The Library Expansion project has been committed to Energy Efficiency since the beginning of the project. Recognizing the new building would need to last another 50 years, it was important to coordinate design and cost with energy-saving choices.  A presentation was made to City Council by Skyler Swinford of Energy System Consultants in

McCall Public Library Board of Trustees, Building Committee, Humphries Poli and CM Company are all committed to the application of design and building techniques that promote reduced energy consumption and decreased environmental footprints. In addition to being a conscious choice, sustainable design applications are expected to enable realization of immediate and long-term economic benefits.

Because libraries consume large amounts of energy and resources, and because they affect the quality of lives in their communities, this project is highly appropriate for green building principles. According to Humphries Poli, the biggest misconception about green architecture is the assumption that it is more expensive. Often the tendency is to add things like a green roof or solar panels. But there are ways to reconfigure the guts of a building without spending more than traditional construction costs. The following tools and techniques are employed at the McCall Library project to ensure it will continue to perform well in the future:

  • Sustainable site strategies
  • Passive solar building design
  • Daylighting
  • Recycled materials
  • Rapidly renewable / low maintenance building materials
  • Xeriscaping

Energy modeling of design alternates and review of cost/benefits on energy use systems will ensure this project is “cheap to keep.” Humphries Poli is engaging an energy systems consultant. The proposal includes:

  1. Establishing preliminary building performance goals
  2. Developing a whole building energy model
  3. Evaluation of passive design strategies such as thermal mass, shading, natural ventilation
  4. Evaluation of thermal enclosure specifications
  5. Providing optimal performance targets and recommended assemblies/systems (roofs, wall, windows/doors, floors and air-barrier to minimize heating and cooling loads
  6. Evaluation of low-energy mechanical systems (cold climate heat pumps and high efficiency E/HRVs)
  7. Recommendation of best practices and targets to minimize indoor lighting loads, plug/process loads, DHW distribution losses, fan/pump energy, and outdoor lighting loads
  8. Guidance for renewable energy systems sizing and costs
  9. Recommendations for HVAC and building performance monitoring
  10. Providing economic comparison of code/design baseline and ‘optimal’ high-performance design option
  11. Providing hygrothermal analysis of unconventional building enclosure assemblies for long-term durability
