Innovation, Sustainability, and Historic Buildings – The Blog for Preservation Leadership Forum

I recently read an article that highlights how energy-efficient systems can be integrated into a historic building in a low impact way. GSA Rocky Mountain Region, Design-Build Partners of The Beck Group, and Westlake Reed Leskosky ‘s renovation of GSA’s Wayne N. Aspinall Federal Building and U.S. Courthouse in Grand Junction, Colo., illustrates how reducing occupant’s plug loads, accounting for all energy uses, implementing innovative technologies and sustainable models can be implemented in a historic building . An important item to note that is often overlooked is the reduction of energy demand, which allows for installation of downsized HVAC systems and ensuring a better fit within existing building structure.

The article highlights the following implemented measures:

  • Variable Refrigerant Flow (VRF) Systems
  • Dedicated Ventilation Systems
  • GeoExchange
  • Reducing Energy Demands

Exploring the Future of Wind and Hydrokinetic Energy

Hydrokinetic power is attractive due to its abundance, particularly near population centers. It is estimated that 370 TWh/yr (terawatt-hours per year) of hydrokinetic power is available from rivers and tidal currents in the United States, which equates to about 9% of the total annual U.S. energy demand. An additional 1,170 TWh/yr (29% of US energy demand) is available from wave power “–Q&A with Dartmouth’s Brenden Epps
