This sub-thesis, under the greater thesis ‘Nordlandsbua: Cabin in Nordlandsruta’, aims to tackle heating and firewood usage in the Nordlandsbua cabin.
Nordlandsbua is a 9,7m2 cabin that will be placed on the site of Tjoarvihytta, about halfway along the Nordlandsruta hiking trail. Firewood transportation to remote sites along the Nordlandsruta begets emissions, especially when firewood supplies run out frequently. In addition, the stove that was chosen as the heating supply in the cabin has a heat output that is far too large for the size of the cabin. Therefore, there is a likelihood that firewood will be overused. These factors, along with the overall aim to design Nordlandsbua as a sustainable cabin, support the need for a calculation of necessary firewood usage to make efficient use of firewood supplies.
This report delves into various calculations and analyses, such as a climate analysis, calculation of the thermal transmittance of the building, establishment of an operative temperature using clo-value and metabolic rate, and a final energy simulation using SIMIEN.
As a result, an estimated firewood demand will be determined in kilograms. This result can be used to establish a rough yearly, monthly or daily firewood need.
