Conceptual Visualisation

The Building will use a Water Reclamation System to retain water from rainfall which lands on the srea of the roof of the building. This water will be harvested via gutter drainage leading to a filtration system to be cleaned and filter out any unwated content. This clean water will then proceed through the system into the tank, which size has been calculated to minimise the risk of any overflow. The water stored in the tank will be used as Grey water, meaning it will be used for purposes such as toilet flushing and not for ingestion.

Rainfall Harvesting Forumla

Roof area x annual rainfall x run off coefficient x filter coefficient

1,026m2 * 1,407mm * 0.8 * 0.9 = 1,039,379 Litres per annum

1,039,379 Litres * 0.05 = 51,968 Litre Tank Size Miinimum

This formula helps determine what size tank to pair with the system and for it to be the neccessary size to collect the amount of rainfall expected.

The heating strategy for this building will be to use a Ground Source Heat Pump, paired with an underfloor heating system, The use of coiled heat recovery pipes allows for the neccessary length of the pipes to be installed in a much smalled area yet yeilding the same results.

The use of a underfloor heating system will allow the whole building to be heated and benefits from this as it is a single floor building.

The building ventilates naturally with a vary of opening windows in the main spaces to allow fresh air to pass trhough the building from river. The natural ventilation will also help carry with warm air around various areas of the building creating a constant and stable temperature within the building.

Exhaused air will be allowed to escape via the upstand glazed windows in the main pasage of the building. These windows will be controlled automatically when the building reaches a certain hight temperature or on a timed basis.

The system will be powered a summer and winter energy strategy. In the summer the use of Photovoltaic glass will be used on the east facade of the building. Exposed to the most sunlight it will export the solar power into various areas of the building the heat pump beimg one of them. In the winter where the succsess of solar power is less prominent, the use of a Hydro Generator located in the river will provide power throughout the colder months where the river Leven’s levels are at its highest and most rapid.
