Here is Green DCV system and some of the q/a's from the site. I am going to get the federal monies set aside in stim bill for EXACTLY what this system can do for a federal, state or local bldg...from schools to courthouses to almost everything high, low and in btw in size...and the American Recovery Act has put BILLIONS aside to get done what the Green DCV system does-- Green DCV Intelligent, Cost Affordable, Efficient Green DCV is the ideal solution to increase comfort, productivity, and health while keeping your company's costs in mind. istock_000005167967xsmall.jpgCemtrex's Green Demand Control Ventilation combines several proven technologies to provide maximum energy savings and maximum comfort simultaneously. It offers ventilation control strategies for buildings of all sizes by a company with more than several decades of emissions analysis experience, Cemtrex. The state-of-the-art ventilation control by Green DCV, achieves energy savings by precisely controlling the flow of outside air into a building based upon occupancy levels. This is done by continuous multiple parameter monitoring of CO2, non-human generated pollutants, and other comfort related factors simultaneously in several zones in a multiplexed commercial building. Green DCV incorporates economizers into its design as well to provide efficient energy consumption while reducing unnecessary expenses. The remarkable thing about the Green DCV is that it can be installed into any facility as a stand alone system requiring virtually no modification to the existing HVAC system. How does Demand Control Ventilation really work? ---answer--> Demand Control Ventilation What is Demand Control Ventilation (DCV)? Demand Control Ventilation is a ventilation control strategy that can help optimize the performance of the HVAC units in a facility. The HVAC units often times are the most energy consuming portions of buildings and thus the impact they have on the environment is enormous. In addition to the reducing the environmental impact, improving the performance of the HVAC unit can generate significant energy savings for building owners and companies alike. DCV ventilates buildings using occupancy levels to provide necessary fresh air throughout the building. Fresh air in buildings is essential to the health and comfort of occupants. But bringing in an unnecessary amount of outside air to ensure adequate indoor air quality doesn’t have to be such a drain on your company’s bottom line. There’s a more efficient and affordable way to meet fresh air requirements in your building and lower your energy costs. Demand controlled ventilation (DCV) adjusts ventilation rates based on actual occupancy at any given time instead of at a fixed rate for full occupancy. By monitoring carbon dioxide levels the amount of people inside can be determined, which in turn signals the HVAC system to adjust the amount of outside air brought into the building on a per person basis. Reduced energy usage: DCV reduces the amount of excessive outside air that needs to be cooled and/or dehumidified. A typical business may reduce air conditioning energy costs by 10 percent or more a year depending on the varying occupancy. Increased system efficiency: By eliminating over-abundant fresh air, DCV helps your HVAC equipment operate more efficiently and last longer. Ensures proper indoor air quality: DCV will comply with fresh air requirements more efficiently than your HVAC system’s fixed ventilation rate. Federal, State, and Local agencies offer incentives which will vary based on your building type and square footage of air conditioned space. Call us or speak to your representatives to find out how you can tap into available funds to implement DCV in your building. How can Green DCV really save me money? -answer---> Energy Savings Energy Efficiency and Sustainability in Buildings The impact of buildings on our planet is enormous and is a prime example of where energy waste can be reduced, both creating a healthier environment, indoors and out, and reducing our energy demand. Reducing our energy consumption by making our buildings more efficient and using sustainable materials, means less greenhouse gas emissions and more money in your pockets. The growing demand for energy independence and the campaign to fight global warming has created an enormous backing to start retrofitting buildings in the United States to make them more efficient. With the new federal administration in office, and the increasing awareness at the state and local levels, incentives for Green programs have never been as abundant. The bottom line is that buildings need to be greener and now things are being done about it. The value of green building construction is projected to increase to $60 billion by 2010. In the United States alone, buildings account for: * 72% of electricity consumption * 39% of energy use * 38% of all carbon dioxide (CO2) emissions * 40% of raw materials use * 30% of waste output (136 million tons annually) By 2009, 82% of corporate America is expected to be greening at least 16% of their real estate portfolios; of these corporations, 18% will be greening more than 60% of their real estate portfolios. Sectors Expected to have Green Building Growth * Education * Government * Industrial * Office * Healthcare * Hospitality * Retail Where can be Green DCV be used? ---answer---> Applications Who should install DCV technology? If your business has long operating hours, where occupancy varies greatly and is unpredictable, you can benefit from DCV. Buildings that seldom or never reach maximum occupancy are likely to save the most energy. Green DCV is ideal for a variety of buildings including: istock_000002662526xsmall.jpg * Schools and Universities * Offices of all Sizes * Shopping Malls, Movie Theaters * Auditoriums, Convention Centers, Ballrooms, Catering Halls * Restaurants, Bars, Night Clubs * Data Centers * Hospitals and Laboratories
