Mechanical systems account for approximately 28% of electricity use in California. A high performing system has the ability to produce considerable energy savings with cost savings from 10%-40%. Our mechanical engineers work closely with architects to explore whole building approaches that take into account the building envelope and lighting system for potential savings of 40%-70%. We are focused to reduce energy consumption while maintaining occupant comfort.

As energy prices continue to escalate, the life-cycle cost of a high performance system is relatively low. The simple payback for such systems is typically between three to five years. Furthermore, other technologies such as energy management systems and thermal energy storage may be utilized to reduce peak load. Depending on the utility rate structure, significant amount of monetary savings may come from demand response technologies.

Charlie Yu & Associates offers consulting services to help building owners and architects achieve maximal return on building investment. We will perform life cycle cost analysis and parametric runs to determine the optimal mechanical design.
