Construction specs Tiiu 14

Energy class

The energy efficiency figures on which the calculation of the energy class of the Tiiu 14 buildings was based equate to a A rating. The Tiiu 14/1 building will comprise three sections, of eight, five and five storeys respectively. There will be a total of 63 apartments in the 14/1 building.

Building structures

The load-bearing framework of the below-ground levels of the apartment buildings will be poured monolithic reinforced concrete posts, beams and walls and the monolithic inserted ceiling linking them. Triple-layered reinforced concrete elements will serve as the load-bearing framework of the above-ground levels. To ensure greater sound insulation, the inserted ceilings are to be made from 265 mm hollow and solid reinforced concrete panels.

Internal walls, stairwells & corridors

The apartments will feature plasterboard walls on a metal framework between rooms, while the walls around bathrooms will be assembled from lightweight blocks. To ensure greater sound insulation, the walls between apartments will be made from 200 mm reinforced concrete panels. There will be three stairwells with lifts in each building.

Loggias & terraces

Almost all of the apartments will come with a loggia featuring glass railings below and opening glass panels above. All of the apartments on the 1st floors of the buildings will have their own terrace with timber decking.

Doors & windows

The apartments will have triple-glazed windows with timber and aluminium frames and fireproof wooden veneer external doors. The height of internal and external doors will be 230 cm on the top and bottom floors and 210 cm on other floors.

Ceiling height

The ceiling height in the living areas of the apartments will be ~2.9 m. The apartments on the top (8th) floor of the building will be more spacious again, with a ceiling height of ~3.2 m.

Heating & interior climate

The buildings will be connected to the central heating system. Water-based floor heating which can be adjusted in every room will ensure an energy-efficient interior climate. Internal air quality will be guaranteed using apartment-based rotary heat-recovery forced ventilation. The ventilation equipment will be kept out of sight behind the inserted ceiling in the bathroom or, in larger apartments, in the laundry. The kitchens will be prepped (i.e. provided with the piping and cabling required) for the installation of a motorised rangehood. The extraction pipe for the rangehood will have a backflow valve with an electric drive installed so as to avoid noise being generated in the pipes during windy periods when the device is not in use.

Cooling

All four- and five-room apartments come with a cooling unit installed, the cost of which is included in the apartment price. Preparations will be made in the two- and three-room apartments for the installation of a cooling unit, which the client can purchase from us at additional cost. Alternatively, the client can install their own cooling device at a later point.

Smart buildings

All of the apartments are to be constructed according to the principle of ‘smart buildings’, which means that internal climate, intercom and the reading of meters will be automated. The standard ‘smart building’ installation for apartments includes heating and ventilation controls, an intercom system with picture and sound and the reading of electricity and hot and cold water meters. Readings will be automatically forwarded to the building manager. All of the foregoing will be able to be managed and monitored online or via the touch screen in the apartment.

Water supply & sewerage system

The buildings will be connected to Tallinn’s water supply and sewerage system. Hot water for the buildings will be generated by a central heating node in the basement. Water meters will be read remotely. Readings will be taken automatically and forwarded to the building manager’s database.

Electricity & weak-current systems

Remotely read electricity meters will be located in power rooms on the underground level. The distribution board in most apartments will be located in a niche in the entryway wardrobe; in larger apartments it will be situated in the laundry. The board will be prepped for connection to the security centre. There will be communications connections and a free space for a router and other active computer network devices. Technical preparations will be in place for telephone, Internet and TV service contracts to be entered into with service providers.

Light switches and power points will be found in the apartments in the locations selected by the interior architect. Rooms with inserted ceilings will feature recessed lighting, while the terraces and loggias will have lighting and power points suited to outdoor conditions.

Charging of electric cars and light vehicles

All storage spaces will feature a charging point whose use can be measured separately to charge electric scooters. Parking spaces will be prepped for charging points for electric cars. The buildings will be fitted with a central device with a dynamic load meter, measuring use for the entire building and directing unused and available capacity to the chargers. Personal charging stations will be able to be purchased or rented from the service provider.

Underground level

The underground level will not only be home to personal parking spaces, storage areas and technical rooms, but also bicycle storage, upkeep and cleaning rooms for the use of all residents. There will also be a table for waxing skis. The walls on this level will be adorned with graphics.

1st floor

The 1st floors of the buildings will feature a room accessible from both the street and the foyer for the storage of bicycles and baby carriages. A waste room will also be situated on the 1st floor, next to the ramp.

Courtyard area

Adding a touch of privacy to the terraces on the 1st floor will be planting pots and greenery supported by a raised wall.

The sloped roof above the ramp extending into the courtyard will be able to be walked on and will feature partial landscaping. The permanent greenery in the community garden will feature trees and bushes producing edible fruit and berries, while support walls will enable planting both within the garden and around its perimeter.

There will be different play areas in the courtyard, primarily designed for little children: one featuring water; another with sand; a large sloped area with child-friendly rubber surfacing; and rocks for climbing on. Rainwater in the courtyard will be channelled into a stone-bottomed hollow with landscaped slopes, providing a fun and eye-catching natural space to play in.

Accessibility

Step-free access will be provided at all building entry points, making them easy to use for residents and visitors with restricted movement and vital for those in wheelchairs or pushing baby carriages. The common areas in the buildings will feature contactless Bluetooth-based access systems.
