Davey Jackson Elementary - LEED Gold Davey Jackson Elementary School (DJES) is a new 498 student elementary school located in Jackson, Wyoming. DJES was the first school in the State of Wyoming to achieve a Leadership in Energy and Environmental Design (LEED) Gold rating from the U.S. Green Building Council. The team used an integrated design process to meet the functional needs of the facility and minimize the impact on the environment. The team held multiple design charrettes with key stakeholders including school district representatives to address sustainable design strategies including appropriate building orientation, programming, and budgeting. Major goals included reducing energy use by 35 percent and water use by 30 percent, daylighting all classrooms, treating all stormwater before it leaves the site, diverting over 50 percent of construction waste, and achieving good indoor air quality. Energy conservation efficiency strategies included: special attention to the building envelope and glazing specification; The light fixtures and control components were scrutinized to optimize performance; A high performance HVAC system was selected to compliment the other building features that included variable volume air delivery, dedicated outside air ventilation system, and condensing boilers to provide a quality indoor environment. A detailed energy model was developed to assist in the system decision making process and predict energy performance. The energy performance for this facility was calculated to be 54% improvement versus a code compliant facility. Ultimately, the benefit to the owner was a lasting facility specifically designed to minimize the life-cycle cost.

SUSTAINABLE DESIGN PHILOSOPHY Durrant embodies six key principles that we feel are enduring qualities of significant architecture and engineering design. We judge our work by the extent to which that work responds to these guidelines: • • • • • •

Responsiveness Integration with environment Respect for function Expression of meaning Unity of design Cost awareness

The extent to which each principle is found meaningful is dependent on: • • • •

Philosophical intentions of the Client Requirements of the Program Characteristics of the site Building typology

Leadership in Energy & Environmental Design (LEED®) Durrant has been a leader in environmentally conscious design for more than 30 years. We recognize the importance of sustainable design and are dedicated to working with our clients to design buildings that make efficient use of energy, water and building materials. We strive to incorporate energy and water conservation into our projects, to minimize impact on the site and surrounding natural environment, and to use indigenous materials wherever possible. We have also designed both passive and active solar systems, earth sheltered structures, and a wide variety of environmental issues.

Located at the Port of Dubuque, this 17,600-square-foot manufacturing facility underwent a historic renovation that incorporated sustainable aspects throughout. The Durrant design team had a goal of creating a sustainable facility that would stand the test of time and an environment that employees will take pride in and label a great place to work. One unique aspect of this project was our construction waste management process that saved $57,000 in tipping fees at the local landfill as well as over $100,000 in material costs that did not have to be spent due to reused and salvaged materials.
