Consumers, investors and regulators are constantly calling on construction professionals to make more efforts in meeting emission reductions as the effects of climate change arise.
Adding net-zero commercial retrofits is an excellent solution that addresses those calls while benefiting companies moving forward. However, these building additions can be more complex than you’d think.
Mistakes can lead to expensive failures and minimal environmental impact. For the best success, it’s essential to be intentional in planning and mindful of any missteps.
1. Having unclear targets
Reaching net-zero emissions is an admirable yet challenging goal that requires balancing outgoing greenhouse gases with removal. However, while this may be the end goal, brands should prioritise clearer targets for achieving it.
The best way to do so is to define which emissions scopes need to be addressed to meet net-zero goals. Here are the main options to consider:
- Scope 1 discusses the greenhouse gases intentionally emitted into the atmosphere by its own operations. For example, switching from fossil fuels for heating can help address this classification.
- Scope 2 is about recognising the electricity these commercial spaces use and their indirect emissions. It’s critical to support electric grids with less or no climate-polluting power.
- Scope 3 dives deeper into other indirect sources of greenhouse gas emissions from regular operations. These can include options like the materials and supplies you choose to integrate.
2. Planning without a baseline
Another common mistake is to plan without the proper metrics first. The current emissions footprint needs to be understood before actionable targets can be made. That way, numbers can be used to measure against and gauge the project’s progress.
Use the scopes above and note which elements require the most attention. A building can also be certified with energy-efficiency bodies and their standards to identify areas for improvement as a reference.
3. Not accounting for building use
As construction professionals, it’s critical to think about the occupants who will use the building. Rushing into these climate-related goals without considering people’s behaviour could lead to missing crucial solutions that would minimise energy use.
For instance, occupants may leave the lights on and frequently adjust the thermostat. One simple net-zero commercial retrofit fix is to install smart controls that will help them operate more efficiently.
4. Lacking a cohesive roadmap
Many teams fail to combine key actions with their project objectives with a clear roadmap. Questions that need to be answered include:
- What funding or resources are necessary to execute these objectives?
- What is the timeline for meeting both short-term and long-term targets?
- Are there any key steps that need to be taken closer to the retrofit implementation?
5. Missing the mark on materials
Commercial retrofits can go beyond just building additions. They can also encompass key material upgrades that actually help meet goals. For instance, outdated windows and poor insulation materials can sabotage the chances of reaching net-zero emissions.
The roofing should be given special consideration, as it is responsible for regulating temperatures and protecting the overall building.
Asphalt shingles are energy-intensive to manufacture and have a shorter lifespan. Swapping them out for solar roofing or even just more recyclable options like metal roofing can make a world of difference.
6. Refusing technological integration
In established buildings, it would be challenging to incorporate principles such as passive design to reduce energy use. Technological integration is an underutilised approach that can help meet those net-zero goals.
A study found that AI-enabled technologies can address several issues in the creation of sustainable buildings, including retrofit planning. One function is modelling prospective construction plans and their impact on energy use in future climate scenarios.
7. Skipping the offsetting strategy
Offsetting is often treated as a separate concept from net-zero emissions, as the former tends to focus more on achieving 100 per cent carbon removals to meet Paris Agreement goals. However, it can also encompass reducing carbon dioxide emissions to compensate for existing greenhouse gases.
The reality is that focusing on retrofits that improve buildings can be powerful. For example, the swap from fossil fuels to electric heating is a key step that will minimise future emissions.
8. Neglecting financial check-ins
Make sure to understand the financial model and impact behind these construction changes. Retrofitting existing buildings can result in up to 75 per cent less carbon than building from scratch, but it still comes at a cost.
Be mindful of expenses and ensure they yield at least long-term operational savings or other forms of return on investment. Explore additional resources, such as potential government incentives, to help mitigate the funds.
9. Working without collaboration
Architects, engineers and construction teams have to be on the same page at all times throughout a retrofitting project. Unfortunately, miscommunication and a focus on just completing the work independently can result in project delays.
Gather all professionals involved and have an in-depth discussion about the goals and design process. Insights and suggestions can also be sought to further refine the project approach.
Achieve net-zero retrofits mindfully
Mistakes can significantly reduce the overall effectiveness of net-zero commercial retrofits and damage the business image, discouraging stakeholder support. Be deliberate during the planning stage to ensure that installation and use will go smoothly in the future.
