Cogeneration is a simple concept, but sophisticated in engineering and operation. It can reduce energy consumption by 30 to 50% for buildings with the right characteristics. The systems also qualify for significant cash incentives.
It best serves buildings with a 24/7 full operation profile. These types of buildings are :
|Hospitals||Offices with round the clock usage|
|Health care facilities||Multi-unit retirement residences|
|Hotels||Manufacturing and industrial facilities|
Cogeneration can also be applicable to standard office and multifamily residential uses under the right circumstances. It is suitable for both new construction and building retrofit renovations.
The simple payback can be as little as 3 years for the additional cost over a conventional system.
Engines, usually turbines or reciprocating, similar to those used in a car or truck, are run from a fuel source such as natural gas or methane (much cleaner than oil or coal) and sourced locally in the US.
The diagram below illustrates the cycle of an engine producing electricity for the building and the exhaust heat of the engine being captured and converted in a “magic boxes”, actually an absorption chiller and heat exchanger, to cool and heat the building.
COGENERATION MADE SIMPLE
- Will supply 90% of building electrical needs
- Will operate indefinitely if electrical grid goes down
- System is designed with multiple redundancies for equipment
- failures and maintenance shutdowns
- Energy savings of 50%
- Significantly reduces carbon footprint
