Abstract

Schools and universities in particular have high day-time use and crowded conditions. Temperatures can soar by midday, making it difficult for students and lecturers to focus. However, installing air-conditioning can result in unacceptably high running costs. Clay bricks have well-known thermal insulating properties, making buildings naturally cooler in summer and warmer in winter. This saving is further enhanced by designing the building with cavity walls (a double leaf wall with an air cavity in-between). Unlike other building materials, the high thermal mass of clay brick prevents a ‘hot-box’ effect in high summer temperatures. Rooms stay considerably cooler than ambient temperatures, allowing students to concentrate throughout the day.
