Green Building Council of Namibia Glenn Howard – Emcon Consulting Engineers
The case for energy management in buildings ◦ Why? ◦ How much? Do we use? Can we save? ◦ Where can we save? ◦ What is the process?
Sustainability ◦ Reduce greenhouse gas emissions ◦ Reduce consumption of finite energy resources ◦ Migrate to infinite energy resources Green Star Rating ◦ Demonstrate commitment to sustainability ◦ Provides a rigorous methodology Business case? ◦ Is there a business case? ◦ If so, we have a winner that gets the horse (building owner) to drink from the eternal river
Existing Building Performance (Pilot) “Energy” category points = 27% of rating: ◦ Energy reduction – related to GHG emissions (25 points) ◦ Peak electricity demand reduction (2 points) Add “Building Management” and “Water” = 44%
Energy source (electrical, gas, diesel, paraffin, solar, wood) Air conditioning (HVAC) and refrigeration Lighting ◦ Efficiency (luminaire and lamp) ◦ Control ◦ Daylight ◦ Illumination levels Water heating Appliances ◦ Industrial engineering ◦ Energy rating (TCO – LCC) Elevators & escalators Computer energy saving modes Power factor correction Renewable energy MAINTENANCE (Scheduled maintenance) Etc.
When? ◦ New building – get it right first time ◦ Existing building – any time or at trigger points: sale of the property change in the lease replacement of equipment refinancing, remodelling, renovation or rehabilitation
Goals ◦ Lowest cost of energy ◦ Efficient energy use ◦ Use most appropriate technology Ultimate goal ◦ Sustainability ◦ Zero net energy (ZNE) buildings
Systematic assessment of energy use ◦ Sources ◦ Where it is used ◦ Variance between input and useage ◦ Effectiveness and efficiency
Broad organisational awareness Monitor and measure Energy management plan – short & long term Integrated into organisation management structure Provide leadership (Champion) and a team Top-down commitment expressed as policy
Energy is a manageable expense You can’t manage what you don’t measure (and report on) Thank you
