Building Standards Compared

The paper seeks to illustrate clearly how the choice of selecting a building standard affects the amount of renewable energy generation that is required to comply with a net zero operational outcome. The report does not take into account embodied energy/carbon. All energy and carbon modelling is illustrative but based upon real archetypes.

Assured Performance Process (APP)

What is the Assured Performance Process (APP)?

There is often a huge difference between how buildings are supposed to perform, and how they actually do.  The assured performance process provides independent and expert input to the development process to minimise this energy, overheating, and indoor air quality performance gap.  As well as helping to reduce carbon emissions and climate change, this improves the health of people using buildings.

The Assured Performance Process TM (APP) maps to the RIBA Plan of Work and has five stages of expert, impartial review and assessment. APP assessors are accredited by The National Energy Foundation for their expertise and they offer two services:

  • APP implementation across all five key stages – supporting the client throughout the development process. This is a bespoke service.
  • One off reviews tailored to the stage of the development

Who is behind APP?

The Good Homes Alliance has secured a two year license for the Assured Performance Process (APP) from the original developer and owner, the National Energy Foundation (NEF).

NEF is a charity which has been meeting its mission of “improving the use of energy in buildings” for more than 20 years.  NEF has established other nationally recognised quality systems.

Right to Build Toolkit

The Right to Build toolkit has been developed by the Right to Build Task Force, a professional advice service, and part community-interest company, that supports a range of organisations in their ambitions to deliver more Custom- and Self-build homes in the UK. The Task Force is supported by a team of experts able to provide advice to help unlock the growing demand from people that want to build, or commission, their own home.

Although set up by the National Custom and Self Build Association (NaCSBA), the Task Force operates completely independently, with an ethical wall between the two organisations. This is because while NaCSBA lobbies government for change, the Right to Build Task Force is solely focused on providing advice to a range of stakeholders to bring on more owner-commissioned homes, including community-led homes, working within the framework of the Right to Build legislation.

Easi Guide to Passivhaus design

Levitt Bernstein, alongside sustainability engineers Etude, have campaigned tirelessly for faster change in the built environment to achieve zero carbon. But they have found that often the best way to effect change is to collaborate with others, lead by example and share learning along the way.

They believe that the first step to zero carbon is to create an ultra-efficient building design. Through their project work with Etude, they have discovered that the benefits of low energy design can be unlocked by viewing Passivhaus considerations as an opportunity, rather than a constraint.

This led them to develop the ‘Easi Guide to Passivhaus design’, which has been endorsed by the Passivhaus Trust.

The guide graphically sets out ten simple principles that form the foundations of good Passivhaus and zero carbon design. They encourage clients to use it to set their briefs and architects to use it when designing their buildings. The main body of the guide emphasises key considerations at RIBA Stage 2 to allow design teams to meet Passivhaus within the contextual needs of their site, while a checklist offers the next steps if full certification is to be pursued.

By providing open access, they hope that you enjoy our guide, make many zero carbon buildings and share your learning with others.

31 Climate Actions for Councils

Ashden and Friends of the Earth, with the support of CDP, have put together an evidence-based list of the most effective actions councils can take on climate. This easy-to-use list highlights the co-benefits for each action, whether it be better health, improved economy, increased equity or resilience.

Climate Emergency Design Guide

We are in a climate emergency, and urgently need to reduce carbon emissions, this guide outlines the requirements of new buildings to ensure our climate change targets are met – setting out a definitive journey, beyond climate emergency declarations, into a net zero carbon future. It is specifically aimed towards developers/landowners, designers, policy makers, and the supply chain. It aims to help to define ‘good’ and to set clear and achievable targets.

The Climate Emergency Design Guide covers 5 key areas: operational energy, embodied carbon, the future of heat, demand response and data disclosure. Our methodology includes setting the requirements of four key building archetypes (small scale residential, medium/large scale residential, commercial offices, and schools). The guide was developed by over 100 LETI volunteers over a period of 12 months.

This guidance demonstrates that the building industry knows how we should be designing buildings. In 2020 buildings that adopt these requirements now will be seen as leaders. By 2025 these requirements must become standard design practice otherwise the building industry will not meet our collective responsibility in this climate crisis.

LETI believe that in order to meet our climate change targets, in 2020 10% of all new projects developers and designers are involved in, should be designed to meet the requirements set out in this guide.

Embodied Carbon Primer

The Embodied Carbon Primer offers supplementary guidance to the Climate Emergency Design Guide, for those interested in exploring embodied carbon in more detail. There is a current lack of knowledge in the built environment industry surrounding embodied carbon reduction strategies and calculations. Therefore, the London Energy Transformation Initiative has produced this document to support project teams to design buildings that deliver ambitious embodied carbon reductions.

The document can also aid planners to be aware of strategies available to designers to reduce embodied carbon in building design, and how planning recommendations on materials, massing and treatment of sites may affect embodied carbon.

For everyone working in the construction of buildings, the leap of knowledge and skill required to be able to fulfil this goal is still relatively large, but far from insurmountable.

Acoustics, Ventilation and Overheating Guide

It recommends an approach to acoustic assessments for new residential development that take due regard of the interdependence of provisions for acoustics, ventilation, and overheating. Application of the AVO Guide is intended to demonstrate good acoustic design as described in the ProPG: Planning & Noise, May 2017 when considering internal noise level guidelines.

Net Zero 1-Pager

2019 has been a watershed year. The climate emergency is now acknowledged and there is widespread support for an acceleration of the transition to Net Zero Carbon.

By 2030 all new buildings must operate at net zero to meet our climate change targets. This means that by 2025 all new buildings will need to be designed to meet these targets. We therefore have five years to do it progressively so that it becomes the norm in 2025. We should start now.

Industry consensus has been established on the key features of Net Zero Operational Carbon buildings. This new 1-page summary was launched by the London Energy Transformation Initiative (LETI) on 16.12.19 at Feilden Clegg Bradley Studios.  

It is the result of a very successful industry consultation with more than 330 responses and has been developed in collaboration with the UK Green Building Council (UKGBC) and the Better Building Partnership (BBP). It is also supported by the Good Homes Alliance (GHA), the Royal Institute of British Architects (RIBA) and the Chartered Institution of Building Services Engineers (CIBSE).
