[Project] The GBPN and REEEP Launch the “1 Billion Square Meters” Initiative: An effort to Promote Residential Positive Energy Buildings

2013/05/21 | Global全球South-East AsiaSouth-East Asia

The GBPN and the Renewable Energy and Energy Efficiency Partnership (REEEP) announced today at the EE Global Intensive Learning Session in Washington, D.C. the launch of a new collaboration aiming to encourage the construction of 1 billion m2 of positive energy and affordable social housing by 2023. 

Designed to promote energy efficiency in buildings in emerging economies in the residential sector and engage with global actors in the field, “1 Billion m2” sets a work programme that will help deliver the United Nations’ Sustainable Development Goal on energy.

The project’s main challenge consists in reversing the mainstream trend around building performance by making buildings become net energy providers, instead of energy users, in all climates and for all consumers, rich and poor.

“Buildings can become answers to the global energy supply questions. What is needed in our view is a global movement that decides to change the ‘buildings paradigm’. It is time for buildings to play a major role in their ecosystem towards developing ecological positive built environments. “, said Peter Graham, Executive Director of the GBPN.

To achieve its mission, “1 Billion m2” will develop:

  • Technical and practical tools, knowhow and training for the construction of energy positive buildings in key countries and ensure their use;
  • A community of practice, bringing together actors in the field of social housing who stand up and are counted for a future in which buildings are net energy contributors.

By combining REEEP’s expertise and network of implementing organisations with the GBPN’s capacity to identify, verify and share international best-practices, “1 Billion m2” aspires to initiate leading edge positive building strategies to create adapted, sustainable and scalable buildings and energy supply.



Based in Vienna, REEEP is a non-profit organisation that aims to accelerate the marketplace for renewable energy and energy efficiency in developing countries and emerging markets. As a market catalyst, REEEP acts as a funder, information provider and connector for up-scaling clean energy business models.

A positive energy building is a building that on average over the year produces more energy from renewable energy sources than it imports from external sources. This is achieved using combination of small power generators and low-energy building techniques such as passive solar building design, insulation and careful site selection and placement.

A building should be regarded as a residential building when more than hald of the floor area is used for dwelling purposes. Other buildings should be regarded as non-residential. Two types of residential buildings can be distinguished: 1.) Houses (ground-oriented residential buildings): comprising all types of houses (detached, semi-detached, terraced houses, houses built in a row, etc.) each dwelling of which has its own entrance directly from the ground surface; 2.) other residential buildings: comprising all residential buildings other than ground-oriented residential buildings as defined above.
