Article by Francesco Errico, Markus Kalo and Michele de Carli and myself was published in the REHVA Journal 1/2016. The article is about “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).
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.
