Addressing Corridor Overheating on Developments with Community Heating

The increased use of community heating and CHP in residential apartment schemes can lead to excessive overheating in corridors. Our dynamic modelling estimates that temperatures can reach 50oC unless mitigation measures are designed in from the outset. The heat gains are due to hot water being circulated throughout ceiling voids in the corridors and risers [...]

Microclimate Analysis – a key to Planning

Micro-scale environmental issues such as overshadowing, light pollution, air quality, wind and daylight provision are becoming increasingly important to planners as recognition grows of the climate impacts of buildings as urban densities and building heights increase. Major planning applications often require a Microclimate Analysis Report. With the use of the Computational Fluid Dynamics (CFD) we [...]

Big Heat Bills Make Community Heating Inappropriate for Small Developments

A community heating strategy with Combined Heat & Power (CHP) can have a big impact on resident heat bills. This is particularly the case for smaller developments of less than 100 homes where heat bills can be 50% higher than with individual gas boilers. To avoid being committed to an energy strategy that results in [...]

Glazing Implications of Part L1A 2013

Glazing is already a key focus area for environmental assessment, driving internal daylight levels, thermal comfort, and overheating risk.  Our initial assessment using Part L 2013 shows the increasing importance of early consideration of the energy and CO2 impacts of glazing design. The strategic issue is that the benchmark notional building used in SAP 2012 [...]
