Development of new methodologies for evaluating the energy performance of new commercial buildings

Song, Suwon 02 June 2009 (has links)
The concept of Measurement and Verification (M&V) of a new building continues to become more important because efficient design alone is often not sufficient to deliver an efficient building. Simulation models that are calibrated to measured data can be used to evaluate the energy performance of new buildings if they are compared to energy baselines such as similar buildings, energy codes, and design standards. Unfortunately, there is a lack of detailed M&V methods and analysis methods to measure energy savings from new buildings that would have hypothetical energy baselines. Therefore, this study developed and demonstrated several new methodologies for evaluating the energy performance of new commercial buildings using a case-study building in Austin, Texas. First, three new M&V methods were developed to enhance the previous generic M&V framework for new buildings, including: 1) The development of a method to synthesize weathernormalized cooling energy use from a correlation of Motor Control Center (MCC) electricity use when chilled water use is unavailable, 2) The development of an improved method to analyze measured solar transmittance against incidence angle for sample glazing using different solar sensor types, including Eppley PSP and Li-Cor sensors, and 3) The development of an improved method to analyze chiller efficiency and operation at part-load conditions. Second, three new calibration methods were developed and analyzed, including: 1) A new percentile analysis added to the previous signature method for use with a DOE-2 calibration, 2) A new analysis to account for undocumented exhaust air in DOE-2 calibration, and 3) An analysis of the impact of synthesized direct normal solar radiation using the Erbs correlation on DOE-2 simulation. Third, an analysis of the actual energy savings compared to three different energy baselines was performed, including: 1) Energy Use Index (EUI) comparisons with sub-metered data, 2) New comparisons against Standards 90.1-1989 and 90.1-2001, and 3) A new evaluation of the performance of selected Energy Conservation Design Measures (ECDMs). Finally, potential energy savings were also simulated from selected improvements, including: minimum supply air flow, undocumented exhaust air, and daylighting.

A Research On Design Principles In Historic Built Landscapes Case Study: Odunpazari, Eskisehir

Kivilcim, Figen 01 May 2008 (has links) (PDF)
In this thesis, the problem of the principles of new designs in historic built landscapes is discussed. In approaching the problem, a theoretical framework is developed and the general principles regarding new buildings in historic settings are derived from the theoretical context. Subsequently, the proposed principles is tried to be adapted to the case of Odunpazari historic urban fabric. Finally, a Youth Center for a specific Project Area in Odunpazari is proposed, and the integration of the proposal to the context is evaluated. The foremost aim of the thesis is proposing general principles concerning good architecture that continues and contributes to the spirit of place, and adapting them for a specific design problem in a specific place in order to evaluate the efficiency of the principles proposed. In developing the theoretical framework, it was discussed that, in determination of the principles for new designs, the historic built landscape should be handled in a way that resolves the network of relationships and allow the definition of the spirit of place. The methodology of understanding the spirit of place was established with reference to the approaches developed by Christopher Alexander and Christian Norberg-Schulz. According to the studies by these scholars, a triad layer system in resolving the spirit of place is developed. As named by Christian Norberg-Schulz, the layers of Gestalts, typologies and figures constituted the analytical framework leading to the resolution of the network of relationships between the components of a place. This model of analyzing and defining the spirit of place was found valuable, since it does not only focuses on the formal aspects of the historic built landscape, but also questions the main rules forming the unity and coherence of place. Odunpazari traditional urban fabric is selected as a case study, and its physical, historical, social and economical context is evaluated by the help of the literature and site surveys. Finally, a &amp / #8216 / Youth Center&amp / #8217 / in a Project Area in Odunpazari is proposed according to the general principles derived from the theoretical framework, and the results are discussed.

Sportovní a kulturní areál, Otradov / Sports and cultural centre, Otradov

Myška, Jan January 2016 (has links)
The subject of this diploma thesis is the preparation of project documentation for the implementation of new sports and cultural centre Otradov. The dominant feature of the complex objects stands and multipurpose hall. The building is architecturally designed with an effort to fit in too much of rural architecture. Multipurpose hall has two floors, one third roofed flat roof, two-thirds of the roof ridge. The core system is aerated concrete blocks. The building is two-storey grandstand with the carrier deck. Roofing is solved by means of broken wooden beams. Sanitary facilities is dealt wall system and roofed shed roof. Athletics track, the surface of the polyurethane mixture designed for sports.
