Description
An appendix to the new H1 requirements indicates the importance of orienting a building on site, including some prescriptive measures. Care must also be taken when using a compass to ensure true north is used in calculations – not magnetic north.
The latest versions of H1 Energy efficiency Acceptable Solutions H1/AS1 and H1/AS2 both contain a very similar Appendix D: Orientation. This helps designers and architects ensure the data that they are using in their design and building consent documentation is consistent with the methodologies used to achieve compliance.
