NET ZERO BUILDINGS

A net zero carbon building is a highly energy-efficient building, with the remaining energy requirements generated from renewable energy, preferably on-site, but it can be off-site if necessary. There should be zero net carbon emissions on a yearly basis. Four of South Africa’s major metros are implementing policies that require all new buildings to be net zero carbon from 2030. Net zero carbon buildings can result in quality housing, local economic development and establishing conditions for grid-interactive buildings of the future.

Summary report on net zero pathway for cities

CSIR comments regarding the net zero carbon pathway for the SA C40 cities. This analysis was performed as part of the work done by the CSIR in support of the City of Tshwane updating of the Green Building Development Policy and By-law and is not a final report but a reflection of work in progress (CSIR, 2020).

Building Consensus for Net Zero Carbon Buildings in South African Cities

This Situation Brief outlines the Status Quo of achieving net zero carbon building targets in South Africa. It considers the importance of net zero carbon buildings, the positions of international and local organisations and the progress made towards net zero carbon buildings in South Africa. Finally, it identifies key gaps that must be dealt with in order to develop consensus on the pathway towards NZC Buildings in South Africa. (Gardner, 2020).

Routes to Compliance note: Notes for Cities

The Net Zero Carbon Building Policy goal is to achieve a reduction in the energy consumption and greenhouse gas emissions of the built environment by reworking the way buildings are planned, designed and erected. This note can be used by Cities either an annex to the Policy or it is incorporated into the introduction (Pegasys, 2020).

Roadmap to Net Zero Carbon Buildings for 2020-2030: Policy Update

This a Roadmap that presents the key activities required by the City to achieve net zero carbon buildings by 2030. The activities highlighted in the roadmap and the corresponding approaches are pragmatic, innovative, and flexible and will be adapted to the global and local context as well as to the evolving national and legal landscape, when and if required (Pegasys, 2020).

New Building Emissions Model

The model calculates electricity consumption and electricity-related emissions from buildings in the residential and commercial sectors for different policy scenarios (business as usual, SANS and local by-laws), based on information entered in the Inputs sheet (SEA, 2019).
