  • Publication number: 20080014857
    Abstract: A building's Heating Ventilating and Air Conditioning (HVAC) system is made more energy efficient and the indoor air quality (IAQ) of the building's circulating air is improved by incorporating a greenhouse as an integral part of the HVAC system and by utilizing a novel feed forward control strategy that maintains the proper levels of temperature, humidity and CO2 concentration in the building under varying conditions of day, time, use and occupancy. A portion or all of the exhaust air from the building is discharged into a greenhouse where the heat and humidity are recovered in the winter by heating the greenhouse and the air conditioning is recovered in the summer by cooling the greenhouse. Selected plants are used in the greenhouse to remove CO2 and pollutants from the building's exhaust air while enriching the air with oxygen and beneficial negatively charged ions.

  • Patent number: 6013771
    Abstract: A process for providing an isoflavone rich protein isolate is provided, along with the isoflavone rich protein isolate produced thereby. A vegetable material containing protein and at least one isoflavone compound is extracted with an aqueous extractant having a pH above the isoelectric point of the protein, and preferably an alkaline pH. The protein and isoflavones are extracted into the extractant, and the extractant containing the protein and isoflavones is separated from insoluble vegetable protein materials to form a protein extract. The pH of the protein extract is adjusted to about the isoelectric point of the protein to precipitate the protein. The extract containing the precipitated protein is cooled to a temperature of about 40.degree. F. to about 80.degree. F., and then the protein is separated from the extract. Washing of the separated protein is avoided, or, is conducted with minimum amounts of water.
