HHSRS Hazard 3 - Excess Heat

Hazard 3 - Excess Heat

This hazard includes threats from excessively high indoor air temperatures.

The major dwelling factors are solar heat gain, ventilation rates, and thermal capacity and insulation of the structure. Smaller, more compact dwellings, and particularly attic flats, are more prone to overheating than are large dwellings.

Vulnerable Group: All persons 65 years or over

Defects & Justifications

• Thermal insulation - inadequate provision for thermal insulation particularly in attic flats.
• Orientation of glazing - large areas of south facing glazing in inappropriately designed dwellings.
• Heating controls - faulty, inappropriately designed, or inadequate controls to the heating system.
• Ventilation provision - inadequate or inappropriate provision for ventilation.
• Ventilation control - inadequate means of controlling the ventilation.
• Disrepair to ventilation - to the system or devices.
