Appendix: Actions in the low carbon pathway
The low carbon pathway consists of 25 actions, each with its own target:
Action |
Description |
BUILDINGS |
|
New buildings |
|
1 |
Incrementally increase the number of net zero new homes to 100% by 2030. |
2 |
Incrementally increase the number of non-residential buildings that achieve Passive House levels of performance to 100% by 2030. |
Existing buildings |
|
3 |
Retrofit 98% of pre-1980 dwellings by 2050, with retrofits achieving thermal and electrical savings of 50%. |
4 |
Retrofit 98% of dwellings built between 1980-2017 by 2050, with retrofits achieving average thermal and electrical savings of 50%. |
5 |
Retrofit 98% of pre-2017 industrial, commercial, and institutional buildings by 2050, with retrofits achieving average thermal and electrical savings of 50%. |
6 |
Every building will be recommissioned on a ten-year cycle, achieving energy savings of 15% on pre-2017 building stock. |
ENERGY SYSTEM |
|
7 |
Air source heat pumps are added to 50% of residential buildings and 30% of commercial buildings by 2050. Ground source heat pumps are added to 20% of residential and 40% of commercial buildings by 2050. |
8 |
Solar photovoltaic (PV) systems are installed on 80% of all buildings by 2050. These PV systems provide on average 30% of consumption for building electrical load for less than 5 storeys and 10% for multi-unit buildings greater than 5 storeys and commercial buildings. |
9 |
Heat pumps for hot water installations are scaled up to 80% of residential buildings by 2050, and 50% of commercial buildings by 2050. |
10 |
20 megawatts (MW) of commercial scale ground mounted solar PV is installed per year between 2018 and 2050. |
11 |
A 16 MW seasonal storage district energy system is installed in the downtown area. |
12 |
67 MW of energy storage is installed by 2050 to reduce the curtailment of the ground-mounted PV. |
13 |
50 MW of wind energy is installed by 2050 outside of city limits. |
14 |
Local production is maximised, and additional renewable natural gas is imported to displace natural gas consumption in buildings. |
15 |
100 kilowatts of run of river hydro electricity generation is added. |
TRANSPORTATION |
|
16 |
Transit is introduced in areas with high density and insufficient transit. |
17 |
The transit fleet is fully electrified by 2050. |
18 |
The cycling and walking mode share is increased. |
19 |
The percentage of trips that are rideshare is doubled by 2050. |
20 |
A car-free downtown is created by 2040. |
21 |
The municipal fleet is electrified by 2050. |
22 |
100% of new passenger vehicles are electric by 2030. |
23 |
95% commercial vehicles are electric by 2030. |
24 |
100% of new vehicles are autonomous by 2035. |
INDUSTRY |
|
25 |
The efficiency of process motors is increased by 50% by 2050. |
