Everything you need to know about a Overheating Part O Report…

What are overheating calculations?

Overheating calculations assess the potential for high indoor temperatures in buildings. They’re essential for ensuring thermal comfort without excessive energy use for cooling. There are two main methods for conducting these calculations:

1. Simplified Method: This approach provides a quicker assessment of overheating risk. It’s based on the principle that overheating is exacerbated by excess solar radiation and insufficient ventilation. The calculations use basic assumptions and generalized data to estimate the risk of overheating.

2. Dynamic Thermal Modelling: This method involves more detailed simulations using computer models. It considers factors like building materials, insulation, solar gain, and ventilation. Dynamic thermal models provide a comprehensive analysis of thermal behavior but require more time and expertise.

Our assessment team can help you understand the appropriate method for your project,

Why are overheating calculations needed:

Overheating risk can impact occupants’ comfort and energy efficiency, so it’s crucial to address it during building design and construction. Overheating calculations are essential for several reasons:

1. Comfort and Well-Being: Overheating can lead to discomfort, fatigue, and health issues for occupants. By assessing the risk of overheating, you can design buildings that maintain a comfortable indoor temperature.

2. Energy Efficiency: Overheating increases the need for cooling systems (like air conditioning), which consume energy. Proper calculations help optimize energy use and reduce costs.

3.  Building Regulations: To meet current building regulations it is necessary for constructed building to meet or better the values set out by Part O. Without them, building control cannot sign off the development and the property cannot be let or marketed for sale. Compliance ensures safe and habitable buildings.

4.  Sustainable Design: Overheating affects a building’s environmental impact. By addressing it, you contribute to sustainable, long lasting, usable buildings.

Overheating calculations report timescales

We use the most up to date software for our overheating calculations and reports. For an experienced company like Construction Assessments and Surveys Ltd, the time scales usually fall into the following categories:

• Overheating calculation and report - Simplified Method Around 1 – 2 weeks

• Overheating calculation and report - Dynamic Thermal Modelling Around 1 – 2 weeks

Faster service times can be provided subject to availability.

Overheating calculations

With over a decade of experience our assessors have a wealth of energy performance knowledge that can be applied to your project to calculate overheating. Not only are we able to complete your calculations quickly and efficiently, but working with us also has the following benefits:

• We provide you with fixed prices and no hidden extras

• You get a dedicated assessor with expert knowledge 

• To make everything as simple as possible, you can book over the phone

• We save you money by reducing delays

Our energy assessors can help you and your designer or architect to clarify the overheating of a new dwelling, commercial property, extension or renovation. We are experts in design, energy performance and technologies and can help you make informed choices to achieve compliance.

The Overheating calculation Process

Before we begin calculations, we start by asking you a few key questions and asking you to provide us with information on your project. With an accurate set information provided, we can test your design for overheating. You should expect to receive your report within the times quoted. Occasionally, the challenges of your project are especially demanding, in which case we will contact you directly to advise you when you should expect your report.

When do I need overheating calculations

To offer most value to your project we advise engaging us for water efficiency calculations as early as practically possible. That way can help you make informed choices to achieve compliance. We are often instructed during RIBA stage 2-4 prior to a building control application being made.

What do you get

Once you provide us with detailed information on your project we will prepare and provide you with:

• Water Efficiency calculations

• A summary report of findings and recommendations

What happens if my overheating calculations do not pass?

If your water efficiency calculations indicate that your building does not meet compliance standards, don’t worry! Our assessors are ready to offer practical advice and guidance. They can advise on necessary adjustments to improve overheating potential on your project.
