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.

TN 44: Numerical Data for Air Infiltration and Natural Ventilation Calculations (replaced by Guide GU05)

Organisations in many countries have contributed data to the AIVC to establish a unique collection of numerical data suitable for design purposes and model evaluation. By combining information from these multiple sources, it is possible to consider a far wider range of operating conditions than would be possible by using the results from a single set of measurements alone. The analysis presented in the report is in three sections covering component leakage data, whole building leakage data and wind pressure evaluation.

TN 43: Ventilation and building airtightness: an international comparison of standards, codes of practice and regulations. (replaced by TN55)

The purpose of this comparison of specified airtightness and ventilation rates is to provide a reference document for all those involved in ventilation and building research. It summarises available airtightness and minimum ventilation rate requirements in the AIVC's Member Countries. It also examines a number of indoor air quality standards. Certain analyses have also been included, whenever uniformity of standards permits.

TN 42: Current Ventilation and Air Conditioning Systems and Strategies

The aim of this study is to examine common ventilation and air conditioning systems and strategies for both domestic and commercial buildings in the member countries of the AIVC. To help identify common systems, a literature search was conducted and the system descriptions of two professional institutions and one commercial supplier were examined. This led to the establishment of a common classification of ventilation and air conditioning systems.

TN 41: Infiltration data from the Alberta Home Heating Research Facility.

The infiltration data set covers December 1990 to October 1991 from Reference Unit #5 at the Alberta Home Heating Research Facility (AHHRF) with a total of 6063 hours of data. The facility is made up of six permanent test houses, five of which are built to residential wood frame construction standards with a sixth house of masonry construction. The six unoccupied test houses have been continuously monitored since 1980 for building envelope energy losses and ventilation rates.
