24 Degrees - Optimum Temperature?

Jul 17, 2011 |NBS

Air-conditioning systems consume a lot of energy. We all know that high energy use means carbon emissions – which is bad! Indeed, the trend for carbon management strategies (not to mention the now-live CRC Energy Efficiency Scheme) clearly shows that it just is not 'cool' to be a high energy user. Yet air-conditioning is often seen as a necessity, in order to cool buildings and to maintain a comfortable and productive working environment. So there is the dilemma: be an evil high energy user, or have a hot, sweaty building that is unpleasant to work in! The good news is that businesses could actually reduce emissions and save on fuel bills simply by better management of air-conditioning use. The even better news is that it is a simple, low-cost solution. In this programme, we look at the 24°C Project which was undertaken by British Council for Offices (BCO).

Visqueen launches Ultimate Self Adhesive Membrane for hydrocarbon and VOC-contaminated sites

The construction industry faces growing challenges when building on increasingly complex brownfield sites. Alongside the need for effective waterproofing, developers and contractors must now address a wider range of ground contaminants, including hydrocarbons, volatile organic compounds (VOCs), and hazardous ground gases, while maintaining programme efficiency and installation quality. Against this backdrop, Visqueen has expanded its gas protection and waterproofing portfolio with the launch of Visqueen Ultimate Self Adhesive Membrane, a new hydrocarbon and VOC-resistant self-adhesive tanking membrane. Developed as the latest addition to the Visqueen non-foil gas barrier range, the new membrane combines proven gas barrier and waterproofing performance to help specifiers address multiple site challenges with a single solution.

Siderise: Helping to bridge the gap between Gateway 2 approval and on-site fire protection

While the new building safety regime hasn’t fundamentally changed what requirements higher-risk buildings (HRBs) must meet to comply with the Building Regulations, it has significantly increased the breadth, depth and volume of evidence that must be supplied to demonstrate this. As a result, project teams have had to adapt the way they work and even look beyond their roles to understand how their actions may impact the next Dutyholder in the chain. For specifiers, this can include considering what supporting services are offered with life safety-critical elements to enable correct design, installation and maintenance. Early engagement with manufacturer technical specialists can help identify any practical challenges that may arise onsite. Then, during construction, these services can help support the translation of design intent into reality so that buildings are safe for occupation.
