Reduce HVAC equipment costs
HLR modules clean the air in buildings so that indoor air can be safely recirculated. This allows outside air requirements to be reduced by up to 85% using ASHRAE’s Indoor Air Quality Procedure (IAQP). The reduction of required outside air decreases project first costs by allowing for HVAC system downsizing.
Reduce building operating costs
Lowering outside air requirements using HLR technology and ASHRAE’s Indoor Air Quality Procedure (IAQP) reduces the load on HVAC systems, which in turn saves energy, reduces carbon emissions, and extends equipment life. This is because less outside air needs to be heated in the winter and cooled in the summer before it is circulated throughout a building. Lower outside air requirements also make it easier and less expensive to control humidity. Deploying HLR modules with ASHRAE’s IAQP can deliver up to 40% HVAC energy savings.
Improve occupant health and productivity
HLR technology improves indoor air quality, which has been linked to occupant health and productivity. HLR modules remove contaminants generated by building materials, furniture and other fixtures, and cleaning agents, and by reducing the infiltration of outside air that is often polluted with exhaust from highways and airports, smoke from industrial parks and wildfires, pollen, and ozone, which is a known carcinogen.
Reduce building carbon footprint
Reducing load on HVAC systems by cleaning the air in buildings so that it can be safely recirculated and outside air requirements can be reduced significantly lowers the carbon footprint of buildings by making the HVAC system more energy efficient. Buildings account for approximately 40% of global carbon emissions, and heating and cooling is the single largest energy consumer and contributor to their emissions.
