(OTCBB: [ GRHU ]), a leading provider of energy efficiency solutions and sustainable infrastructure products, today announced that it has been engaged to conduct a complete energy audit of Port Hueneme and Port Mugu within Naval Base Ventura County.

The GreenHouse Energy team will conduct onsite inspections, record measurements and interview appropriate facility personnel. Once complete Naval Base Ventura County will be provided with a report on potential Energy Efficiency Measures (EEM) along with a comparative analysis of energy savings to project cost. Additionally GreenHouse will offer recommendations regarding Automated Demand Response (ADR) opportunities that can be achieved with the appropriate controls equipment and deployment strategy thus taking advantage of Southern California Edison's incentive programs.

"This has been one of my primary goals since the inception of GreenHouse," said John Galt, CEO of GreenHouse Holdings. "Everything we do from residential and commercial construction to sustainable infrastructure to energy efficiency and renewable energy services has been geared to be scalable for a United States military base and thereby supporting the DOD's 2020 mandate for energy consumption."

About Automated Demand Response

The Auto-DR program offers significant financial incentives and technical support to Southern California Edison (SCE) customers willing to install equipment that enables participation in demand response events versus depending on their employees to perform all the curtailment activities manually when required. Normally, control systems (automation) are installed with the programming needed to achieve reductions in electricity consumption during peak periods of demand on the grid. "Participants in SCE's Auto-DR program are in 100% control of the actual curtailment measures implemented on an event-to-event basis. Additionally, the systems commonly implemented for Auto-DR participation are fully capable of being used to improve productivity and equipment operating efficiencies as well as provide users with information that can augment routine and emergency operations and maintenance regimens," adds Robert Davis, Vice President of Energy Services at GreenHouse.
