• Development and optimization of highly efficient heat recoveries for low carbon residential buildings 

      Liu, Peng; Justo Alonso, Maria; Mathisen, Hans Martin; Halfvardsson, Anneli (Peer reviewed; Journal article, 2022)
      To achieve energy efficiency and lower carbon emissions, building envelopes have become tighter and more insulated. These buildings must have mechanical ventilation with high efficient heat recovery to provide adequate ...
    • Evaluation of low-cost formaldehyde sensors calibration 

      Justo Alonso, Maria; Madsen, Henrik; Liu, Peng; Jørgensen, Rikke Bramming; Jørgensen, Thomas Berg; Christiansen, Even Johan; Myrvang, Olav Aleksander; Bastien, Diane; Mathisen, Hans Martin (Peer reviewed; Journal article, 2022)
      Low-cost sensors (LCS) are becoming ubiquitous in the market; however, calibration is needed before reliable use. An evaluation of the calibration of eight identical pre-calibrated formaldehyde LCS is presented here. The ...
