Abstract

A weatherproof enclosure rising from an opening in a roof 'M' of a building comprises surfaces which include both solar collectors 'E', 'W', 'S' and glazed areas 'N', 'D' for providing energy and daylight. The solar collectors are capable of being orientated and inclined for optimum efficiency when installed on any roof, irrespective of the orientation or inclination of the roof. The glazed areas may be formed by glazed panels, such as rooflights. Preferably, the weatherproof enclosure comprises a dormer window 'I' and the solar collectors may be used for generating electricity or heating water. In use, the enclosure provides solar energy and increased daylight, as well as extra headroom within a roof space, such as an attic or loft, whilst maintaining current standards of insulation and weatherproofing.

Description

Universal Solar Collector and Roof Window (The Invention')
DESCRIPTION
Background
To reduce net fuel consumption and consequent carbon emissions buildings are increasingly being provided with solar collectors which generate electricity or heat water using solar energy,.
Where it is intended to add usable space by converting existing roof spaces there needs to be sufficient headroom and daylight. The resulting building works may be so devised as to reduce the net fuel consumption of the building by incorporating solar collectors.
Improvements of this sort comply with principles of sustainability by making better use of existing buildings rather than resorting to demolition and rebuilding.
In England and Wales planning regulations were amended in October 2008 to make loft conversions, among other house extensions, easier. Permission is no longer necessary where roofs to the rear of a dwelling are to be altered, within certain limits.
Heat loss through existing roofs is a principal factor aggravating the problem of carbon emissions. Most of the roofs now existing will still exist at dates for which international targets have been set for large reductions in such emissions. To improve the performance of roofs is a necessary part of any reduction strategy.
A Current Problem Solved Solar collectors in many cases take the form of rectangular panels closely mounted parallel to the surface of the roof of the building. In some cases solar collectors are integrated into the plane of a roof and combined with roof windows. Since their efficiency varies with their inclination and orientation many collectors operate at less than optimum efficiency where roof inclination and orientation is unfavourable. In cases of easterly and westerly orientation collectors will be operating at less than optimum efficiency. In the case of northerly orientation solar collectors would be totally inefficient, and their installation in such roofs pointless.
The Invention overcomes this problem, and operates on any roof at optimum efficiency.
The Invention consists of two parts: first, a lower part or hollow base with or without a glazed panel or panels in its sides, erected so as to stand up from an opening in the roof, and presenting at its top a horizontal aperture which on plan is either a square, a circle or a regular polygon, and secondly an upper part fitting closely on to the lower part and consisting of one or more solar collectors either with or without one or more glazed panels, the upper part being rotated in the horizontal plane so that when installed it is in the orientation that provides optimum efficiency of the solar collectors.
A Practical Application -The Invention as a Dormer Window Where a dwelling is to be improved by the addition of living accommodation in the loft space and a dormer window is proposed to provide daylight or headroom or both The Invention can take that form, i.e. that of a dormer window. The upper part of The Invention forms the roof of the dormer window, and is set on the lower part in the orientation that provides optimum efficiency for the solar collectors, which can therefore be obtained whatever the orientation of the existing main roof. The solar collectors are inclined for optimum efficiency whatever the slope of the existing main roof.
As a dormer window the upper part of The Invention is capable of prefabrication and mass production. The lower part is individually constructed so as to marry the upper part to an existing or proposed roof.
Such a practical application has the advantages here claimed in the case of very large numbers of existing dwellings. In the short term a large reduction could be achieved in carbon emissions attributable to the energy consumption of existing dwellings, whether from energy generated at power stations or fuel burnt in domestic installations, by applying The Invention on a large scale.
Drawings Sheet 112 shows, using the axonometric convention, how The Invention would be installed as a dormer window where the main roof slope has a southerly, northerly, easterly or westerly orientation (Figures 1 -4).
Sheet 2/2 shows how The Invention can be applied in the case of a loft conversion to a two-storey terrace house with a two-storey back wing and a garden to the north.
The rear elevation of the house (Figure 6) shows The Invention in the form of a dormer window inserted into the existing main roof, which inclines northward towards the garden.
Figure 5 and Figure 7 show how The invention relates to the rest of the house in section and plan.
Solar collectors forming part of The Invention, whether for generating electricity or heating water, are of weatherproof materials and construction and incorporate insulation to reduce heat loss from the building. The base forming the lower part of the invention is made of building materials, such as timber with lead coverings, in accordance with local building practice.
