The indoor environment of Kindergartens in terms of Building physics requirements
Jechová, Marie ; Krupica, Roman (referee) ; Bantová, Sylva (advisor)
The thesis titled "The indoor Environment of Kindergartens in Terms of Building Physics Requirements" addresses the challenges associated with ensuring thermal comfort in the indoor environment, while simultaneously providing adequate lighting and daylighting for the classrooms of kindergartens. The thesis is structured into interconnected and complementary sections. The first section dissects the identified problem, establishes legislative requirements, outlines research methods, and defines the objectives, which will be assessed in the conclusion. This section also includes the definition of the kindergarten object in accordance with current legislation. Furthermore, the issues of lighting and daylighting are explained from the perspective of applicable laws, regulations, and standards, incorporating all necessary variables, graphs, formulas, calculations, and definitions. Similarly, subsequent chapters will elaborate on the thermal comfort of the indoor environment. The final section of the theory provides an overview of simulation and computational software tools, employed to model different scenarios, compare the current and proposed conditions, and draw conclusions for the thesis. The practical section follows, focusing on the design of window openings, shading methods, and ventilation regimes to meet the requirements for daily lighting and daylighting while adhering to the maximum indoor air temperature in line with normative requirements. Experimental measurements of essential input data for assessing the thermal stability of the indoor environment were conducted during summer months in the existing facility. In the concluding part of the thesis, conclusions will be drawn regarding the ratio of floor area of transparent parts of building envelopes to the floor area of the classrooms. This is done to ensure compliance with legislative requirements concerning both thermal and lighting comfort in the indoor environment. The conclusion also summarizes potential measures to achieve the desired parameters and outlines a prospective solution to the addressed issues.

Optimisation of light conditions in buildings
Vajkay, František ; Mohelníková, Jitka (advisor)
Building physics as a branch of architecture must ensure an indoor comfort of each user and inhabitant of a building object. This involves, acoustics, indoor thermal conditions and among others also daylighting and artificial lighting of buildings. Light as a particle and an electromagnetic wave, is required by the different aspects of the human organism. It allows the living beings to see, influences skin and bones, the biorhythms, etc. Therefore, it is necessary for the engineering community to predict the correct illuminance and luminance levels acting insides. The thesis deals with such issues. More precisely, it assesses the quality of design tools and methodologies, either against CIE reference cases described in CIE 171/2006 and against real measurements done over the working plane of an indoor space located in the attic of Building D of the Institute of Building Structures, Faculty of Civil Engineering, Brno University of Technology, too. The tools tested throughout the solution of the dissertation did involve three computer programs: RADIANCE, WDLS v3.1 and WDLS v4.1, and one numerographical approach, namely the Daniljuk’s innovated methodology (sometimes even combined with the theories of BRS). In addition several software’s have had been created alongside the process assessment, just to mention the “RADIANCE Script”, “RADIANCE Data Evaluation Script” or “MuuLUX“. The later was written as a communication software allowing the connection of the KONICA-MINOLTA T10 illuminance meter to a computer with the aim of data collection while long term observation. The solution did also require the establishment of a measuring element for the determination of the light reflectance values of surfaces. The solutions, results and conclusions do describe how well did the design approaches deal while predicting the resulting awaited daylight factor levels in points over the working plane.

Chosen Aspects of Light in Sacred Architecture
Šťasta, Jiří ; Kopeček,, Pavel (referee) ; Hrubý, Jan (referee) ; Drápal, Jaroslav (advisor)
Different approaches to the light is emblematic reflection of the current era and it´s cultural a social aspects. The materials are still being developped but the light is everlasting participant of the architecture. The light is basic element which each architect or artist must confront and use it. Due to this we can watch the work with light, analyse it´s use during the ages of the sacred architecture. The work of an architect is situated in the intersection of theoretic and technical fields of human activities. It´s necessary that the artist or architect knows the theoretic aspects of the light but also that knows real numeral values of the coming light. It is good to know the reasons why and for what was the light used in the past and it´s also needed to have a knowledge how much of the light was used in the liturgical space. How much of the light was used in the interior in the past and how much do we use it nowadays? Is it possible to analyse the tendency in the use of the natural light? These questions are useful in forming new liturgical spaces also in nowadays. The first part of this work is focused on the theoretic aspects of the light (liturgy, theology, psychology and ergonomics). The second part of the work describes the measurements of the intensity of the natural light in the sacred spaces in the different selected churches. The conclusion compares different measured values in each sacred building and the results are included to the larger scientific and historical context. The aim of this work was to evaluate specific interior lightning conditions by unified methodology and to apply it on the larger scientific experience which regards the architectonical practice and the forming of the liturgical spaces.
