At Cairn we take energy performance seriously and ensure our homes are built to maximise thermal efficiency.

This is achieved by using high levels of roof, walls and floor insulation leading air sealing products, excellent air tightness levels and low U-value, high performance windows allied with quality construction methodology as standard.

At our new development at Churchfields, Ashbourne, Co Meath energy saving features combine to deliver dwellings with an A3 energy rating with an estimated cost to the homeowners of less than € 2 per day for heating, hot water, lighting and ventilation.

*€2 is based on results of Sustainable Energy Ireland DEAP software calculation for energy consumption and assumes standard occupancy profile and hot water usage.

In addition to our Homes being highly energy efficient, they also feature cost saving renewable energy technology such as roof-mounted Photo Voltaic cells that provide free electricity from sun-light, high efficiency gas boilers or air-to-water heat pumps that draw heat from ambient external air temperature thus further reducing energy bills.


Future Proofed Homes

Building Regulations require new houses built today must use 60% less energy than a house built in 2005.

Part L of the Building Regulations set out the target U values for a dwelling. U values indicate the rate that heat will pass out of your house and the lower the value the less heat your house will lose. Our mechanical and electrical engineers have calculated that our new homes at Parkside boast an estimated 31% improvement on insulation and heat efficiency to the requirements stipulated in the current Building Regulations

At Cairn one of our goals is to achieve building enhancements that aim to go beyond the current regulations. All our homes are designed to be airtight, fully insulated and to consume the least amount of energy possible. We set ourselves the highest quality benchmark to ensure that you can buy a Cairn home with confidence.


Our Homes and the Environment


Ireland’s Building Regulations for new homes are continually being amended and improved and set a high quality benchmark fully deserving of the homebuyers confidence. The 2011 amendments to the Regulations require a further reduction in primary energy consumption and carbon dioxide emissions. An additional increase in the levels of insulation for walls, roofs and floors is required along with a better U value for doors and windows, increased levels of air tightness and an improvement in the minimum efficiency of gas boilers.

In addition to our homes being highly energy efficient, the renewable energy technology that we install such as roof-mounted Photo Voltaic cells or air-to-water heat pumps further reduce, in addition to high-efficiency condensing gas boilers, also ensures that the carbon footprint of a Cairn home is minimised through these environment-friendly technologies.
