MODEL BASE IMPROVE

The graph above shows the comparison of indoor temperatures in summer (january-february) and winter (june-august).From January to February in summer.In most of the summer, The indoor temperature is basically higher than the outdoor temperature.According to the Mediterranean climate, winter temperatures are generally mild.The difference between indoor and outdoor temperatures is relatively small compared with summer.Generally, the indoor temperature in winter is slightly higher than the outdoor temperature most of the time.

After all of these improvements to the building (applying shading, reduce the window area and replacing building materials). Overall conditions improved significantly in both summer and winter.The building now has thermal comfort of no more than 32 degrees in summer and no less than 15 degrees in winter.

SOLAR PANELThere are 3 user of this residential building ,therefore the total energy consumption of the building is 36.69597kWh/day. It is planned to instail 16 solar panel on the roof of the house to achieve a zero carbon design.The best place to install solar power is north side of the building. There was instail 12 panels on the north side of the roof and 4 panels on northside of the garages. To maximize the output of the each panel, the collector is tilted atan angle of 30 degrees.

Solar modules produce most power when they are pointed directly at the sun.To maximize the output of the each panel, the collector is tilted at an angle of 30 degrees. Summary:The energy consumption reflected in the building has been greatly reduced. The solar power generation system can basically support the daily electricity consumption of the building

WATER AND WASTE MANAGEMENT SYSTEMS

The water management is minimising the water usage. Rainwater recycling systerms can efficiency reduce the amount of water used by households,for example the shower&bath, the laundry water. In order to collect more rainwater. The garaged roof has been enlarged and tilted. The solar panel and shading shelter can collect water as well.The chart above shows the daily water usage per person.The total clear water consumption of three people is 237 Litres per day.

The grey water treatment system also installed in the house. The used water from kitchen, wash machine, bathwill be collect to the filter.The grey water may contain fewer pathogens than domestic wastewater, After filtration, the water can be used to flush toilets and water plants.This application can reduce the requirment for fresh water.improve the water utilization.

The grey water flow in this tank after filet it can be reuse.

The the rain water collect by tank. after filter,it can be use for daily water consumption.

Summary:Nearly 54.5% of the water consumption can be obtained from the rainwater tank. Also,the treat greywater save a lot of clear water.It Improved water utilization rate and environmentally friendly.
