Efficiency of recirculation hoods

Recirculation hoods equipped with carbon and plasma filters are becoming more and more popular. The aim of this study is to determine the effectiveness of recirculation hoods with regard to PM2.5 and NOx removal in a 26 m3 lab kitchen with a gas furnace. With the carbon filter PM2.5 is reduced for about 30%. A fresh carbon filter removed about 60% of the NO2, dropping within a few weeks of cooking to 20%. With the plasma hood NO2 concentrations were above the WHO 1-hour limit and the Dutch health council 15 minutes limit.

Methodology for assessing the air-exchange performance of residential ventilation systems

Residential ventilation standards, especially in Europe are slowly but substantially moving away from their usual prescriptive approach towards performance based specifications. While academics and policy makers argue about the relevant IAQ indicators, housing developers and end users need to make a choice between the different ventilation system options they are faced with in the market. Although several IAQ rating systems have emerged, a comprehensive assessment method to rate the inherent qualities of the ventilation system itself is not available [6].

Technologies to overcome effects of condensation in exchangers of ventilation units - analysis of monitored field studies

Balanced ventilation with heat recovery is an efficient way to maintain low heating demand for ventilation in residential buildings. Laboratory measurements of today’s heat recovery ventilation units show high temperature recovery efficiency during standard conditions. In practice, however, the recovery efficiency may decrease due to circumstances that deviate from the standard laboratory conditions.

18-20 May 2015, Conference, Eindhoven, The Netherlands - Healthy Buildings 2015 - Europe

The Healthy Buildings 2015 Europe Conference will be held in Eindhoven, The Netherlands on May 18-20, 2015. 

Healthy Buildings 2015 Europe is organised by ISIAQ.nl and the Eindhoven University of Technology, under the auspices of ISIAQ International. 

The conference is built around six themes with two subthemes each related to the indoor environment as follows:

Design & technology

  • Human centred design solutions
  • Sensors and actuators

Politics, policy & law
