Energy efficiency in renovation projects
Almost all renovations in a housing company will also affect the energy efficiency of the building. This page provides you with opportunities to improve your housing company’s energy efficiency and energy self-sufficiency in the context of various renovations. It is best to prepare for some of these measures during major renovations, even if they are to be carried out later.
- Installing or commissioning an exhaust air heat recovery system
- Preparing for increasing the capacity of the electrical connection
- Electrical works, cable installations, information networks and preparing for these
- Water-saving plumbing fixtures
- Installing a pressure-reducing valve
- Heat recovery from wastewater
- Balancing and flushing the heating system
- Replacing radiator valves
- Smart heating and ventilation control
- Installing geothermal heating and cooling
- Solar collectors and panels
- A good time to consider switching to a heat pump solution is when you need to replace your district heating distribution centre
- Abandoning oil heating and switching to a heat pump solution
- Geothermal, exhaust air, and air-to-water heat pump solutions
- Solar collectors
- Solar panels to generate the electricity needed for a heat pump, for example
- Balancing the heating system
- Flushing the heating system
- Pressure-reducing valve for water
- Smart heating and ventilation control
- Cooling system
- Geothermal cooling together with geothermal heating prolongs the life of geothermal wells
- Heat recovery from wastewater
- Heat recovery, exhaust air heat pump
- Replacing fans with more energy-efficient ones
- Smart ventilation control
- Mechanical supply and exhaust ventilation with heat recovery (for individual units or centralised)
- Ventilation renovation with an external module and decommissioning of the old system
- If the housing company aims to switch to geothermal heating, yard renovations should be done after the geothermal renovation (yard excavations, landscaping)
- Charging points for electric vehicles (cabling and ground works before or during yard renovations)
- LED yard lighting
- Smart yard lighting control
- Checking the timer controls for de-icing and heat trace systems
- Smart heating control, smart thermostats
- Automation, control, monitoring and regulating systems
- Smart ventilation control
- Replacing and adjusting temperature and ventilation control equipment
- Checking the timers in the building’s sauna
- Lighting control
- Motion sensors, LED lights, dimmer switches
- Alarms (e.g. water leaks)
- Energy meters pinpoint consumption
- Temperature meter, electricity meter, water meter
- Solar panels or collectors after replacing the roof
- Additional insulation of the roof, attic or loft space
- In some cases, the load-bearing capacity of the roof must be taken into account for heat recovery systems
- Thermometers, electricity meters, water meters
- Additional insulation, thermal plastering, thermal imaging, air tightness testing
- Glazing balconies
- Solar panels for facades
- Energy-efficient windows and doors: The lower the U-value, the more energy-efficient it is
- Window renovation/seal maintenance, correct installation
- Supply air vents
- Sun protection for windows
- Thermal imaging, air tightness measurement
- Inspecting the condition of the foundation walls, additional insulation, adding frost insulation
- Adding cable or pipe ducts for energy-efficient equipment and systems
- Thermal imaging, air tightness measurement

Pay attention to preparedness
Preparedness measures, aimed at mitigating the impact of extreme weather events and improving the housing company’s sustainability, should also be included in repair projects. Some of these measures will also improve the energy efficiency of the housing company. See what measures you can combine with renovation projects.
