Key Findings

  • 01One building was identified as more prone to overheating due to its orientation and window-to-floor ratio.
  • 02Renovation efforts in the studied houses contributed to an increased risk of overheating.
  • 03Danish terraced houses exhibit similar overheating tendencies to multi-family buildings and a higher potential than single-family houses.

Application

Design takeaway

Integrate detailed thermal comfort analysis into the design process for building renovations, paying close attention to orientation and fenestration to prevent unintended overheating.

How to apply

When designing renovations for residential buildings, use thermal simulation tools to predict overheating risks and adjust design elements like insulation, ventilation, and window specifications accordingly.

Project actions

  • 01When researching building designs, look for studies that consider how people will feel inside the building, not just how much energy it uses.
  • 02Consider how different design choices, like window size and placement, might affect the temperature inside a building.
03

Method & Evidence

AimTo what extent do building renovations in Danish terraced houses contribute to or mitigate overheating, and how does this compare to other building typologies?
MethodBuilding performance simulation
ProcedureFour typical Danish terraced houses were simulated for their thermal performance, first in their existing state and then after renovation, using building performance simulation software.
ContextResidential buildings (Danish terraced houses)

Variables

IVRenovation status (existing vs. renovated)
DVOverheating risk/temperature
CVBuilding typology (Danish terraced houses), orientation, window-to-floor ratio
04

Strengths & Limitations

Strengths

  • +Uses building performance simulation for a quantitative assessment.
  • +Compares pre- and post-renovation scenarios.

Limitations

Simulations are models and may not perfectly reflect real-world conditions. The specific context of Danish terraced houses might limit direct applicability to other regions.

Reliability & validity

The validity of the findings relies heavily on the accuracy of the building performance simulation software and the input data. Reliability would be enhanced by comparing simulation results with actual on-site measurements.

Think critically

If renovations can worsen overheating, what design strategies can be employed during the renovation process to actively mitigate this risk, rather than just avoid exacerbating it?

05

Design Principles

"Optimize building design and renovation strategies to ensure thermal comfort throughout the year, considering both energy efficiency and occupant well-being."

Designers and engineers must consider the thermal comfort implications of renovation strategies. Failing to address potential overheating can negate energy savings and negatively impact the well-being of building occupants.

06

What This Means for Your Design

When you renovate houses, sometimes they can get too hot inside, especially if they face the wrong way or have too many windows. This can make people uncomfortable and unhealthy.
