Utilization Of Heat Recovery Ventilation: Steady-State Two-Zone Heat Loss Analysis And Field Studies, Arnold Janssens, Wolf Bracke, Marc Delghust, Eline Himpe, Silke Verbruggen, Jelle Laverge

International Building Physics Conference 2018

In new houses in Europe the share of mechanical ventilation with heat recovery is increasing as a result of more severe energy performance requirements and of energy labelling for residential ventilation units. The methods used to assess the influence of heat recovery ventilation on the heating energy use in energy labelling and certification are typically based on single zone energy balance equations, although heating behaviour and set-points differ in different rooms of a dwelling. As a result of this the energy savings of heat recovery ventilation as assessed with single zone methods may be larger than when the spatial variations …


Optimal Passive Design Strategies For Nearly Zero-Energy Dwellings In Different Chilean Climates Using Multi-Objective Genetic Algorithms, Daniela Besser, Frank U. Vogdt Sep 2018

Optimal Passive Design Strategies For Nearly Zero-Energy Dwellings In Different Chilean Climates Using Multi-Objective Genetic Algorithms, Daniela Besser, Frank U. Vogdt

International Building Physics Conference 2018

At present, most developed countries attempt to highly diminish the energy consumption of buildings towards nearly zero-energy performances. This study assesses passive design strategies by means of multi-objective optimizations with genetic algorithms, aiming to minimize the heating and cooling demand of typical single-family dwellings in Chile. The results show that the thermal transmittance and airtightness of the whole building envelope should be highly improved from the current limiting values in all assessed locations. Complementarily, strategies for managing overheating would be crucial for avoiding to shift the heating demand into cooling. With this regard, the use of thermal mass, natural ventilation …
