Prior to implementing the district GSHP system, 47 major buildings in BSU were served by a central steam plant with four coal-fired and three natural-gas-fired steam boilers. The new district GSHP system replaced the existing coal-fired steam boilers and conventional water-cooled chillers. It uses ground-coupled heat recovery HR chillers to meet the simultaneous heating and cooling demands of the campus.
The actual performance of the GSHP system was analyzed based on available measured data from August through Julyconstruction drawings, maintenance records, personal communications, and construction costs. The annual energy consumption of the GSHP system was calculated based on the available measured data and other related information. It was compared with the performance of a baseline scenario— a conventional water-cooled chiller and natural-gas-fired boiler system, both of which meet the minimum energy efficiencies allowed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers ASHRAE The comparison was made to determine source energy savings, energy cost savings, and CO2 emission reductions achieved by the GSHP system.
A cost analysis was performed to evaluate the simple payback of the GSHP system. The following sections summarize the of the analysis, the lessons learned, and recommendations for improvement. Cross flow filtration for radwaste applications reverse osmosis demonstration case studies.
Today's radwaste economic and regulatory scenarios ify the importance in the improvement of operational practices to reduce generator liabilities. This Mature lonely in Oulad Mekalla is largely due to the rising cost dealing with burial sites and the imposed waste volume restriction.

Resource Conservation and Recovery Act permit modifications and the functional equivalency demonstration : a case study. Hazardous waste operating permits issued under the Resource Conservation and Recovery Act RCRA often impose requirements that specific components and equipment be used.
A study was performed to determine whether the redeed unit would qualify as functionally equivalent to the original component. In performing this studythe following steps were taken: a the key performance factors were identified; b performance data describing the existing unit were obtained; c performance of both the existing and redeed units was simulated; and d the performance data were compared to ascertain whether the components could qualify as functionally equivalent.
In this casethe key performance data included gas residence time and distribution of flow over the activated carbon. Because both units were custom deed and fabricated, a simple comparison of manufacturers' specifications was impossible. Therefore, numerical simulation of each unit de was performed using the TEMPEST thermal-hydraulic computer code to model isothermal hydrodynamic performance under steady-state conditions.
The of residence time calculations from the model were coupled with flow proportion and sampled using a Monte Carlo-style simulation to derive distributions that describe Mature lonely in Oulad Mekalla predicted residence times.

Specification aggregate quarry expansion: a case study demonstrating sustainable management of natural aggregate resources. Many countries, provinces, territories, or states in the European Union, Australia, Canada, the United States, and elsewhere have begun implementing sustainability programs, but most of those programs stop short of sustainable management of aggregate resources. Sustainable practices do not always have to be conducted under the title of sustainability.
This case study describes how Lafarge, a large multinational construction materials supplier, implemented the principles of sustainability even though there was an absence of existing local government policies or procedures addressing sustainable resource management. Jefferson County, Colorado, USA, is one of three counties in the six-county Denver, Colorado, region that has potentially available sources of crushed stone.
Crushed stone comprises 30 percent of the aggregate produced in the area and plays a major role in regional aggregate resource needs. Jefferson County is home to four of the five crushed stone operations in the Denver region.
Lafarge operates one of those four quarries. Lafarge recently proposed to expand its reserves by exchanging company-owned land for existing dedicated open space land adjacent to their quarry but owned by Jefferson County. A similar proposal submitted about 10 years earlier had been denied. Contrary to the earlier proposal, which was predicated on public relations, the new proposal was predicated on public trust. Although not explicitly managed under the moniker of sustainability, Lafarge used basic management principles that embody the tenets of sustainability.
To achieve the goals of sustainable aggregate management where no governmental policies existed, Lafarge not only assumed their role of being a responsible corporate and environmental member of the community, but also assumed the role of facilitator to encourage and enable other stakeholders to responsibly resolve legitimate concerns regarding the Lafarge quarry proposal. Lafarge successfully presented an enlightened.
One of the selected demonstration projects was proposed by Montana Tech of the University of Montana for a 56, sq ft, newly constructed, on-campus research facility — the Natural Resources Building NRB located in Butte, Montana.
This demonstrated GSHP system consists of a 50 ton water-to-water heat pump and a closed-loop ground heat exchanger with two redundant 7. It works in conjunction with the originally installed steam HX and an aircooled chiller to provide space heating and cooling. It is coupled with the existing hot water and chilled water piping in the building and operates in the heating or cooling mode based on the outdoor air temperature. The ground loop pumps operate in conjunction with the existing pumps in the building hot and chilled water loops for the operation of the heat pump unit.
The goal of this demonstration project is to validate the technical and economic feasibility of the demonstrated commercial-scale GSHP system in the region, and illustrate the feasibility of using mine waters as the heat sink and source for GSHP systems. Should the demonstration prove satisfactory and feasible, it will encourage similar GSHP applications using mine water, thus help save energy and reduce carbon emissions.
The actual performance of the system is analyzed with available measured data for January through July The annual energy performance is predicted and compared with a baseline scenario, with the heating and cooling provided by the originally deed systems. The comparison is made in terms of energy savings, operating cost savings, cost-effectiveness, and environmental benefits. One of the selected demonstration projects was proposed by Furman University for ten student housing buildings—the North Village located on the campus in Greeneville, South Carolina.
All ten buildings are identical in floor plan and construction. Each building is conditioned by an identical GSHP system consisting of 25 water-to-air heat pump WAHP units, a closed-loop vertical ground heat exchanger GHX installed under an adjacent parking lot, and two redundant 7. The actual performance of the GSHP systems is analyzed with available measured data for The annual energy performance is compared with a baseline scenario in which the building is conditioned by air-source heat pumps ASHPs with the minimum allowed efficiencies specified in ASHRAE Standard Finally, limitations in conducting this analysis are identified and recommendations for further improving the operational efficiency of the GSHP systems are made.Mature lonely in Oulad Mekalla
