Immediate Payback with CAPEX Savings:
Outside air can represent up to 50% of the HVAC load. With a 60-80% reduction in outside air, HLR Technology significantly reduces the load on HVAC systems, allowing you to downsize or outright eliminate elements of that system. Being able to buy a smaller, less expensive dedicated outdoor air system (DOAS) when you start construction or eliminating demand control ventilation (DCV) during a retrofit are just a couple examples of potential upfront savings. Others include:
- Eliminate or downsize energy recovery ventilation (ERV)
- Downsize the rooftop unit (RTU) or air handler unit (AHU)
- Downsize chiller or cooling tower
- Reduce piping size
- Reduce outside air and exhaust duct sizes
- Downsize boiler or electric heater
- Energy and OPEX Savings
In addition to the 20-30% energy savings mentioned above, HVAC maintenance costs go down and parts don’t need to be changed as often because the HVAC equipment is no longer overworked. For instance, the reduction in outside air means that air filters need to be changed less frequently.
HLR Technology improves indoor air quality in two ways. It cleans indoor air, removing contaminants at the molecular level. It also reduces the need for bringing outdoor air into the building. While outdoor air may be called “fresh air,” it’s hardly fresh. Outdoor air is full of pollutants and reducing ventilation keeps those pollutants out of the building. Indoor air quality is important for more than health and comfort. Studies show that improved indoor air quality increases employee productivity. The National Bureau of Economic Research wrote:
“We find that higher levels of air pollution, commonly found in major cities, decrease worker productivity.”
A Harvard study showed that improved air quality led to a $6,500 per employee productivity increase. Based on financial numbers from the Harvard study, a 1% improvement in productivity in a typical office will pay for HLR modules in just 3 weeks.
Most major cities offer utility rebates for energy efficient buildings. These financial incentives are designed to encourage organizations to design buildings to green energy standards or to minimize energy waste. Different cities and states have different programs with various benefits for green construction from direct rebates to grants, financing, tax deductions, tax credits, incentives, and more. Utility rebates for using HLR Technology can go as high as $12,000 per module. The utility rebates added to the capital expenditure savings from HLR Technology enables immediate payback on HLR modules.
Change is in the air. The days of air replacement for managing indoor air quality are over.
