Retain, repair or replace
Review structural, architectural and service elements so useful components are retained where practical and unsuitable elements are addressed.

Sustainable Renovation and Building Refurbishment in NSW
A more sustainable renovation starts with the existing building: its condition, useful components, performance gaps and the practical scope needed to achieve a durable result.
Start With the Existing Building
Retaining and upgrading a sound existing building can avoid some demolition and replacement work, but retention is not automatically the best outcome in every case. Water ingress, structural movement, ageing services, hazardous materials, access constraints and earlier alterations can change what is practical.
Define the required outcome, gather available plans and approvals, and identify where investigation is needed before selecting products or committing to a construction budget. Designers, engineers, certifiers and other specialists should be appointed where their advice or regulated responsibilities are required.
Practical Refurbishment Opportunities
The right priorities depend on the building, the proposed use and the findings of the project team.
Moisture and durability
Investigate leaks, drainage, waterproofing, corrosion and material compatibility before finishes conceal the causes of deterioration.
Envelope and services
Consider insulation, glazing, shading, ventilation, lighting, controls and plant performance as coordinated building systems.
Materials and waste
Plan accurate quantities, careful removal, reuse where suitable and responsible disposal while checking performance and compliance requirements.
Water use and management
Review fixtures, hot-water systems, drainage and suitable water-reuse opportunities against the property, approvals and maintenance needs.
Staging and handover
Coordinate occupied areas, temporary protection, access, commissioning, warranties and the records needed to operate completed upgrades.
How Remedial Work Can Support Long-Term Performance
Sustainability objectives do not remove the need to address defects. A refurbishment may first require investigation and repair of water ingress, concrete deterioration, cracking, corrosion, movement or failed building-envelope elements.
SCE’s Building Remedial Services explain the construction pathway, while the Waterproofing Remediation service covers moisture-related work. The exact repair design and compliance pathway remain project-specific.

A Practical Planning Sequence
- Define the outcome. Record the functions, defects, comfort issues and project priorities to be addressed.
- Review existing conditions. Gather records and identify where intrusive investigation or specialist assessment is needed.
- Confirm approvals and responsibilities. Establish the likely planning, strata, heritage, design and certification pathway.
- Compare coordinated options. Consider construction scope, service life, maintenance, energy and water performance, access and reasonable contingency.
- Plan delivery and handover. Agree staging, quality checks, commissioning, completion records and ongoing care requirements.
Frequently Asked Questions
What does sustainable renovation mean?
It means planning upgrades to an existing building with attention to condition, durability, resource use, energy and water performance, construction waste, maintenance and service life. The appropriate priorities depend on the property and project scope.
Is retaining an existing building always more sustainable?
No. Retention can avoid some demolition and replacement work, but serious deterioration, unsuitable materials, performance limitations or disproportionate repair requirements may change the assessment. Compare options using current building evidence and appropriate specialist input.
Which upgrades should be assessed first?
Start with defects, water ingress, structural concerns, safety, the building envelope and ageing services. Once essential risks are understood, the project team can assess insulation, glazing, ventilation, lighting, controls, fixtures and other performance improvements.
How does remedial construction fit into a sustainable refurbishment?
Remedial work can address deterioration that would otherwise limit the useful life or performance of the building. Repairs should be based on the diagnosed cause, compatible materials, an appropriate design where required and a practical maintenance plan.
Do energy or water upgrades require approval?
Requirements depend on the property, the work and the relevant authority or strata controls. Structural changes, external alterations, services, heritage considerations and regulated building work may require additional design, approval or certification.
How should lifecycle cost be considered?
Compare more than the initial construction price. Consider expected service life, maintenance, access, replacement intervals, operating requirements, warranties and the risks of leaving known defects unresolved. Savings or value uplift should not be assumed without project-specific evidence.
When should I contact SCE Corp about a refurbishment?
Contact SCE when you have an identified property and project objective and want to discuss construction scope, buildability, staging, remedial coordination or the next practical step. Bring available plans, reports, approvals and known-condition information.
