Energieffektivisering i ridanläggningen i Råneå

Abstract

If you want to minimize the need for purchased energy the best way is to ensure that as little heat and air as possible escapes from the building. A significant amount of heat in buildings with normal standard is lost through the surrounding envelope that is through the roof walls, windows, doors and floors. High air tightness of a building improves profitability by creating a better indoor environment and lower energy consumption. It normally requires addition of energy to balance the energy losses of various kinds. A building's energy is the energy that is purchased for normal use during a normal property and energy. For the building to be in balance have the energy to be equal to the losses.Transmission losses for the arena is approximately 140 000 kWh and for the stable approximately 130 000 kWh. Ventilation losses for the arena are approximately 140 000 kWh and for the stable 130 000 kWh.The energy consumption for the entire horse riding centre was approximately 340 100 kWh (2011). Heat consumption is approximately 270 200 kWh. When you subtract the unnecessary losses the consumption is approximately 170 000 kWh. Heat for the buildings are obtained through under floor heating, (not in the riding hall) heated by an electric cartridge of 9 kW and electric air heaters, staff areas are heated by electric radiators. Domestic hot water is prepared in electric water heaters. Heat recovery on ventilation is in the staff areas. The stall has an FT system with a central exhaust and two supply fan.I have developed a number of suggestions for improvement comprising: Improve / replace existing insulation. Replace existing heater poles for cars, to time-controlled. Replace the interior lighting in the riding hall to motion sensor lighting. Have the outdoor lights turned off during certain times of day. Lower the heat to radiators in those areas that are not directly used like coffee room / kitchen and keep the gates closed, Replace the existing radiators to more energy efficient ones. Replace existing heating system to geothermal heating, wind power, combustion of horse manure (Sewbo Bio Therm boiler). I have also made financial calculations.Validerat; 20140207 (global_studentproject_submitter
