A concrete block wall with external insulation project

A concrete block wall with external insulation project within the low-energy projects category, located in Galway, involves a floor area of 260m². The construction features externally insulated concrete walls and is designed using Passive House PHPP (Passive House Planning Package) software.

Key details of the project:

Construction details:

  • Floor area: 260m²
  • Concrete block wall construction with external insulation.
  • Design based on Passive House PHPP software.
  • Heating System:
  • Nilan Compact P with 3KW (JVP3) geothermal heat pump: The Nilan Compact P system is installed, featuring a 3KW (JVP3) geothermal heat pump. This system is connected to a borehole and is designed to provide both ventilation, hot water production and heating.
  • Underfloor heating: The underfloor heating system is used in specific areas, heating the ground floor living and kitchen areas only. The bathroom/ensuite on the first floor is heated separately.


The project demonstrates a commitment to low-energy construction practices, incorporating external insulation and Passive House design principles. The use of Nilan Compact P with a geothermal heat pump connected to a borehole aligns with the goal of providing energy-efficient ventilation and heating solutions. The selective application of underfloor heating in specific areas further contributes to optimizing energy consumption while ensuring comfort for the occupants.
