June 2009 Archives



Heat Recovery Ventilation Systems (HRV for short) are becoming very popular in Ireland. They facilitate air flow in a building while preventing unnecessary heat loss through the use of a heat exchanger.

The outgoing warm stale air, heats the incoming cold air.

It is important to clean and replace filters on a regular basis. Boards.ie has an interesting discussion on this topic and the fact that irish government are going to issue guidelines on this.



Schools can get insulated for free

| | Comments (0)


Matthew Collison at fpisolar sent me some interesting info on the Energy Efficiency Scheme 2009 for Schools. 

1)  Scheme covers cavity wall insulation and or attic insulation (in standard pitched roofs....flat roofs / dry lining etc. not covered.) in national schools built before 2006
 
2)  Scheme covers quilt type insulation in attics (fibre glass or rock wool, blown in products excluded) and EPS bead or similar for cavity wall (foam excluded)
 
3)  Scheme covers 100% of the cost
 
4)  School needs to get 3 No. quotations from approved suppliers.  Approved suppliers are the same as those registered for SEI HES Scheme
 
5)  On completion school needs to hire engineer, architect or suitably qualified person to verify that work has been carried out (€200 provided by dept to fund sign off inspection)
 
6)  Dept has set out minimum specification to be achieved

Building an Eco Home - Read the Whole House Book

| | Comments (0)

If you are considering building an energy efficient house, I would recommend that you read the whole house book. This book originally published in 1998 but updated in 2008. It covers all aspects of a sustainable building project. With numerous case studies which highlight the improvements that can be made to a structure it shows the reader how small changes can generate big results.

The CAT centre in Wales publish this book, this centre has been implemented "green technologies" since the 1970s, some of which are only becoming mainstream now.

My colleague Bernie Goldbach wrote an article in April in relation to the greener homes supplement in the Sunday Times. This supplement appeared again this weekend (21st June 2009) the articles prompted me to mention this book. There is a renewed interest in sustainable design, this is something we teach and specialise in Tipperary Institute. We use this book as the student text book for our Advanced Certificate in Domestic Sustainable Energy
