Our Research Areas

We’re investing $5 million into a multi-year, holistic research program. Our list of more than 300 specific technical milestones ranges from new LED encapsulants and drivers to integrated greenhouse control systems implementation. Take a look below to see some of what we’re working on.

CO2 Enrichment

Determining ideal CO2 concentrations

Crop yield is determined by complex interactions between the amount of CO2 a plant absorbs and the daily light integral (the intensity of light and its duration on a given area of the plant). Our team is developing equations that model these interactions, allowing us to pinpoint optimal growing conditions.

Controls Integration

Integrating CO2 and daily light integral (DLI)

We conduct leading edge greenhouse studies and pilot demonstrations of combined light and shade system implementation (LASSI), CO2 enrichment, and energy-efficient LEDs to find combinations that maximize yields and minimize costs.

Dynamic LED Systems

Improving high refractive index (RI) encapsulants

Much of the light emitted from LEDs ends up reflecting back inside the light itself, increasing heat and reducing efficiency. We’re working on coatings that help extract more light from each LED fixture.

Improving thermal management

High-energy LEDs (like those used in greenhouses) typically convert 70% of the electricity they use into heat. We’re working on new ways to remove that heat to increase the efficiency and lifespan of your lights.

Developing high-efficiency LED drivers

As LEDs heat up, they consume more energy. If left unchecked, this process results in thermal runaway, burning out LEDs prematurely. We’re developing new drivers that regulate temperature and energy consumption, saving you money and increasing the life of your investment.

Designing and testing LED fixtures

You need LEDs that provide the spectrum and intensity of natural light without adding heat. GLASE-designed fixtures optimize the light patterns that improve your yields and lower your energy costs.

Developing green LED technology

Deep green LED lights—which are essential for good color mixing—continue to lag behind other colors in energy efficiency. Our team has doubled the green light output for a given power input, with more improvements still to come.

Energy Efficacy

Developing lamp test reports

Our team is developing industry-specific annual reports for commercial horticultural lamps—reports that will help you choose the best available products for your greenhouse.

Studying tall plant canopies

We’re investigating how light is distributed in tall plant canopies such as tomato plants to help you determine the most efficient lighting pattern for optimizing plant response and crop yield.

Reducing energy costs

We’re examining the energy use and costs of various greenhouse lighting systems to help you make informed choices that can save you money.

Developing measurement protocols

Comparison shopping for lighting systems is complicated by the lack of standardized tests for horticultural lighting. We’re developing standard measurement protocols that will help simplify decision-making.

Engineering and Modeling

Integrating CO2 and daily light integral (DLI)

We conduct leading edge greenhouse studies and pilot demonstrations of combined light and shade system implementation (LASSI), CO2 enrichment, and energy-efficient LEDs to find combinations that maximize yields and minimize costs.

Developing energy simulation engine

Traditional energy simulation engines model energy consumption for HVAC, lighting, and water systems for buildings. GLASE researchers are adapting energy simulation engines for greenhouse agriculture, allowing us to better predict greenhouse energy consumption under a variety of conditions.

Constructing baseline energy models

Energy baselines serve as reference tools, showing how much energy a facility is currently using. Establishing baseline models allows the GLASE team to accurately calculate energy efficiency improvements.

Developing integrated control systems

Commercial buildings have long used room control sensors to adjust balances between lights, shade, CO2, temperature, and humidity. We’re adapting and optimizing those controls for greenhouse environments to enable better yields at lower energy costs.

Pilot Demonstrations

Integrating CO2 and daily light integral (DLI)

We conduct leading edge greenhouse studies and pilot demonstrations of combined light and shade system implementation (LASSI), CO2 enrichment, and energy-efficient LEDs to find combinations that maximize yields and minimize costs.

Conducting baseline data collection

We’re not just building the models for determining baseline energy consumption—we’re also collecting that baseline data. Our team pinpoints pilot projects and runs studies to validate our models under real-world conditions.

Spectrum and Plant Sensing

Defining optimal wavelengths

We’re pinpointing the precise combinations of light wavelengths that maximize yields for crops like tomatoes, strawberries, and leafy greens.

Optimizing for leafy greens

Different parts of the light spectrum have different effects on plant growth. At GLASE, we’re learning which narrow regions of the spectrum contribute most to nutrition in leafy greens, allowing us to fine-tune lighting systems.

Automating dimming

LED lighting is capable of fine-grained dimming, allowing growers to take advantage of ample ambient light and lower energy consumption. GLASE’s growth chamber and greenhouse studies pinpoint optimal strategies for automating dimming control systems.
