  25. 25. BMPs: Immediate and Easy Building EvaluationWalk-through: A tour of the building during different operational periods (i.e. during business hours, after hours, during major events).• Take note of the following: – Lighting – Electronic equipment – Temperature/humidity – Noticeable building damage – Staff expertise and knowledge• Pros and cons: – Pros: self-guided, low cost, many low cost opportunities – Cons: technical opportunities will likely be missed www.CleanEnergyResourceTeams.org
  26. 26. BMPs: Immediate and Easy No/Low Cost PracticesLighting – No Cost • Turn off when not in use! • Daylight – Use sunlight when available and arrange furniture so that sunlight does not cause glares. • Delamping - Evaluate how much lighting individuals need to work and remove unnecessary lamps. U of M light switch Daylight-lit room Delamped lamp sticker reminder www.CleanEnergyResourceTeams.org
  27. 27. BMPs: Immediate and Easy No/Low Cost PracticesLighting – Low Cost • Automatic lighting controls - Use occupancy sensors, especially in bathrooms, closets, hallways, or other occasionally used areas. • LEDs – Use especially in “Exit” signs and security lights that must always be on.

  38. 38. BMPs: Longer term & more effort Building Evaluation• Recommissioning: “A systematic process to improve the operation of your building systems so that they: • Actually meet your needs (for ventilation, comfort, air quality control) • Use only as much energy as is really necessary to do so.” Center for Energy and the Environment4 www.CleanEnergyResourceTeams.org
  39. 39. BMPs: Longer term & more effort Building EvaluationRecommissioning - So how does it work?• “Calibration: ensure control sensors and devices are calibrated• Scheduling and Enabling: Turn equipment off or down when unneeded• Air and Water Flows: Don’t run equipment at higher air or water flows than needed• Ventilation: Make sure the right amount of ventilation air gets in, and that it gets to where the people are.• Setpoints and Resets: Don’t run equipment at higher heating or lower cooling temperatures or higher air or water pressures than needed• Condition and Function Checks: Make sure key equipment is working the way it should (actuators, dampers, valves, VFDs, etc.)” Center for Energy and the Environment4 www.CleanEnergyResourceTeams.org
  40. 40. BMPs: Longer term & more effort Building EvaluationRecommissioning – In-house experts• Use talents and knowledge of current maintenance staff• Capacity building - consider investing in building management training courses for staff – Practices in the building industry are constantly evolving – Extra training helps provide and ensure proper energy management over the long term – Utilities might help with training costs – just ask! www.CleanEnergyResourceTeams.org
