Half-hourly data HHD
Half-hourly data (HHD) also just referred to as Half Hourly (HH) is normally used in relation to energy use, metering or in connection with post occupancy evaluation, energy monitoring or auditing. It simply means that the measuring device can record the amount of energy used in every half-hour period and is normally a function that is offered by modern smart energy meters.
There are a number of potential benefits of tracking energy use every half hour:
- Half hour periods can help in determining cases when and therefore where excess energy is being used.
- Half hour periods can help determine specific times of a day when higher energy is used.
- Half hour period measuring communicated with suppliers can allow them to offer time-of-use energy tariffs that charge less for energy when demand is low.
- Half hour period measuring can help energy suppliers and the grid in managing energy demand and supply as well as predicting high and low use periods.
Half hour data for energy use is increasingly a requirement of energy companies and is supported by government policy through the installation of smart meters.
