This study examined the effects of the presence of fungal growth on the phthalate ester content of plasticized polyvinyl chloride (pPVC) used as the vapor barrier component of metal building insulation and the impact the fungal growth may have on the resulting exposure potential to the workers in the building. Individual pieces of the pPVC material exhibiting fungal growth and individual pieces of the pPVC material exhibiting no fungal growth were collected from the building being investigated. Twenty-five pieces each of the pPVC material exhibiting fungal growth and of the pPVC material exhibiting no fungal growth were weighed, reduced to small pieces, and extracted with dichloromethane. The extracts were analyzed using a gas chromatograph coupled with a mass spectrometer. The phthalate content of four phthalate esters identified in the pPVC: diethyl phthalate (DEP), dibutyl phthalate (DBP), butyl benzyl phthalate (BBP), and di-(2-ethylhexyl) phthalate (DEHP), was quantified and the results extrapolated to concentration based on weight ([um]g/Kg) and area ([um]g/m2). A paired samples t test and independent samples t test was used to identify where significant differences occurred (α = 0.05) in the phthalate content between pieces. Using the mean concentration for each phthalate ester, a worst-case-scenario exposure was modeled. There was a statistically significant difference in the phthalate ester content between the pPVC exhibiting fungal growth and pPVC exhibiting no fungal growth for all four phthalate esters investigated. The mean phthalate ester concentration ranged from 13.74 [um]g/m2-34.94 [um]g/m2 in the pPVC exhibiting no fungal growth and 12.00 [um]g/m2-30.63 [um]g/m2 in the pPVC exhibiting fungal growth. The modeled exposure concentration in the building ranged from 0.39 [um]g/m3-0.98 [um]g/m3 and was generally lower than published exposure concentrations in similar settings.

Incorporating insulation material with phase change materials (PCMs) could help enhance the insulation capability for further building energy savings by reducing the HVAC loadings. During the phase change process between the solid and liquid states, heat is being absorbed or released by PCMs depending on the surrounding temperature. This research explores the benefits of a polyurethane (PU)-PCM composite insulation material through infiltrating paraffin wax as PCM into PU open cell foam. The new PU-PCM composite provides extra shielding from the exterior hot temperatures for buildings. Through this study, it was demonstrated that PU-PCM composite insulation could potentially help building energy savings through reducing the loads on the HVAC systems based on the building energy modeling using EnergyPlus. The Zero Energy Lab (ZØE) at the University of North Texas was modeled and studied in the EnergyPlus. It is a detached building with all wall facades exposed to the ambient. It was determined that the new PU-PCM insulation material could provide 14% total energy saving per year and reduce the electricity use due to cooling only by around 30%.

The diploma thesis entitled The influence of building insulation on the costs associated with its operation deals with the design of several variants of building insulation, and subsequent evaluation based on a comparison of operating costs of individual building variants. The theoretical part deals with the history of thermal insulation of buildings, there are types of thermal insulation materials and variants of energy-efficient houses. Then the normative requirements, energy intensity of buildings and methods of thermal insulation of individual building structures are solved. Subsequently, the methods of economic evaluation of the investment and the method of compiling the general budget are addressed. The practical part contains a description of the construction and the proposed variants of insulation, including the calculation of costs, evaluation of the payback period of the investment and evaluation of the proposed variants.

The subject of the work is put forward and evaluate different financing options including thermal insulation of residential building list of essential criteria and generalization optimal procedure. Analysis of the individual components of long-term backup or repair fund, determining the optimum amount of funding inserted before insulation. Determine which folders and to what extent will be affected by thermal insulation of the house. Part of this work is to determine the normal price of a residential building as a whole and explanations of technical terms.

The master’s thesis solves the design and creation of project documentation for the construction of new multifunctional building on parcel 399/30 in the cadastral area Uherské Hradiště - Mařatice. This building plot is intended for construction and is owned by the town of Uherské Hradiště. The location is located in close proximity to the block of flats Pod Svahy. The enclosed building documentation is made in accordance with applicable laws, decrees and standards. Designed multifunctional house is a multipurpose building with one underground and five above ground floors. Basement areas serve as collective garages and backroom areas for residential units. The first floor has a commercial use with cafes, design offices, copy center and a hairdresser. Other above ground floors serve as permanent accommodation in the form of thirteen residential units. A reinforced concrete monolithic skeleton is designed as a support system. The roof is made in the form of a flat roof. The object is based on a base plate.

This thesis deals with the processing of an energy audit of the selected building for daily education. The target of this thesis is an evaluation of the current situation of the building, it means the evaluation of the thermal-technical qualities and energy consuption. For the initial state new measures will be suggested to reduce the energy consuption. One of the measures will be a proposal for an alternative way of supplying of the thermal energy, using the thermal pump. These suggested saving measures will be evaluated, including basic economic analysis.

The energy retrofit of existing buildings has always been a challenging task to accomplish. The example of the Swecohuset building, proves how an integrated approach design between architectural and energetic aspects as well as the use of well-known and efficient technologies are key aspects to achieve the energy-saving goal. This work, in the first part describes the Swecohuset retrofit process, along with the reasons behind the choices which have led to the current result of a reduction by 2/3 of the energy need for space conditioning purposes. Then, in the second part, after a brief focus on the passive aspects which characterize the current energy performance of the building, it is carried out a feasibility analysis of an EWIS (external wall insulation system) by studying its interaction with a complex system as an optimization problem, with the main purpose of understanding the basis of the BPO and explore further building potentialities. / SIRen

The main theme of this Master´s thesis is a project of detached residential house of a terraced type, partially located in terrain. The building has three floors and a basement and is covered by a flat roof. There are six residential units in the house and three parking spaces, including technical support. The house will be built in the village of Pribyslavice, on the plots with parcel numbers 140/1 and 145/1. The ground plan of the house is of a rectangular shape. The vertical load-bearing structural system is chosen to be made from bricks. Horizontal system is made by using Spiroll prestressed panels. The internal staircase is made from concrete, monolithic. The material and construction solutions is chosen to be close to passive standards. The project fully respects currently applicable standards and technical regulations of individual manufacturers.

The subject of this final thesis is prepared detailed project documentation for the reconstruction of apartment building on Karáskovo Square in Brno - Židenice. The existing building is rectangular and is a part of a apartment terraced buildings. Residential building has a basement and three floors and an attic. The main entrance is oriented to the southwest. Foundation structures are concrete, vertical support system is a brick wall, roof structure is wooden roof standing stool with pleated ceramic tiles.
