del innebär att fukt aldrig tillåts kondensera och därmed minimeras risken för fuktskador och negativa konsekvenser. Verkligheten visar också att om kunskaper om fukt och fuktskador prioriteras redan i ett tidigt stadium under projektering kan många hundratusentals kronor sparas. Beräkningar av fukttransport har gjorts för tidigare ytterväggskonstruktion i Aquarena (den som drabbats av skador) och nybyggd ytterväggskonstruktion (nyframtagen till återuppbyggnaden) i datorprogrammet WUFI Pro 4.2 och analyserats i WUFI Bio 3.0.  Beräkningarna visar att den tidigare väggkonstruktionen får de skador som undersökningar av den visat och att skadorna hade kunnat undgås om genomförningar i ångspärren hade utförts på ett korrekt sätt.  Vi har med beräkningar inte kunnat bevisa att alla delar i den nybyggda ytterväggskonstruktionen kommer fungera perfekt. Främst beror osäkerheten i beräkningar utförda i WUFI på att beräkningsmodellen inte är färdigutvecklad. Osäkerheter beror också på otillräcklig kännedom av egenskaper hos de simulerade materialen. Beräkningar för den nyframtagna väggkonstruktionen visar dock entydigt på bättre resultat än för den tidigare väggkonstruktionen. Det finns därför anledning att vidare utreda vilka värden på fukt och temperatur som kommer att råda över de närmaste åren. Detta bland annat för att senare kunna korrigera beräkningsmodellen efter verkligheten. / Many of Sweden's public indoor swimming pools built in the late 1900’s are beginning to show signs of excessive moisture damage due to extreme indoor climate. This report explains the general problem of high moisture-loaded buildings and involves the moisture-damaged public indoor swimming pool Aquarena in Katrineholm. Extreme care is required when assembling the moisture barrier in a structure, especially with high internal moisture content. Optimal placement of the moisture barrier in the warmer parts of the construction means that moisture is never allowed to condense, thus minimizing the risk of moisture damage and negative consequences. Reality also shows that if risks of moisture and moisture damages are assessed early in the planning process, amounts in the range of hundreds of thousands of Swedish crowns can be saved. Calculations of moisture transport have been made for the previous exterior wall structure (the one that suffered damage) and new exterior wall structure the (new design for the reconstruction) using the computer program WUFI Pro 4.2 and analyzed in WUFI Bio 3.0. Calculations show that the old exterior wall structure in Aquarena would have been able to withstand moisture damage and damages due to moisture if joints and transitions in the moisture barrier had been correctly performed.  Calculations have not proven that all elements of the newly built wall design will work perfectly. The main reason for uncertainty in calculations when using WUFI is that the calculation model is not fully developed. Uncertainty is also due to insufficient knowledge of properties of the simulated materials. However, calculations show unambiguously better results than the previous wall construction. It is therefore necessary to further investigate what values of humidity and temperature will exist over the next few years to be able to later on correct the calculation model after reality.

The aim of the diploma thesis was to design reinforced concrete construction of the indoor swimming pool and ensure impermeability of the construction, to ensure behavior as concrete tank construction. Static analysis was done by using program Dlubal RFEM 5.12, where interaction of subsoil with construction was taken into account. Slabs around the swimming pool area were divided into expansion section because of temperature changes from glass façade an after that the sealing of expansion gap was solved. Construction system under the swimming was designed and was tested the behavior of walls and slabs. Analysis was done also to considerate of hydration heat. The drawing was done by software CADKON RCD.

Diploma thesis is focused on design of a new hotel in mountain surrounding with one underground floor and five stories. The hotel has 53rooms for guests from the second to the fifth floor and two rooms for employees of hotel on the fifth floor, what means 106 beds for guests. The hotel is equipped indoor swimming pool 25x10meters, its own kitchen, dining hall, sauna, massages and Conference hall. The object consists of four dilatation units – accommodation sides and common central part and swimming pool. Roof construction is created by huge wooden truss from the second floor to the fifth floor, which sequentially subsides and formed by 70 dormers. Angle of the roof is 46° and 23°, and surface coating is smooth titanium zinc sheet. Load bearing system of whole object is designed as irregular reinforced concrete monolithic skeleton from concrete C30/37 with prestressed elements and based on prestressed reinforced concrete slab. The cladding is designed from ceramic bricks with inner additional insulation and additional insulation on outer surface, which is covered by facade with ventilated air gap, designed from cement-fibers boards, which are by color and structure imitating natural stone. Each accommodation floor is divided into two accommodation sides, central part with central stairs and two personal elevators. Each accommodation side has two protected escape routes and one fire evacuation lift. On the Ground floor, there is the reception, the dining hall, the pool hall and offices. On the underground floor, there is wellness center for guests of the hotel, technologies for the pool, HVAC engine room and kitchen. In all object, there are designed different types of hanging ceilings, because of attendance of stabile sprinkler system. In the pool hall, there will be acoustic hanging ceiling. Heating will be procured by combination of biomass boiler and heat pumps, which will be used mainly for deck heating in rooms in accommodation floors.
