Summer Overheating & Thermal Comfort Analysis Reports

Whitecode Design Associates Ltd are experienced in assessing buildings against a variety of overheating methodologies, from BREEAM Hea 04 to TM59:2017. Our experience has been across a wide variety of projects, from small commercial units to large mixed-use developments. Our employees are accredited Integrated Environmental Solutions Virtual Environment (IES VE) software users who will always strive to provide the client with a working solution if it is determined there is a risk of overheating in a building.

ACCREDITATIONS

Whitecode Design Associates Ltd have accredited IES VE software users.

A leading global innovator of integrated 3D Sustainability analysis technology. Supporting the creation and management of efficient, healthy and affordable built-environments.

Whitecode Design Associates Ltd use IES VE which is a 3D modelling and dynamic simulation programme.

Dynamic simulations allow multiple scenarios to be modelled to find the optimum solution in a short time period.

IES VE has a lot of input options allowing for the model to be very detailed and therefore, giving very accurate results.

The accurate results reduce the risk of remedial works having to be carried out as well as making sure the occupant is thermally comfortable in the summer months.

Using the detailed results, Whitecode Design Associates Ltd will always aim to suggest a viable specification which will reduce the risk of summer time overheating.

As Summer Overheating and Thermal Comfort Analysis Reports for new-build developments are completed from architectural plans, sections and elevations, Whitecode are able to carry out these works across the country.

We have mainly carried out assessments for large scale high-rise residential developments located within London, but have also carried out assessments for small scale developments consisting of offices, schools and commercial units and small apartment blocks and houses.

FAQS

What causes overheating in buildings?
As buildings have become better at preventing heat loss in winter, the risk of overheating in the summer months has increased. Also, the UK is experiencing hotter summers as the climate changes making buildings reach uncomfortable or excessive temperatures. The aspiration to have large expanses of floor to ceiling glazing leads to an increase in solar heat gains entering the building, which is then trapped due to the building being designed to keep heat in. In a self contained dwelling, uninsulated pipework can lead to unwanted heat being distributed through the house. This may seem minimal, but with low-energy buildings, even minimal amounts of extra heat can lead to a big increase in the risk of overheating. Also, most new apartment buildings will be part of a community/district heating scheme. Uninsulated community pipework can cause overheating in dwellings as well as common areas. This would also have an effect on the efficiency of the community heating scheme. Having inadequate controllable purge ventilation is also a major cause of overheating. As buildings become more airtight it becomes easier for heat to become trapped inside. The occupants can be the main cause of overheating in buildings. If the occupants do not know how to use the building as designed, then it can lead to uncomfortable temperatures being reached.
What can we do to reduce the risk of overheating?
The risk of overheating can be reduced by minimising solar and internal heat gains, having an adequate purge ventilation strategy or providing occupant controlled mitigation measures. Another key factor is educating the occupant on how the building was designed to reduce the risk of overheating Reducing the solar and internal heat gains will keep the internal temperatures lower, which directly reduces the risk of overheating. By providing an adequate ventilation strategy, any heat that is trapped in the building can be purged out. The increase in air movement also makes the occupant feel cooler. However, the ventilation should be able to be controlled in the winter as a pleasant cooling breeze in the summer can be an annoying cold draught in the winter. Providing occupant controlled mitigation measures allows thermal comfort of the building to be adapted to suit the changing outdoor climate. This can be in the form of internal blinds or movable external shading. This allows solar gains in the winter to be benefited from, whilst reducing the unwanted solar gains in the summer. It could be argued that educating the occupant on how to keep cool is the most important method of reducing the risk of overheating. If the occupant is unaware on how to use the overheating mitigation measures designed for the building, then the measures will not work as designed and the risk of overheating will increase.
Can you produce compliant thermal comfort reports for BREEAM issue Hea 04?
Yes. As we have in house BREEAM assessors, we are able to produce compliant thermal comfort reports including assessing against a projected climate change scenario.
