+ | ====== Example: Overall power provision for a Passive House ====== | ||
+ | |||
+ | A Passive House single-family home was used to simulate a renewable supply structure with the method described in the previous section. Figure 1 shows primary power generation for a mix of 60 percent photovoltaics (PV) and 40 percent wind energy (wind) in the TRY12 (Oberrheingraben) region from January 17 to February 4. Production is clearly irregular, with PV providing almost 1, | ||
+ | |||
+ | Figure 2 depicts power demand in this four-person Passive House home over the same time period (top curve). As usual, energy is taken from the grid for normal household appliances (fully equipped), cooking, and lighting. However, all devices in question are highly efficient, with the current market' | ||

+ | Since, however, a significant share of power demand can be covered by primary power generators and a similar share can come from mid-term grid storage (with an efficiency of more than 70 percent, much higher than the P2G system), the average renewable primary power expenditure over all applications PER< | ||
