GM: 2021 Resilience

The GM: 2021 Resilience (Re) section evaluates buildings on their climate mitigation and adaptation strategies and encourages the use of nature-based solutions and a greater approach to circularity. It focuses on the protection of place, people and habitat, management of resources and climate risks aligned with the recommendations of the Taskforce for Climate Related Financial Disclosures (TCFD), and the restoration of ecology and implementation of natural climate solutions.

The Resilience section has been created leveraging on the leading urban studies, including the work and recommendations of the Urban Heat Island Mitigation Workgroup, which is mapping the national strategies for reducing urban heat island and improving outdoor thermal comfort.

Projects that are certified under the Living Future Institute Living Building Challenge will receive recognition under the Green Mark 2021 Re section. Refer to Table RE 0.1 Living Future Institutes Certification for the details.

  1. A comprehensive EIA to identify the anticipated effects on the environment a proposed

    development or project may have. The EIA shall identify design measures to mitigate

    negative impacts to the site's environment with a focus on climate change and ecological

    systems. It should describe how the project can contribute positively to the overall ecology

    and biodiversity of the site and its wider context.

  2. Implementation plan that outlines key actions that need to be undertaken to maintain the

    ecological integrity of biodiversity on the site, whether this is existing biodiversity or

    created as a part of the development works.

RE1.2 Urban Heat Island Mitigation

New

RE1.2a Outdoor Thermal Comfort

To conduct environmental modelling of the site to demonstrate that outdoor thermal comfort is

maintained or improved and UHI effect minimized or reduced. Developments should identify and

implement suitable interventions to mitigate the urban heat island (UHI) effect through massing,

material selection, the landscape, (hardscape, softscape) and building surfaces. The model should

be conducted using simulations over the site area, based 12pm (noon) readings for a typical day in

April and October.

Model shall show one of the following:

  • Physiological Equivalent Temperature (PET) of ≤34°C

  • Universal Thermal Climate Index (UTCI) of ≤32°C

  • TSV <+2

RE1.2b Urban Heat Island Mitigation

Adoption of UHI mitigation measures such as:

  • Green and blue spaces for landscaping and roof

  • Roofing materials or coatings or cool paints with high Solar Reflectance Index (SRI) > 40

  • Unshaded hardscape areas with SRI > 39, inclusive of unshaded carparks, internal roads,

    plazas, and pedestrian walkways

  • Use of permeable paving strategies such as gravel or open paving systems.

  • Other performance-based strategies that demonstrate URH effect mitigation.

The site plan shall be used to calculate the site coverage, at plan view, of mitigation measures adopted.

RE1.3 Contextual Response

New

Existing

To demonstrate how the site topography, microclimate, access and connectivity has informed the

design of the urban form and site layout. A site analysis should be conducted to identify the

relationships between human and physical geography of the site and inform how the building

responds to these factors.

Details should include the response to the urban grain, site connectivity and access, provisions

and locations of amenities, and opportunities for green corridors.

A series of simulations and studies of the project should also be undertaken that look at the microclimate

and the response of the urban form generated, including, shading analysis, wind analysis and solar insolation studies.
