A wooden house should not be hotter than a house made of other construction materials such as concrete or brick, provided that all other factors are equal and the temperature inside the house is more influenced by factors such as thermal insulation, temperature regulation and air circulation than by the construction material.
But there are several reasons why someone might find a wooden house hotter:
Poor thermal insulation:
If a wooden house does not have good thermal insulation, then heat from outside will more easily enter the house during hot weather and this also applies vice versa in winter, where heat in the house can easily escape - Therefore, good insulation it is very important to maintain a comfortable temperature in the house.
Poor air circulation:
Poor air circulation in the house can make the temperature feel hotter - A house that does not have good ventilation can cause heat waves inside and this can also happen to houses with any construction material.
Sun exposure:
If a wooden house is exposed to direct sunlight and does not have adequate window coverings or sunscreen and the temperature inside the house can rise quickly on hot days.
It is important to understand that house construction materials are only one factor in the thermal comfort of a house - Other factors such as insulation, ventilation and exposure to sunlight also play a big role in determining the temperature inside the house.
If you feel your log home is hotter then be prepared to increase the insulation, improve ventilation and use proper window coverings to regulate the temperature inside the home.
