1 EXECUTIVE SUMMARY
1.1 Overview
1.1.1 Right of Light Consulting has been commissioned by Peace Pennels LLP to
undertake a daylight and sunlight study of the proposed development at 7 Hucclecote
Road, Gloucester, Gloucestershire GL3 3TQ.
1.1.2 The aim of the study is to assess the impact of the development on the light
receivable by the neighbouring residential properties at 1 & 11 Hucclecote Road, 10
to 32 Insley Gardens and 10 to 20 Ellesmere Close. The study is based on the
various numerical tests laid down in the Building Research Establishment (BRE)
guide ‘Site Layout Planning for Daylight and Sunlight: a guide to good practice’ by P J
Littlefair 2011.
1.1.3 The window key in Appendix 1 identifies the windows analysed in this study.
Appendix 2 gives the numerical results of the various daylight and sunlight tests. The
results confirm that all neighbouring windows pass the BRE diffuse daylight and direct
sunlight tests. The development also satisfies the BRE overshadowing to gardens
and open spaces requirements.
1.1.4 In summary, the proposed development will have a low impact on the light receivable
by its neighbouring properties. Right of Light Consulting confirms that the
development design satisfies all of the requirements set out in the BRE guide ‘Site
Layout Planning for Daylight and Sunlight’.

3 METHODOLOGY OF THE STUDY
3.1 BRE Guide : Site Layout Planning for Daylight and Sunlight
3.1.1 The study is based on the various numerical tests laid down in the Building Research
Establishment (BRE) guide ‘Site Layout Planning for Daylight and Sunlight: a guide to
good practice’ by P J Littlefair 2011. In general, the BRE tests are based on the
requirements of the British Standard, BS 8206 Part 2.
3.1.2 The standards set out in the BRE guide are intended to be used flexibly. The
following statement is quoted directly from the BRE guide:
3.1.3 “The guide is intended for building designers and their clients, consultants and
planning officials. The advice given here is not mandatory and the guide should not
be seen as an instrument of planning policy; its aim is to help rather than constrain
the designer. Although it gives numerical guidelines, these should be interpreted
flexibly, since natural lighting is only one of many factors in site layout design.”
3.2 Daylight to Windows
3.2.1 Diffuse daylight is the light received from the sun which has been diffused through the
sky. Even on a cloudy day, when the sun is not visible, a room will continue to be lit
with light from the sky. This is diffuse daylight.
Diffuse daylight calculations should be undertaken to all rooms where daylight is
required, including living rooms, kitchens and bedrooms. Usually, if a kitchen is less
than 13m2, it is considered to be a non-habitable room and the daylight tests need not
be applied. The BRE guide states that windows to bathrooms, toilets, storerooms,
circulation areas and garages need not be analysed.
3.2.2 The BRE guide contains two tests which measure diffuse daylight:
3.2.3 Test 1 Vertical Sky Component
The percentage of the sky visible from the centre of a window is known as the
Vertical Sky Component. Diffuse daylight may be adversely affected if after a
development the Vertical Sky Component is both less than 27% and less than 0.8
times its former value.
DAYLIGHT AND SUNLIGHT STUDY7 Hucclecote Road, Gloucester, Gloucestershire GL3 3TQ Page 5
3.2.4 Test 2 Daylight Distribution
The BRE guide states that where room layouts are known, the impact on the
daylighting distribution can be found by plotting the ‘no sky line’ in each of the main
rooms. The no sky line is a line which separates areas of the working plane that do
and do not have a direct view of the sky. Daylight may be adversely affected if, after
the development, the area of the working plane in a room which can receive direct
skylight is reduced to less than 0.8 times its former value.
3.3 Sunlight availability to Windows
3.3.1 The BRE sunlight tests should be applied to all main living rooms and conservatories
which have a window which faces within 90 degrees of due south. The guide states
that kitchens and bedrooms are less important, although care should be taken not to
block too much sunlight.
3.3.2 The BRE guide states that sunlight availability may be adversely affected if the centre
of the window:
x receives less than 25% of annual probable sunlight hours, or less than 5% of
annual probable sunlight hours between 21 September and 21 March and
x receives less than 0.8 times its former sunlight hours during either period and
x has a reduction in sunlight received over the whole year greater than 4% of
annual probable sunlight hours.
3.4 Overshadowing to Gardens and Open Spaces
3.4.1 The availability of sunlight should be checked for all open spaces where sunlight is
required. This would normally include:
� Gardens, usually the main back garden of a house� Parks and playing fields� Children’s playgrounds� Outdoor swimming pools and paddling pools� Sitting out areas, such as those between non-domestic buildings and in public
squares� Focal points for views such as a group of monuments or fountains.
DAYLIGHT AND SUNLIGHT STUDY7 Hucclecote Road, Gloucester, Gloucestershire GL3 3TQ Page 6
3.4.2 The BRE guide recommends that at least 50% of the area of each amenity space
listed above should receive at least two hours of sunlight on 21 March. If as a result
of new development an existing garden or amenity area does not meet the above,
and the area which can receive two hours of sunlight on 21 March is less than 0.8
times its former value, then the loss of light is likely to be noticeable.

4 RESULTS OF THE STUDY
4.1 Windows & Amenity Areas Considered
4.1.1 Appendix 1 provides a plan and photographs to indicate the positions of the windows
and gardens analysed in this study.
4.2 Numerical Results
4.2.1 Appendix 2 lists the detailed numerical daylight and sunlight test results. The results
are interpreted below.
4.3 Daylight to Windows
4.3.1 All windows pass the Vertical Sky Component test – before/after ratios of 0.94 and
above (against the BRE recommendation of 0.8). The proposed development
therefore satisfies the BRE daylight requirements.
4.4 Sunlight to Windows
4.4.1 All windows which face within 90 degrees of due south have been tested for direct
sunlight. All windows pass both the total annual sunlight hours test and the winter
sunlight hours test (annual probable sunlight hours between 21 September and 21
March). The proposed development therefore satisfies the BRE direct sunlight to
windows requirements.
4.5 Overshadowing to Gardens and Open Spaces
4.5.1 The results of the overshadowing test show that sunlight availability after the
development will be no less than 0.9 times the former value. This is better than the
BRE minimum requirement which permits sunlight to be reduced by up to 0.8 times.
The proposed development therefore passes the BRE overshadowing to gardens and
open spaces test.
4.6 Conclusion
4.6.1 The proposed development will have a low impact on the light receivable by its
neighbouring properties. Right of Light Consulting confirms that the development
design satisfies all of the requirements set out in the BRE guide ‘Site Layout Planning
for Daylight and Sunlight’.

“Surveying Safely”.
5.1.3 We have used our best endeavours to ensure all relevant windows within the
