APPLICATION OF ENERGY RENEWAL PROJECT WITH EU-FUND CO-FINANCE (PROJECT IN PREPARATION)

After the co-owner's decision, we submitted the building "Mornarički trg 2 in Pula" to the tender for energy renovation of multi-apartment buildings NPOO.C7.2.I1.01.

The main goal of the energy renovation project of the apartment building at Mornarički trg 2 in Pula is to present the current state of the building and provide construction measures to improve the building's energy efficiency, which affect the improvement of conditions in the building for all users, as well as the reduction of heating and cooling costs.

The purpose of the building is residential. The residential building has a square floor plan. On the ground floor of the building there are storage rooms (unheated part), an apartment and a common area for the co-owners of the building.

The net area of ​​the heated part of the building is 1,438.27 m2, while the gross area of ​​the heated part is equal to 1,770.62 m2.

The outer envelope of the building consists of solid brick walls with a total thickness of d=40 cm, the walls are treated with lime-cement plaster on both sides. Thermal insulation was not installed on the external walls.

The walls towards the staircase are built with solid brick d=25cm, and are treated with lime-cement plaster on both sides. The floor on the ground of the heated and unheated space is made as a reinforced concrete slab on which a cement screed is placed, which is also the final layer. The flat roof of the building is a reinforced concrete slab, on top of which concrete is laid and waterproofing. There is no insulation on the roof. The entrance door to the building is PVC.

The building is heated locally. The apartments have a heating system based on air conditioning devices and thermoaccumulation stoves, and partly on solid and gaseous fuels (wood and gas).

The existing building is of energy class C, with an annual primary energy (Eprim) for heating with a starting value of 240,715.26 kWh/a. The target value after energy renovation would be (Eprim) = 118,690.66 kWh/a, which would be a contribution = -122,024.60 kWh/a or 50.69%.

Annual CO2 emission before energy renewal = 35,020.04 kg/year. annual CO2 emission after energy renovation = 17,267.50 kg/year. which is the contribution to the reduction of CO2 emissions= -17,752.54kg/year which is = 50.69%.

Frontage height up to 25 meters, ground floor and six floors.

The measures foreseen in this energy renovation project are: performing thermal insulation on the external walls by making the ETICS system according to the manufacturer's instructions, all preparations: stone mineral wool d=10cm for the walls bordering the heated space, stone mineral wool d=5cm for treating the chimney and ventilation, a view of the exit to the flat roof and stone mineral wool d=3cm for processing the slats around the windows.

Thermal insulation of a flat walk-through roof-terrace with hard stone mineral wool for flat roofs d=14cm, the thermal insulation must be installed in such a way that the drops are carried out towards the horizontal gutters, i.e. downspouts, which are located on the edge of the flat roof, i.e. the corners of the building.

The existing wooden joinery will be partially replaced in the common parts and in the apartments with new PVC joinery with an interrupted thermal bridge, sealed with all fashion pieces and PVC profiles that have the ability to collect and drain condensate With external protection from the sun (blinds), glazing will be carried out triple IZO glass with gas filling with low-e coating and triple sealing with a defined maximum heat transfer coefficient for the entire window Uw=1.10w/m2K, while the coefficient for the glass is equal to Ug=0.70W/m2k.

Carpentry installation should be carried out exclusively using the Ral installation method, where special sealing tapes are used, intended exclusively for this type of sealing. The color of the joinery is white. The slats will be processed and insulated with mineral wool d=2cm

After the implementation of the measures foreseen in the Main project of energy renovation of multi-apartment buildings, energy consumption will be significantly reduced and the energy class will be A, with predicted savings according to budget data from the main project.

The purpose of the energy renovation of the apartment building is to improve conditions in the building for all users, as well as to reduce maintenance and heating costs, as well as to reduce pollution and emissions of harmful CO2. The existing building was built in 1964, and has great potential for implementing energy efficiency measures that will be carried out in accordance with the Main Energy Renovation Project of the building at Mornarički trg 2, Pula. Currently, the building in its environment looks aesthetically disordered. Due to wear and tear, parts of the facade plaster occasionally fall off the balcony and facade, which poses a danger to people and vehicles. For this reason, warning boards have been placed on the building for a long time.

The share of energy from renewable sources in the annual delivered energy before energy renewal, initial value: = 49.08%. Share of energy from renewable sources in the annual delivered energy after energy renewal, target value: = 29.84%.

Increase in the share of energy from renewable sources in the annual delivered energy, contribution: = -19.24%.

Existing condition of the building:

Currently, the building, according to budgets, has a high energy consumption and emits a large amount of CO2.

Annual CO2 emission before energy renewal = 35,020.04 kg/year. annual CO2 emission after energy renovation = 17,267.50 kg/year. which is the contribution of reducing CO2 emissions= -17,752.54kg/year which is = 50.69%

The roof is not thermally insulated.

The building envelope does not have any thermal insulation, which causes large energy losses when heating/cooling the space.

The carpentry of the building is mostly wooden and due to the time limit, it has become permeable.

Due to the current state of the facade and roof, leaks, moisture, condensate and muff appear in the heated spaces, which makes the residential microlocation unhealthy and uncomfortable.

The purpose of the building is residential. The residential building has a square floor plan. There are storage rooms on the ground floor of the building (unheated part).

The outer envelope of the building consists of solid brick walls with a total thickness of d=40 cm, the walls are treated with lime-cement plaster on both sides. Thermal insulation was not installed on the external walls.

The walls towards the staircase are built with solid brick d=25cm, and are treated with lime-cement plaster on both sides. The floor on the ground of the heated and unheated space is made as a reinforced concrete slab on which a cement screed is placed, which is also the final layer. The flat roof of the building is a reinforced concrete slab, on top of which concrete is laid and waterproofing. There is no insulation on the roof. The entrance door to the building is PVC.
