2 The Existing Building Pre-Renovation Built in 1903 by John S. Pillsbury, former Governor of Minnesota to be gifted as a public library Beaux Arts style is characteristic of public and cultural institutions built during this time period National Register of Historic Places Contributing Structure to St. Anthony Falls Historic District More recent use as laboratory and art gallery Historic interiors had been repeatedly altered and nearly all original materials removed prior to renovation Postcard circa 1916

3 Preservation Strategies Restore damaged portions of exterior, specifically balusters/balustrade Maintain spatial layout of original library building Preserve existing interior details and match new details to existing Site restoration as green oasis in high density; asphalt jungle Plaster work above ceiling - before

4 Skylights Skylights found during demolition of interior. Restored by local artists and reinstalled in the coffers of the central hall ceiling Resored Skylights Central Hall Before Central Hall Before Renovated Central Hall

5 Skylights Mysterious Symbols Does anyone know what they mean??

6 Windows New Windows Conference Room Windows before Office

7 Balusters Renovated Front Facade Front Facade before New Balustrade

8 ADA Accessible Entrance Addition of new entrance and elevator to meet ADA requirements Designed to complement existing building proportions and rhythm New ADA Entrance Rear of Building before New ADA Entrance

9 LEED Strategies Update HVAC Systems with efficient systems, and Energy Star appliances Low flow fixtures in bathrooms and kitchen Reduce amount of paving to minimum necessary, add rain garden to catch parking lot runoff Low VOC Finishes Daylighting of spaces Cool roof Regional Materials Waste Reduction Plan Office Kitchen

10 Landfill Diversion & Water Use Reduction Project removals diverted from landfills is 91% Reduced water consumption is projected 47% by using low flow fixtures Restroom Recycling dumpster Restroom

11 Heat Island - Roof Roof after - High albedo roof membrane Black membrane roof was replaced with white roof and insulation added How many guys does it take to...? Roof before - Low albedo roof membrane

12 Reduction of Impervious Surface 100% storm water retention and infiltration on site by removal of asphalt alley, smaller parking lot design and rain garden Asphalt everywhere - before Rain Garden Reduced impervious surface

13 Lessons Learned from this Project Integrated Design Process: LEED must be considered from the outset as a part of the initial design strategy in concert with preservation strategies Contractual obligation (liability) for indifference to certification must be set out in writing LEED must be utilized as an approach to design, not an aesthetic RESISTANCE IS FUTILE!

14 Lessons Learned from this Project - Teamwork Owner: The Phillips Family Architect: Domain Architecture& Design Interior Designer: Gunkelman Flesher GeneralContractor: Ryan Companies US, Inc Historical Consultant: Landscape Research Structural Engineer: Mattson McDonald Young Mechanical Engineer: Yale Mechanical Lighting Design: Schuler Shook Electrical: Fraser-Morris Electric Company Plumbing: Horwitz Plumbing Masonry: Advanced Masonry Restoration Stained Glass: Gaytee Stained Glass Windows: United Glass & Glazing Painting: Swanson & Youngdale Waste Mgt./Landfill Diversion: Atomic Recycling Heat Island Roofing: B.L. Dalsin Roofing FSC Millwork: Osvold Company FSC Flooring: Schaefer Hardwood Floors Plaster Restoration: Olympic Wall Systems

15 Energy Conservation in Historic Buildings - Best achieved through an integrated design process - Buildings used to be designed more sustainably. - Look for the opportunities year materials - Excellent daylight distribution (hidden skylights) - Heavy thermal mass - Natural ventilation opportunities - Passive solar heating opportunities

16 Energy Conservation in Historic Buildings The Phillips building (existing building/renovation) - Achieved 18.9% reduction in energy costs % reduction in energy use - Earned 5 LEED-NC 2.2 points (~12% of all LEED points earned) - Improvements achieved in: - Roof, wall, and glazing thermal performance - Lighting controls - Exterior lighting improvements - Extremely efficient mechanical heating and cooling systems - Demand controlled ventilation - Also achieved an additional point in Measurement and Verification

17 Energy Conservation in Historic Buildings Lessons Learned - Bring in your energy consultant at the project inception - Set energy efficiency goals early in the pre-design phase - Make sure each discipline understands their contribution to the energy efficiency picture - Confirm that all disciplines are on board with energy efficiency goals - Get all ideas out on the table early, otherwise opportunities might be missed - Consider energy goals, project costs, available technologies, and Owners Project Requirements - Check the design prior to the SD, DD, and CD phases to ensure energy efficiency goals are being met - Work closely with the Commissioning Authority to be sure that installed equipment meets design specifications Thank you Veterans!
