The "Two State Reactivity (TSR)" was used to analyze the reaction mechanisms; Results showed that the reaction system preferentially involves low-spin state entrance channel and the high-spin state exit channel. In the reaction channel, the crossing point appears, which would effectively reduce the …

Mechanical And Thermal Evaluation Of Different Types Of Pcm-Concrete Composite Panels, Dervilla Niall, Oliver Kinnane, Roger West, Sarah Mccormack

Conference papers

ABSTRACT: Thermal mass indicates the ability of a material to store and release heat and is a function of the heat storage capacity of a material. The thermal mass of construction materials can be used to reduce the energy required for heating and cooling buildings. The heat storage capacity of concrete can be increased by incorporating phase change materials (PCMs) into the concrete and hence providing additional latent heat storage capacity. Research was carried out to compare the thermal behaviour of two different types of PCM/concrete composite panels. The first type of panel was formed by adding microencapsulated paraffin to …

Sustainable Architecture Design: Environmental And Economic Benefits, Michael Babcock

Senior Honors Theses

This thesis examines the movement of environmentalism, and its impact on architecture and construction. During an interview with a professional architect, a basis for research of sustainable design was devised, when he explained that “good” architecture attempts to holistically integrate the external and built environment. Presently, the main measurement for sustainability is energy efficiency. Therefore, architects constantly implement new technology in an attempt to unify both the external and built environment in an energy efficient manner. Furthermore, this thesis provides an environmental and financial cost analysis of implementing sustainable design and build. Research shows that the life cycle and up-front …

In this paper, a preliminary evaluation of the magnitude of such energy loss was conducted by numerical simulations using 3 dimensional transient computational fluid dynamics (CFD) model. A typical layout of recessed lighting fixtures was used in this case study with boundary conditions in four different seasons, which were obtained from past measured roof/attic temperature data sets. The results of the numerical simulations indicate that leakage of recessed lighting …

Identification Of Key Performance Tasks To Demonstrate The Benefit Of Introducing The Facilities Manager At An Early Stage In The Building Information Modelling Process On Public Sector Projects In Ireland., Barry Mcauley

Doctoral

Modelling (BIM) governed process was investigated in this thesis. Governments are now seeking a more rewarding methodology in the management and procurement of public sector building assets. This has seen an integrated focus by International Governments on BIM as a partial solution in both managing and procuring public sector building assets. Despite BIM bringing the Facility Manager closer to project conceptualisation, there was still a reluctance and a lack of perceived benefits of having them involved earlier in the design phase. There remains a lack of clear evidence on what improved contribution the Facilities Manager can provide. This thesis provides …
