Energy check-up
Energy efficiency
Video from Ilmastoinfo YouTube channel.
- Energy check-up of a housing company is a concept developed by Finnish Motiva, consisting of six sections:
- 1. Inspection of heat distribution or boiler room equipment:
- Heat distribution room (LJH) sub-center: (1) Performance evaluation, (2) Possible need for renewal, (3) Cleanliness
- Checking the layouts of the adjustment curves and evaluating the possible need for changes
- Functional tests of district heating control valves: Closing the valve motors and checking that there is no flow through the valves
- Ensuring the tightness of the operational condition of the district heat exchangers (that there are no leaks in the plate heat exchangers)
- Evaluating the pre-pressures of the expansion vessels and ensuring a sufficient pre-pressure in relation to the needs of the property
- Ensuring the correctness of the alarm limits and defining the correct pressure levels of the heating and domestic water networks
- Operation and condition of the pumps
- District heating water cooling
- Checking the functioning of the meters
- In oil heating sites, flue gas analysis of the boiler in operation.
- 2. Inspection of the operation of the heat distribution network in the public areas of the property and in at least two apartments on different sides of the building:
- Operation of radiator thermostats and valves
- Measuring the internal temperature.
- 3. Checking the functioning of the ventilation system:
- Correspondence of the visiting hours to the property's operating hours for facilities and service areas
- Checking the forced connections based on the operation diagram: (1) Closing and operation of damper motors, (2) Operation/stopping of fans, (3) Ensuring the operation of the heating coil's frost protection
- Operation of the control valve of the post-heating coil
- General cleanliness of IV machines, cleanliness of filters and types of filters
- Condition of fans and possible need for bearings, checking V-belt drives (if any)
- Heat recovery: (1) Heat recovery efficiency, (2) Operation of heat recovery dampers In buildings with an apartment-specific ventilation machine, the inspection is performed on at least two IV machines.
- 4. Water:
- Checking the pressure level of the water supply network and the hot domestic water as well as the return temperature of the circulation.
- Find out the need for the use of a pressure relief valve.
- 5. Energy and water consumption:
- Heat, electricity and water consumption levels and trends, as well as a comparison with the consumption level of similar properties (for example RT 103003 Residential property condition assessment, condition assessor instructions).
- 6. Checking the operation of lighting in public spaces:
- Lighting controls and appropriateness.
- What is the magnitude of lighting's share of the property's total electricity consumption (courtyard and general areas of the property).
- Technical lifespan of the lighting.
- Is LED lighting suitable for the current lamps or is it worth completely renovating the lighting system.

- Energy check-up reporting:
- Making comments on observed defects and deficiencies
- Procedure presentations (operational technical measures and investments)
- Recommended additional clarification needs regarding measures that the Building Company probably has potential opportunities to improve energy efficiency, but which require additional clarification: (1) Alternative heating systems and an assessment of their profitability, including geothermal heat, PILP, air-water heat pump, solar heat and electricity, waste water heat recovery, (2) Intelligent regulation and control and elasticity of demand, (3) Structural energy efficiency possibilities (top floor, windows, doors, facade)
- Indicative assessment of the housing association's possibility to use the energy subsidy (based on the building's original heating method and the renovations carried out). Note: does not include the calculations needed to apply for the subsidy.
- Providers are asked in the offer if following criteria are fulfilled:
- Those carrying out the survey must have an engineering training in the field of HVAC or equivalent knowledge.
- The bidder's service covers at least the minimum content of Motiva energy check-up specification. Read more here:
