Energy Labelling of Buildings建筑的能源标签
Today building experts make judgements of the energyperformance of buildings based on drawings and prior knowledge. 今天，建筑专家根据图和先进知识来判断建筑能源的表现
This leads to 'Energy labelling' of the building这导致了建筑能源的标签
However, it is noticed that two independent experts can predict very different consumptions for the same house.
然而，值得关注的是两个独立的专家对相同房屋做出不同的消耗估计

Conclusions – Smart Meters总结—智能测量仪
Reliable Energy Signature.
可靠的能源标签
Proposals for Energy Saving:
节能的提议Replace the windows?
重置窗户Put more insulation on the roof?
加大屋顶隔热材料的使用Is the house too untight?
......
Will be implemented in ‘My House‘ 将被作为“我的家”的补充
Optimized Control 最适当的控制
Optimized use of Solar and Wind Power. 最适当的太阳能和风能的使用
