By understanding why increasing energy consumption for space cooling is a growing concern, we can properly develop effective policies and deliver efficient technologies.
The five main reasons space cooling demand is on the rise include:
Broadly there are two key space cooling opportunitities:
While many discussions start with the goal of reducing the energy used for cooling, long-term benefits can also be achieved by increasing cooling thermal comfort while reducing the need for space cooling. Both opportunities enable multiple benefits: lower energy bills, fewer electricity capacity constraints and less use of climate-warming refrigerants.
Key areas for energy efficiency policy are:
Key technologies are insultation, shading, windows and efficient air conditioners.
The choice of energy efficiency policies and technologies to address space cooling demand should be made using life-cycle calculations that account for the multiple benefits of energy efficiency. Policies and technologies should enable greater increased thermal comfort while reducing the total energy consumed.
