TN 54: Residential Passive Ventilation Systems: Evaluation and Design - A Critical Evaluation of the Potential for Adapting European Systems for use in North America and Development of a General Design Method

Infiltration has long served the residential ventilation needs in North America. In Northern Europe it has been augmented by purpose-provided natural ventilation systems - so-called passive ventilation systems - to better control moisture problems in dwellings smaller than their North American counterparts and in a generally wetter climate.

TN 53: Occupant Impact on Ventilation

In recent years a substantial number of monitoring exercises have been made to determine the way in which occupants react to and/or are affected by the indoor environment. These cover a diverse range of aspects including:

  • indoor air quality;
  • moisture and condensation;
  • radon ingress;
  • the build up of pollutants;
  • energy use;
  • thermal comfort;
  • draughts;
  • the impact of airtightness and reduced ventilation rates;
  • the actions of occupants in controlling their environment.

 

TN 52: Acoustics and Ventilation

The first chapter aims to provide the reader with an overview of the basics of acoustics, which are required as part of the ventilation systems design process. With this knowledge the designer can, with the remaining chapters, apply these principles to providing quiet and effective ventilation in buildings. A detailed analysis of background, components, problems and methods for achieving quiet ventilation systems in buildings.

TN 51: Applicable Models for Air Infiltration and Ventilation Calculations

In recent years, the 'usability' of ventilation and air infiltration models (both public domain and commercially available) has increased greatly. Possible areas of application for 15 such models are identified in this report. (These are mainly 'network' models.) In addition, it discusses the input data that must be provided in order to use them. The capabilities of the models are described and full contact details on how to obtain them are provided.

 

TN 50: Ventilation Technology in Large Non-Domestic Buildings

Current ventilation practice in large non-domestic buildings as well as future trends and developments are all examined in this publication. Examples considered include atria, auditoria, sports halls, enclosed shopping malls and offices. It is intended for designers, architects, building owners, policy makers and researchers.

 

 

 

 

TN 49: Energy impact of ventilation: estimates for the service and residential sectors.

To quantify the energy impact of air change on total energy use, the AIVC has been conducting a study of current estimates for non-industrial buildings in thirteen major industrialised countries. This document explains how air infiltration and ventilation together account for a significant proportion of energy use in buildings. Air change energy use and its effect on carbon dioxide emissions due to use of fossil fuels are considered. The potential for reduced energy use by improved ventilation control is also reviewed.

TN 48: The Role of Ventilation in Cooling Non-Domestic Buildings

As an introductory note, this aims to place the need for cooling for thermal comfort into the context of overall energy efficient building design. Additionally, it stresses the role of ventilation in meeting cooling requirements. Chapters are included on ventilation and cooling requirements; factors affecting cooling load; ventilation and cooling systems; and energy issues in ventilation and cooling, covering space cooling load, plant load and fan energy.

TN 47: Energy requirements for conditioning of ventilating air.

The objectives of this work are: first to determine the theoretical energy requirements per constant mien unit of outdoor air used for ventilation for a number of different climates and locations in North America and Europe; and secondly to determine the variation of this annual ventilation heating and cooling energy requirements due to the set points for temperature and humidity. The energy impact and/or trade-offs involved between bringing in outdoor air for indoor air pollution reduction and the energy required to condition this sir are investigated in this report.

TN 46: 1994 Survey of Current Research into Air Infiltration and Related Air Quality Problems in Buildings

Provides a platform for the dissemination of information related to infiltration, ventilation, indoor air quality and energy use within buildings by means of a survey and analysis of current research. The current survey reports on research projects from over 250 sources worldwide. The sections include an analysis of the results of the survey, a detailed list of survey replies, which is also available in searchable database format, and contact names and addresses for researchers.

TN 45: Air-to-Air Heat Recovery in Ventilation

Discusses the issues which influence the performance of heat recovery devices within typical building applications. It is intended to cover the three main types if devices installed in ventilation systems in residential and commercial buildings, which are run-around coils, plate heat exchangers and thermal wheels (rotary regenerators). Other systems such as heat pipes are also described briefly.
