Saving Energy & Improving your Air Quality

Our Internet of Things (IoT) system combines advanced air filtration devices with proprietary energy management software, allowing you to control and monitor your HVAC system in real-time. Using smart sensors, we assess air quality across various commercial spaces to identify inefficiencies and optimise performance.

By implementing our energy efficient solutions and energy saving solutions, you can significantly enhance the performance of outdated or leaky HVAC systems without costly overhauls.

It’s a win-win for real estate owners and occupiers, a practical and flexible approach to solving HVAC challenges. Our solutions not only improve air quality but also support long-term energy management strategies. We move beyond traditional maintenance by delivering cutting-edge energy saving solutions that provide real-time data insights and raise customer service standards, ensuring peak performance and reliability in every building environment.

The problem with HVAC today:

Central HVAC

Mechanical ventilation (central HVAC system) is the largest energy consumption source in a typical office building. Without effective energy management, it leads to excessive operational costs. Our energy efficient solutions help reduce this load and optimise performance.

Physical parameters

Energy use is unnecessarily high due to the large volumes of outdoor air that require temperature and humidity conditioning when entering a building. Traditional HVAC systems make this process costly and hard to control. Our energy saving solutions address these inefficiencies by improving how air is treated and managed.

Traditional ventilation

Traditional ventilation systems aim to dilute indoor pollutants with outside air, but this is energy-intensive and often ineffective. According to the US EPA, indoor air quality is typically 2–5 times worse than outdoor air. Our energy efficient solutions offer a smarter alternative, maintaining air quality while reducing energy demand.

Regulations

New regulations, such as EPC ratings and Local Law 97, alongside Net Zero targets, mean action is essential. However, many existing solutions are costly and slow to deploy. Our scalable energy saving solutions and smart energy management tools help meet regulatory demands faster and more affordably.

Our Energy Saving Solution solves each of these challenges, and we can prove it

We retrofit HVAC systems without the complexities of in-duct work, or the cost of rip and replace. Our engineering team analyses buildings for optimal ventilation, implements standalone filtration devices throughout and adjusts the central HVAC system accordingly, unlocking significant energy efficiencies. All is monitored and managed via our software platform, Rensair Cloud®

SDCV: Smart Demand Controlled Ventilation

Rensair delivers SDCV for organisations to transform their HVAC.

9x less energy consumed per m3 of air through a traditional HVAC system

Rensair Energy Consumption: 0.6 Watts per m3
Typical Ventilation System: 5.5 Watts per m3

Reducing outside air intake, substituting with air purification:

SDCV optimizes the ventilation mix in a building by part substituting the mechanical ventilation with a more cost-effective air purification.
The total air volume remains unchanged, but energy consumption and carbon emissions are substantially lowered.

IAQ – Improving your Indoor Air Quality

Rensair has delivered best-in-class technology and energy saving solutions for decades. Our advanced approach to indoor air quality combines innovation with smart energy management to deliver reliable, long-term performance.. Here’s how our experience shapes our patented, award-winning hardware and energy efficient solution:

1. ENTRY

Polluted air enters the unit from all directions, ensuring complete room coverage and maximising airflow efficiency.

2. PROCESSING

Driven by a powerful centrifugal fan, the polluted air passes through pre-filters and HEPA filters, capturing dust, pollen, and airborne pathogens while maintaining low energy use—supporting our energy saving solutions.

3. CLEANSING

While the HEPA filter traps, the UVC lamp neutralises remaining viruses and bacteria. The process is designed for performance and efficiency, forming part of our overall energy efficient solutions.

4. EXIT

Clean, purified air is released back into the room. Smart airflow design ensures optimal distribution and supports better energy management across your space.

Tried, tested, patented technology, certified globally

Our patented airflow design combines HEPA H13 filtration, UVC light, and gas removal to deliver cleaner air with minimal energy usage. These innovations are part of our broader commitment to energy efficient solutions that reduce environmental impact while improving indoor air quality.

The efficacy of Rensair’s patented technology is validated by leading independent scientific laboratories, including Eurofins, Norconsult, Oslo University Hospital, and the Danish Technological Institute.

Our air purification technology supports energy saving solutions and has been widely adopted by hospitals, dental practices, care homes, and doctor surgeries around the world, including many NHS trusts in the UK.

Rensair meets global air purification standards as recommended by the UK SAGE Committee, US EPA, and ASHRAE and was included in Newsweek’s list of Best Infection Prevention Products 2021. As a key part of building energy management strategies, our solutions offer performance, safety, and efficiency that meet the highest international benchmarks.
