The procurement is the subject of a contract with one supplier.
A large part of TVT Asunnot Oy's residential building projects still use a traditional temperature control solution without smarter optimization, for example. based on weather forecasts or data measured from apartments. The aim of the procurement is to install apartment-specific temperature and humidity sensors in these locations and to connect the sites to a more intelligent heat control circuit.
This invitation to tender invites prices for the following packages:
1) Wireless apartment sensor installed (eur/apartment)
2) Measurement data management service (eur/month/apartment)
3) Heating regulator installed (eur/regulator)
4) Intelligent control for heating controller service (eur/month/apartment)
The requirements for equipment and services are defined in Annex 1 to the call for tenders.
The scope of the acquisition is approximately 3,000 to 6,000 apartments. The sites are identified and the exact number of sites and apartments is decided after competitive tendering. Apartment sensors are installed in all apartments of selected residential buildings. The equipment must be installed in 3,000 apartments by the beginning of the 2023 heating season. For these apartments, the solution must be in working order by the beginning of the 2023 heating season.
The most common single heating controller model in TVT Asunnot Oy's residential buildings is the Danfoss ECL Comfort 310. Some of the sites use older control models. Heating regulators are replaced in those places where it is not possible to connect the old regulator to a more intelligent control. The number of switchable controllers will become clear after competitive bidding.
The basis for comparing the overall economic advantage of tenders is the price. From the offers received, the cheapest in terms of price is selected.
