Richardsville Elementary – NET ZERO – Bowling Green, Kentucky

Imagine… a school that is designed and built to produce as much energy on-site as it consumes from the grid  

The ICF schools do not cost any more to build than traditional schools. In USA, the Kentucky Board of Education now requires new schools to be constructed using NUDURA’s Insulated Concrete Forms, unless the designers can provide a reason why they choose not to use it. 

Many schools now in the USA have been build by using efficient materials like Nudura ICF and renewable energy technology, creating an educational space for students that accentuates practical and hands-on experience in learning themes such as geothermal science, rainwater collection, solar panel usage, and wind turbine efficiency 

The Future of Sustainable Building

September 2010 marked the grand opening for Richardsville Elementary, the first net-zero school in the U.S. Warren County School district, the school board responsible for Richardsville Elementary, has been building energy-efficient schools that are being recognized for their innovation across the United States. Richardsville, designed by Sherman Carter Barnhart and located in Bowling Green, Kentucky, was created to be a two-story, eco-friendly and energy-efficient structure that incorporated renewable materials and NUDURA insulated concrete forms for a superior building envelope. The design and north-south site orientation allowed the school to maximize the use of renewable energy resources, such as wind and solar, so that it can produce more energy than it consumes.

It’s a widely discussed topic when it comes to a typical school’s carbon footprint, the effects on human health, and its high energy costs. Research provides evidence that schools throughout North America are moving toward greener and healthier building solutions and the demand for energy performance has become increasingly more important. At 72,285 sq. ft. and generating its own energy, Richardsville is the next generation of educational building standards and a valuable tool to educate students on energy and water conservation as well as the value of recycling. The concerns associated with designing a net-zero structure are usually cost, time, and the best eco-friendly building solution available. In order to meet this list of demands, the Warren County School Board decided to use NUDURA, an industry-leading manufacturer in ICF construction, to maximize the structure’s energy performance and minimize energy costs. The result was a high-performance building envelope using NUDURA forms for the interior and exterior walls.

NUDURA provides a highly insulated concrete wall made up of EPS foam connected by a web that is reinforced with steel and filled with concrete. The walls come in a variety of sizes ranging from 4” to 12” concrete cores and provide performance values as high as R-50.

The benefits of using the NUDURA® Wall System for this structure were its superior strength, maximum energy efficiency, eco-friendly materials, sound and fire resistance, design flexibility, speed of the construction process, and EPS foam that doesn’t support mould growth. The performance value of NUDURA forms used in structures, like Richardsville, can generate energy savings up to 70% annually.

Richardsville Elementary is designed to use only 18 kBtu/sq. ft.— 75 percent less than the ASHRAE 90.1 Design Standard for elementary schools annually. Other “green” components that contributed to the overall net-zero design were: solar panels, geothermal HVAC with CO2 monitoring and de-centralized pumping, solar tubes, Energy Star-rated kitchen appliances, active daylighting, sunshade devices to minimize heat and glare, motion sensors, and an efficient maintenance and operation plan. Reusing materials was another key factor in the design plan. Such as the new gymnasium floor, which was made mostly from bamboo and hardwood sections salvaged from the old gymnasium.

The 500 students attending the Richardsville net-zero school will enjoy a healthy, eco-friendly learning environment that sets the standard high to future generations looking to build sustainable educational institutions. Architects and builders are always looking for solid strategies that reduce energy demands, carbon footprints, and operational costs. The important thing is to have a strategy and a building product that makes the switch to “green” simple. As a key component to the overall building aspect of the Richardsville net-zero project, NUDURA has met and exceeded those highly demanded qualities and continues to help to make “green” schools a possibility for your community.

The Next Generation of Educational Building Standards
Richardsville Elementary is a valuable tool to educate students on energy and water conservation as well as the value of recycling. The halls at Richardsville are decorated and themed with the building’s environmental design features such as it’s water conservation, solar power, recycling programs, and much more. The building also features a wireless outdoor classroom outfitted with its own net-ready solar-powered weather station that is capable of monitoring barometric pressure, rainfall, temperature, humidity, wind speed and wind direction.
