Buildings as Power Stations

Buildings as Power Stations

Vision: ‘To functionalise the whole building envelope …. new build and existing.’

Generate . Store . Release.

Scale-up Technologies

• Generation:

• Photovoltaic, Solar-thermal

• Storage:

• Batteries, Thermal

• Release:

• Lighting, Heating

All delivered by the scale up printing of functional coatings

• To be installed by end of August 2014

• Programme of works for pilot line being developed to suit

Partners:1. Bathgate/Permaflor Office

Demonstrators – Heated Tile (3 demos)

SBRI Heritage bid with Stride Treglown ArchitectsPermeable Insulation and Power (PIP) system

• Supplying 4 sheets with conductive coating applied for use in the demonstration project

• Monitoring of the system to assess the efficacy

• Project will inform future design and research

Solar Air Collector and Solar Store on an industrial shed

BIPV on roofThin film photovoltaics are factory applied to the roof sheeting, offering a robust and aesthetically pleasing solution.

TSC on wallsTranspired solar collector on south facing walls draws warm air into the building to provide space heating either directly or to be stored for later use.

StorageWarm air from the TSC is stored in a tank supplying the heating system. Electricity generated by the photovoltaics is stored in batteries.

Water purificationRainfall on the roof passes over a photoactive TiO2 coated metal roof sheeting, which removes organic matter. This is collected, passed through a filter and stored for use in the house.

ReleaseEnergy generated by the building envelope is released throughout the house via heating, lighting, electrical equipment and water use.

BUILDINGS AS POWER STATIONS

ACTIVE ENERGY GENERATOR NOT PASSIVE CONSUMERS

The main objective is to create a TOOL which allows to:

Integrate Supply Storage and Demand into the same building.

Model a Residential Scale Hybrid systems.

‘BIRE’ SUPPLY

DEMAND LOADS

ELECTRICAL STORAGE
