 # monthly_energy_balance_workflow
 
 This tool calculates the monthly energy balance for each building in a given region.
+It provides as results the energy demand and consumption separated in:
+- Heating
+- Cooling
+- Domestic Hot Water
+
+Also, electrical demand of:
+- Lighting
+- Other appliances
+
+And heating and cooling peak loads.
+
+All these results are provided both, monthly a yearly based.
 
 The following assumptions are taken:
 - No building in the region have attics
 - All buildings have basement but those are not heated
-- The construction details come from nrel
-- The usage details come from comnet
-- The heated volume is 85% of the total volume, assuming that the rest is occupied by internal walls
+- The construction details come from nrcan
+- The usage details come from nrcan
+- The system details come from the Montreal Custom catalog
