COOL NIGHTS AHEAD
Night ventilation is a low-energy strategy for cooling a building, thus providing a more comfortable environment for the occupants during hot daytime periods. bre has produced an information paper on the effective use of this technique in office buildings, and refers to a computer-based pre-design tool developed to help with decisions about the suitability of night ventilation for office buildings.

The current Building Regulations require floors and roofs to be tied or strapped to the walls to maximise the stability and robustness of the structures. While this occurs naturally in frame structures, it must be considered at the design stage for masonry structures. New structures can be built with this requirement in mind, but many older buildings do not meet it. The latest bre Good Building Guide gives advice in two parts. Part 1 examines a number of retro-fit fixing systems that can bring structures up to modern safety standards, alleviate bulging in walls and other related stability problems. Part 2 considers the design and performance issues of wall and floor ties.

MAKING LIGHT WORK
Daylight is an essential component of a visually attractive and energy- efficient atrium building but there are a number of aspects to consider: the atrium needs enough light for circulation purposes and to sustain plant growth; good control of electric lighting is vital for energy efficiency; areas surrounding the atrium can suffer from poor penetration of natural light unless care is taken in design, and solar shading must be taken into account. An information paper addresses these issues.

BUILDING ON FILL
The scarcity and cost of suitable land are leading to the development of sites with deep deposits of fill. A digest provides guidance for low- rise buildings on fill in three parts: Part 1 - Classification and load- carrying characteristics; Part 2 - Site investigation, ground movement and foundation design; Part 3 - Engineered fill. bre Digest 427 Low-rise Buildings on Fill. £13.50
