Using PV solar to meet Part L building regulations
The Part L Amendment to the Irish Government’s Building Regulations demands that new build housing projects today must be 60% more energy efficient than the equivalent regulations in 2005.
That’s quite a hike — but renewable energy technologies have come a long way, and have a crucial role to play in delivering the improved energy efficiency specified in the new regulations. One of the most effective and straightforward renewable options to install are photovoltaic (PV) solar panels. We take a look at how PV panels can help you comply with your Part L obligations.
How using the sun’s energy to produce electricity can help you comply with the new requirements
The Part L Amendment to the Irish Building Regulations addresses all aspects of a building’s energy efficiency — from the thermal performance of the construction material used, to the level of insulation applied, to the efficiency of the technologies employed to provide heating, hot water and, increasingly, electricity.
Whether your a building designer, engineer, building contractor or renewable energy installer, meeting Part L requirements has become an integral part of new build housing projects in Ireland today.
Where Renewable Energy Technologies fit in to Part L compliance
The Part L Amendment doesn’t specify a particular renewable energy technology, or advocate any one type of energy solution over another. What it does do is specify that a minimum quantity, expressed in kWh/m2/year, of delivered energy consumption as calculated using the Dwelling Energy Assessment Procedure (DEAP) is provided using a renewable source. There are a variety of renewable sources you could consider for your new build project, including things like heat pumps, biomass boilers and small-scale wind energy, but perhaps the most straightforward and effective source of renewable energy available today (even in Ireland) is the sun.
PV — the solar panel evolved
Solar energy is a tried and tested renewable energy source that has been used successfully in Ireland over recent years. However, with the advent of the latest Part L Amendment (2011) a properly sized thermal solar panel system (the typical set-up for domestic hot water you commonly see installed in dwellings today) will not be enough, on its own, to meet the more stringent renewable energy requirements of the new building regulations.
That’s where photovoltaic (PV) solar panels come in. Rather than collecting heat from the sun’s rays, and using that energy to heat water (as in a standard thermal solar energy set up), PV panels collect the sun’s energy (even on cloudy days) and convert it into a far more versatile and useful form of energy: electricity. Today PV is a tried and tested renewable energy technology, and modern PV panels are extremely efficient, effective and, just as importantly, are straightforward to install and maintain.
Installing PV Solar Panels is the most cost effective way to ensure your new build meets the Part L building regulation requirements for renewable energy contribution.
