Swegon Air Academy Case Study Engelsons in Falkenberg was updated with a new article about effects of different heat and cold generation scenario in DCV and VAV systems!

Engelsons in Falkenberg, built in 2009, is an office-retail building with VAV system with air and water. The building is used as offices, a warehouse and a store with packing area. This building case study was updated with a new article on “Effects of different heat and cold generation scenario (Heat pump versus district heating and chiller) in a building with variable air volume versus demand controlled ventilation systems” (link to the article) by Francesco Errico, Markus Kalo, Michele de Carli and Petra Vladykova Bednarova published in the REHVA Journal 1/2016.

The objective is to verify the operation of an installed system in an Office Retail building located in Sweden. The focus is on comparing the energy saving achievable with different ventilation systems with focus on keeping or improving the indoor comfort condition. The systems taken into account are: a constant air volume, a variable air volume and a demand controlled ventilation system. The energy saving is analysed considering two different heat & cold generation scenarios (heat pump versus district heating and chiller) in order to make the evaluation in terms of purchased energy and economy. The findings show the importance of continuous monitoring, the advantages of the choice of an advanced ventilation system and the importance of the chosen generation systems considering energy and economical costs.
