Traditional Building Performance

There is a significant lack of relevant research and data for traditional building performance (both existing structures and retrofitted), however there is no short term fix for this issue. Materials, features and users of buildings interact in complex ways that require a holistic and systemic approach. There are also values and aims with regard to […]

Fabric and Human Health

There are two areas in which breathable conditions are vital. These are fabric health and human health. In certain circumstances, building fabric can be damaged due to a lack of breathability, and human health can be affected due to a build-up of mould. Mould spores are incredibly small and can even penetrate solid rock. Damp […]

What is “The Performance Gap”?

What do we mean by the “performance gap” when we talk about buildings? When a building is designed, there is a targeted level of energy performance. Once a building is completed however, the reality is that these targets often aren’t achieved. The focus at the moment is on closing the gap between intended and actual […]

Low Energy & Low Carbon

60% of all energy used in domestic dwellings is through space heating. This is an extremely high percentage and is much higher than any other source of energy loss. However when it comes to creating energy efficiency in buildings, the focus is often on other areas of energy consumption. There has been quite a lot […]

Breathability and Natural Materials

When we talk about “breathability” in buildings, we aren’t referring to the movement of air within a building, rather the movement of water. Water moves in and out of buildings constantly as both a liquid and as a gas, and is practically everywhere; inside the building, outside, in the walls, floors and roofs. Breathability is […]

Scrapping The Zero Carbon Homes Policy

It has recently been announced that the zero carbon homes policy is to be scrapped by the British government. Established in 2006, the policy would have meant that within ten years, all new residential buildings would be low in energy use and generate its own energy for that which remained such as hot water, lighting […]

The Importance of Materials

We have previously discussed the misconceptions about the financial cost of natural materials in energy efficient homes. While costs may, in some cases, be higher than synthetic insulations the gap is often much smaller than people realise, if at all. With the added advantage of enhanced comfort and the significantly reduced risk to health and […]

High Energy Performance in New Builds

Passive House buildings are found to be almost four times as efficient as other high energy performance buildings. In an article published by an independent group (D. Johnstona, D. Farmera, M. Brooke-Peata & D. Miles-Shenton) the heat loss coefficients of 25 new UK building projects that all boasted “high energy performance” were measured. As part […]
