Smart Building: Enhance and Optimize your ventilation with Rensair
Rensair “Smart Demand Controlled Ventilation” (SDCV) provides an excellent Indoor Air Quality environment while significantly reducing energy consumption and carbon emissions by more than 40% in buildings.
Rensair “Smart Demand Controlled Ventilation” (SDCV) takes HVAC efficiency to another level by both part substituting expensive mechanical ventilation with cost-effective air purification and also by optimizing the mechanical ventilation/air purification mix in real time to suit occupancy levels.
Rensair is implementing SDCV with large multinationals, public institutions and leading universities, helping them take large steps forward in reducing energy consumption towards their Net Zero targets and building decarbonization.

Need to rethink how buildings are ventilated– Achieve net zero target
Buildings account for 40% of global energy consumption and carbon emissions. Of that, 40% is directly related to Heating, Ventilation, and Air Conditioning (HVAC), making it the largest line item in a building’s operating budget. In order to meet Net Zero targets, become carbon neutral or reduce net zero emissions, this needs to be addressed.

9 times less energy
Rensair air purification delivers one cubic foot of air for 9 times less energy than what it costs through a traditional HVAC system.
Mechanical ventilation consumes a large amount of energy to condition the air drawn into a room to the right temperature (heated or cooled) and to the correct humidity level. Rensair, on the other hand, simply cleans the air that is already in a room – no conditioning is required.

Smart Demand Controlled Ventilation
SDCV optimizses the ventilation mix in a building by:
- part substituting the mechanical ventilation with a more cost-effective air purification
- ventilating at a rate that matches the building occupancy rate.
The total air volume remains unchanged but energy consumption and carbon emissions are substantially lowered. Further, Indoor Air Quality (IAQ) is typically improved, as outside air in many parts of the world is not clean air.

Real time air quality data
Real-time Indoor Air Quality (IAQ) data is generated by Rensair devices which have built-in sensors. The data is presented on a web based platform or can be transmitted to a client. The IAQ parameters measured are PM1, PM2.5, PM10, CO2, TVOC. Temperature and relative humidity are also gauged.
Rensair uses high quality sensors which are constantly recalibrated to obtain accurate readings. This accuracy is underpinned by having the air sensors incorporated into the air purification unit itself, which is preferable to a wall mounted sensor. See attached simple trial that highlights the importance of the location of an air sensor to ensure accurate IAQ readings.

Advanced IoT
Real time IAQ and Rensair unit operation data from all devices are sent to an intuitive cloud hosted IoT device management platform.
Rensair’s IoT platform allows building and facilities managers to remotely manage all Rensair devices and collect IAQ data in different rooms in a building.
A smart dashboard helps visualise the latest IAQ readings, Rensair unit operation, trend monitors, geolocation and more.
What is Smart Demand Controlled Ventilation (SDCV) ?
Questions
How do air purification and mechanical ventilation work together?
Air purification removes indoor airborne particulate matter and gas pollution through a continuous filtration process. Mechanical ventilation dilutes pollutants by introducing outside air into an indoor space and removing existing air to the outside. Research shows that the two cleaning processes are additive, combining to provide a cumulative improvement in indoor air quality.
What other benefits come from SDCV?
Because a lower volume of air will be ventilated by the mechanical HVAC system, its future maintenance requirement will be lower. Furthermore, any future HVAC upgrade can be completed with a system that delivers a smaller ventilation volume, saving substantial retrofit costs.
What do air purifiers remove?
HEPA filtration has been used in the healthcare sector for many decades. Together with carbon filtration, a well designed air purification unit that uses these technologies will remove airborne viruses, bacteria, fungi, mould spores, smoke particles, pet dander, dust mites, allergens, pollen, ultra fine dust particles, and odours.
