Indoor Environmental Quality in Mechanically Ventilated, Energy-Efficient Buildings vs. Conventional Buildings
Energy-efficient buildings need mechanical ventilation. However, there are concerns that inadequate mechanical ventilation may lead to impaired indoor air quality. Using a semi-experimental field study, we investigated if exposure of occupants of two types of buildings (mechanical vs. natural ventilation) differs with regard to indoor air pollutants and climate factors. We investigated living a...
متن کاملIndoor Air Quality of Office Buildings in the Helsinki Area
Indoor air quality (IAQ) was investigated in 19 open-plan offices and 30 office rooms in order to compare the differences in these two different types of office environments. No moisture or mold problems had been reported from the present buildings, but the employees had complained about the IAQ. The results revealed only slight differences in the IAQ of the two different types of office enviro...

متن کاملA Dual Airflow Window for Indoor Air Quality Improvement and Energy Conservation in Buildings
This paper proposes a novel dual airflow window for use in residential buildings that tempers outdoor air with exhausted indoor air. The energy needed to condition outdoor air is reduced because of the counterflow heat exchange between the two flow streams. Experimentally validated computational fluid dynamics (CFD) simulations have been used to optimize the window design and to estimate the be...
متن کاملAn Indoor Positioning System Based on Wi-Fi for Energy Management in Smart Buildings
To offer indoor services to occupants in the context of smart buildings, it is necessary to consider information concerning to the identity and location of the occupants. This paper proposes an indoor positioning system (IPS) based on Wi-Fi fingerprint and K-nearest neighbors (KNN) method. The positioning of a mobile device (MD) using Wi-Fi technology involves online and offline phases. In this...
