The project involves a study, assessing the feasibility of several measures related to RES throughout the Adazi district. One of the issues is the deployment of RES in Carnikava parish, with the current 14 gas boiler houses to be replaced with a centralized system using RES. In the village of Kadaga, (population of around 2200), the aim is to justify the introduction of RES in the already existing district heating system.
The measure “Promotion of the use of renewable energy resources in district heating” will be the subject of an application for credit from the European Investment Bank. Both the municipality and heating operators and the population will be able to obtain an economic justification for the efficiency and benefits of the deployment of RES.
Measures foreseen are the deep retrofit of public buildings such as insulation, replacement of the ventilation system, replacement of doors and windows, replacement of the heating supply system and LED lighting. In addition, the aim is to also develop a solar park, with 5400 new PV panels, reconversion of DH boilers from natural gas to wood chip and the replacement of more than 8 000 public street lights from mercury vapour and high-pressure sodium-vapour technology to LED.
In conformity with the new EIB energy lending policy, the Riga will finance deep retrofit projects aimed to improve the energy performance of existing residential buildings. Riga will work as a revolving fund to finance deep retrofit of multi-apartment buildings and promote the formation of energy communities implementing RES solutions. Deep retrofit projects will include at least the following EE measures:
- insulation of the attic or roof, façades, slab on ground or basement ceiling
- replacement of the doors and windows
- installation of smart ventilation solutions
- modernisation of district heating system and district hot water system, installation of individual smart heat meters
- installation of decentralized RES solutions such as solar panels, heat pumps and others.
There will be other measures not directly connected to EE but needed to ensure the good technical condition of the building, such as the renovation of cold-water supply and replacement of roof coverin
Tukums intends to reduce heat energy consumption by 40% and electricity by 30% in 10 buildings. It is planned to ensure comprehensive reconstruction of the selected public municipal buildings, which will ensure a significant reduction of energy usage in the buildings. These measures usually include insulation of the building façade, refurbishment of the heating and hot water systems, change of windows, insulation of roof and basement, installation of solar PV panels and other measures.
In the case of the Ice Hall, technical measures would be the installation of a new freezing system and heat recovery system, replacement of the lighting, installation of solar PV panels, construction of a snow melting pit, installation of a new ventilation system and renovation of the building. These measures are crucial as these buildings consume a lot of energy and have not been refurbished since their construction (20-30 years).
