Changing the risk profile of construction should unlock investment into the industry.
This is in contrast to a UK Part L1a compliant building, which in order to become net zero would require a PV array larger than the area available on its roof.The difficulty in installing adequate PV on multi residential developments will be even greater.
The only immediate pathway for these dwellings to become net zero is to invest in either a zero carbon PPA or carbon offset scheme, both of which come with significant increases in the cost of purchased electricity..Embodied carbon in sustainable building design.On one hand, a Passivhaus building will need triple glazing, additional insulation and airtight membranes.
The heat pump may contain refrigerants with high global warming potential and the MVHR unit will require insulated ductwork.Much of this may be made out of materials with high embodied carbon such as aluminium or blown plastics.
This additional material volume becomes additional embodied carbon.. On the other hand, a Passivhaus design tends to be a more compact shape, thus less materials used.
Due to its more efficient envelope performance, a Passivhaus building needs a small heating system, and due to its reduced energy demand, it requires a smaller PV array.A chip can, therefore, be a whole factory, a building, a production line, or a single machine within a production line.
These different levels will often result in a hierarchy of Chips, so that big Chips can later be broken into small Chips.They're used in different ways at different stages of a project, or in different ways by different users within a project..
The data structures that we build around Chips allow data to be aggregated between different levels.. We can associate any type of data with a Chip.Conventional engineering data is perhaps the most obvious, but we also include data like staffing levels, containment requirements, power consumption, or even the level of design uncertainty.
