The Impact Of Building Form On Energy Consumption In New School Models Of Abu Dhabi, Meriem Rahmani

Architectural Engineering Theses

The high rates of energy consumption by schools are mainly caused by inappropriate designs of architectural forms and limited access to free energy resources that can be provided by natural lighting and ventilation. Optimizing the architectural form with regards to its geometry, aspect ratio, spatial height to depth proportion, form direction, spacing between building masses can help to improve connection to the outdoor environment including daylight, air and outdoor greenery. The optimized form can help not only to save energy but also to create educational environments that are more lively and cheerful; and hence improve students’ performance, health and attitude. …

Performance And Energy Efficiency Analysis Of Data Center Cooling Plant By Using Lake Water Source, Li Ling, Quan Zhang, Liping Zeng

Durham School of Architectural Engineering and Construction: Faculty Publications

A cooling plant by using lake water source was proposed to cool the space in data centers. It combines free cooling technology and variable capacity technology to remove heat and reduce energy consumption effectively. In this paper, firstly, the control strategies for this cooling plant were proposed. Then, a detailed annual energy consumption model with considering the effect of the dynamic heat dissipation characteristics of servers, lake water temperature, outdoor weather conditions, and cooling plant thermal performance, will be established to evaluate the performance and energy efficiency of this cooling plant under different load factors. The results show the mode …

A Review Of Approaches For Sensing, Understanding, And Improving Occupancy-Related Energy-Use Behaviors In Commercial Buildings, Hamed Nabizadeh Rafsanjani, Changbum R. Ahn, Mahmoud Alahmad

Durham School of Architectural Engineering and Construction: Faculty Publications

Buildings currently account for 30–40 percent of total global energy consumption. In particular, commercial buildings are responsible for about 12 percent of global energy use and 21 percent of the United States’ energy use, and the energy demand of this sector continues to grow faster than other sectors. This increasing rate therefore raises a critical concern about improving the energy performance of commercial buildings. Recently, researchers have investigated ways in which understanding and improving occupants’ energy-consuming behaviors could function as a cost-effective approach to decreasing commercial buildings’ energy demands. The objective of this paper is to present a detailed, up-to-date …

The Water Wall: A Passive Solar Collection And Thermal Storage Device For Supplementary Radiant Heating, Rhett Roman Noseck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Through the implementation of passive solar building systems, suburbia could take a fresh new step forward toward a progressively more sustainable direction. Making passive solar strategies a priority, master planned community developments would see opportunity to change the style and design of future suburban residences.

The focus and intention of this body of work is to research, design, fabricate, and test a prototype of a passive solar heating device using water as the medium for thermal storage. The size and shape of the design for the water wall device will be determined by the currently built suburban environment; however, for …

A Comparative Study Of Three Feedback Devices For Residential Real-Time Energy Monitoring, Mahmoud Alahmad, Patrick G. Wheeler, Joshua Eiden, Adam Brumbaugh

Durham School of Architectural Engineering and Construction: Faculty Publications

Residential energy consumption accounts for 21% of the total electricity use in the United States. Unfortunately, research indicates that almost 41% of this power is wasted. Changing the way that consumers use energy may be important in reducing home energy consumption. This paper looks at whether the implementation of certain real-time energy monitors has an impact on the residential rate of energy consumption in a metropolitan area with relatively low electricity rates. In the following case study, 151 Omaha residences were equipped with two variants of the Aztech In-Home Display (Aztech) as well as the Blue Line Power Cost Monitor …
