Gröna byggnader hjälper till att driva den hållbara utvecklingen framåt, vilket behövs inom fastighetsbranschen på grund av dess stora miljöpåverkan. Den fortsatta utvecklingen kännetecknas av problem såsom bristande medvetenhet samt en osäkerhet kring det ekonomiska utfallet. Resultaten som framförs i denna studie bidrar till en ökad förståelse av hur medvetna fastighetsföretag är om gröna bostadsbyggnader samt hur de uppfattar de ekonomiska följderna. Studiens syfte är att belysa hur fastighetsföretag uppfattar de ekonomiskt positiva faktorerna (hyra, vakans, drift- och underhåll, image, inomhusmiljö och risk) som sammankopplas med gröna byggnader. Enbart en del av problemområdet berörs, varvid fokus är på de positiva faktorer som frekvent förekommit i tidigare studier på ämnesområdet. För att besvara syftet har en kvalitativ metod med ett deduktivt ansats valts. Sex fastighetsföretag med varierande miljöengagemang har intervjuats, där samtliga är verksamma i södra Värmland. Intervjufrågorna har baserats på identiskt material för att sedan delvis anpassas efter respektive fastighetsföretag. Resultatet av intervjuerna framkommer i studiens empiriska sammanställning samt analyseras utgående från den teoretiska referensramen. Både likheter och skillnader har observerats. Slutsatsen är att samtliga av de intervjuade fastighetsföretagen värdesätter någon av faktorerna, samt vidrör att ett långsiktigt förhållningssätt är viktigt. Det har framkommit att minskade drifts- och underhållskostnader samt en förbättrad image är de faktorerna som värdesätts högst. Den faktor som företagen anser har minst samband med gröna byggnader är minskad vakans, vilket kan bero på den rådande bostadsbristen. / Green buildings help to drive the sustainable development forward, which is needed in the real estate industry due to its major environmental impact. The continued development is characterized by problems such as a lack of awareness and an uncertainty about the economic outcome. The results presented in this study contributes to an increased understanding of how aware real estate companies are, and how they perceive green residential buildings financial impact. The purpose of this study is to illustrate how real estate companies perceive the economically positive factors (rent, vacancy, operating- and maintenance costs, image, indoor environment and risk) which are linked to green buildings. Only a part of the problem area is examined, whereas focus is going to be on the positive factors which frequently appear in previous studies on the subject area. A qualitative method with an deductive approach has been chosen for this essay in order to answer the purpose of the study. Interviews have been conducted with six real estate companies located in Southern Värmland, whom had varied environmental commitment. The questions that was used have been based on identical material and then been partly adapted after each company. The results from the interviews are stated in the empirical compilation and are being analysed in connection to the theoretical framework. Both similarities and differences have been observed. The concludes are that all of the interviewed real estate companies appreciate some of the factors. All of them mention that a long term approach is of relevance despite their varied startup presumption. It has emerged that the reduced operation- and maintenance cost and an improved image are the most appreciated factors. The factor that the real estate companies consider to have least correlance with green buildings is reduced vacancy, which can be due to the current lack of housing.

The diploma thesis deals with the problems of the indoor environment of swimming pool halls. Firstly, it describes issues and principles of designing HVAC system in the areas with high humidity production. Thesis then focuses on various approaches to calculations of evaporation from the water surface and different possibilities of dehumidification including different types of HVAC units. This knowledge was applied to the design of HVAC system for particular assigned building, for which are proposed two different solutions. Thesis includes experimental part, its aim is to analyse one specific critical part of the hall. Based on local surveying and long-term measurements a few possibilities of improvement are suggested.

The diploma thesis is focused on the issue of ventilation of swimming halls. In the theoretical part, I assess the general issue of air quality in the indoor environment and in swimming halls, ventilation methods and elements for air conditioning in air handling units. In the project part, a complete design of air conditioning for the swimming pool buildings. For ventilation of the pool are created 2 alternative variants of dehumidification of the pool hall and their economic comparison. The experimental part is devoted to the evaporation of water from the water area when moving through water attractions.
