Uppsala kommun has acquired the land at Ulleråkerand the plan is that it should be the starting point forthe new southeast district. The area is supposed toinclude 8000 new homes. The idea is also that the areashould be a new modern energy-efficient district. Thisreport examines how much energy that could be savedby using a passive house integrated design instead oftodays standard. Simulations in Matlab regarding localenergy utilization has also been done. Calculationsshow that the passive house integrated designgenerates in a total energy saving of 49 per centcompared to the standard house. The local electricalproduction comes from solar cell panels placed on theroofs and facades and the installed power is 19.8 MW.The production covers 80.3 per cent of the totalenergy demand or 91.4 per cent of the electricaldemand per year. But the systems production ismismatched to the local demand for electricity.
