U.S. Energy Flow, 2005 (Quads) 86% of primary energy is from fossil fuels, with 69% of the petroleum imported Domestic Supply Consume 67% Fossil 104 100 86% Quads Industrial Quads 32% Imports Nuclear 8% 33% Renewable 6% 3 Philips Research North America, Satyen Mukherjee, Oct 13, 2011 3

Definitions ZEB or ZNEB: Zero Net Energy Building Produces more energy on-site than it consumes, on an annual basis. – Excludes: - Transportation - Embodied Energy in Water, Materials, Waste • Net-zero site energy • Net-zero source energy • Net-zero carbon • Net-zero energy cost Zero Energy Buildings: A Critical Look at the Definition P.Torcellini, S. Pless, M. Deru - NREL D. Crawley - DoE 2006 www.nrel.gov 4 Philips Research North America, Satyen Mukherjee, Oct 13, 2011

Challenges • Wide range of building types • Variability in requirements – geographical, weather • Drift over time • Economic Performance • Flexibility/Adaptability to Changing Needs • Balancing Energy Consumption with Occupant Comfort and Productivity 5 Philips Research North America, Satyen Mukherjee, Oct 13, 2011

Commercial building types 40-90% energy savings needed 6 Philips Research North America, Satyen Mukherjee, Oct 13, 2011

Commercial Buildings Site Electricity Consumption by End Use Lighting +Cooling +Heating +Ventilation = 68% Site Electricity use 7 Philips Research North America, Satyen Mukherjee, Oct 13, 2011
