Pearns Point, Antigua Sustainable Design

Pearns point sustainable house

The environmentally aware design maximises every Site’s attributes, harnessing their position and utilising the available natural resources. The Caribbean is blessed with the finest sunshine, wind, sea and seasonal rainwater, so a good starting point.



Technology now allows us to study and understand the Site and what natural elements are available in the specific position, often a comfortable elevation sits just 2 metres above a still dry hollow.

Initial studies will completely understand not only the best access, views, sunrise, sunset, but also prevailing winds and elevation differences to maximise every sites possibilities a digital feng-shui for every site.



12 hours of sunshine throughout the year is captured with PV Panels, these can be stand alone or integrated into the design and disguised as shingles, tiles or glass.

This energy is stored in batteries that can then provide the energy later in the day for lighting and air conditioning use.



Solar path analysis and CAD design paces allow us to study the sun at every pint of the day and year, so that we can ensure the house provides shade to every window and generous outdoor living and dining spaces.



Passive cooling is designed into the plans, harnessing the wind and channeling it to provide comfortable breeze backed up by large battery driven ceiling fans.

Deep water bore holes into the sea bed provide free chilled water around the house from solar driven pumps to water source heat pumps for AC comfort cooling.

Waste heat from the heat pumps is reused for water heating and the swimming pool topped up with solar.

Humidity can be removed by a dessicant wheel driven from the batteries.


Wind Power

With the trade winds blowing through the site free energy is available, however rather than noisy huge win turbines were using micro-generation wind turbines embedded into the building to negate noise and to maximise venture air acceleration this is sent to the central batteries.



Rainwater is collected and harvested, grey water is reused and finally after being treated by coconut shells irrigates the planting.



The house is fully active and entirely controlled by a central computer giving full control of every system and monitoring the house for optimum ventilation and environmental control.

Actuated windows and roof lights encourage wind flow, and cooling is delivered to over heating areas and external blinds are activated at low level sun conditions.



Low energy LE~D lugging is ned thought and PIR controlled, a ‘Dark Skies’ policy is embrace to minimise external lighting and to allow the night sky to be enjoyed.
