This info should be enough. make assumptions if needed.

I$$d like to ask an expert.

Calculate the heat energy consumption of a rectangular building $(15$x $10$x $3$m$)$due to ventilation during a winter day. The outdoor air temperature is provided in the table included with the assignment. Other energy losses can be ignored. Select an appropriate air exchange rate for the calculation. The supply air comes directly from outside and exits at the indoor temperature. Calculate how much heating energy costs for one day using a standard electricity price. Also, calculate how much firewood would need to be burned in a fireplace to compensate for the energy lost through ventilation. Describe how ventilation energy consumption could be reduced. Make the necessary assumptions for the calculations.
