Building a green house
According to international statistics, construction uses up more than 30% of the world’s resources, the building industry consumes 12% of fresh water in OECD countries and property development accounts for up to 40% of total energy consumption. As a result of this environmental impact, an international challenge has now been set for the property industry to consider how buildings can be made carbon neutral by 2020. There are already a number of projects in Thailand working to achieve this.
Below are some of the most effective approaches to eco-friendly building.

Passive designs
This refers to the use of simple design techniques that assist in controlling the ventilation and average temperatures within a building without the use of any mechanical systems. On Koh Samui, the Aqualina project by Exclusive Developments utilises passive cooling techniques and also features a series of planter beds on villa roofs that absorb heat, thus helping keep the building cool. In addition, external retaining walls contain compacted soil to insulate the building and keep its ambient temperature cooler than conventional structures.

Alternative energy
On-site energy generation from renewable sources such as the sun, the wind, the tide, the waves or even the crops that we grow, can take two forms: building-integrated renewable energy generation or stand-alone generation. Integrated ideas include solar powered hot water systems, which can be mounted on the north-facing roof. Meanwhile, with access to the right kind of wind, there is also the potential to build a medium scale wind turbine that feeds the buildings directly adjacent to it with electricity via its own power cable.

Water saving
Water is also a major consideration when building, both during the construction process and once the development is occupied. Ocean’s Edge Condominium project in Pattaya features purified drinking water, pumped from two on-site wells to every faucet in the development. In addition, the buildings include black and grey water storage, with treatment and recycling, as well as rainwater collection for use on the gardens. The construction itself also features ‘superblock’ a modern, aerated, lightweight brick and UPVC exterior doors and windows with three layers of glass to maintain internal temperatures.
Here on Phuket at Mai Khao Beach, the West Sands development is setting a similar example with green building techniques that include energy efficient hydrothermic air conditioning and hot water systems, water conservation practices, biodegradable refuse plants, solar energy, double-glazing, and superior insulation. Barry King is Director of Sales & Marketing for Central and City Developments, the company behind West Sands. He says that by choosing an outstanding natural location for the project, the idea was to offer an unrivaled lifestyle to residents and guests while at the same time striving to create the smallest environmental footprint possible.
