The aim of this master thesis is to design an office building for research institute in Brno. In the first part there is designed building structure. The building has two floors. First floor with four offices, toilets, storerooms, kitchen and utility room and second floor with two offices, toilets, conference room, kitchen and two roof terraces. The main entrance is oriented towards north. Load-bearing and non-load-bearing walls are designed from aerated concrete blocks, floor slabs are from cast-in-place reinforced concrete. The building façade is insulated with ETICS. In the second part there are designed systems of heating, mechanical ventilation, cooling, lighting and use of rainwater. Third, cooling analysis of research institute AdMaS in Brno is made. The designs are drawn in AutoCAD, thermal calculations in DEKsoft.

The aim of this diploma thesis is a design of new office building. The construction is situated in the city of Rožnov pod Radhoštěm in the Vsetín district. The building is a detached house and it has three floors and an underground level. On the first floor, there is an entrance hall of the building, a café, educational centre rooms and a tourist information office. On the second and third floors, there is an office area. The underground car park provides fifteen parking spots for the tenants The floor plan of the building is of a rectangular shape. An unroofed atrium, cutting through the inner space, lightens the entire building interior. The building is designed as a monolithic reinforced concrete frame on a base slab. The monolithic frame is designed to be infilled with clay blocks. The house roofing is designed with a flat green roof.

The office building Vråken located in Västerås, Sweden, is soon to be renovated and improved solar shading is considered. In this project, five types of solar shading (zip screens, awnings, window film, built-in venetian blinds and roller blinds) were studied to find out their impact on the building's solar gain, cooling load and thermal comfort. The results were analysed to propose sufficient solar shading. In the early stages of the project a questionnaire was distributed to workers in Vråken with the purpose of finding out their opinions about the thermal comfort in the building. A model of 24 selected rooms in the building was also created in IDA ICE to simulate the five different types of solar shading and compare them to a scenario without any solar shading. The questionnaire was used to calculate PPD, showing that 39,3% of the workers were dissatisfied with the thermal comfort during the summer. The simulations in IDA ICE revealed that, overall, zip screens produced the best results. This was followed by awnings, built-in venetian blinds, window film and roller blinds in that order. Awnings resulted in the smallest solar gain, 62% smaller than without solar shading, while roller blinds resulted in the biggest solar gain, 31% smaller than without solar shading. The cooling load was reduced the most with zip screens (-43%) and the least with roller blinds (-14%) compared to the scenario without solar shading. Operative temperatures were also simulated. Once again zip screens produced the best results and roller blinds the worst. By analysing the results from the questionnaire and the simulations, different solar shading applications were proposed for different parts of the building. For the façade facing south, zip screens combined with a new window film was suggested. For the façade facing north the recommendation was built-in venetian blinds, and facing east and west, zip screens combined with either roller blinds or built-in venetian blinds was suggested. / Energieffektivisering av byggnader är ett tidsenligt och angeläget område. Solen utgör här en viktig roll som naturlig energikälla genom instrålning i byggnader. Under eldningssäsongen är detta välkommet, men under sommaren kan inverkan vara kontraproduktiv med övertemperaturer och ökade kylbehov som resultat. I ett försök att minimera de oönskade konsekvenserna sommartid har i detta arbete fem solavskärmningar (markis, zip screen, persienner, rullgardin och solfilm) undersökts för kontorshuset Vråken i Västerås. Fokusområdet omfattar parametrarna solvärmelast, kyleffektbehov och termisk komfort och har legat till grund för förslag på tillämpning av förbättrad solavskärmning för byggnaden. Arbetet inleddes med en enkätundersökning som delades ut till arbetare i Vråken. Denna syftade till att undersöka den aktuella upplevelsen av inomhusklimatet relaterat till solstrålning och solavskärmning i byggnaden. Huvudmetoden i arbetet var annars modellering och simulering av byggnaden i IDA ICE. 24 utvalda kontorsrum i Vråken byggdes upp med programvaran och utrustades med de beaktade solavskärmningarna i olika fall. Fallen simulerades därpå för att erhålla resultat för de studerade parametrarna. Enkätundersökningen användes för beräkningar av verkligt PPD, ett mått på missnöje beträffande inomhusklimatet. Resultatet visade att 39,3% av arbetarna var missnöjda sommartid. Enkätsvaren indikerade problem med övertemperaturer och värme från solstrålningen, i synnerhet i byggnadens söderläge. Simuleringsresultaten visade att solavskärmning i hög grad minskar såväl solvärmelasten och kyleffektbehovet som den operativa temperaturen i Vråken. Av de beaktade solavskärmningarna var solvärmelasten för byggnaden lägst med markiser (62% lägre än utan solavskärmning) och högst med rullgardiner (- 31%). Solvärmelasten jämfördes mot Miljöbyggnads betygssystem Brons, Silver och Guld. Kyleffekten minskade mest med zip screens (-43%) och minst med rullgardiner (-14%) i jämförelse med fallet utan solavskärmning. För den operativa temperaturen undersöktes både den maximala operativa temperaturen under året och antalet timmar då den överstiger 24°C. Återigen visades på bäst resultat för zip screens och sämst för rullgardiner. Överlag presterade zip screens bäst, följt av markiser, persienner, solfilm och rullgardiner i den ordningen. Vissa variationer fanns mellan byggnadens olika delar (syd-, öst-, väst- och norrläge). Utifrån arbetets simuleringsresultat och enkätundersökning gavs förslag på ny tillämpning av solavskärmning för Vråken. För sydsidan föreslogs zip screens och ny solfilm. På norrsidan var behovet av solavskärmning inte lika stort, men persienner är här en bra lösning. Öst-och västsidan skulle precis som sydsidan nå fördelar genom utvändig solavskärmning. Även här föreslogs zip screens och antingen rullgardiner eller persienner. Alternativa ekonomialternativ presenterades också där det var relevant.

Since COVID-19 was declared a pandemic by the World Health Organization(WHO) in March 2020, teleworking, or working from home, has been used to an increasing extent by companies and organisations all over the world. Evidence suggests that teleworking will become part of “the new normal”, why teleworking-related research will be of value in a long-term perspective. To estimate the potential for energy saving in relation to teleworking, and to identify possible measures to achieve such savings, a literature study and a retrospective case study of an office building in Gävle, Sweden, was conducted. The occupant presence during 2020 was mapped through conversations with representatives of the organisation using the offices. Data logs of energy usage in 2020, in the form of district heating and electricity, were provided by the energy supplier. The results showed that the number of permanent office workers had dropped by just over 40% around the middle of March 2020, and that the occupancy from November 2020 onwards was just over 20 % of that by the beginning of the year. The demand for heating, cooling, and ventilation in an office is the same regardless of the number of people present, which was believed to be the explanation of the lack of covariation between occupancy and district heating supply, as well as between occupancy and HVAC electrical loads. Earlier research has found that a common reason behind lack of impact from occupancy on plug loads and lighting is that equipment and lighting is turned on in office spaces with no one present. This was not the case in the present study. The study failed to identify the reason behind plug loads and lighting having poor correlation with occupancy. Further research of the matter is encouraged. Methods for improving energy efficiency in office buildings in relation to teleworking includes presence-based control strategies for HVAC systems and lighting, energy efficient behaviour, consolidating office space, and hotdesking. Due to the lack of reliable occupancy data, the study failed in quantifying the potential for energy saving in the building, regarding both district heating and electricity. The results give clear evidence of there being an energy saving potential, but not the extent of it. / Sedan covid-19 deklarerades som en pandemi av Världshälsoorganisationen WHO i mars 2020 har distansarbete tillämpats i allt högre grad av verksamheter världen över. Mycket tyder på att distansarbete kommer att bli en del av ”det nya normala”, varför studier på områden relaterade till distansarbete kommer att vara värdefulla ur energieffektiviseringsperspektiv på lång sikt. I syfte att ta reda på hur stor energibesparingspotential distansarbete kan medföra, och att identifiera åtgärdsförslag för att uppnå sådana besparingar, genomfördes en litteraturstudie samt en retrospektiv fallstudie av en kontorsbyggnad i Gävle. Personnärvaron under 2020 kartlades i samtal med representanter för den verksamhet som har kontor i byggnaden, medan uppgifter om energitillförseln, fördelad på fjärrvärme, fastighetsel och verksamhetsel, tillhandahölls av energileverantören. Det framkom att den fasta personnärvaron sjunkit med drygt 40 % i mitten av mars 2020, och att den från och med november 2020 utgjorde drygt 20 % av närvaron vid årets början. Inga samvariationer mellan energianvändning och personnärvaro observerades, och tillförseln av såväl fjärrvärme som fastighetsel och verksamhetsel var densamma vid årets slut som vid dess början. Behovet av uppvärmning, kylning och ventilation i ett kontor är detsamma oavsett hur många personer som befinner sig i det, vilket bedömdes vara orsaken till bristen på samvariationer mellan personnärvaro och fjärrvärme respektive fastighetsel. Tidigare studier har visat att en vanlig orsak till att personnärvaro har liten påverkan på verksamhetselkonsumtion är att utrustning och belysning är påslagna även i utrymmen där ingen uppehåller sig. Så var inte fallet i föreliggande studie. Studien kunde inte identifiera orsaken till att användning av verksamhetsel inte följde variationerna i personnärvaro, varför ytterligare forskning är nödvändig. Metoder för energieffektivisering i kontorsbyggnader vid distansarbete inkluderar närvarostyrd teknologi, energimedvetet beteende, minskning av totalt utnyttjat kontorsutrymme samt hotdesking. Då personnärvaron inte kunde kartläggas med tillfredsställande precision i föreliggande studie var det inte möjligt att kvantifiera byggnadens energieffektiviseringspotential, varken för fjärrvärme eller elektricitet. Studiens resultat visar tydligt att energibesparingspotential föreligger, men inte i vilket omfång.
