The aim of the CROWDFUNDING campaign

“Leaf-Boa Go Green Lisboa”

is to raise awareness among travellers as to the choice of lodgings with green credentials and help tourist accommodation owners to improve their ecological and environmental performance


lisbon-portugal TNTMAGAZINE

Our focus in this campaign will be on reaching 6,100 lodgings in Lisbon



to provide hotel and lodging owners with a practical guide on the main areas of interest for a hotel that is environmentally friendly


air conditioning

electrical equipment

water consumption

air quality inside the building

products and services relating to personal hygiene

waste management

training of staff 


interaction with stakeholders and

ecological supplies and acquisition

At an average of 30 contacts per team member/per day with 4 people making 2,400 contacts over 3 months, this gives us

7,200 contacts

This figure is more than enough for one contact per hotel or other lodging, and means that there is flexibility in the workload taken on by members of the team.

Once we reach 6,100€ through crowd funding (the equivalent of 1€ = 1 lodging) we can start on the initiative.

That’s all you have to do:


1€ = 1 lodging

Green Deal

Green DealThe new UK government policy for upgrading poor quality housing

Finance has been available since January 2013 in the UK for 45 energy saving measures for improving your property.

Loans are repaid through energy bills and are transferred with the property to new users – a novel concept in this country.

Homeowners repay the Green Deal charge on their monthly bill, even if the promised savings on their energy bills do not materialize, but the intention is that savings on energy bills will outweigh the cost of repayments.

This has been the Department of Energy and Climate Change’s policy since October 2012 and although interest rates are higher than average household loans, the aspiration is that the general public will join and help upgrade the quality of the country’s housing stock.

In terms of heating, ventilation and air conditioning, measures range from installation of equipment (boilers, gas recovery devices, ground and air source heat pumps) to complete systems (heat recovery, heating controls, mechanical ventilation and under-floor heating).

With building fabric, insulation and draught proofing are paramount (cavity walls, flat roofs, external and internal walling, floors and lofts) with the emphasis also on heating systems (cylinders and pipework).

With lighting, fittings and controls are considered; with water heating, innovative hot water systems and water efficient taps and showers are contemplated; with fenestration, energy efficient glazing and doors have been included.

Further measures have been confirmed to include roof lights, lamps and luminaires, radiant heating, solar blinds, shutters and shading devices as well as solar collectors, chillers, fans and pumps.

Cooperative relationships are built upon  mutual interest, the aim being to support each other as well as create an interactive environment without restraints. A balance between a cooperative and a competitive interaction amongst businesses in the same sector is however a big dilemma and what needs to be ensured is that neither one of the two ways of conduct can harm the other or its strategies. It remains however the recipe for success and market sustainability when balanced and implemented in an ethical context.

Developing countries need more and more an enabling environment in order to create economic growth within the private sector. Since the confirmation of two of the biggest world events in Brazil, the FIFA World Cup 2014™ and the Olympic Games 2016™, the country has been targeted by large, international companies of all sectors in search of opportunities in this promising market.

Local business owners have since then experienced a whole new competitive environment and guided by SEBRAE[1], a private business funded by the local government and focused on the development of small businesses, have created cooperation committees based on a mutually beneficial exchange. These relationships are built on a distribution of activities and resources among actors embedded in the same business network.

According to SEBRAE there are 778 active business cooperation committees in Brazil (2011) and the results vary by segment.

Using the tourism industry as an example, small businesses get together and share valuable information regarding their purchases, suppliers and prices. Power of negotiation can be very limited when a small business stands by itself, but when 30 establishments get together to purchase linen, toilet paper or whatever they may need, they can achieve a much better result, increase profits and provide economic growth. This format is used to purchase an infinite number of products and services that are vital to their businesses and enhance competitiveness.

In some committees, even marketing strategies and efforts as well as environmental solutions are shared for the benefit of a destination, especially in the tourism segment. Business sustainability is about an integrated strategy that allows financial growth, community development and environmental  awareness.

“If we do not hang together, we will all hang separately”, Benjamin Franklin (1706-1790), American statesman, scientist and philosopher.

National Green Week


National Green Week kicks off in schools in the States this week (4-7 February). Projects and activities will go on up to Earth Month in April.

Many hotels work with local schools or part of their proceeds go directly to them.
If you are such a hotel, you might like to combine efforts by further helping the environment with the Green Education Foundation (GEF), whose mission is to create a sustainable future through education.
The foundation provides information for schools to develop projects to improve energy efficiency through simple measures geared to change students’ behaviour.
Their view is that through taking small steps towards educating students to be more pro-active on green subjects, the overall impact on society will be greater.
The U.S. Department of Energy estimates that schools could save up to 50% of their energy costs by following simple measures and the GEF chose for 2013 six types of “green challenge” which does just that.



The “Green Energy Challenge” looks at reduction of paper waste (considered to be approximately 40% of U.S. waste): how every ton of recycled paper cuts down oil consumption; how energy saved from recycling aluminium will be set off against operating electrical appliances; how glass can be infinitely recycled; and how one should minimize the use of plastic.
The “Waste Reduction Challenge” focus on how recycling reduces greenhouse gas emissions and decreases the need for disposal with reduction of landfill or incineration and decrease in CO2 produced. It also shows ton for ton how recycling is taken to be the best option for solid waste management.
The “Green Thumb Challenge” encourages students to connect to the garden and the GEF provides gardening tools and resources for schools as well as curriculum and activities to be used in the classroom.
The “I Ride Green Challenge” encourages students and staff to “Think green when they travel” – everything has been contemplated, from riding a bike to carpooling.
The “Green Building Program” focuses on how design considerations can affect ways in which buildings react to their surroundings and how changes in construction can help conserve natural resources.
Finally, the “Sustainable Water Challenge” calls upon all participants to save water at home and school to preserve our planet’s valuable resource.

Hot climates depend heavily on air conditioning systems, and it is well known that 70% of the power used at peak times can be traced back to them.

So anything which can be done to alter this figure can be seen as a means for cities to become more sustainable. One way is to focus on the source of this power; another is to find a controlled way of distributing it: thinking globally rather than individually.

The Pearl in Qatar is an island which was designed with this process in mind back in 2006. It has saved 40% to 60% of the required power over conventional systems. Less power in this case means fewer harmful emissions, less refrigerant leakage and also less noise pollution.

In order to accomplish this, one has to start by raising awareness of the potential available from optimising energy efficiency and conserving natural resources. In effect, it is back to the 3 E’s: environment – energy – economy.

And the end user should be the first to be considered, with everyone else involved being tracked back to the stakeholders. Without the end user engaged, no true partnership can be fostered with the community.

We are looking here at district cooling rather than individual units to cool each home. An expensive outlay at the outset of the project but well worth it when balanced against to benefits it brings to the end users.

Think of it: a utility service which provides chilled water through a centralised cooling plant to a pipe network, feeding residential, industrial and commercial buildings, increasing energy efficiency, reducing emissions, GHG[1] and ozone-destroying refrigerants.

In terms of cost benefits, the public-private partnership in Pearl Island was able to cut capital costs on equipment and also reduce control panels. The internal power distribution was minimised, the annual maintenance concentrated on one plant rather than several outlets and power consumption in individual buildings greatly reduced.

For the whole process to run smoothly, planning has to the foremost target from the outset: to reach a correct design process, choose adequate equipment and use the right resources.

In aesthetic terms, no more bulky A/C units on roofs, hanging from walls, cluttering balconies or clogging up yards. No noise and no vibration on building structures. No worries about operating and maintaining equipment.

All the end user has to do is to enjoy the added comfort, clean the unit filter when needed, pocket the savings and have the satisfaction of having contributed to reducing their impact on the environment.
