1.0 Executive Summary
We have undertaken a daylight and sunlight assessment of the Proposed scheme prepared by Make Architects (received 19 June 2017) for the Site at 20 Ropemaker Street, 101-117 Finsbury Pavement and 10-12 Finsbury Street, Islington.
It is important to reiterate that alterations in daylight and sunlight to adjoining properties are often inevitable when undertaking any meaningful development, especially in an urban environment such as this. Therefore, the BRE Guide is meant to be interpreted flexibly because natural lighting is only one of many factors in site layout design. The BRE guidelines suggest that different criteria may be used based upon the requirements for natural lighting in an area viewed against other constraints.
GIA have identified 15 properties surrounding the Site which could potentially experience alterations in light as a result of the proposed redevelopment of 20 Ropemaker Street, 101-117 Finsbury Pavement and 10-12 Finsbury Street. Of those 15, we have identified that one property, The Heron at 5 Moor Lane to the west of the Site, contains residential accommodation and therefore has been assessed for daylight and sunlight in accordance with the BRE guidance and for the purposes of town planning. All other properties we have identified as being commercial in use and therefore not necessary to assess for daylight and sunlight.
Our daylight and sunlight assessment for The Heron demonstrates all windows will meet the BRE guidance for VSC with the proposal in place, with just a few minor transgressions from the BRE guidance with reference to the daylight distribution within six of the rooms, and minor impacts to sunlight to three windows.

2.0 Instructions
GIA have been instructed to undertake detailed technical assessments to understand the potential daylight (VSC and NSL) and sunlight (APSH) changes that the proposed Make Architects scheme received 19 June for the 20 Ropemaker Street, 101-117 Finsbury Pavement and 10-12 Finsbury Street site, Islington, will have upon the surrounding residential properties.
The daylight and sunlight review within this report considers residential properties only as they are recognised by the Building Research Establishment (BRE 2011) as having the highest expectation for natural light when compared to other uses – such as commercial. The criteria suggested within the BRE have been used to understand and compare the existing levels of light and the light achieved subsequent to the development of the mixed-use scheme.
GIA have reviewed all development plan policies (the London Plan (Consolidated with Alterations) (2016) as well as GLA Supplementary Planning Documents and Guidance, London Borough of Islington Core Strategy, London Borough of Islington Development Management Policies, London Borough of Islington Finsbury Local Plan, London Borough of Islington Site Allocations Document and London Borough of Islington Supplementary Planning Documents and Guidance.

3.0 Introduction
Daylight and Sunlight
The technical analysis that forms the basis of this report has been predicated against the methodologies set out within the Building Research Establishment Guidelines entitled ‘Site Layout Planning for Daylight and Sunlight – A Guide to Good Practice (2011)’. The guidelines in question are precisely that; guidelines which provide a recommendation to inform site layout and design. They are not mandatory nor do they form planning policy and their interpretation may be treated flexibility depending on the specifics of each site.
The BRE Guidelines provide three methodologies for daylight assessment, namely;
- The Vertical Sky Component (VSC) - The No Sky Line (NSL); and - The Average Daylight Factor (ADF)
There is one methodology for sunlight assessment, denoted as Annual Probable Sunlight Hours (APSH).
Appendix 01 of this report elaborates on the mechanics of each of the above assessment criteria, explains the appropriateness of their use and the parameters of each specific recommendation.
The BRE Guide mentions that usually only residential properties need to be considered for daylight and sunlight, however the guidelines may also be applied to any existing bob-domestic building where occupants have a reasonable expectation of daylight; this would normally include schools, churches, hospitals and Hotels. Within the residential properties, only main habitable rooms such as kitchens, living rooms and bedrooms need to be considered.

4.0 Sources of Information
In compiling this report we have used the following information:
GIA Contextual 3D Model of the Scheme
F!ND OS Map
MSA Surveys 3D Measured Survey of Site (received 28th February 2017)
Make Architects IR11-190617 - Proposed Scheme

20 Ropemaker Street (10358) 4 Manford Properties (BVI) Limited and Daylight and Sunlight Great Elm Assets Limited August 2017
5.0 Assumptions
a) We have relied upon the 3D survey model provided by MSA Surveys to produce the 3D contextual computer model which forms the basis of the technical analysis.
b) All residential buildings have been identified by reference to the Valuation Office Agency (VOA) search and/or external observation.
c) We have not sought access to the adjoining properties thus have made reasonable assumptions as to the internal layouts of the rooms behind the fenestration based upon plans obtained from the Local authorities planning website. This is normal practice where access to adjoining properties is not available.
d) Floor levels have been assumed for the adjoining properties. This dictates the level of the working place which is relevant for the NSL and ADF assessment.

6.0 The Site
The Site is located at 20 Ropemaker Street, 101-117 (Odd Numbers) Finsbury Pavement and 10-12 Finsbury Street, London, EC2. The existing buildings on the Site (see Figure 01) are currently a commercial building with ground floor retail/banking space and office space on the upper floors and consent for two residential caretaker flats at 10-12 Finsbury Street.
The Site occupies the south and south-west corner of an island site bounded by Finsbury Street, Chiswell Street, Finsbury Pavement and Ropemaker Street. It is approximately 400 meters West of Liverpool Street Station and 120 meters north of Moorgate Underground Station.
The existing buildings format is triangular in layout with a ground plus eight storey commercial building on the corner of Ropemaker Street and Finsbury Pavement and has a shared party wall with Vertias House and a ground plus six storey building on 20 Ropemaker Place. With a party wall shared with Finsbury Dials.
Figure 01 – Existing Site
GIA’s understanding of the existing buildings and the surrounding context is depicted within Appendix 02.
20 Ropemaker Street (10358) 6 Manford Properties (BVI) Limited and Daylight and Sunlight Great Elm Assets Limited August 2017
7.0 The Proposal
The Proposed Development (see Figure 02 below) is for the demolition and redevelopment of existing buildings to provide a 27 storey, plus 3 basement levels, building with office use (Class B1) at all basement levels, ground, and upper floors, and flexible retail uses (Class A1/A2/A3) at part lower ground and ground floor levels, along with associated landscaping and works.
We note that the tallest elements of the scheme are located to the west and in keeping with other high rise buildings immediately adjacent, including Citypoint, 25 Ropemaker Street and The Heron.
GIA’s understanding of the scheme is shown on Figure 02 with further drawings located within Appendix 02.

8.0 Surrounding Properties
We have created a 3D dimensional computer model of the Site and the surrounding properties to allow for a detailed daylight and sunlight assessment.
The existing baseline condition of the Site is used to calculate the light conditions received by the key neighbouring buildings, which we can then compare with a calculation of the likely proposed conditions i.e. assuming the Proposed Development is in place.
GIA have located all of the immediate properties surrounding the Site which may be potentially affected by the Proposed Development (see Figure 03 below). In undertaking our research we have been able to establish that just one of the surrounding properties contains residential accommodation, The Heron at 5 Moor Lane, with the other 14 properties being commercial in use. Only The Heron therefore, has been assessed for planning as the BRE guide does not consider commercial properties for daylight and sunlight.

We have undertaken research to understand the internal configurations of The Heron for which we believe the building to consist of a 625 seat concert hall as part of the Guildhall School of Music and Art with the entrance on 1 Milton Street, a 225 seat training theatre, 284 apartments, and an eight storey high atrium in the centre of the building (based on planning ref: 06/01160). From this application we have also obtained floor plans to understand the room uses, which is relevant as only habitable rooms need to be considered.
The tabulated results of the Existing vs Proposed analysis can be found within Appendix 03 of this report and a short commentary of the impacts to The Heron is listed below;

The Heron, 5 Moor Lane
Figure 04 – The Heron
We have assessed The Heron for daylight and sunlight and only considered rooms and windows which are habitable in our review of the impacts. Any impacts to bathrooms, stairwells, circulation space or any commercial space within the building would not be necessary to include within a daylight and sunlight report.
The results of our VSC daylight assessment demonstrate that all windows will fully meet the BRE guidelines with the proposal in place. For the second daylight assessment, NSL, which considers the daylight distribution within the rooms themselves, our results demonstrate there are four rooms, all believed to be bedrooms, which experience transgressions away from the BRE guidance. Of these rooms, two experience losses of light over 20% but less than 23% which would be considered as minor. The other two rooms, (R2/F07 and R2/F08 which have been highlighted in yellow within Figure 05), experience reductions of 28% and 25% respectively from the existing values, which in a dense urban environment such as this, are commensurate. Both rooms are lit to 94% in the existing conditions and are reduced to 67% and 69% lit respectively. They will therefore still receive good levels of daylight with the proposal in place.

With respect to sunlight, we have assessed the windows facing the Site for APSH as they face within ninety degrees due south. The results demonstrate two windows will experience minor transgressions just over 20% away from the existing values for their annual levels of sunlight, and will not lose any winter sunlight. On the basis of our current research, we believe these windows serve circulation space at levels 7 and 9, and as they are not main habitable rooms, they do not need to be considered.
Our results demonstrate that the impacts would be minimal and that the residential accommodation within this building will receive good levels of daylight and sunlight with the proposal in place.

9.0 Conclusions
We have undertaken a daylight and sunlight assessment for the proposed Make Architects scheme for 20 Ropemaker Street, 101-117 Finsbury Pavement and 10-12 Finsbury Street, Islington.
It is important to reiterate that alterations in daylight and sunlight to adjoining properties are often inevitable when undertaking any meaningful development, especially in an urban environment. Therefore, the BRE Guide is meant to be interpreted flexibly because natural lighting is only one of many factors in site layout design. The BRE guidelines suggest that different criteria may be used based upon the requirements for natural lighting in an area viewed against other constraints.
Our daylight and sunlight analysis shows that the vast majority of windows and rooms tested within The Heron will satisfy the BRE guidelines. Our technical analysis shows that for the first daylight assessment, VSC, all windows adhere to the BRE guidance. For the second daylight assessment, NSL, our findings indicate there will be some minimal isolated losses of daylight to four habitable rooms which we believe serve bedrooms and therefore considered less sensitive..
The sunlight APSH assessment demonstrates that all windows serving habitable rooms are compliant with the BRE guidelines.
In conclusion, the impacts recorded to the neighbouring properties are considered acceptable in daylight and sunlight terms.

Appendix 01 Principles of Daylight and Sunlight
Principles of Daylight and Sunlight
Background
The quality of amenity and open spaces is often stipulated within planning policy for protection or enhancement and is often a concern for adjoining properties and other interested parties.
Historically the department of environment provided guidance with the issues, and in this country, this role has now been taken on by the Building Research Establishment (BRE), the British Standards Institutions (BSI) and the Chartered Institute of Building Services Engineers (CIBSE). Fortunately they have collaborated in many areas, to provide as much unified advice as possible in the form of industry best practice.
Many local planning authorities consider daylight and sunlight an important factor for determining planning applications. Policies refer to both the protection of daylight and sunlight amenity within existing properties as well as the creation of proposed dwellings with high levels of daylight and sunlight amenities.
In terms of considering what is material, local authorities typically refer to the BRE guidelines and apply their criteria set out within. The guidelines were originally produced in 1991, but superseded by the BRE guidelines (2011) site layout planning for daylight and sunlight.
Where developers are seeking to maximise their development value, it is often in the area of daylight and sunlight issues that they may seek to push the boundaries. Particularly in London, there is a priority on the creation of more housing thus resulting in the densification of urban areas. Local authorities vary in their attitude of how flexible they can be with the degree of impact on the daylight and sunlight amenity enjoyed by neighbouring owners and it is one factor among many planning aspects considered when determining an application. In city centres where high density is common, the protection of amenity is more challenging and there are many factors that need to be taken into account: each case has to be considered on its own merits.
The BRE Guidelines
The guidelines are typically referred to for daylight and sunlight amenity issues, however they were not intended to be used as an instrument of planning policy. In the introduction of ‘Site Layout Planning for Daylight and Sunlight (2011)’, section 1.6 (page 1), states that:-
“The guide is intended for building designers and their clients, consultants and planning officials. The advice given here is not mandatory and this document 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 because natural lighting is only one of many factors in site layout design (see Section 5). In special circumstances the developer or Planning Authority may wish to use different target values. For example, in an historic city centre, or in an area with modern high rise buildings, a higher degree of obstruction may be unavoidable if new developments are to match the height and proportions of existing buildings".
Again, the paragraph 2.2.3 (page 7) of the document states:-
“Note that numerical values given here are purely advisory. Different criteria may be used, based on the requirements for daylighting in an area viewed against other site layout constraints”.
1
Principles of Daylight and Sunlight
The numerical criteria suggested by the BRE are therefore designed to provide industry advice/guidance to plan/design with daylight in mind. Alternative values may be appropriate in certain circumstances such as highly dense urban areas around London, for e.g. the approach to creating alternative criteria is detailed within Appendix F of the BRE.
Measurement and Criteria for Daylight and Sunlight as set out in the BRE Guidelines
The BRE guidelines state that they are;
“intended for use for rooms in adjoining dwellings where daylight is required, including living rooms, kitchens and bedroom. Windows to bathrooms, toilets, garages need not be analysed.”
They are therefore primarily designed to be used for residential properties however, the BRE guidelines continue to state that they may be applied to any existing non-residential buildings where there may be a reasonable expectation of daylight including; schools, hospitals, hostels, small workshop and some offices.
Daylight
In the first instance, if a proposed development falls beneath a 25 degree angle taken from the centre point of the lowest window, then the BRE suggests that no further analysis is required as there will be adequate sky light (i.e. sky visibility). This rule is applied when considering the scope of any assessments.
The BRE guidelines provide two methods for calculating daylight to existing surrounding properties:
Vertical Sky Component (VSC) No Sky Line (NSL) also referred to as daylight distribution
A further method, the Average Daylight Factor (ADF) is provided for calculating daylight within proposed properties. However, it is sometimes applied as a supplementary assessment for exiting surrounding properties.
Each method is described below:
Vertical Sky Component
Methodology
This is defined in the BRE as:-
“Ratio of that part of illuminance, at a point on a given vertical plane that, is received directly from a CIE standard overcast sky, to illuminance on a horizontal plane due to an unobstructed hemisphere of this sky.”
This statement means, in practice that if one had a totally unobstructed view of the sky, looking in a single direction, then just under 40% of the complete hemisphere would be visible. The measurement of this vertical sky component is undertaken using two indicators, namely a skylight indicator and a transparent direction finder.
2
Principles of Daylight and Sunlight
Alternatively a further method of measuring the VSC, which is easier to understand both in concept and analysis, is often more precise and can deal with more complex instructions, is that of the Waldram diagram.
The point of reference is the same as for the skylight indicator, at the centre of the outward window face. Effectively a snap shot is taken from that point of the sky in front of the window, before and after the obstruction is put in place together with all the relevant obstructions to it, i.e. the buildings.
3
Principles of Daylight and Sunlight
An unobstructed sky from that point of reference would give a vertical sky component of 39.6%, corresponding to 50% of the hemisphere, and therefore the purpose of the diagram is to discover how much sky remains once obstructions exist in front of that point.
Criteria
The BRE Handbook provides criteria for:
(a) New Development (b) Existing Buildings (c) Adjoining Development Land
(a) New Development
Paragraph 2.1.21 of the BRE states that:
“Obstructions can limit access to light from the sky. This can be checked by measuring or calculating the angle of visible sky ‘theta’, angle of obstruction or Vertical Sky Component (VSC) at the centre of the lowest window where daylight is required. If VSC is:
. at least 27% (‘theta’ is greater than 65 degrees, obstruction angle less than 25 degrees) conventional window design will usually give reasonable results. . between 15% and 27% (‘theta’ is between 45 degrees and 65 degrees, obstruction angle between 25 degrees and 45 degrees) special measures (larger windows, changes to room layout) are usually needed to provide adequate daylight. . between 5% and 15% (‘theta’ is between 25 degrees and 45 degrees, obstruction angle between 45 degrees and 65 degrees) it is very difficult to provide adequate daylight unless very large windows are used. . less than 5% (‘theta’ less than 25 degrees, obstruction angle more than 65 degrees) it is often impossible to achieve reasonable daylight, even if the whole window wall is glazed.”
(b) Existing Buildings
Para 2.2.21 (page 11) of the BRE states:
“If any part of a new building or extension measured in a vertical section perpendicular to a main window wall of an existing building, from the centre of the lowest window, subtends an angle of more than 25 degree to the horizontal, then the diffuse daylighting of the existing building may be adversely affected. This will be the case if the vertical sky component measured at the centre of an existing main window is less than 27%, and less than 0.8 times its former value”.
The VSC provides a quick and simple test which looks to give an early indication of the potential for light at the window face. However considered in isolation, it does not, in any fashion, indicate the quality of actual light within a space. It does not take into account the window size, the room size or room use. It helps by indicating that if there is an appreciable amount of sky visible from a given point there will be a reasonable potential for daylighting.
4
Principles of Daylight and Sunlight
(c) Adjoining Development Land
Paragraph 2.3.10 of the BRE guidelines states:
“in broad general terms, a development site next to a proposed new building will retain the potential for good diffuse daylighting provided that on each common boundary:
(a) no new building, measured in a vertical section perpendicular to the boundary, from a point 1.6m above ground level, subtends an angle of more than 43 degrees to the horizontal;
(b) or, If (a) is not satisfied, then all points 1.6m above the boundary line are within 4m (measured along the boundary) of a point which has a VSC (looking towards the new building(s)) of 17% or more 2m above ground level are within 4m (measured sideways) of a point which has a vertical sky component of 27% or more.
Alternative VSC criteria as per Appendix F of the BRE guidelines
The 27% VSC target criteria is based upon a sub-urban type environment whereby a 25 degree line was taken from the centre point on a ground floor window as shown below:
However, in city centre locations and urban areas where density levels are increasing, these values may not be considered appropriate. The BRE guidelines provide that “different targets may be used based on the special requirements of the proposed development or its location” (paragraph F1).
Appendix F of the BRE suggests several approaches as to how alternative targets may be considered including:
. Consented scheme - use of an extant planning permission to establish alternative benchmark criteria for VSC and APSH. It is not appropriate to treat a permitted scheme in the same manner as an existing building and allow a 20% reduction beyond this. If the levels of daylight and sunlight retained are similar to a previously consented scheme then it follows that these levels should be considered acceptable again, notwithstanding other planning considerations. . Mirror massing – to ensure a development matches the height and proportions of existing buildings, the VSC and APSH targets could be set to those of a mirror image of the same height and size, an equal distance away from the boundary (paragraph F5). . Consider surrounding context and existing obstruction angles as well as spacing to height ratios.
5
Principles of Daylight and Sunlight
In addition, due to the requirements for external amenity space within local planning policies, many residential buildings are served by balconies. Balconies can restrict the view of the sky dome whereby even the modest obstruction may result in a large relative impact on the VSC. The BRE guidelines therefore provide that an assessment can be carried out comparing the levels of VSC with and without the balconies in place for both the existing and proposed scenarios, to establish whether it is the presence of the balcony or the size of the new obstruction that is the main factor in the loss of light (paragraph 2.2.11).
No Sky Line
Methodology
The NSL method is a measure of the distribution of daylight at the working plane within a room. The ‘working plane’ means a horizontal ‘desktop’ plane 0.85m in height for residential properties. The NSL divides those areas of the working plane which can receive direct sky light from those which cannot. If a significant area of the working plane lies beyond the NSL (i.e. it receives no direct sky light), then the distribution of daylight in the room will be poor and supplementary electric lighting may be required.
It is similar to the VSC approach in that a reduction of 0.8 times in the area of sky visibility at the working plane may be deemed to be noticeable. It is however, very dependent upon knowing the actual room layouts or having a reasonable understanding of the likely layouts.
It is assessed by plotting the area of a room which can see the sky and which cannot, referred to as the NSL contour or daylight distribution contour. The contours assist in helping to understand the way the daylight is distributed within a room and the comparisons of existing and limitations of proposed circumstances within neighbouring properties. Like the VSC method, it relates to the amount of visible sky but does not consider the room use in its criteria, it is simply a test to assess the change in position of the No Sky Line, between the existing and proposed situation. It does take into account the number and size of windows to a room, but does not give any quantitative or qualitative assessment of the light in the rooms, only where sky can or cannot be seen.
Criteria
BS 8206 Part 2 (para 5.7) that the:
“uniformity of daylight is considered to be unsatisfactory if a significant part of the working plane (normally more than 20%) lies behind the no-sky line”.
Therefore, it is implied that an NSL of at least 80% would be considered satisfactory in regards to deep rooms which are lit by windows on one side, the BRE Guidelines state (para, 2.2.10):
In regards to the alteration as a result of a proposed development or obstruction the BRE provide that the daylight may be adversely affected if “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. “.
6
Principles of Daylight and Sunlight
Average Daylight Factor
Methodology
The Average Daylight Factor (ADF) is defined within the 2011 BRE Guidelines as:
‘a ratio of total daylight flux incident on a reference area to the total area of the reference area, expressed as a percentage of outdoor luminance on a horizontal plane, due to an unobstructed sky of assumed or known luminance distribution’.
Whilst the BRE guidelines provide this measure as a tool to understand daylight within proposed dwellings not existing dwellings, if room layouts are known it can provide a useful supplementary measure of daylight and is often requested by many local authorities.
The ADF method of assessment considers:
The diffuse visible transmittance of the glazing to the room in question (i.e. how much light gets through the window glass). A transmittance value of 0.8% is assumed for single glazing and 0.65% for double glazed windows; The net glazed area of the window in question; The total area of the room surfaces (ceiling, walls, floor and windows); and The angle of visible sky reaching the window(s) in question
In addition, the ADF method makes allowance for the average reflectance of the internal surfaces of the room and of external obstruction (assumed to be 0.5 unless otherwise stated).
Criteria
The criteria for ADF is taken from the British Standard 8206 part II which gives the following criteria based on the room use:
Bedroom – 1% ADF Living room – 1.5% ADF Kitchen – 2% ADF
Where a room has multiple uses such as a living kitchen diner (LKD) or a studio apartment, the highest value is taken so in these cases the required ADF is 2%.
Sunlight
Methodology
The BS 8206 part 2 (section 5.2) states that:
“Provided that the entry of sunlight is properly controlled, it is generally welcome in most buildings in the UK. Dissatisfaction can arise as much from the permanent exclusion of sunlight as from its excess. The provision of sunlight is important in dwellings, particularly during winter months. Sunlight is especially valued in habitable rooms used for long periods during the day.”
7
Principles of Daylight and Sunlight
Sunlight is measured using a sun indicator which contains 100 spots, each representing 1% of Annual Probable Sunlight Hours (APSH). Where no obstruction exists the total APSH would amount to 1486 hours and therefore each spot equates to 14.86 hours of the total annual sunlight hours.
The number of spots is calculated for both the whole year and also during the winter period (21st September to 21st March) prior to an obstruction and after the obstruction is put in place. This provides a percentage of APSH for each of the time periods for each window assessed. The 2011 BRE Guidelines note that:
“In housing, the main requirement for sunlight is in living rooms, where it is valued at any time of day, but especially in the afternoon.”
“all main living rooms of dwellings…should be checked if they have a window facing within 90° of due south. Kitchens and bedrooms are less important, although care should be taken not to block too much sun”;
“If the main living room to a dwelling has a main window facing within 90° of due north, but a secondary window facing within 90° of due south, sunlight to the secondary window should be checked.”
“…a south facing window will, in general, receive most sunlight, while a north facing one will receive it only on a handful of occasions. East and west facing windows will receive sunlight only at certain times of day”.
When a room has multiple windows, not all may have a southerly orientation however, these windows may contribute to the levels of sunlight within a given room even if by 1-2% APSH. As well as the assessment on a window basis the BRE guidelines provide that an assessment can be undertaken on a room basis.
Whilst the emphasis of the BRE guidelines is in regards to living rooms, it is not always possible to determine the room uses within all of the properties assessed and therefore typically all windows or all rooms with windows facing within 90 degrees of due south and facing the site are assessed.
Criteria
The BRE provide that for existing buildings a window maybe adversely affected if a point at the centre of a window receives:
Less than 25% of the APSH during the whole year, of which 5% APSH must be in the winter period; and Receives less than 0.8 times its former sunlight hours in either time period; and Has a reduction in sunlight for the whole year more than 4% APSH.
In terms of the assessment on a room basis the criteria applied is the same.
For proposed buildings the BRE provide (paragraph 3.1.15) that a dwelling or building which has a particular requirement for sunlight will appear reasonably sunlit provided:
At least one main window faces within 90 degrees of due south; and
8
Principles of Daylight and Sunlight
Centre of one main living room window can receive 25% of APSH including 5% APSH in the winter months.
It continues that where groups of dwellings are planned the layout should aim to maximise the number of living rooms that meet the above recommendations.
Overshadowing
As well as daylight and sunlight amenity to neighbouring dwellings, planning policy often refers to the levels of overshadowing to amenity areas such as parks, public squares, playgrounds etc. The BRE guidelines provide two methods of calculation in regards to overshadowing which are as follows:
Sun Hours on Ground
Methodology
This method of overshadowing assessment uses the sun on ground indicator to determine the areas which receive direct sunlight and those which do not. This method applies to both new and existing areas of amenity space. The BRE Guidelines suggest that the Spring Equinox (21st March) is a suitable date for the assessment as this is the midpoint of the suns position throughout the year. Using specialist software, the path of the sun is tracked to determine where the sun would reach the ground and where it would not.
Criteria
The BRE guidelines recommend that at least half of an amenity space should receive at least two hours of direct sunlight on March 21st. In regards to existing spaces where the existing sunlit area is less than half of the area, the area which receives two hours of sunlight should not be reduced by more than 20% (it should retain 0.8 times its former value).
Transient Overshadowing
The BRE guidelines suggest that where large buildings are proposed which may affect a number of gardens or open spaces, it is useful to plot a shadow plan to illustrate the location of shadows at different times of the day and year. For the purpose of this assessment, shadow has been mapped at the following times of the year:
21st March (Spring equinox) 21st June (Summer solstice) 21st December (Winter solstice)
The September equinox is not assessed as this would provide the same results as those for March 21st.
For each of these dates the overshadowing is calculated at hourly intervals throughout the day however some images may not be present given the early sunset during the Winter period.
The BRE guidelines do not provide any criteria for transient overshadowing. Therefore the analysis provides a description of where additional shadow is cast as a result of a development with professional judgement to determine the effect comparing the shadow resulting from the proposed development against that of the existing site.

Principles of Daylight and Sunlight
Light pollution and Solar Glare
Light pollution is defined as any light emitting from artificial sources into spaces where it is not wanted for example from offices into neighbouring residential properties where it could cause a nuisance. The ILP Guidance notes provide details of how to measure light pollution and criteria based on the urban density of the respective area to determine the acceptability of the light levels.
Solar glare is particularly important at pedestrian and road junctions as well as along railway lines where the glare can cause a temporary blinding to drivers or pedestrians. Glare can occur from reflective materials such as glazed areas or metal cladding on the facades. This assessment is therefore undertaken from viewpoints surrounding the site at junctions and positioned at the driver’s eye level. Focal points are dictated by the location of signals or oncoming traffic.
Other Amenity Considerations
Daylight and sunlight is one factor among many under the heading of residential amenity considerations for any given development design or planning application; others include:
outlook sense of enclosure privacy access to outdoor space e.g. balconies or communal garden/courtyard
