Steam Efficiency

Distribution

Distribution entails the routing of steam from its origin to (and within) buildings served by a steam loop.  Distribution utilizes pressure differentials as steam branches into buildings and away from distribution mains. This in turn depends on the use of pressure regulating valves, meters, steam traps, insulation and interconnecting pipes. Leaks are an unavoidable consequence of utilizing such hardware, but their frequency and impact can be minimized through equipment standardization and maintenance routines.

End-Use

End-Use involves transferring the latent heat of the steam to interior spaces and into application such as cooking, laundry, and sterilization. Invariably, these tasks are complicated several times over in an institutional environment. One dimension is the disparate heating demand coming from the many rooms and buildings served by on steam system. Well planned routine heat loss prevention, and dedicated maintenance enable such a system to work effectively.

Condensate Recovery

Recovery stages of steam operations involve the recapture of heat present in the condensate as well as treatment of combustion gases. Condensation discharge is a normal consequence of a complicated distribution system. Proper design and maintenance however maximizes usable heat as a proportion to boiler output. The optimization and recovery of thermal resources, including combustion heat, distribution surplus, and end-use optimization, all serve as a means for reducing expenditures on fuel and other steam inputs.

SERVICES

Audit & Design

Envocore Water Efficiency Services provides comprehensive Audit and Design services based upon field-proven methods to minimize on-site water use, without impacting the mission of the facility or the tenants. Envocore Water Efficiency Services’ Audit and Design team has extensive experience in meeting the needs and requirements of all types of facilities.

Analysis

Envocore Water Efficiency Services provides a complete water use and savings analysis that can be customized to meet the needs of each individual client. The savings and costing are calculated on a solution by solution basis and are subsequently summarized by building or facility. Operational hours, census information and various other data are used in the analysis to determine savings.

These savings establish the return on investment (in years) by comparing the total cost of the project (labor, material, and waste removal) versus the annual savings.

Upon completion of the initial savings analysis the design is reevaluated using various alternative value engineering techniques to determine if any additional savings may be achieved while maintaining the primary design intent.

Implementation Team

The Implementation Team is selected based upon specific expertise in the construction measures to be implemented.
