The Regulating Effects of Insulation in your Home

Insulation, Future-Proofing your Home against Varying & Extreme Weather Conditions: When you think about insulating your home and what it does for, you normally think of having a warm, cosy home in the winter and of course this is the main benefit of insulating your home. Insulating you home though can also help on hot days. It can reduce overheating in your home on those hot summer days, and therefore its overall effect is reducing temperature variation in your home, having the temperature in your home at a more constant comfortable temperature for all the seasons of the year. This also has the effect of not only on reducing cost on the heating energy bills in the winter but when those very rare days of cooling that can be needed in Ireland insulation can also help facilitate this. With increased levels of insulation the outside environment becomes less of a factor to the inside temperature.

Responsivity of Insulation: Analysis of temperature data of 10 retrofit houses as part of the SERVE project shows the benefit of insulation. In Graph 1, we can see that even though the temperature variation over a 32 day period (20th May – 20th June) for both outside air temperature and the daily temperature variation (difference between the max and min temperature value of that day). The average daily outside temperature variation is 8.7°C while the average of the entire set of houses is 1.69°C, including some houses that show a higher than normal variation due to low insulation levels. The maximum daily outside temperature variation is 17°C with the max house temperature varying by 7°C (the house with lower levels of insulation). There is one instance there where the daily temperature variation for one house is of 0.3°C when the outside temperature varies by 8.3°C.

Benefits of Insulation: In Graph 2, we can see the reading of a temperature sensor in the houses and the daily max and min outside values. We can see the response of the houses to the outside temperatures. This graph also re-iterate the main benefit of insulation for the climate like Ireland where it benefit heating even in a cold June we can see the minimum daily outside temperature reaching lows of 3°C, on this most of the houses had a temperature range of 17-19°C.

Monthly (May & June) House Temperature Response to External Temperature Disparity

Gain Control of your Household budget: So insulating your home can facilitate warming in the cold winter days, saving you money on your heating bills and provides some cooling on hot summer day. Insulation provide the constant platform to which people can plan their yearly energy bills as the outside temperature became less of a factor on the temperature of your home, extreme winter and hot summer can have less of an impact on your budget. Household budgetary forecasting can now become more of a science that just guesswork and wishful thinking.

Final Thoughts: Insulation is the temperature regulator to defend your home against the outside elements and keeping it comfortable throughout the year.

This analysis is only the beginning; the Tipperary Energy Agency will be collecting this data over two years for 100 houses to produce many other types of analysis. For further information on this or other data sets, contact
