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
