Scandinavian Homes passive house in Galway with its solar installation will be presented at the International Passive House Conference in Leipzig 2015.
The conference will constitute a forum for the exchange of information regarding global trends in the field of energy efficient building. A wide range of subjects will be covered at the conference to be held on 17 – 18 April in Leipzig: besides the latest research trends, regional and community schemes, cost-effective solutions for residential and non-residential buildings as well as examples of retrofits and of the Passive House Standard implemented in regions with hot climates will be presented. Congress-Center Leipzig, 17-18 April, 2015
Theme 6: 1000 ways to heat a Passive House / Dr Shane Colclough
This paper describes the measured performance of a groundbreaking domestic solar heating system with a Seasonal Thermal Energy Store (STES) which is used to meet the DHW and space heating requirements for a house constructed to the Passivhaus standard. Conclusions are drawn about the extent to which solar energy can assist in achieving NZEB in a Passivhaus in Temperate Maritime Climates, and the key lessons from 5 years of monitoring are reviewed.
Passivhaus coupled with a solar installation of 10.6 m² solar array and associated 300 lit domestic hot water tank, 23m3 aqueous subterranean Seasonal Thermal Energy Store (STES) and HRV system was monitored over a five year period from June 2009 to date. Data was collected at 10 minute intervals, with more than 10,000 data points per day used to analyse system performance
Contents; Key performance data is presented for the installation including
- Heating demand versus PHPP predictions,
- Solar fractions achieved,
- STES tank temperature profile and development of subterranean “buffer zone”,
- Insulation performance compared with predicted performance, and
- Evolution of STES tank loss coefficient.
Conclusions The results of 5 years performance monitoring highlight the key factors required for performance optimisation of such systems. The recorded performance demonstrates the viability of solar thermal installations in helping achieve NZEB when used in combination with a low energy dwelling constructed to the passivhaus standard in a Temperate Maritime Climate – Dr. Shane Colclough, Dr David Redpath, Dr Philip Griffiths, University of Ulster, Newtownabbey, Northern Ireland, BT37 0QB.
The very first timberframe passive house in Ireland is soon celebrating its 10 year. Thousands of interested people from all over the world has visited Scandinavian Homes super passive house during the years. Dr Colclough and University of Ulsters research on large solar-system connected to a seasonal store in a passive house has been recognized globally and the findings has been presented at many international conferences.
The house in Galway is still open for interested public, check out www.scanhome.ie for dates.
