Self sustaining homes

This publication is CPI’s analysis of Green, Affordable Housing Finance, an innovative climate finance instrument endorsed by The Global Innovation Lab for Climate Finance  (the Lab). CPI serves as the Lab’s Secretariat. Each instrument endorsed by the Lab is rigorously analyzed by our research teams. High-level findings of this research are published on each instrument, so that others may leverage this analysis to further their own climate finance innovation.


Demographic trends in Africa and Asia necessitate massive investment in affordable homes for the hundreds of millions people living in sub-standard housing. As buildings account for 37% of energy-related GHG emissions globally, it is imperative that this housing gap is met with a housing stock that is more sustainable than that which exists today.

Well-built, energy- and water-efficient housing can help marginalized communities adapt to climate-linked disasters, including extreme heat, flooding, drought, and tropical cyclones, while secure tenure and low energy bills provide a route to long-term financial independence and resilience.

However, a chronic lack of finance for developers and prospective homeowners constrains the construction of climate-smart affordable homes at the scale required to address these challenges.

Green Affordable Housing Finance deploys construction and mortgage loan guarantees alongside targeted enabling interventions to foster a locally driven and self-sustaining affordable housing finance ecosystem


Green Affordable Housing Finance’s core innovation lies in its capacity to incentivize local lenders to finance both construction of affordable green homes and the purchase of those homes by households with low and informal incomes. It does this through the coordinated deployment of construction and mortgage loan guarantees to support the supply and demand side of the affordable housing sector. In doing so, the instrument aims to build the foundation for an eventual self-sustaining housing finance ecosystem for climate-smart, affordable homes.


Reall will pilot the instrument in Kenya before expanding throughout Sub-Saharan Africa and South Asia. All homes supported by the instrument will meet industry standard green certification requirements and target populations unserved by conventional housing finance solutions. Over time, the instrument will target increasingly innovative and high-impact home designs as it approaches net zero construction. During the five-year pilot phase, the Guarantee Facility is expected to mobilize USD 37 million in lending activity for green, affordable homes. Upon scale-up, the guarantee facility is expected to support over USD 400 million in local private loans over 15 years.


The instrument will capitalize an Enabling Environment Facility (EEF) and a Guarantee Facility to provide coordinated support for green affordable homes across the housing finance value chain.

To catalyze new housing supply, the EEF will deploy targeted construction finance and technical assistance to allow high-impact local developers to establish an operating track record and attain bankability. Meanwhile, the Guarantee Facility will de-risk construction loans issued by local lenders to further scale the development of certified green affordable homes.

In parallel, the EEF will support local lenders in adopting alternative credit assessment to underwrite borrowers with low and informal incomes. The Guarantee Facility will then de-risk mortgages for those borrowers to expand credit access and offtake for developers of green affordable homes.

The deployment of technical assistance and construction finance via the EEF alongside construction and mortgage guarantees via the Guarantee Facility provides a value chain approach to accelerating the development of a self-sustaining housing finance ecosystem.

Each review score is between 1-10. To get the overall score that you see, we add up all the review scores we’ve received and divide that total by the number of review scores we’ve received. In addition, guests can give separate ‘subscores’ in crucial areas, such as location, cleanliness, staff, comfort, facilities, value for money and free Wi-Fi. Note that guests submit their subscores and their overall scores independently, so there’s no direct link between them.

You can review an Accommodation that you booked through our Platform if you stayed there or if you arrived at the property but didn’t actually stay there. To edit a review you’ve already submitted, please contact our Customer Service team.

We have people and automated systems that specialise in detecting fake reviews submitted to our Platform. If we find any, we delete them and, if necessary, take action against whoever is responsible.

Anyone else who spots something suspicious can always report it to our Customer Service team, so our Fraud team can investigate.

Ideally, we would publish every review we receive, whether positive or negative. However, we won’t display any review that includes or refers to (among other things):

  • Politically sensitive comments
  • Promotional content
  • Illegal activities
  • Personal or sensitive information (e.g. emails, phone numbers or credit card info)
  • Swear words, sexual references, hate speech, discriminatory remarks, threats, or references to violence
  • Spam and fake content
  • Animal cruelty
  • Impersonation (e.g. if the writer is claiming to be someone else)
  • Any violation of our review guidelines.

To make sure reviews are relevant, we may only accept reviews that are submitted within 3 months of checking out, and we may stop showing reviews once they’re 36 months old – or if the Accommodation has a change of ownership.

An Accommodation may choose to reply to a review.

When you see multiple reviews, the most recent ones will be at the top, subject to a few other factors (what language a review is in, whether it’s just a rating or contains comments as well, etc.). If you like, you can sort and/or filter them (by time of year, review score, etc.).

We sometimes show external review scores from other well-known travel websites. We make it clear when we’ve done this.

Guidelines and standards for Reviews

These guidelines and standards aim to keep the content on relevant and family-friendly without limiting expression of strong opinions. They are also applicable regardless of the sentiment of the comment.

Contributions should be travel related. The most helpful contributions are detailed and help others make better decisions. Please don’t include personal, political, ethical, or religious commentary. Promotional content will be removed and issues concerning’s services should be routed to our Customer Service or Accommodation Service teams.

Contributions should be appropriate for a global audience. Please avoid using profanity or attempts to approximate profanity with creative spelling, in any language. Comments and media that include ‘hate speech’, discriminatory remarks, threats, sexually explicit remarks, violence, and the promotion of illegal activity are not permitted.

All content should be genuine and unique to the guest. Reviews are most valuable when they are original and unbiased. Your contribution should be yours. property partners should not post on behalf of guests or offer incentives in exchange for reviews. Attempts to bring down the rating of a competitor by submitting a negative review will not be tolerated.

Respect the privacy of others. will make an effort to obscure email addresses, telephone numbers, website addresses, social media accounts, and similar details.

The opinions expressed in contributions are those of customers and properties and not of does not accept responsibility or liability for any reviews or responses. is a distributor (without any obligation to verify) and not a publisher of these comments and responses.

By default, reviews are sorted based on the date of the review and on additional criteria to display the most relevant reviews, including but not limited to: your language, reviews with text, and non-anonymous reviews. Additional sorting options may be available (by type of traveller, by score, etc.).

The house is a building that serves as a residence or occupancy and means of fostering the family. Some people have not realized that the participation of environmental care in overcoming global warming and climate change can start from their respective homes, which is by implementing eco-friendly house. This is evidenced by a large number of people who use full land without leaving green spaces, excessive use of electrical energy, excessive and uncontrolled water use, and so on. Energy conservation is the efficient and rational use of energy without reducing the vital energy usage. Green Ship Homes of Green Building Council Indonesia (GBCI) establishes several criteria in relation to the assessment of green buildings on conservation and energy efficiency. These requirements are electricity metering, passive design analysis, sub-metering, artificial lighting, thermal condition, heat reduction, home appliance energy-saving home appliances and renewable energy source. The purpose of this research was to produce learning media in the form of 2D drawings, 3D images, booklets, and homesteads that apply the principles of conservation and energy efficiency. The learning media was designed based on the conservation and energy efficiency principles of Green Ship Homes from GBCI. This development research was initiated by observation, literature review, design preparation, media creation and media validation. The results of this study showed that media has been validated by experts as excellent in use as a tool in environmental education in building vocational engineering education. Based on the results of media field trials, it is included in the category of very feasible. It shows the use of conservation media and energy efficiency at the university level is very necessary in the effort of environmental conservation through the educational sphere.
