.
columns = months / rows = hours a day.
.
colors blue = loss of energy. These are concentrated in the winter months and during the hours of the morning and evening. Obviously this is related to the absence or low presence of sunlight.
colors red = power gains. Focus in the summer months, and during the afternoon, with the peak time of 16 hrs. approx. then decay product that decreases solar incidence.
.
There is another reading that we can make this case is that the building envelope study has little ability to store heat from the sun, this property is called thermal inertia . This can be inferred because of gains and losses occur at zero delay. This happens with materials such as tin, once you remove the heat source immediately lose its temperature is equal to the ambient.

2. Annual Chart comfort / thermal discomfort.
Blue bars: discomfort by cooling = heating energy consumption.
Red bars: Overheating = Discomfort in cooling energy consumption.
.
On the basis of a comfort range, eg 18 ° C to 22 ° C, provides the amount of discomfort watts of consumption, ie consumption needed to reach the levels set within the range.
This case reveals a high energy demand in winter and less in summer.
.
interesting thing about these is that the diagnostic results from them, we propose efficient and accurate solutions to improve the thermal performance of building or space in particular: to evaluate various alternative solutions and choose the best combination cost v / s benefit.
