ABSTRACT
The energy consumption of power sockets, mechanical ventilation with heat recovery (MVHR), cooking, lighting and miscellaneous loads was monitored by submeters for an initial period of two years. Lark Rise was designed to demonstrate how advanced-technology housing can provide heating and all other household needs including purification of its own waste products, while at the same time releasing existing grid electricity capacity and exporting excess energy to contribute to the growing demand for electricity for other uses. The ventilation system’s actual consumption is 9 percentage of the total energy use at Lark Rise, which is twice as much as the 4 percentage calculated in the Passive House Planning Package (PHPP). While Lark Rise shows how much useful data can be extracted by the simplest of means the recording and processing of the data is timeconsuming and hence can be costly in terms of labour.
