Estimated Benefits of Achieving Passivhaus and Net Zero Energy Standards in the Region of Waterloo Residential Sector and the Barriers and Drivers to Achieve Them

Kraljevska, Elena January 2014 (has links)
As the third largest energy consumer, the residential sector in Canada is responsible for 17% of energy consumption and 15% of greenhouse gas emissions. With the increase in population, the number of new houses is expected to increase by 2.8 million from 2005 to 2020, and more energy is expected to be consumed despite the emergence of better insulated houses and more efficient heating methods. The primary objective of this study is to determine the prospects of reducing CO2 emissions from the residential sector in Waterloo Region by achieving a higher building standard, such as the Passivhaus (PH) and Net Zero Energy (NZE). The profile of the building envelope, including the initial CO2 emissions was compared against the requirements of the PH and NZE standards, using the Residential Energy Efficiency Project dataset (2007-2012). The second objective evaluates the barriers and drivers that influence the setting of higher building envelope standards. Ontario Building Codes (1975-2012) were analysed to determine the changes to insulation requirements over time, and Ontario Legislative Assembly debates (1970-2012) were reviewed to determine the barriers and drivers expressed in political debates. Content analysis was applied to the Legislative Assembly of Ontario’s documents to determine the frequency of nine word categories prior to each new building code. This study identified three main categories of drivers: awareness of environmental issues, resource limitation, and the implications of climate change; and three categories of barriers: financial, political and structural, and barriers related to information, promotion, and education. The findings of this study confirm that existing houses in Waterloo Region can achieve substantial reductions in CO2 emissions and energy usage by meeting higher building standards. Building code improvements have certainly played an important role in the evolution of Ontario houses, and the 2012 building code, achieves the R-2000 standard universally. More advanced standards show the potential for greater savings, but have only been adopted on a voluntary basis.

[en] ADAPTATION OF THE PASSIVHAUS BUILDING MODEL IN WARM CLIMATES / [pt] ADAPTAÇÃO DO MODELO DE EDIFICAÇÃO PASSIVHAUS EM CLIMAS QUENTES

THIAGO CAVALHEIRO TAVARES 19 June 2017 (has links)
[pt] A certificação Passivhaus de construção se estabelece como uma das principais certificações de eficiência energética alemã na arquitetura. Seu potencial não foi reconhecido somente na Alemanha, mas sim em toda a Europa. Sua metodologia de avaliação leva em consideração a arquitetura passiva da edificação, resultando em uma menor demanda energética para climatização do ambiente. Por se tratar de uma certificação voluntária, desenvolvida para países frios, surgiu a questão de aplicá-la em países de climas quentes, fazendo uso do resfriamento por absorção, resfriamento esse pouco utilizado atualmente devido ao seu baixo rendimento. Os resultados obtidos nesse trabalho comprovam a redução da carga térmica do ambiente através da arquitetura passiva, auxiliada pelo resfriamento por absorção, utilizando a energia solar. Representa avanços na redução do consumo de energia das edificações de forma passiva e por energias renováveis. / [en] The Passivhaus certification is established as one of the leading German energy efficiency certifications in architecture. Its potential was not only recognized in Germany, but across Europe. Its method of evaluation takes into account the passive architecture of the building, resulting in a lower energy demand for ambient conditioning. Since it is a voluntary certification developed for cold countries, it raises the question of its effectiveness when it is applied in countries with hot climates, making use of absorption cooling, which is underused today because of its low efficiency. The results of this work demonstrates that there is a reduction of the thermal load of the environment through passive architecture, aided by absorption cooling using solar energy. It represents progress in reducing the energy consumption of buildings by introducing passive cooling coupled with renewable energy sources.

Solel och solvärme ur LCC-perspektiv för ett passiv-flerbostadshus / PV and solar thermal for a multiple dwelling passive house under a LCC-perspective

Böhme Florén, Simon January 2008 (has links)
This master’s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance. The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST. Solar thermal systems were calculated by hand and with the software Winsun Villa Education. Both softwares use hourly weather data for the calculations. The LCCs are lower for the two reference alternatives than for the solar energy alternatives. The reference alternative with district heating generates the lowest LCC. The alternatives with solar thermal energy replace more energy and have significantly lower LCCs than the PV alternatives. The study also shows the importance of using cheap and environmentally friendly backup energy for producing DHW. When aiming for a quantitative energy use target, the DHW-circulation losses ought to be taken into account as these can be extensive.

Environmentální řešení budovy divadelního sálu a ateliérů v Brně / Environmental solution of the theater hall building and studios in Brno

Znebejánek, Jiří Unknown Date (has links)
This master thesis has two goals: First is to design a Permit Set of Drawings for a combined building of studios, classrooms and theather hall with neccesary auxilary facilities in Brno. Building is detached, five-storey with a basement. In the basement there are garages, theather hall with with facilities and HVAC technologies. The load-bearing structure is prefabricated reinforced concrete frame with ceramic masonry envelope and partitions. Roof is designed as a flat green roof. Building should fulfil the passivhaus requirements. The second goal of the thesis is to assess and compare common metal-based air-conditioning tubing with system based on stone-wool materials called CLIMAVER. The assessment and comparison is based on experimental measurements of the systems’ pressure losses.
