[Report] Best Practice Building Codes: Insights from Policy Makers

28-07-2014 | GlobalSouth-East AsiaSouth-East Asia

The new Policy Paper released today captures the main findings of the dialogue initiated by the GBPN with practitioners and international code experts on the design and implementation of best practice building codes. It provides an insight into the practical aspects of developing best practice building codes along with a number of recommendations on how code developers can strengthen progressive buildings codes in future.

This dialogue was facilitated through a webinar series hosted by the GBPN in partnership with the Clean Energy Solutions Centre between September 2013 and February 2014 (Video recording). The report provides an insight into the practical aspects of developing best practice building codes along with a number of recommendations on how code developers can strengthen progressive buildings codes in future.

The GBPN research shows if we are to achieve significant CO2 mitigation in the building sector, new buildings must be developed to zero energy standards. Despite increasing awareness of the need for such standards, the practical knowledge about “how to” develop and implement them is often missing.

In 2013 the GBPN developed an on-line policy tool to facilitate the interactive analysis and comparison of twenty-five best-practice building codes for new buildings using specially developed criteria. To support a deeper understanding of the “how to” of code development , the GBPN hosted a series of webinars featuring a number of policy makers from best practice regions included in the tool. 

The three webinars focused on the themes of “Long-Term Energy Targets and Frequent Revision Cycles”, “Performance Based Approach to Code Development” and “Good Enforcement” as the analysis from the tool highlighted scope for further improvement in these areas. Speakers were asked to provide insight into the main drivers for the development of progressive building codes in their jurisdictions and to outline the barriers and opportunities as well as the key lessons learnt. By sharing critical insights, the GBPN hopes to support countries to develop policies that help them to make a structured and impactful transition towards zero energy buildings and positive buildings.

It is clear from this paper that every jurisdiction has its own specific regional differences but there are a number of key messages that have emerged under the different themes that apply to all jurisdictions irrespective of location or political context.

Glossary

A certificate recognised by a Member State or by a legal person designated by it, which indicates the energy performance of a building or building unit, calculated according to a methodology adopted in accordance with Article 3 [Source: EPBD recast, 2010/31/EU].

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.]

Energy performance requirements are based on a building’s overall consumption of energy or fossil fuel or the building’s implied emissions of greenhouse gas. [Source: Laustsen (2009) Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings]

A collection of policies and programmes that support the implementation of a common goal.
