A comparison of residential ventilation codes and standards requirements in cold climate areas of the United States of America, Canada and selected northern european countries

The study reviewed each Code/Standard with respect to requirements relating to acommon set of ventilation factors and criteria. The main factors include the following:1. Protection against Depressurization - given the increase in more tightly built homes,how do the differing C/S protect against combustion gas spillage into the dwelling.2. Ventilation Capacity - what are the requirements for total mechanical air changerates, and high and low airflow capacities?3. Contaminant Removal - what exhaust requirements are there for specific rooms inthe dwelling?4.

Building envelope, duct leakage and HVAC system performance in HUD-code manufactured homes

Between 200,000 to 300,000 manufactured homes are built to the US Department of Housing and Urban Development’s Manufactured Home Construction and Safety Standards (MHCSS) in the US each year. This paper compares building envelope, duct leakage and HVAC s

Duct leakage in new Washington state residences : findings and conclusions

Many energy codes require that ductwork installed outside of the conditioned space be sealed. Prescriptive codes have no performance standard for what constitutes an acceptable level of duct sealing. Testing and anecdotal evidence indicate that many new homes have extensive leaks on both the supply and return sides of the heating system. A field study of 29 recently built homes was conducted in the Spokane, Washington, area. Systems were visually inspected; all defects were

European collaboration on energy performance regulations (European project ENPER-TEBUC)

The central subject of this Workshop was the challenge offered by energy performance regulations to find adequate solutions for the integration of innovative technologies in such regulations.

Irish regulation for energy efficient housing

Describes the new regulations concerning the energy efficiency of buildings and ventilation requirements that have been adopted for Ireland.

Sol-Vent: development of strategies for the efficient use of solar and passive ventilation in urban buildings.

Describes a project to develop strategies and dissemination material to assist the efficient application of solar and passive ventilation in urban buildings. Describes the website, aimed at the informed architect and engineers specialising in HVAC. Features design solutions in the form of case study buildings and design components. Also presents a review of how current regulations encourage/restrict the application of solar and passive ventilation in urban buildings.

Why and how is airtightness stimulated in the proposed new energy performance regulation for the Flemish Region.

The airtightness performances of buildings and ventilation systems can have a major impact on the indoor climate (IAQ, thermal comfort,...) and on the energy performance. Measurement results for Belgian buildings clearly show that the airtightness is often moderate to very poor. As part of the proposed energy performance legislation for the Flemish Region, it is envisaged to pay attention to the airtightness of buildings and ductwork. In the first part of the paper, results found for Belgian buildings and systems are briefly presented and discussed.

Ventilation in the new French thermal regulation RT 2000.

Ventilation plays an important role in the RT 2000 regulation. This new French thermal regulation takes into account energy for heating and lighting through a C coefficient (primary energy in kWh), as well as summer comfort for non air-conditioned buildings. The paper focuses on the calculation of the C Coefficient. For the ventilation side of it, the calculation method aims both to have simple input data and physically based algorithms. The fact that it was chosen to have a computer based approach made this possible.

Overview of key aspects in the proposed energy performance regulation for the Flemish Region in Belgium.

It is expected that there will be in 2003 an energy performance regulation for the Flemish Region. In the framework of the VLIET-EPIGOON project, a proposal for such legislation is under preparation. This paper describes the global context for the envisaged regulation. Moreover, a number of specific issues are briefly presented.

Energy performance standardisation and regulation: state-of-the-art, challenges and ongoing actions.

Energy Performance standardisation and legislation is receiving an increased interest in many countries. The paper is split up in 3 parts: An overview of the present status: which countries have such regulation in force or under preparation, what is the link with European standardisation? What are the challenges for achieving an effective EP approach? What are important on-going activities?
