Building Optimisation: Re-commissioning Your Building to Deliver Peak Performance
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
Every building undergoes changes over time. As departments are created and dissolved, people are moved around, spaces are repurposed, and interior structures are adjusted. While good for business, these changes can negatively ...
Effectiveness of Shading Air-Cooled Condensers of Air-Conditioning Systems
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
In air-conditioning (A/C) systems with air-cooled condensers, the condensing unit has to be kept in the open for easy access to outdoor air in order to efficiently dissipate heat. During daytime, the solar radiation falling ...
Energy Savings in Direct Evaporative Cooling: real application in the Madrid metro and simulated application for offices in Sydney
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
Water evaporates spontaneously in contact with the air, absorbing around 680 W/(kg/h of evaporated water) from the air (1,053 BTU/lb.). Direct Evaporative Cooling (DEC) exploits this simple physical phenomenon to achieve ...
Reduced Energy and Maintenance Costs Using Polyurethane as a Replacement Roof System
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
Reduction in maintenance and allied costs was the number one priority when Texas A&M University first considered polyurethane foam as a replacement roof for existing buildings. An investigation revealed
that when properly ...
Energy Savings in Electric Arc Furnace Melting
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1982)
Arc furnace melting which at one time was almost exclusively used to produce alloy steel and steel castings is now widely accepted in the industry as an efficient process to produce all types of steel and iron. Presently, ...
Computer Optimization of Steam Production
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1982)
As fuel costs continued to rise sharply during the 1970' s, the staff at Exxon's Benicia Refinery realized there was a growing economic incentive to optimize the production of high pressure steam. A significant percentage ...
Energy Use and Savings in the Canadian Industrial Sector
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1982)
The changing role of energy as a production input in the industrial sector in Canada is examined. Energy use patterns are reviewed in terms of the energy input types, both purchased and self-produced, the actual energy ...
Energy Savings Accomplished by Replacing Steam Ejectors with Electric Driven Vacuum Pumps in Crude Distillation Vacuum Towers
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1982)
The low cost of steam combined with the maintenance free operation of steam ejectors has assured their unquestioned use in providing the necessary vacuum for crude distillation vacuum towers. However, the cost of steam ...
Retrofits: A Means for Reducing Energy Consumption in Ammonia Manufacture
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1982)
The manufacture of ammonia is an energy intensive process. Existing large scale plants typically require 33-40 MM BTU (LHV)/ST as energy input. New plant designs can achieve energy levels below 27 MM BTU (LHV)/ST. Therefore, ...
Steam System Optimization: A Case Study
(Energy Systems Laboratory (http://esl.tamu.edu), 2000-04)
This paper highlights the study findings in a steam system in a plant from a multinational Petrochemical giant in an European country. The steam system operates with an annual budget of $8.9 million (local currency was ...
