## Assessment Instructions

<details>

<summary><strong>Intent</strong>: What is the purpose of this indicator?</summary>

The intent of this indicator is to assess whether the entity includes sustainability elements in its residential lease contracts, with data analyzed to inform future standards development.

In the Residential sector, lease contracts form the foundation of the relationship between landlords and tenants, outlining their respective rights and responsibilities. Promoting sustainability performance through these contracts is essential for aligning both parties with broader sustainability and social goals.

<summary><strong>Input</strong>: How do I complete this indicator?</summary>

Select yes or no. If yes, report (1) the sustainability elements included in the lease contracts and (2) the percentage of contracts incorporating these elements.

#### Terminology

**Data sharing**

> Refers to residents sharing information related to energy or water consumption, production of waste or greenhouse gases, recycling rates, etc. with the landlord.

**Enabling upgrade works**

> The standard lease agreement explicitly includes provisions allowing the landlord to carry out upgrade work on the premises.

**Energy conservation**

> The standards, strategies and actions to manage and conserve energy in a sustainable manner.

**Energy consumption**

> The use of energy by the entity.

**Incentives**

> Incentives can be financial in nature or encompass a variety of approaches designed to encourage utility conservation efforts by residents. Notable examples are the automatic renewal of existing contracts, priority viewing for newly vacant or new assets or the initiative by landlords to set up green energy supply contracts on behalf of residents.

**Indoor environmental quality**

> The overall quality of a building's interior environment, impacting the health, comfort, and well-being of its occupants.

**Sustainable living practices**

> Lifestyle choices and daily actions aimed at reducing an individual's or community's environmental impact while conserving natural resources for future generations. These practices focus on minimizing waste, lowering carbon footprints, and supporting ecological balance.

**Social initiatives**

> Encourage, facilitate or require initiatives that are designed to improve the wellbeing of the premises’/buildings' surrounding communities. Initiatives can relate to provision of healthy food, commitments to human capital, health and safety or above-award pay for building management, responsible use of ground level and surrounding public space that results in enhancement of the surrounding community, etc.

**Sustainable transport**

> Clauses can relate to preparation of an alternative transport report, sharing of information relating to public transport, environmentally low impact transport, end of trip facilities, bicycle racks, car share services, etc.

**Recycling and waste management**

> Issues associated with hazardous and non-hazardous waste generation, reuse, recycling, composting, recovery, incineration, landfill and on-site storage.

**Renewable energy**

> Renewable energy produced on-site, or procured off-site, to meet some or all of the building’s energy requirements.

## Frequently Asked Questions

<details>

<summary>What are "related appendices" to a lease contract in the context of RES6?</summary>

"Related appendices" are documents that are formally provided by the landlord together with the lease contract. These appendices are typically referenced in, attached to, or clearly associated with the lease agreement and may include, for example, resident guidebooks, handbooks, or information packs that accompany the contract.\
\
More general or indirect communication channels, such as building notices, posters, email campaigns, or information hosted on a landlord’s website or online platform, are **not** considered related appendices.
