International Outlook for Energy Efficiency in Existing Buildings
© OECD/IEA 2015
The start of a new energy era?
Universal agreement from COP21 is an historic milestone that can stimulate energy sector innovation
Pledges of almost 190 countries account for almost the entire energy-related emissions
Renewables capacity additions at a record-high of 130 GW in 2014
2015 has seen lower prices for all fossil fuels
Oil & gas is facing second year of falling upstream investment in 2016
Coal prices remain at rock-bottom as demand slows in China
Multiple signs of change, but are they moving the energy system in the right direction?

Efficiency measures on the rise, but significant potential still exists
Share of global mandatory efficiency regulation of final energy consumption
Energy efficiency policies are introduced in more countries and sectors; they continue to slow demand growth but more can be done

More than half of energy reductions needed in the 450 scenario come from heating and cooling

Policies needs diverge by region
Residential floor area by region in 2040
Retrofit is key in OECD regions, while codes for new buildings will shape future energy consumption in emerging economies

Global Residential Floor Area Growth to 2050 (6DS)
In a 6DS world, we would expect continued high levels of non-compliance in building construction and marginal retrofits of existing stock

In a 2DS world, far smaller levels of non-compliance and high levels of deep retrofits will contribute to significant energy reductions
