Agenda · What is a Green Building? · Traditional Design · Integrated Design ¨ Overcoming Obstacles ¨ Integrated Design Team · Features of High Performance Design · High Performance Results · Q&A
What is a green building? · · · Senator Broadway · Downsizing mechanical equipment (improving performance of building envelope) · · Lower energy cost J. J. Pickle Reduce construction waste (optimizing building dimensions) Lower water cost (indoor & outdoor) Reduce cleaning & maintenance Improved health
Does a facility impact student achievement? · Warm/stuffy room · Air quality (carbon monoxide) · Ventilation · Lighting · Acoustics – heat and air systems, etc.
Research Studies www. edfac ilities. org
Architects/Partners · Jackson, Brown, King Architects, Inc. · Trane – Bill Harrison, Teri Borton, Chris Ladner · Third party validation on energy cost – Weidt Group, Minnesota · Other groups
School Board · Presentation to School Board on green buildings & LEED* certification · Create a design team · Design a high performance building · Pursue LEED certification · Push to the point of diminishing returns *LEED = Leadership in Energy & Environmental Design
Board Commitment · Understood potential for increased upfront cost · Valued designing building to improve academic programs · Benefits to students, staff, & community · Wise use of tax money as an investment
High Performance Design Team · Owner ¨ School District Administration ¨ Maintenance Staff · · · Architect Energy Services Performance Contractor Equipment Suppliers · Energy Engineering Firm · LEED Accredited Professional · · Mechanical Engineer Electrical Engineer Commissioning Agent Cost Consultant
Bryant Schools Traditional Design · 3 previous schools with same basic layout over 10 years · Traditional design, bid, build process ¨ interaction was almost exclusively with architect · 4 classroom pods with central admin, library and cafeteria · Focus was to minimize first cost as well as academic programs · Budgeted based on previous building plus inflation

Design Team Went to Work Considering · Academic programs · Day lighting · Energy efficient equipment · Reduced maintenance (inside & out) · Improved academic performance ventilation & acoustics · Recycled material · Cost analysis
Obstacles to High Performance Design · · · Budget based on code compliant building Board and district agreed to apply for USGBC’s LEED-NC certification for the new facility Learning curve for all parties ¨ Administration ¨ School board ¨ Design team ¨ Community Something new and different Can we afford it? Is this really worth the effort?
Overcoming Obstacles · Financial ¨ Performance Contracting v Traditionally used to fund energy saving measures in existing buildings v Act 58 of Second Extraordinary Session of 2004 extended performance contracting to new buildings v Choices related to building materials, building orientation, and other fundamentals affecting building efficiency could be made during design and funded over 15 years
Overcoming Obstacles · Financial ¨ Performance Contracting v Guaranteed energy and operational savings could leverage dollars needed to complete the high performance/LEED project v Allowed more life cycle efficiency into the building plan
Overcoming Obstacles · Integrated Design ¨ Early involvement with Department of Education – Facilities Division ¨ Early involvement of all members of design team ¨ Collaborative design approach v Interactive communication with all team members v Regularly scheduled team meetings
Overcoming Obstacles · Integrated Design ¨ Informational sessions/updates to school board v Sustainable building practices v Value to students, staff, and community ¨ Detailed specifications outlining sustainability/LEED requirements
High Performance Design Features · Architectural Features ¨ Site orientation with north and south facing windows ¨ Overhangs on southern exposure ¨ Stained concrete floors ¨ Formaldehyde free materials ¨ Re-cycled materials ¨ Low VOC finishes ¨ Reduced lay-in ceilings
High Performance Design Features · Architectural Features ¨ Sustainable landscaping ¨ Reduced impervious pavement ¨ High performance window glazing ¨ High thermal mass structure ¨ Reflective, white R-30 roof ¨ R-20 wall insulation
High Performance Design Features · Mechanical Systems ¨ Right-sized heating, ventilation, and air-conditioning (HVAC) systems based on computer modeling and life cycle analysis ¨ High efficiency, zoned split systems ¨ Dedicated Outside Air System ¨ Occupancy sensors ¨ Building automation system ¨ High efficiency domestic hot water ¨ Low flow toilets and urinals ¨ Commissioning
High Performance Design Features · Electrical Systems ¨ Automated daylight harvesting controls ¨ Occupancy sensors ¨ High efficiency T-8 bulbs & electronic ballasts ¨ High efficiency transformers ¨ Renewable (Green) energy certificates ¨ Commissioning
Financial Benefits · Integrated facility improvements compound efficiency savings/lower operating costs ¨ Utility Cost Savings in excess of $50, 000/year ¨ Maintenance Cost Savings in excess of $38, 000/year ¨ Cooling requirement reduced by 130 Tons of air conditioning v Results in equipment, installation, electrical and maintenance cost savings
Financial Benefits · Savings funded ¨ High efficiency HVAC systems /building automation system ¨ Lighting controls/daylight harvesting controls ¨ Commissioning ¨ All fees associated with LEED ¨ Green Power Credits ¨ On-going Support Services
Financial Benefits · Base bid for the 750 student/121, 000 sq. ft. middle school facility ¨ $11. 8 M ¨ approximately $97 sq. ft. · An additional $987, 000 was funded through the · · performance contract bridging the gap in the district’s construction budget More valuable building Life cycle cost savings to district $11. 3 million
Operational Benefits · High reliability · Natural daylighting · Improved indoor air quality · Detailed system control · On-going measurement and verification identifies problems while they are still manageable
Student and Teacher Benefits · Healthier, more productive learning environment · Improved acoustic, visual and thermal comfort · Improved attendance · Higher test scores · Improved recruitment and retention of teaching staff
Student and Teacher Benefits · Improved awareness in energy use and environmental responsibility ¨ Building is a teaching tool ¨ Supplement all areas of curriculum v Health, science, social studies, language, and economics
Community Benefits · Wise investment of tax dollars · Community resource ¨ Will stand the test of time ¨ Will experience increased use by community · Evidence of commitment to excellence in education · Evidence of commitment to protecting the environment · Tangible expression of community values
Why High Performance Design? · Results in an optimal learning environment · Conserves natural resources · It makes good financial sense
