Construction Timber to Improve Thermal Comfort

The use of construction timber can contribute to smooth indoor temperatures and thereby reduce the heating and cooling demand of buildings.

Envelopes of wood frame houses already have air gaps. There are intentions to use them in systems aiming to reduce the energy loads in winter and to improve the thermal comfort in summer coupling a façade integrated solar air collector with a heavy and ventilated internal wall. The envelope of wood frame houses being light, it is possible to store solar energy in the internal wall. The air in the cells of wood constitutes a natural insulation. For the inhabitants this means heat protection in summer and comfortable temperature in winter.

Construction timber is also recyclable as wood energy as described in the measure Timber Recycling for Wood Energy.
