Early involvement by key suppliers and experts in evidence-based, green and life cycle design.
Use combined heating, cooling and power systems to meet internal needs with utility back-up.
Agent involvement throughout the design process and periodic retro-commissioning to maintain facility performance over time.
Waste Heat Recovery
Use heat exchangers to recover energy from steam and process water.
VAV Laboratory Control
Use variable air volume fume hood and laboratory systems with occupancy sensing.
Use low flow toilets, faucets and fixtures and motion detectors for sinks.
Collect condensate and gray water for cooling tower, irrigation and toilet flushing purposes.
Heat Recovery in Air-handling Systems
Apply heat recovery systems to allow use of 100% outside air in critical zones.
High Efficiency Lighting
Use CFL’s and T8/T5 lamps with electronic ballasts, occupancy detectors and daylight sensors.
Reduce Frictional Losses in Air/Water System Design
Design for smaller pumps and fans to save energy and capital costs.
Where Emphasize To Get Energy Savings
Windows replacement, Solar Films, Caulking/Sealing, Enhanced insulation, Air leakage Control.
T8 vs. T12 lamps, Compact fluorescent bulbs, Electronic dimmable ballast, Clear lighting sensor, Monitor sensor.
Higher efficiency, Heat recovery, Displacement ventilation, dedicated outdoor Air supply, Geothermal.
BMS application, Maintenance management, Vertical integration.
If your electricity is all green, sustainably sourced 1000 kWh = 0 kg CO2
If your electricity is half green, half gas-fired 1000 kWh = 95 kg CO2
If your electricity is all gas-fired 1000 kWh = 190 kg CO2
If your electricity is half gas, half coal-fired 1000 kWh = 245 kg CO2
If your electricity is all coal-fired 1000 kWh = 300 kg CO2
If your electricity is nuclear 1000 kWh = 45 kg CO2
Green electricity is solar, wind, hydro, geothermal, etc.
Some large-scale hydro may produce large amounts of methane, but the results differ and no data has ever been collected on a dam by dam basis.
The full nuclear fuel cycle produces about 15% the emissions of a coal-fired power plant.
KWh per Building.
Our electricity produces _____ kg of CO2 per 1000 kWh (B).
Result (A x B) = ________ kg of CO2 from your use of electricity
Lower consumption kW means lower cost and CO2 emissions to the atmosphere.
60,000 btu/h x 3000 hrs x $0.18kWh/10 SEER = $3,240 yr
14 SEER = $2,314 yr.
10 SEER releases 3.14 kgh CO2 /
14 SEER releases 2.24.
12500 miles / 21.5mpg = 580 gallons = 2200 liters = 5000 kg CO2 per car per year.
The following factors can be taken into account in home’s bill:
Your annual electricity consumption in kWh.
Your annual gas consumption in kWh based on your annual usage.
Any oil consumption in liters per year.
Emissions of carbon dioxide (C02) based on the fuel* (this is the Fuel Conversion).
An example calculation would be:
3000 kWh per year electricity usage x 0.523 kg CO2 per kWh* / 1000 =1.569 +
(5000 kWh per year gas usage x 0.185 kg (CO2) per kWh* / 1000) = 0.925
Total 1.569 + 0.925 = 2.494 tCO2[/vc_column_text][/vc_column][/vc_row]
