Stationary Energy End-Use Sectors A number of assumptions for these sectors are based on estimates by Odón de Buen, energy efficiency expert. The assumptions for the interventions that address the commercial and service sectors (nonresidential buildings) are included in table C.6.

Source: Based on data from NRCan (2007), adjusted for Mexico, and authors’ assumptions. Note: Figures assume 10 hours per day of air-conditioning use for all building types. AC = air conditioning.
Nonresidential Air Conditioning
• Program definition: Install efficient air conditioning in all nonresidential buildings • Project duration: 30 years (equal to air-conditioning lifetime) • Demand per ton of standard air conditioning: 1.7 kW • Demand per ton of efficient air conditioning: 0.9 kW • Cost per ton of efficient air conditioning: $1,140 • Time for implementation of full program: 10 years • Air conditioning lifetime: 30 years
