Temperature differences occur across different orientations or elevations of a building. Several factors contribute to this variance, including solar exposure, wind patterns, shading, building materials, and surrounding structures.

On June 15, 2023, the UK government introduced new building regulations that aim to reduce carbon emissions and improve indoor air quality in buildings. These regulations, which apply to all new buildings and major alterations to existing buildings, include:

The generation of heat beneath solar PV panels is an inherent characteristic of the photovoltaic process. While solar panels efficiently convert sunlight into electricity, they inevitably produce heat as a byproduct. Factors such as solar irradiance, panel design, and material properties influence the extent of heat generation.

Part O requires all new buildings to have a mechanical ventilation system that provides fresh air to the building and removes stale air. The system must be designed and installed to ensure that the indoor air quality in the building is maintained at a satisfactory level.

Mechanical Ventilation with Heat Recovery (MVHR) is a popular ventilation system in modern, energy-efficient buildings. MVHR provides fresh, filtered air while reducing heat loss. Here are some frequently asked questions about MVHR:
