How are Part O Calcs surveys conducted?

Part O Calcs cover the following key aspects: 

  • Insulation: Part O often includes requirements for thermal insulation in buildings such as walls, roofs, floors, and windows. It aims to limit heat loss and enhance energy efficiency.
  • Air Tightness: Buildings should be constructed to minimize air leakage. Air permeability tests may be required to demonstrate compliance.
  • Heating and Cooling Systems: Regulations may specify efficiency standards for heating and cooling systems, including boilers, heat pumps, and air conditioning units. 
  • Ventilation: Part O may include requirements for the provision of ventilation in buildings while considering energy efficiency.
  • Renewable Energy Sources: The regulations may encourage or mandate  renewable energy technologies to reduce reliance on non-renewable energy sources.
  • Lighting: Part O may include provisions related to energy-efficient lighting systems, promoting the use of technologies such as LED lighting and lighting controls.
  • Building Services: Regulations may address the energy performance of various building services, including hot water systems, pumps, and other components.
  • Conservation Measures: Part O may require the implementation of measures that contribute to overall energy conservation, such as the use of energy-efficient appliances and controls.
