Modelling the energy resource for buildings and the use of appropriate low carbon technologies
Orateur : Aymeric Girard - Univ. Adolfo Ibañez, Chili
Abstract : My presentation will consist in the presentation of two independent studies on topics related to determining the availability of renewable sources on a particular site by increasing the efficiency of buildings through appropriate design.
The first part aims to develop a pioneering software tool allowing the assessment of possible energy sources for any building design project. The package allows the user to simulate the efficiency of the Passive Solar Space Heating referred in the Low and Zero Carbon Energy Sources (LZCES) Strategic Guide stated by the Office of the Deputy Prime Minister and the Building Regulations. This research presents the tool for modelling the passive solar sources availability in relation to low-carbon building. A 3-month experimental set up monitoring a solar house in West Lothian, Scotland (figure 1), was also undertaken to validate the simulation tool. Experimental and simulation results were found in good agreement following a one-to-one relationship demonstrating the ability of the newly developed tool to assess potential solar gain available for buildings. This modelling tool is highly valuable in consideration of the part L of the Building Regulations.
The second part aims to analyse the most suitable heat pump configuration for the military O’Higgins base in the Chilean Antarctic and the environmental impacts of the refrigerants used in this technology. Room conditions where the heat pump could possibly be installed were monitored, and a heat pump simulation was performed to determine the best location and the most optimum refrigerant to be used. Due to the low ambient temperatures at the base, the most effective location is actually inside the base, in a room with relatively elevated temperature. A one-year experimental set up monitoring a thermodynamic heat pump in Antarctic (figure 2), was also undertaken to validate the simulation tool.
