Business Models for Renewable Energy in the Built Environment

RE-BIZZ publication

Business Models for Renewable Energy in the Built Environment provides insight to policy makers and market actors as to the ways that new and innovative business models (and/or policy measures) can stimulate the deployment of renewable energy technologies (RET) and energy efficiency (EE) measures in this field.

This project was initiated and funded by the IEA Implementing Agreement for Renewable Energy Technology Deployment (IEA-RETD). It analyses ten business models in three categories, covering different types of energy service companies (ESCO’s).


  • developing properties certified with a ‘green’ building label
  • building owners profiting from rent increases after EE measures
  • property Assessed Clean Energy (PACE) financing
  • on-bill financing
  • leasing of RET equipment.

Coverage extends to the organisational and financial structure of the models and the existing market and policy context, plus analysis of Strengths, Weaknesses, Opportunities and Threats (SWOT).

The book concludes with recommendations for policy makers and other market actors on how to encourage and accelerate built environment renewable energy technologies.

This book can be ordered via the publisher for GBP 49.99 (excl shipping costs, incl VAT). Or directly via IEA_RETD@ecofys.com for EUR 45 (excl shipping costs, incl VAT).


READy: Renewable Energy Action on Deployment

policies for accelerated deployment of renewable energy

Are you developing strategies for a future sustainable energy supply? Are you designing policies to deploy renewable energy technologies in your country? Are you looking for new tools and measures to make your policies more effective? Are you planning to make decisions on renewable energy investments in certain countries and are you checking their policy robustness?

Let the IEA-RETD guide you into successful, efficient and effective policies and decisions for accelerating deployment of renewable energy. Learn about the six policy actions that are essential ingredients for your policy portfolio:

The ACTION star:

  • Alliance building: Build alliances and reach agreements among policy makers and with relevant stakeholders including industry members, consumers, investors, and others
  • Communicating: Communicate knowledge about renewable energy resources, technologies and issues to create awareness on all levels, address concerns of stakeholders, and build up the needed work force
  • Target setting: Clarify the goals, set ambitious targets on all levels of government, and enact policies to achieve goals.
  • Integrating: Integrate renewables into policymaking and take advantage of synergies with energy efficiency
  • Optimizing: Optimize policy frameworks by building on own policies or other proven policy mechanisms and adapting them to specific circumstances
  • Neutralizing: Neutralize disadvantages in the marketplace, such as misconceptions of costs and the lack of a level playing field

This book shows why and how successful renewable energy strategies work. Many recent and actual examples of best cases and experiences in policies–based on literature and interviews–show how policies can best mobilize national and international renewable energy business and the financial institutions, while creating broad support. The book is an initiative of the IEA-RETD, an international agreement between nine countries to investigate and accelerate the deployment of renewable energy deployment.

Offshore Renewable Energy

Gouri Bhuyan, Former chair and Operating Agent of the IEA OES-IA, a Lead Author of the IPCC SRREN, Principal Advisor on Alternative Energy at Powertech Labs, Canada:
“One of the most comprehesive reports to appear on offshore renewable energy; discussing opportunity, the current technical and non-technical callenges, and the need for different overarching policy frameworks from one country to another [...] highly recommended to policy makers, students, teachers, the general public, and other stakeholders.”

Wave, tidal and offshore wind technologies have long held the promise of seemingly limitless energy supplies. In practice, while offshore wind is growing relatively rapidly, all three sectors have lagged behind expectations. This book, from the International Energy Authority Renewable Energy Technology Deployment implementing agreement (IEA-RETD), examines the reasons for this and suggests how barriers to deployment might be overcome.

Beginning with an assessment of the marine energy resource, it provides a detailed introduction to the main technologies currently being employed to harness wind, tidal and offshore wind power. It then examines the types of policies which are used to encourage deployment around the world, and progress towards meeting targets. The economics of offshore energy projects are discussed, along with risks that projects face and the types of finance which are available. A final section turns to barriers – both technical and non-technical (including environmental, health and safety, skill related, supply chain and more) – and in all cases suggests how to mitigate and remove these barriers.

Highly illustrated in full colour, this is an indispensable resource for anyone – whether in industry, policy or academia – looking to learn more about how deployment of offshore renewable energy technologies can be encouraged.

Renewable Energy for Residential Heating and Cooling

Professor Ralph Sims, Massey University, New Zealand:
“Solar, biomass and geothermal resources already provide heating and cooling for single and multi-family dwellings. This book provides clear guidelines for both national and local policy-makers wishing to tap the huge potential by encouraging further cost-effective deployment”
Kristin M. Seyboth, Senior Scientist, IPCC WG III Technical Support Unit, Germany: “Historically, finding sound, comprehensive information on policies supporting renewable heating and cooling has been a challenge. This book fills an important knowledge gap by clearly outlining best practices for a sector that is critical to increasing the share of renewables in the energy mix.”
Doug McClenahan, former Chairman of the IEA’s Solar Heating & Cooling Programme, Canada: “A wealth of information on best practices from real programmes. A must-read for those developing new programmes to encourage the increased deployment of renewables, particularly solar thermal.”

Heating and cooling represent significant energy loads around the world, with the associated high level of carbon emissions. Many countries have commitments in place to derive an increasing proportion of the energy they use for heating and cooling from renewable sources; some are seeing greater success than others in moving towards these targets.

This best practices handbook from the International Energy Agency’s Renewable Energy Technology Deployment (RETD) Implementing Agreement provides energy policymakers and professionals in the renewable energy industry with a practical, easy to use guide and toolkit to the most effective policy options for deploying renewable energy for heating and cooling in the residential sector.

The book opens with a comparative review of renewable energy for heating and cooling policies in a broad range of IEA member countries from in Europe, Asia and North America, then goes on to present the policy approaches of the individual countries and more detailed studies of specific programmes. The second part of the book presents readers with flowcharts which allow them to navigate directly to the best practices which are most relevant to their situation. Planning, design and implementation are all covered, each with examination of the possible barriers that may be faced and the most appropriate policy response used to date.
