The significance of Energy Auditing and Certification.

In the coming years, the energy certificate will become increasingly important as an "information package" when discussing or comparing the energy efficiency of a building, especially when buying or selling a property, building, or share.
According to the proposal of the European Parliament, residential buildings should achieve a minimum energy efficiency class E by 2030 and energy efficiency class D by 2033.

A properly made energy certificate serves as a valuable tool for sellers, buyers, real estate agents, as well as property owners and residents.

The energy certificate indicates the energy class of the building from A to G. The energy classification is determined based on the E-value of the building, which comprises the calculated annual purchased energy consumption of the building, weighted by coefficients for different energy sources per square meter. The E-value includes, for example, heating, cooling, ventilation, hot water heating, lighting, and the energy requirements of consumer appliances.

The energy class can be improved by reducing the energy consumption of the house, for example by improving the insulation of the house, by additionally insulating the attic. The significance of building technology on a construction’s energy efficiency cannot be overstated. The utilization of solar electricity and solar thermal energy also enhances the energy efficiency and classification of a house.

Examples of CO2.fi Ltd.'s projects

The ARA has granted energy grants to the mentioned targets.

ARA has supported energy efficiency improvement renovation projects in 2023 with nearly 100 million euros. Here are examples of targets on which CO2.fi Ltd. Markku Elg applied for energy grants..

Agricultural farm in Pornainen

Background: the objective is to convert the existing oil heating system in the premises into an air-to-water heat pump system. A solar energy system (approximately 60 panels) was installed in the agricultural facility to generate additional energy.
Actions taken: Markku Elg from CO2.fi generated E-calculations and designed a solar power system. The property was inspected on-site, and subsidy applications for energy assistance were prepared for the residential building regarding the Ara subsidy program. Additionally, a grant application for agricultural buildings was submitted to the ELY Center. New energy certificate for the payment to ARA. The agricultural entrepreneur implemented the measures. The agricultural entrepreneur implemented the measures. According to calculations, ARA granted a subsidy amounting to 4,000,-.

Apartment building company in Kulosaari

Background: The company implemented significant energy-efficient solutions, such as two geothermal heat pumps, a new heat recovery system, and the replacement of windows and doors. Additionally, the balcony glazing was renewed.
Actions taken: Markku Elg from CO2.fi compiled E-readout calculations for the building. The property was inspected on-site and an energy grant application was prepared for ARA. New energy certificate for the payment to ARA. The company implemented the measures. According to calculations, ARA granted a subsidy amounting over 146.000,-.

Terraced house company in Järvenpää
(8 apartments)

Background: The increase in district heating prices was significant, so the company wanted to become more self-sufficient. We switched to a ground source heat pump system. Additionally, an solar power system was installed to support the geothermal system and its electricity consumption.
Actions taken: Markku Elg from CO2.fi compiled the E-number calculations, and an energy grant application was made to ARA. New energy certificate for the payment to ARA. The company implemented the measures. According to calculations, ARA granted a subsidy amounting 70.000,-.

Apartment building company in Kouvola

Background: The company had a natural gas system and made a transition to an air-source heat pump system.
Actions taken: Markku Elg from CO2.fi compiled the E-number calculations. The property was inspected on-site and an energy grant application was prepared for ARA. The company implemented the measures.
The company has received a positive decision amounting to 64,000,-

The single-family house in Järvenpää

Background: The single-family house was equipped with oil heating (built in 1954), which provided heating for the premises as well as hot water. We wanted to switch to cleaner and more energy-efficient heating. The solution chosen was a ground source heat pump, and the ventilation system was completely renewed with Valox 145 MV. Additionally, the windows and doors were replaced.
Actions taken: Markku Elg from CO2.fi compiled the E-number calculations, and an energy grant application was made to ARA and updated the energy certificate for payment to ARA. The measures were implemented.
According to calculations, ARA granted a subsidy of 6,000 (maximum amount for the single-family house).
