Retrofits for Net Zero – Transforming Existing Buildings into Sustainable Assets
Retrofitting existing commercial buildings is no longer optional as the UK strives to achieve ambitious net-zero targets by 2050; it has become a pressing necessity.
Older buildings are often characterised by energy inefficiency, with outdated heating systems, poor ventilation, and ineffective energy solutions contributing to damaging carbon emissions.
Understanding how retrofitting existing buildings with smart solutions can transform them into sustainable assets, providing long-term savings and benefits to landlords and tenants.
The Importance of Retrofitting for Net Zero
The UK Green Building Council believes retrofitting existing commercial properties is critical to the country achieving its net-zero targets. With approximately 25% of greenhouse gas emissions coming from buildings in the UK, reducing this figure is essential to success.
Benefits of retrofitting existing buildings
Retrofitting existing commercial properties significantly benefits tenants, employees, and landlords, both environmentally and economically. Benefits include:
- Reduced carbon footprint
- Improved energy efficiency
- Lower energy costs
- Higher building value
- Greater appeal to investors
- Improved tenant retention
- Healthier indoor environments
- Contributing to UK sustainability targets
Smart Building Solutions: Technology to Drive Sustainability
Innovative new technologies are already changing how we manage and optimise building sustainability.
For example, data-driven insights monitor building occupancy to improve energy efficiency and control the internal temperature. All of this helps control operational costs, particularly within HVAC systems.
Internet of Things (IoT) systems allow you to manage HVAC systems in real time. Assessing the internal environment allows the system to automatically adjust.
Key components of smart systems include:
- Smart sensors which monitor air quality, temperature, and occupancy to optimise system settings.
- Automated controls adjust lighting, heating, and cooling based on actual conditions.
- Data analytics provide insights into energy consumption patterns, identifying areas for improvement.
- Cloud-based software monitor and manage HVAC systems, providing real-time data and ensuring optimal performance.
Utilising IoT-connected systems allows you to monitor your building performance remotely with a data-driven approach. This allows you to create well-informed strategies to maximise and maintain your building’s sustainability.
Energy Saving Solutions: Essential Upgrades for Sustainability
Smart technologies are one part of the sustainability solution. However, other upgrades can also help improve your building’s efficiency profile:
- Upgrade insulation: Improving thermal insulation helps keep heat in during cold weather and cool buildings during warmer months.
- High-efficiency lighting: Using LED lighting helps reduce energy consumption.
- Optimising your HVAC system: Ensure your HVAC system is regularly maintained. Ensure filters are cleaned and replaced regularly for maximum efficiency.
- Advanced air filtration: Modern air filters reduce the need for outside air intake, ensuring clean indoor air quality.
Upgrading your building for sustainability not only increases energy efficiency. Automated systems monitoring your indoor air quality and making automatic adjustments helps you minimise facility management costs. This allows facility management to focus on more strategic and value-add activities that help boost your profitability.
Cost Savings and Return on Investment (ROI) from Retrofitting
There’s no question the initial investment required to retrofit for net zero can be daunting. However, acting today can lead to substantial long-term cost savings, leading to the return on investment (ROI).
Primary financial and economic benefits include:
- Reduced energy bills with savings of between 20 to 40% depending on retrofitting measures.
- Green-certified buildings can command higher rents and occupancy rates, along with higher property values.
- Government tax breaks, grands, and other financial incentives are available to help with the cost of energy-efficient upgrades.
- Healthy buildings with good indoor air quality leads to more satisfied tenants. This helps you retain good tenants for longer.
- Supporting ESG (Environmental, Social, and Governance) goals can help boost your brand’s reputation.
While much of your ROI will be realised in long-term operational cost savings, you can also look forward to increased profitability in the short term. In addition, sustainable buildings are increasingly more attractive to tenants and investors helping you increase rental income.
Rensair, on the other hand, is a leading provider of low-cost, high-impact solutions perfect for your retrofit, helping you achieve your short-term and long-term indoor air quality, economic and Net Zero goals.
