Role of Architects in the thermal performance of a facade.

Architects play a critical role in ensuring that buildings are energy efficient and comfortable for their occupants. One of the most important aspects of building design is the facade, which is the exterior of the building. The facade is responsible for regulating the flow of heat and air into and out of the building, and it can have a significant impact on the building's energy consumption.

That's why it's important for architects to understand the thermal performance of a building facade. Thermal performance is a measure of how well a material or structure resists heat flow. A facade with poor thermal performance will allow heat to easily transfer from the inside to the outside, and vice versa. This can lead to uncomfortable indoor temperatures, as well as increased energy bills.

There are a number of factors that can affect the thermal performance of a building facade, including the materials used, the design of the facade, and the climate in which the building is located. Architects need to take all of these factors into account when designing a facade that is both energy efficient and aesthetically pleasing.

Here are some specific things that architects can do to improve the thermal performance of a building facade:

• Use materials with high thermal resistance, such as insulation.
• Design the facade to minimize thermal bridging, which is where heat can easily flow through a weak point in the facade.
• Orient the facade to take advantage of solar gain in the winter and shade in the summer.
• Use overhangs and balconies to shade the facade from the sun.
• Install solar panels on the facade to generate renewable energy.

Regulation Requirements:

Architects are required to meet the requirements as per Building Regulations Part L, which includes the requirement that minimum internal surface temperatures be such that condensation risk is minimized and mould growth avoided.?

Approved Document L1A (L2A for non-residential buildings) cites the BRE Information Paper IP1/06 (Assessing the effects of thermal bridging at junctions and around openings).

Building Regulations in England and Wales require thermal bridging to be considered in fabric heat loss calculations for residential construction. The latest version of the regulations (2021) has increased U-value requirements, making thermal bridging even more important. Maximum U-values have been decreased, and the U-values of the notional building have also been reduced.

According to L1A (2021) (4.188 option d), the default additional heat loss through thermal bridges (y-value) has increased by 33%, from 0.15 to 0.20.

How to tackle this issue:

Thermal performance is a critical factor in the design of building facades. A facade with poor thermal performance can lead to uncomfortable indoor temperatures, increased energy bills, and even condensation and mold growth. That's why it's important for architects to use thermal analysis and U value calculation software to determine the thermal performance of their facade designs.

Thermal analysis software can help architects to model the heat flow through a building facade. This allows architects to identify potential areas of thermal bridging, where heat can easily flow through a weak point in the facade. Thermal bridging can significantly reduce the thermal performance of a facade, so it's important to identify and address it in the design phase.

U value calculation software can help architects to calculate the U value of a building facade. The U value is a measure of how well a material or structure resists heat flow. A lower U value indicates better thermal performance. Architects can use U value calculation software to compare different facade designs and choose the one with the best thermal performance.

Here are some additional benefits of using thermal analysis and U value calculation software for facade thermal performance:

• Improved decision-making: Thermal analysis software can help architects to make better decisions about the materials and design of their facades. This can lead to improved thermal performance, reduced energy costs, and increased occupant comfort.
• Reduced risk of costly mistakes: Thermal analysis software can help architects to identify and avoid costly mistakes in their facade designs. This can save time and money in the long run.
• Increased compliance with building codes: Thermal analysis software can help architects to ensure that their facade designs comply with building codes. This can protect them from costly fines and penalties.

If you are an architect, we encourage you to use thermal analysis and U value calculation software to determine the thermal performance of your facade designs. These softwares can help you to create energy efficient and comfortable buildings that meet or exceed building codes.

There are many different thermal analysis and U value calculation software programs available on the market. One of the most popular programs is Flixo Pro.
