Passive building with high energy efficiency, Aloja, Latvia

Passive building with high energy efficiency

Aloja municipality is one of the first in Latvia which implemented low-energy building and used wood as a basic construction material in the construction of public building. Heat energy consumption during operation per heated area will not exceed 14.6 kWh / m2 per year.

Участие Uponor

The building is equipped with Uponor underfloor heating and cooling. There is no radiator in the building and in summer it is cooled by the floors. Smatrix automation is used for automatic system control.

Short description

Business Support Center - library SALA is intended for several functions. The building consists of three main functional blocks - a library, large seminar hall and study rooms. All the blocks are located on the only floor of the building. Each block has autonomous access.

The technical design of the building was developed in 2015, construction works began at the end of February 2016. The building has strip-shaped foundations, on which a slab 250 mm thick is supported, above which a thermal insulation layer 300 mm thick is built. The foundation exhibition took 2 months. A diverse range of materials was used in the construction of the building - concrete, wood, metal, etc. Wood is very widely used - both as a frame and as a finishing material. There are two reasons for this: firstly, great emphasis was placed on the use of natural materials, and secondly, it is with the special woodworking technique that the design concept can be achieved. Local materials were mostly preferred.

One of the characteristics of the building is the high energy efficiency of the building. To ensure this, the architectural solution of the building fully meets the energy consumption criteria of a passive building. The calculation was performed using the Passive House Planning Package program.

The heat source of the heating system and hot water supply uses a heat pump with geothermal heat supply from deep well probes. It is equipped with automation and control elements. There are no radiators in the building, nor does it have air conditioners. In summer, the building is cooled using floors.

The object can be assessed as relatively complex, because the goal was to build the building in accordance with the standards of passive construction. During the construction process, it required a much closer look at the construction of the units, the density of the constructions, controlling the quality at each stage of construction. The clay soil also complicated the construction of the drainage system planned for the project.

Day-care centre to be built with energy piles

As requested by the City of Vantaa, the Vaaralanpuisto day-care centre has been planned based on the "nearly 0 energy days" concept. Construction work for the day-care centre began in late summer 2016, and the project will be completed in July 2017. Project costs are estimated at EUR 5.4 million, and the day-care centre will accommodate about 130 children. Among the various energy production options available for the site, the City of Vantaa chose the energy pile and solar thermal collector system jointly developed by Uponor and Ruukki.

The New Deichmanske Library - Bjørvika, Oslo

Deichman is equipped with Thermally Active Building System - a system for storing the energy in the concrete ceiling. It is primarily a cooling system, but it can also be used as a heating system. When in cooling mode, no energy is used as the heat is drawn into the concrete, only when it is transferred from the concrete and into the water pipes that are cast in the decking. The need for installed power is reduced, and operating expenses are significantly reduced as opposed to in a air-based cooling system. The TABS is cast into the Prefab elements, which is a BubbleDeck construction with spans up to 10.5 meters.
