Reports and forecasts for heat and cooling consumption

Usage and forecast data for heating and cooling are always available when needed in Oma Helen or Yritys Helen. By logging in and selecting Heating or Cooling, you can access updated reports on your property’s district heating or district cooling, even down to hourly detail.

Reports are continuously refined as new information becomes available. New energy prices are published at the end of May and November, and at the same time, energy price forecasts can also be adjusted. The price list and principles for the district heating basic charge are updated once a year and take effect at the beginning of July.
Reports and price information are no longer sent by post – this ensures fast and environmentally friendly access to information for all our customers.

Monitoring energy consumption is the starting point for efficient energy use!

Energy consumption varies from year to year depending on weather conditions, even if the use of the heating site has otherwise remained completely unchanged. Normalized consumption is comparable regardless of temperature differences between months or years! In Oma Helen and Yritys Helen, you can view both the actual and normalized consumption of your property.

Helen’s normalization calculation method is based on Motiva’s guidelines. The key principles are:

• The energy required to heat domestic hot water does not depend on outdoor temperature and is therefore excluded from normalization. The share of hot water is estimated based on the average heat consumption during June–August of the previous year.
• If heat usage started between June and December, normalization is not applied for the first year.
• Normalization is done on a monthly basis, and exceptional summer months are excluded from the calculation. Consumption during these months is not normalized.
• More precise normalization of building heating energy is possible if the measured energy for heating domestic hot water or total water consumption is known. These details are available from property-specific energy metering data or, for example, from the water bill. Detailed normalization and network-specific energy analysis are recommended if renovation or energy efficiency measures are planned for the building.

More information and instructions on normalization can be found on  Motiva's website (in Finnish). 

Building energy efficiency and energy use can be compared using specific consumption. In Oma Helen and Yritys Helen, you can see the specific consumption for your property and building type, both based on invoiced and weather-corrected district heating energy.

The specific consumption of a building is calculated by dividing energy consumption by the heated/cooled volume. The building-type-specific consumption is the average specific consumption of buildings of the same type. For apartment buildings and offices, building-type-specific district heating consumption is calculated so that the comparison group consists of buildings constructed in the same decade, provided there are more than 10.

Comparison works best for building types with many buildings and similar usage patterns. Differences between buildings, such as energy efficiency measures or technical changes over the years, are not considered in the comparison.

Energy and basic charge forecasts provide a clear estimate of upcoming monthly costs – helping you stay one step ahead and plan your finances with confidence! Principles for forecast calculation:

• The forecast for district heating energy consumption is based on normalized consumption. Each month’s forecast is the average of the previous three corresponding months’ normalized consumption.
• The forecast for district cooling energy consumption is based on invoiced consumption. Each month’s forecast is the average of the previous three corresponding months’ invoiced consumption.
• The forecast for energy charges is the product of the energy consumption forecast and the energy price forecast.
• For all forecasted months, the latest invoiced basic charge amount is used as the forecast for basic charges.
