In the first step of engagement with a client,  PURE will ask for the specifications of the units (AHU/Cooling Tower/Dry Cooler). These specifications will help PURE assess whether there is any potential for significant energy efficiency gains for the client.

Based on the unit specifications, PURE will issue a brief report to the client stating the energy efficiency gains and whether the project is recommended or not.

If the theoretical calculations show a strong potential, in agreement with our client we move on to the second step - the Site Survey. Here we mobilize on site and survey each unit that needs to be decarbonized. We measure aspects such as:

• Unit cross sectional area

• Power consumption of old belt driven fans

• Unit Air Flow

• Pressure

Based on these measurements, PURE will issue a brief report indicating the project price and the return on investment (or investment payback period). 

To demonstrate the reliability of our calculations and workmanship of our solutions, PURE proposes a pilot project that generally consists of 4 to 6 units in case of AHU. We propose a 3 month monitoring period of the Pilot Project to witness:

• Unit power consumption

• Unit performance (airlfow, etc.)

Once the Pilot Project has been validated and shown to be reliable, we move on to the last step of the process which generally consists of decarbonizing one or multiple buildings or assets as part of a sport contract or frame agreement.

PURE Talotekniikka Global calculates the reduction in CO2 emissions as a result of the modernization project. Our Client must indicate the electricity supply technology (coal, nuclear, geothermal, hydropower, etc.).

Using the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC) median values for CO2 emissions, PURE will calculate the annual CO2 emissions reduction as a result of energy efficiency gains.
