The drive to reduce UK Carbon Emissions directly associated with dwellings and to achieve a zero carbon home dictates that Renewable Energy Technologies will have an increasingly large role in the built environment.  Created by the Building Research Establishment (BRE), the Standard Assessment Procedure (SAP) is the UK Government’s recommended method of assessing the energy ratings of dwellings.  This paper presents an evaluation of the advantage given to SAP ratings by the domestic installation of typical Photovoltaic (PV) and Solar Domestic Hot Water (SDHW) systems in the UK.

Holonic Energy Systems (HES) refer to systems where distributed generation and centralized powergeneration are organically combined to establish optimal operation, based on a good balance betweenthe whole and its parts, but not on optimization of each part that is the conventional concept ofupgrades in a single energy source. This paper presents an outline of HES proposed by us and threemicrogrid verification test results demonstrated through the activities toward HES. On the test results,reduction rates of CO2 emission of the microgrid operation was above 20% for reference system.

The present paper is a review on methods and technologies for air cleaning from micro organisms andviruses, which are applicable with the present HVAC practices. The advantages and the drawbacks ofair dilution, filtration (HEPA, ULPA), ultraviolet germicidal irradiation (UVGI), photocatalytic oxidation(PCO), plasmacluster ions and other technologies for air disinfection and purification is criticallyanalyzed with respect to the used today air distribution principles.
