Crown Developments - Sustainability

Sustainability is relevant to development projects

A definition of development sustainability is "the continuation of benefits after major assistance from the donor has been completed" (Australian Agency for International Development 2000).

Ensuring that development projects are sustainable can reduce the likelihood of them collapsing after they have just been finished; it also reduces the financial cost of development projects and the subsequent social problems, such as dependence of the stakeholders on external donors and their resources. All development assistance, apart from temporary emergency and humanitarian relief efforts, should be designed and implemented with the aim of achieving sustainable benefits. There are ten key factors that influence development sustainability.

Participation and ownership.

Encourage the stakeholders (men and women) to genuinely participate in design and implementation. Build on their initiatives and demands. Involve them in monitoring the project and periodically evaluating its results.

Capacity building and training.

Training stakeholders to take over should begin from the start of any project and continue throughout. The right approach should both motivate and transfer skills to people.

Government policies.

Development projects should be aligned with local government policies.

Financial.

In some countries and sectors, financial sustainability is difficult in the medium term. Training in local fundraising is a possibility, as is identifying links with the private sector, charging for use, and encouraging policy reforms.

Management and organisation.

Activities that integrate with or add to local structures may have better prospects for sustainability than those which establish new or parallel structures

Social, gender and culture.

The introduction of new ideas, technologies and skills requires an understanding of local decision-making systems, gender divisions and cultural preferences.

Technology.

All outside equipment must be selected with careful consideration given to the local finance available for maintenance and replacement. Cultural acceptability and the local capacity to maintain equipment and buy spare parts are vital

Environment.

Poor rural communities that depend on natural resources should be involved in identifying and managing environmental risks. Urban communities should identify and manage waste disposal and pollution risks

External political and economic factors.

In a weak economy, projects should not be too complicated, ambitious or expensive.

Realistic duration.

A short-term project may be inadequate for solving entrenched problems in a sustainable way, particularly when behavioural and institutional changes are intended. A long-term project may, on the other hand, promote dependence.

Sustainable and Renewable Energy

  • Biomass Boilers – wood pellets, wood chips and locally supplied sunflower oil seed waste can be used to fuel the boilers.

Wood pellets and chips are Carbon Neutral due to the following facts:

  • They are from a sustainable source and a living organism. The planting of new trees will absorb the CO2 emissions produced from burning the wood pellets.
  • Went burnt, the carbon dioxide that is released into the atmosphere is only the same as the CO2 that would be released when it died and decomposed.
  • The carbon dioxide released when wood is burnt is the same as that absorbed by the tree when it was growing.

Heat Pumps (Air, Water or Ground Source)

  • Air Source – air is heated by the sun even in the coldest of conditions and reduces the amount of energy needed to raise the temperature of the air to a comfortable level and lessons the demand on the heat pump.
  • Water Source – ground water is a good source of solar energy. Even on the coldest days in winter, temperatures of +7 OC to 12 OC can be achieved, again aiding the heat pump meet its output.
  • Ground Source – at a depth of just 1.2 to 1.5m, the ground remains warm enough to enable an economical heat pump operation and can be used to increase or reduce the heat of the fluids passing through it and therefore reducing the demand to artificially increase or reduce the temperature at ground level.

Solar Power and Heat (Photovolaitics)

Using the sun’s natural emissions to harvest energy for light power and water heating. Even in dull days where the sun doesn’t appear to be out, solar emissions can still be harvested.

Wind Turbines

Wind Turbines – in open areas these can harvest the natural phenomenon that is wind and convert the same into energy.

Thermal Mass

Thermal Mass – Using dense material will act as storage of the excess heat from solar gain during the day and allow this to dispel during the evening and overnight. In colder days the mass will absorb the cold air thus increasing the ambient temperature. Concrete and masonry are prime examples of this.

Our social responsibility does not end with the environment.

We consider all aspects when designing our developments and accessibility by those less able bodied is a criteria we adopt. As with the UK building market, the Disability Discrimination Act dictates that everyone should have access to services being provided and we at Crown Developments cherish this view and our schemes are designed to meet the needs of those who require a little bit of special consideration when navigating around developments and complexes.

That is why we employ British designers to add that extra value into our schemes to cater for everyone and to allow no one to be discriminated against when purchasing one of our prestige apartments or villas.

Construction Environmental

and Social Responsibility Statement

Global warming and climate change have been at the forefront of the news recently with damage to the environment and ways to reverse the effect of CO2 emissions being key areas of discussion from political standing to the protection of the next generations to come.

t

We at Crown Developments identify the need to play a significant role in the protection of the environment and incorporate environmentally friendly and sustainable practices into our developments from the outset.

Created within our scenic and historically located development schemes in Bulgaria we have identified the following key issues to help the effect of global warming and protect the environment;

Local resourcing of materials and labour

  • Using locally produced materials and supplies not only helps the local community and economy, but reduces the transportation distances and thus reduces CO2 emissions from the vehicles. Employing local labour again reduces the need for excess travelling and the increased carbon emissions associated with this.
  • Employing local labour again reduces the need for excess travelling and the increased carbon emissions associated with this.

Green and Brown roofs

  • The benefits are not only visually pleasing but they help protect the environment from the new construction and replenish the “green” element back into the area.
  • It is a well know fact that construction developments take away the green areas and reduce the countryside and associated nature. Including green roofs allows the local wildlife to remain in the habitat similar to that before the development.
  • Rainwater run-off from traditional roofs is sent into the local sewer system and is lost into rivers and does not replenish local water sources. Green roofs encourage the rainwater to remain within the plants on the roof where it helps irrigate the green foliage and is then allowed to evaporate into the air where it will be distributed as rain and allowed back into the local water courses. It also reduces the volume of rainwater that pours onto hard surfaces, lessoning the risk of flash flooding.
  • Adding the green elements to the roof will act as an insulation barrier to help retain heat within the building in the winter and reduce heat build up in the summer.
  • The green element also helps maintain the integrity of the roof finish extending the roof life.
  • The air quality will be increased around the building due to the plants absorption of CO2.

Grey water and rainwater harvesting

  • Using the waste water from washing machines, showers, baths and basins within the building will mitigate the need for disposing of the same and help maintain local supplies. The waste water will be collected for use in toilet flushing and use in the garden. This will reduce the demand on the local fresh water supply to the buildings.
  • Using rainwater harvesting allows the water to be collected for use within the garden and minimises the amount of rainwater lost in sewers.

Recycling and recycled materials

  • It is a well known fact that using recycled materials will reduce the impact on the environment, reducing the manufacturing process, mining raw materials and waste disposal.

ecology

Sustainable Drainage Systems (SUDS)

  • As with the result of the development, surrounding roads and car parking etc., there is a tendency for the rain fall to be directed via gullies into the local sewer network and sent to the rivers, thus not replenishing the local water courses. With replacing green areas with new developments we need to look at redirecting this rainfall back into the local environment and with the use of SUDS this can help.
  • The drainage will collect the rainfall as usual but will encourage natural groundwater recharge and mimic nature as closely as possible thus sustaining the local environment.
