For more than 30 years, the Pacific Northwest has successfully pursued state residential energy codes and building programs to create ever more efficient housing. Since its inception, the Northwest Energy Efficiency Alliance (NEEA) has played a pivotal role in aiding states to deliver more effective and efficient energy codes.

Extensive analysis over the last decade has demonstrated that in developed economies energy use in buildings is one of the most significant contributors to aggregate greenhouse gas emissions. More significantly, reducing greenhouse gas emissions from the building sector provides a range of social and economic benefits in addition to anticipated environmental benefits.

Mandatory civil building energy efficiency codes strictly govern the energy consumption of new buildings in China. As the promotion of building energy efficiency in China has increased in recent years, compliance with mandatory civil building energy efficiency codes has also improved, increasing from less than 10% in 2000 to nearly 100% in 2012, a remarkable achievement.

Environmental issues, costs, and limited energy supply, among other concerns have been driving the efforts toward more energy efficient buildings over the last four decades. Hence, energy efficiency is not only well-established within the building design and construction industries, but is also an active field of research.

For promoting energy-efficient building design, various green building certification schemes such as BREEAM, LEED, DGNB, Green Mark, BEAM Plus, ASHRAE Standard 90.1, Code of Practice for OTTV, etc. have been developed around the world. In recent years, photovoltaic system is widely adopted in building application.

This white paper examines the current state of zero energy codes and provides an update on avenues to achieving zero energy codes by 2030. It presents an overview of current efforts to achieve zero energy and similarly high-performing buildings, example code proposals that help move the needle toward ZEBs, and thoughts on additional issues and barriers.

Modern residential building energy codes provide a component tradeoff mechanism by which builders can trade reductions in the efficiency of some building components in trade for corresponding improvement in other components. One common tradeoff approach is based on maintaining a building "UA value," which represents the building envelope's overall thermal conductance.

Heat recovery ventilators (HRVs) save energy by recovering heat that would otherwise be exhausted as part of energy code-mandated mechanical ventilation systems. Residential HRVs can be life cycle cost effective depending on equipment/installation costs and the severity of the climate.

In 2017, New York State Energy Research and Development Authority (NYSERDA) developed its 2016 Stretch Code Supplement to the 2016 New York State Energy Conservation Construction Code. Since 2017, NYSERDA has continued to develop the 2018 edition, as part of the efforts to achieve a statewide Net Zero Energy Code by 2028.

The buildings sector contributes nearly 40% to global energy-related annual GHG emissions (IEA/UNEP, 2018). Final energy demand from buildings is predicted to increase 50% by 2050 compared with 2015 levels under business as usual scenarios due to rapid urbanisation and the doubling of the built surface area.

Improving the performance of buildings must be a central component of any response to the challenges of climate change. This is both an imperative and an opportunity.

Building energy codes lay out the minimum requirements for the envelope (insulation, windows and air sealing), mechanical equipment and lighting of a building (residential and commercial) in terms of energy efficiency/conservation for new construction or major renovations.
