Decarbonising Assets Using Technology and Retrofits: A Comprehensive Approach

In recent years, the need to decarbonise our built environment has gained increasing importance. Climate change, driven largely by the emission of greenhouse gases, presents significant risks to both our natural world and human systems. Governments, businesses, and individuals are therefore focusing on reducing carbon emissions to limit global warming. One vital area of focus is asset decarbonisation. This includes buildings, infrastructure, and other physical assets. Technology and retrofitting can play a crucial role in achieving decarbonisation goals. We explore how technology and retrofits can be utilised to decarbonise assets, with a specific focus on the UK. 

The Need for Decarbonisation is undeniable

The UK government has committed to reaching net zero carbon emissions by 2050. Achieving this target requires a multi-sectoral approach, with buildings representing a significant portion of carbon emissions. According to the UK Green Building Council, buildings are responsible for 25-30% of the country’s total carbon footprint. The decarbonisation of existing assets is essential if the UK is to meet its climate goals. Moreover, given that a large proportion of current buildings will still be in use by 2050, retrofitting becomes a critical strategy. This process involves updating existing assets with energy-efficient technology and design to reduce their carbon emissions.

Technology and Decarbonisation

Technological advancements are at the forefront of decarbonisation efforts. In terms of energy efficiency, renewable energy generation, and building management, technology can significantly reduce carbon emissions across various sectors.

1. Smart Building Management Systems (BMS)

Smart Building Management Systems (BMS) allow for real-time monitoring and management of a building’s energy usage. These systems are powered by advanced sensors and automation technologies, which can adjust lighting, heating, ventilation, and cooling based on occupancy levels and external weather conditions. BMS can optimise energy consumption, reduce waste, and lower carbon emissions. For instance, lighting can be dimmed or switched off automatically when a room is not in use. Similarly, heating systems can be adjusted according to weather patterns, ensuring that energy is not wasted in overcompensating for temperature changes. Importantly, some of these systems such as AssetBook IoT are genuine unification platforms so all assets can be working together, in harmony and sharing real insights.

2. IoT and Energy Monitoring

The Internet of Things (IoT) enables detailed monitoring of energy use across entire building portfolios. IoT-connected devices can provide asset owners with comprehensive data on where energy is being consumed, identifying inefficiencies and opportunities for improvement. Smart meters and energy monitors can be installed across all areas of a building to track usage in real-time. Once data is collected, advanced analytics can be used to inform decisions on where energy-saving measures can be implemented, further aiding decarbonisation efforts. IoT is the key to really understanding operational efficiency and then how to eliminate waste.

3. Renewable Energy Integration

A key aspect of decarbonisation is the transition from fossil fuel-based energy sources to renewable energy. Solar panels, wind turbines, and heat pumps are examples of renewable technologies that can be integrated into existing assets. In the UK, the uptake of rooftop solar panels has increased in recent years, with both residential and commercial buildings benefitting from on-site energy generation. Heat pumps, which extract heat from the air or ground to warm buildings, offer an energy-efficient alternative to traditional gas boilers. These systems, when combined with energy storage solutions, such as battery storage, can make buildings largely self-sufficient in their energy requirements, significantly reducing reliance on carbon-intensive grid electricity.

4. Energy-efficient Appliances and Lighting

The adoption of energy-efficient appliances and lighting solutions can play an essential role in reducing emissions. LED lighting, for instance, uses a fraction of the energy consumed by traditional incandescent bulbs, while modern appliances such as refrigerators, washing machines, and heating systems are designed to use minimal energy. Investing in such technologies as part of a retrofitting strategy can lead to significant long-term savings in both energy consumption and carbon emissions.

5. Advanced Insulation Materials

Improving insulation is another crucial way to decarbonise assets. Advanced insulation materials, such as vacuum insulation panels and aerogels, offer superior thermal performance compared to conventional insulation methods. Retrofitting buildings with these materials reduces the need for heating and cooling, subsequently lowering energy consumption and carbon emissions. The use of technologies such as infrared imaging to identify areas of heat loss can inform targeted insulation upgrades.

The Role of Retrofitting in Decarbonisation

Retrofitting involves upgrading existing buildings and assets to meet modern energy efficiency standards. It is a particularly important strategy for decarbonisation in the UK, where much of the building stock is old and was not designed with energy efficiency in mind. Retrofitting can take many forms, from minor adjustments to full-scale refurbishments, and offers considerable potential for reducing carbon emissions.

1. Thermal Efficiency Improvements

A primary focus of retrofitting is improving a building’s thermal efficiency. As noted earlier, this can be achieved through better insulation, but it also extends to replacing single-glazed windows with double or triple glazing, draught-proofing, and installing energy-efficient doors. The goal is to prevent heat loss during colder months and reduce the need for artificial cooling in the summer. Enhanced thermal efficiency not only cuts energy use but also leads to improved occupant comfort.

2. Heating System Upgrades

In many older UK buildings, gas boilers are the main source of heating. However, these systems are carbon-intensive and inefficient compared to newer technologies. Retrofitting projects can involve replacing gas boilers with low-carbon alternatives such as electric heat pumps or hydrogen-ready boilers. These systems are significantly more efficient and can drastically reduce carbon emissions. Additionally, the integration of smart thermostats allows for more precise control of heating, ensuring that energy is not wasted in unused areas.

3. Building Envelope Enhancements

The building envelope, which includes the walls, roof, windows, and doors, plays a crucial role in energy efficiency. Upgrading these elements as part of a retrofitting process can have a major impact on a building’s energy consumption. For instance, adding external insulation to walls, improving roof insulation, and upgrading windows can all enhance the building’s energy performance.

4. Ventilation and Air Quality

Effective ventilation systems are essential for maintaining good indoor air quality, but traditional ventilation methods can also lead to significant energy losses. Retrofitting projects often involve the installation of mechanical ventilation with heat recovery (MVHR) systems. These systems extract stale air from inside the building and replace it with fresh air from outside while recovering heat from the outgoing air. This reduces the need for additional heating, contributing to overall energy savings.

Challenges and Considerations

While the benefits of decarbonising assets using technology and retrofits are clear, there are also challenges to consider. Cost is an obvious barrier, particularly for large-scale retrofitting projects. Initial investments can be high, and while long-term savings are expected, the upfront costs may deter some asset owners. Government incentives and subsidies, such as the Green Homes Grant in the UK, can help alleviate these costs, but broader policy support will be essential in driving widespread adoption. Using more modern and agile solutions such as IoT can deliver very quick ROI or return on investment because they use easier to deploy wireless infrastructure and focus on delivering meaningful gains from day one.

Another challenge is the disruption caused by retrofitting, particularly in occupied buildings. Retrofitting can be a time-consuming process, and the need to minimise disruption for tenants or occupants adds complexity to the project. Again, modern wireless solutions, careful planning and phased implementation can help mitigate this issue while keeping costs down.

What are you waiting for?

Decarbonising assets is a vital component of the UK’s path to achieving net-zero emissions by 2050. By embracing modern technology and retrofitting existing buildings, significant reductions in carbon emissions can be achieved. The use of smart building management systems, renewable energy integration, energy-efficient appliances, and advanced insulation materials offer immediate opportunities for decarbonisation. Retrofitting, particularly in terms of thermal efficiency and heating system upgrades, is crucial given the age of much of the UK’s building stock. While challenges such as cost and disruption exist, government support and a long-term view on energy savings can help overcome these hurdles. As the pressure to reduce carbon emissions intensifies, decarbonising assets through technology and retrofits will be essential in shaping a more sustainable and resilient future. Our business is deploying solutions that deliver, our shortest ROI was just 6 weeks (in a very wasteful environment) but often financial paybacks can be much quicker than imagined and there are many tangible benefits as a value add.
