Wisconsin Union Building Project

The building must be a people magnet

The building advances programming

The architecture is timeless and enduring

The building process and materials are green& sustainable

The facility is student-focused, but welcoming of allThe building is a draw for the entire campus while reflecting the interests & needs of its local neighborhood

The building is complementary to Memorial Union, not supplementary

The facility tells the Union story.

Principles

Close Union South after student finals December 2008 Transition to interim space: Breese Terrace Union

January 2009 Begin demolition: Union, Hi-Ray & Randall Towers Spring 2009 Construction will follow and extend through March 2011 Host the National Science Olympiad May 2011

What is Sustainability?• Definition: meeting the needs of the present

without compromising the ability of future generations to meet their own needs EPA website

• How does sustainability relate to a major building project?– Buildings account for 40% of total global

energy use• How has the new south campus

union approached sustainability?

“Big Ass Fans”:Help pull up hot air in summer and push it down in winter

Local & Salvaged Materials

• Salvage Registry provides a palette of material selections, giving the architects an opportunity to integrate historical materials into the new building

• Emphasis on local materials supports local economy, reduces transportation energy, and helps reflect local heritage

Daylighting

Preliminary energy model results indicate 37% better thanASHRAE 90.1-2004 requirements. Included:

Multiple VAV Air Handling Units High Performance Glass Optimized Wall and Roof Insulation Optimized Daylight Strategies – shading devices, glare control Heat Recovery Demand Control Ventilation Lighting Power Reduction Day Lighting Controls Natural Ventilation in the Grill w/ manual Natural Ventilation in the Wintergarden w/ manual controls Displacement Ventilation in Theater

• Refrigerant Heat Recovery from Food Service Walk-Ins

Energy Conservation

Additional Strategies being studied include: Demand Control on Kitchen Hoods Refrigerant Heat Recovery from Food Service Walk-Ins Wastewater Heat Recovery from Dish Machine Solar Photovoltaic System Dual Path Dehumidification Increased Day Lighting Energy Savings Wind Power

Energy Conservation

Strategies being studied include: Dedicated Parking for low-emission and fuel-efficient

vehicles to promote clean air Drought tolerant native landscaping to conserve water and

support local habitat Alternative transportation: 2 bus stops within ¼ a mile (one

across the street) and 230 bicycle stalls Other potential future alternative transportation options

include regional bus service, commuter rail, and alternative fueling stations in the parking structure

Maximized open space equal to 20% of site area Materials to reduce heat island effect

Sustainable Site

Strategies being studied include:Preliminary calculations using LEED templates indicate the facility could achieve a 40% water reduction

High-Efficiency Irrigation SystemStormwater cistern to capture rainwater from the roof to be used for irrigation and/or flushing toiletsLow-flow water urinalsDual-flush toiletsLow-flow lavatory faucetsLow-flow shower heads

Water Efficiency

Strategies being studied include: Construction Recycling to divert construction waste from the

landfill (percent TBD) Carpet, ceiling tiles, rubber flooring and other materials with

recycled content to reduce pressure on landfills and lessen demand for natural resources

Regional materials harvested and manufactured within 500 miles of the project site, but are focusing more so on Wisconsin-based materials and resources

Certified wood in accordance with Forestry Stewardship Council

Materials & Resources

Strategies being studied include: No smoking around building to protect indoor air quality Interior finishes with low VOC-emitting components to

maintain indoor air quality Lighting with daylight controls Task areas that have direct access to views of the outdoors

Indoor Env. Quality

Strategies being studied include: An outreach program to educate our community, our

colleagues and our industry about the benefits of sustainability in the built environment

A comprehensive green housekeeping program to eliminate the use of toxic chemicals

A Transportation Management plan that shows a reduction in single occupancy vehicle use

Other various design innovations still to be determined Salvage Registry to extend the idea of a 100-year building

into the past
