The positive energy buildings laboratory seeks to develop interactive support for the development of roadmaps for positive energy buildings. The laboratory aims to do this by building on the lessons learned from GBPN's comparative study of building energy efficiency codes and policy packages for new buildings (residential and commercial). The study highlighted two key areas that require further research in order to ensure the accurate comparison of building codes and increased compliance with those standards.  

Two key issues emerged from the comparative study:

  • the need to develop overall performance values for all codes to ensure the accurate comparison of those codes and,
  • the need for further improvements in compliance regimes for the enforcement of building energy efficiency codes.

Over the coming months we invite you to participate in the discussions surrounding these topics and to contribute your valuable thoughts and ideas to the process. We hope that by sharing our work on this platform that we can promote a constructive dialogue amongst the expert community on these important topics. The open nature of this process also ensures the transparency of our work and ensures its rigor by discussing these ideas with the experts. Initally the main focus of this lab will be on the development of overall performance values. However, in the coming weeks we will expand the discussion to include compliance.

To make a contribution, please use the forum Overall Performance Values - Building Codes

Niamh McDonald, GBPN Building Policy Analyst is responsible for moderating this Laboratory. If you have any questions or queries relating to the lab please feel free to contact her.

Glossary

NZEB are buildings that over a year are neutral, meaning that they deliver as much energy to the supply grids as they use from the grids. Seen in these terms they do not need any fossil fuel for heating, cooling, lighting or other energy uses although they sometimes draw energy from the grid. [Source: IEA (Laustsen J.) (2008) Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings.]

A net zero emissions building produces at least as much emissions-free renewable energy as it uses from emissions producing energy sources. [Source: Torcellini et al. 2006]

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.

Zero Energy Buildings are buildings that do not use fossil fuels but only get all their required energy from solar energy and other renewable energy sources. [Source: IEA (Laustsen J.) (2008) Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings.]
