Heated and Dehumidified Air

The museum uses two independent systems to maintain comfortable interiors - a radiant floor heating system to supply heat inside, and a dedicated outdoor air system (DOAS) to keep interior air clean and dehumidified. Dehumidification is particularly important here because of the artworks stored in the building and Riga’s proximity to the Baltic Sea. This is taken care of in the lower block (ground and first floors) by a ground floor based plant, while the air in the upper block is maintained by a plant on the roof.

HVAC Zones Spaces in the museum have been grouped together into zones based on their heating and humidity loads and levels desired. Zones can be controlled independently, and conditioned as appropriate for their use and occupancy. This allows for saving energy consumption in certain zones while maintaining the desired comfort levels in others.
