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.

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.
