6 The Rise and Fall of Fuel Cells dpoint founded in late 2004 Began investigating other opportunities 6

7 Opportunity: Energy Recovery Ventilator (ERV) Exhaust Air (Cold & Dry) Fresh Air (Hot & Humid) ERV Core ERV System 7 -Reduce Electricity and Gas Consumption of HVAC Systems, -Allow Smaller Air Conditioners to be Installed -Provides Better Indoor Air Quality

8 Building Energy Efficiency 8 Buildings Consume 48% of Energy in the US 8

9 Heating, Ventilation and Air Conditioning HVAC Systems Consume 45% of the Energy in Buildings 9 9

10 Air Tight Buildings Ventilation is Necessary as Buildings Become Air Tight 10

11 Sick Building Syndrome Contaminants such as VOCs, airborne bacteria and formaldehyde need to be exhausted from the building 11

12 Trends in Energy Recovery Codes & Standards ASHRAE : 50% total energy recovery required in commercial buildings. States must adopt by Oct City Building Codes: Heat recovery ventilation required in all Vancouver homes, New Ontario building code Europe: 70-90% Heat recovery required in most buildings Leed: Points for ERV from energy conservation and indoor air quality Passivhaus: Ventilation and Heat Recovery are required Energy Star: ERVs are now energy star rated 12 Rapid Growth in Energy Recovery from Codes and Building Labeling Programs

13 ERVs vs HRVs ERVs Higher energy savings (latent & sensible) Capital savings of AC Equipment Better comfort controlling humidity 13 HRVs Higher sensible performance Buildings requiring dehumidification (pools) First year after construction (dehumidify)

14 Fixed Plate ERVs vs Enthalpy Wheels Fixed Plate ERVs Less Maintenance (no moving parts) Lower Air Cross-Over (no seals, separation of air streams) Lower Energy Consumption Enthalpy Wheels Typically more compact Higher latent effectiveness 14

15 ERVs Save Energy and AC Capital Cost in Warm Humid Climates In a typical summer application, AC units use a lot of energy removing heat AND moisture from the air 30% of energy used to remove heat 70% of energy used to remove moisture A dpoint ERV core removes up to 60% of the moisture so that the air conditioner can be smaller and use less energy An ERV has much higher total effectiveness in summer conditions Sensible Effectiveness Latent Effectiveness Total Effectiveness Counter-flow HRV 90% 0% 34% Counter-flow ERV 75% 60% 66% 15

16 ERVs Provide Comfort and Energy Savings from Less Humidification in Winter Occupant comfort is negatively affected from buildings being too dry in winter HRVs bring dry air in and exhaust humid air ERVs recapture the humidity 16 Dry Lips Dry Skin

17 ERVs in Cold Climates Case Study: Canadian Centre for Housing Technology Two identical houses were evaluated at -5 C to -19 C outdoor air Baseline utilized an HRV core; Test house utilized a dpoint ERV Core The ERV core recovered 2.5L/day more moisture than the HRV core at 30% indoor humidity The HRV core produced significant amounts of condensation under all conditions. The ERV core never produced any condensation The amount of humidifier water required by the Test House was reduced by the ERV core. The ERV core showed no signs of degradation after seven days of cold weather testing, immersion in water for three hours for cleaning, and ten additional days of cold weather testing. The ERV Core had higher higher sensible, latent and total effectiveness than the HRV Core 17 Sensible Eff Latent Eff Total Eff HRV 63% 0% 51% ERV 66% 38% 61%
