VENTILATION SYSTEM Ventilation requirement From the building
regulation 2010 Minimum dwelling ventilation rate = 0,3x floor area
In our case : 0,3x180= 54 l/s= 194,4 m^3/h We use this value to
design our ventilation system Use of a heat and recovery system

ECONOMIC WATER USE Using Restricted taps and low flow taps
results in a saving of 50.6%. Using Rainwater Harvesting results in
a total saving of 65.8% water. This means the water usage is
lowered to less than 80l per person per day, scoring maximum points
according to the code for sustainable homes. Low Water UseLitres
