The Fort Huachuca Accommodation School District:1,300 Students

Grades K-8

Students are primarily from military families

Located 45 minutes southeast of Tucson, Arizona

Located on the U.S. Army’s leading intelligence training installation

Educational Leadership from the Superintendent

Conceptual Vision

A state of the art middle school to house grades 6, 7 and 8 whose instructional program is driven by technology. To us a

“Technology Driven School” has two components. One is centered around the INSTRUCTIONAL opportunities of

technology. And the second is driven by CONSTRUCTION and OPERATIONAL opportunities of technology.

21st Century Learning Concepts

Learning opportunities enhanced through technology

Collaborative instructional space supports active student

engagement

Communities of global inquiry

Instruction is interdisciplinary and

projects-based

Students at the center of the learning processRelevance prevails

Learning experiences are embedded in authenticity

Interactions model meta-cognition

Inquiry based activities using synthesis and analysis

Summary of Instructional Technology• Integrated Delivery of instructional material.

• Inter-Disciplinary study opportunities and instruction.

• Hands-on technology for every student (laptop or iPad).

• This is a ‘Hot Building’. Wirelessly connect throughout. Indoors and out.

• There is a ‘Hottest Spot’ or Nerve Center. This ‘Space’ looms over the classroom spaces. This traditionally would be the media center.

• We recognize that we do not need a library as we know it today.

• We recognize that few textbooks will be needed in our school, especially in the upper grades.

• We believe that technology usage will be different in Grades 6, Grades 7 and Grades 8, as this relates instructional delivery.

• Experimentation is a key to our instructional process.

• Individual and small group work takes place daily, informally and spontaneously.

• Critical skills of thinking, working together and research are paramount. ‘Real world’ collaborative work focus is integral for daily instruction.

• Every space in the building and on the school site must be considered a ‘learning space’. Hallways, walkways, patios, play areas are all opportunities for learning and communication.

• We believe that our school will offer a great sense of security to our students. Our students need their ‘place’, their friends, their opportunity for learning in a safe, secure and perhaps residential scale environment.

• From a comparative standpoint, it is fair to think of the instructional delivery program as a Montessori Program for Middle Schoolers. Individual learning styles, individual progress, interdisciplinary study and exploration and spontaneous learning opportunities all driving the instructional program, with tomorrows technology.

Summary of Building TechnologyThe integration of solar, wind, geothermal and water harvesting and reuse are basic components to the design and operation of this building.

Material selection will be focused on green products and unique furnishings that support technology usage, have a residential feel and scale. Furnishing should be comfortable for students and flexibility in usage.

Construction methodology must be sensitive to the environment on a daily basis. Concern for emissions, handling waste and preserving land and plants must be evident.

The anticipated building systems lead the District to the need for a building management services contract at the time we open the new school to assure safety and cost efficient operation of the new building.

All building systems should lead to learning opportunities. View of building operational systems, color coding, measurement and any other real world opportunity for learning needs to be captured.

Educational ProgramOur Vision:

Real world, authentic Project Based Learning

STEM Driven, integrated, group instruction

Supported by integrated technology

Student Centered, Teacher Facilitated

All based on Dr. Frueauff’s research and experience

Electric, Solar, Water and Wind are all monitored for student study purposes

Page 9: USGBC Annual Conference Arizona Chapter March 20, 2013 The New Colonel Smith Middle School Complex Arizona’s First Net Zero School.

Design Criteria:

A ‘future proof’ school……….. flexibility

Support Project Based Learning model

Learning must start immediately when student steps on to the site

Every square foot indoor and outdoor must provide a learning opportunity

Support the community environmentally

A sense of ‘Place’ for students

Page 10: USGBC Annual Conference Arizona Chapter March 20, 2013 The New Colonel Smith Middle School Complex Arizona’s First Net Zero School.

What Net Zero Means to Us

Sustainable Performance of our building.

Real cost savings for the school district.

A learning opportunity for our students.

Doing the right thing for our community.

Key Sustainable ElementProviding an awareness of sustainable practices and respect

for our environmental resources to STUDENTS.

Students are our most sustainable resource.

Page 13: USGBC Annual Conference Arizona Chapter March 20, 2013 The New Colonel Smith Middle School Complex Arizona’s First Net Zero School.

ObjectivesNZEB primary principles:• Carefully designed daylighting, turn electric lights off, solar gain

less than electric lighting internal heat gain• Optimized HVAC designed to daylighted building• Control over all other loads, especially computers• Minimum quiescent base load

Page 14: USGBC Annual Conference Arizona Chapter March 20, 2013 The New Colonel Smith Middle School Complex Arizona’s First Net Zero School.

Procedures• Fully daylight all high-

occupancy-hour spaces• Don’t waste cooling energy on

low-occupancy-hour spaces• Primary source: north sky

clerestories• More lumens per watt than

other daylight orientations• Secondary sources• Shaded south daylight• Diffusing skylights• Windows

NotesDesigned to operate without electric lighting by day in highly occupied spaces

Very efficient dimmable electric lighting is provided with daylighting controls

Spaces not fully daylighted have low hours of general use or useful low light levels

Building Energy Model ProcessHourly Analysis Program (HAP) Version 4.51

Estimating loads and designing systems

Simulating energy use and calculating energy costs

Three-step process

Define building

Create mechanical systems

Run annual simulation

Page 22: USGBC Annual Conference Arizona Chapter March 20, 2013 The New Colonel Smith Middle School Complex Arizona’s First Net Zero School.

1. Define Building

Building Envelope constructionsIdentify internal loads: Lighting, equipment & peopleDetermine how building is utilized: When lights are on & when people occupy the buildingType of walls, roof and insulationWindow U-ValuesSolar heat gain coefficients

2. Create Mechanical Systems

Group into thermal zones (under control of one thermostat)Calculate outdoor air ventilationAssign appropriate/

desired HVAC equipment: split system DX units or large central air handling units

3. Run Annual Simulation

Identify all items that consume energyEnter accurate fan power and mechanical equipment efficienciesAssign utility rates to electric, natural gas, etc.

THEN HAP estimates annual energy usage & energy costs by simulating building operations based on 8,760 hours in a year

Compare results & costs to determine best design
