Colour use in building design

Colour is a powerful form of communication, we are either attracted to colour and repelled by it, so even if the coolest architectural design were presented to us, if we didn’t like the colour, we wouldn’t like it at all.

Colour in design is very subjective. What evokes one reaction in one person may evoke a very different reaction in someone else. Sometimes this is due to personal preference, and other times can be due to cultural background.

Using Warm Colours

Warm colours include red, orange, and yellow, and variations of those three colours. These are the colours of fire, autumn, and of sunsets and sunrises, and are generally energizing, passionate, and positive.

Red and yellow are both primary colours, with orange falling in the middle, which means warm colours are all truly warm and aren’t created by combining a warm colour with a cool colour. Warm colours are used in designs to reflect passion, happiness, enthusiasm, and energy.

Using Cool Colours

Cool colours include green, blue, and purple and are often more subdued than warm colours. They are the colours of night, of water, of nature, and are usually calming, relaxing, and somewhat reserved.

Blue is the only primary colour within the cool spectrum, which means the other colours are created by combining blue with a warm colour. Greens take on some of the attributes of yellow, and purple takes on some of the attributes of red. Cool colours are used in designs to give a sense of calmness or professionalism.

Using Neutral Colours

Neutral colours often serve as the backdrop in design. They’re commonly combined with brighter accent colours. But they can also be used on their own in designs, and can create very sophisticated layouts. The meanings and impressions of neutral colours are much more affected by the colours that surround them than are warm and cool colours.

Whatever the colour, architecture is becoming brighter and bolder and soon city landscapes will no longer be grey and brown but will have many different colours and accent lighting.

The future of Tennis at Wimbledon

Wimbledon’s famous Court No 1 is on it’s was to having a retractable roof after a £70 million modernisation of the all England Club was given the green light back in 2014.

A seven-year masterplan to upgrade the home of tennis at SW19 with a retractable roof, designed to be closed in 10 minutes when rain starts to fall, with play resuming within half an hour after it stops — minimising hold-ups for the court’s 11,500 spectators.

The club hopes it will also mean play on both main show courts will now be able to continue until the 11pm deadline without fear of losing light. Construction of the Court One roof comes five years after Centre Court was given its £150 million retractable cover.

Work has already started prior to this year’s tournament and will continue in phases to avoid disruption.


The project will also see improved facilities and a giant new TV screen built near “Murray Mount”.

The All England Lawn Tennis Club’s junior programme will move into temporary courts beneath a dome on nearby playing fields, while Court 19 will be bulldozed and replaced by a public plaza with a courtyard and gardens.


Sun Control and Solar Shading

There are many different reasons why people would want to control the amount of sunlight that is admitted into a building. In warm, sunny climates excess solar gain may result in high cooling energy consumption; in cold and temperate climates winter sun entering south-facing windows can positively contribute to passive solar heating; and in nearly all climates controlling and diffusing natural illumination will improve overall day lighting.

sun-control-4Well-designed sun control and shading devices can dramatically reduce building peak heat gain and cooling requirements and improve the natural lighting quality of building interiors. Sun control and solar shading devices can also improve user visual comfort by controlling glare and reducing contrast ratios. Shading devices offer the opportunity of differentiating one building facade from another. This can provide architectural interest and human scale to an otherwise undistinguished design.

The use of sun control and shading devices is an important aspect of many energy-efficient building design strategies. In particular, buildings that employ passive solar heating or day lighting often depend on well-designed sun control and shading devices.

During cooling seasons, external window shading is an excellent way to prevent unwanted solar heat gain from entering a conditioned space. Shading can be provided by natural landscaping or by building elements such as awnings, overhangs, and trellises. Some shading devices can also function as reflectors, called light shelves, which bounce natural light for day lighting deep into building interiors.

The design of effective shading devices will depend on the solar orientation of a particular building facade. For example, simple fixed overhangs are very effective at shading south-facing windows in the summer when sun angles are high. However, the same horizontal device is ineffective at blocking low afternoon sun from entering west-facing windows during peak heat gain periods in the summer.

Exterior shading devices are particularly effective in conjunction with clear glass facades. However, high performance glazing are now available that have very low shading coefficients (SC). When specified, these new glass products reduce the need for exterior shading devices.

In the summer, peak sun angles occur at the solstice on June 21, but peak temperature and humidity are more likely to occur in August. Remember that an overhang sized to fully shade a south-facing window in August will also shade the window in April when some solar heat may be desirable.

To properly design shading devices it is necessary to understand the position of the sun in the sky during the cooling season. The position of the sun is expressed in terms of altitude and azimuth angles.

Shading devices can have a dramatic impact on building appearance. This impact can be for the better or for the worse. The earlier in the design process that shading devices are considered the more likely they are to be attractive and well integrated in the overall architecture of the project.

Architecture today uses shading devices not just as a practical necessity but also to enhance the architectural nature of a design.




Sunshine at the JPG Annual Golf Day

Over 30 guests attended our annual Golf Day this year at Cookridge Hall, Leeds, with everyone playing from their full handicap on this par 72 course.

The course itself challenged a few players with 9 water holes and the tricky feature, hole number 6 with a par 3, which is over water with a two tier green.

The day started well with everyone remembering their clubs and good form from the 1st tee-off. Some great positions and noises were heard from various guests and it looked like it could be a pretty close round.

By the time everyone had made it to the 9th hole, you could see the confidence had waned a little with a few people now doing the grass walk and the tree studying in order to retrieve their lost balls.

On the 9th hole in particular everyone seemed to be favouring the trees on the right, with some loud rustling and branch cracking.

The final hole is right in front of the clubhouse where they were greeted with a cold beer and some hearty food.

The winning team of the day were; Jason Stowe, Andrew Cooper, James Winter, Nick Child with a hugely impressive 102 points.

The top 3 golfers of the day were Jason Stowe in 1st place with 44 points, Mark Cooper in 2nd place with 40 points and Alan Sheard in 3rd place with 39 points. Our very own Managing Director, Chris Harding did not make the top 3!

Nearest the pin on the 6th hole was Simon Dixon, with another nearest the pin on the 18th hole came from one of JPG’s Directors Matthew Potter. Simon Rispin managed the longest drive of the day.

A mention must go to Nicholas Prescott who worked extremely hard throughout the course with his great magic trick of vanishing balls.

We hope you enjoyed it as much as we did!
