Good Daylight: Quantity or Quality?

Posted on May 16th 2016

Average Daylight factor (ADF) can be a valuable tool for assessing the quantity of internal daylight amenity. However, where the quality of the internal daylight needs to be considered, more appropriate metrics can be used such as Useful Daylight Illuminance (UDI). ADF continues to be the standard metric used to assessing daylight amenity of new buildings. This simple assessment establishes …

Electricity key to CHP economics & low resident heat prices

Posted on May 11th 2016

Obtaining value for electricity generated from CHP engines is a critical issue in order to make operating CHP engines economically attractive and thereby minimising resident heat costs. This is because there are two outputs of a CHP engine: heat & electricity, as opposed to just heat from a boiler. Without obtaining value for the electricity, CHP engines are just an …

Caution urged for connection to area-wide heat networks

Posted on April 6th 2016

It is becoming increasingly common for planning authorities to require developments to commit to connecting to existing or future planned area-wide heat networks. From our experience, extreme caution should be taken in considering whether this is reasonable and in the best interests of the development and its future residents. The theory behind district heating is that bigger heat networks are …

Cost Benefits of Thermal Bridging Analysis

Posted on February 18th 2016

Thermal bridging analysis to improve Part L performance offers a highly cost-effective way to improve building quality and achieve carbon dioxide reduction targets. Carrying out the analysis should be considered for all construction types being assessed under Part L 2013, even if bespoke calculations are required to ascertain accurate linear thermal transmittance values (psi-values). Our analysis has indicated that, for …

Active Water Management: New Technology for Attenuation

Posted on February 12th 2016

Our clients are showing interest in a new approach to water management. Active water management attenuation systems allow the outflow of stored water to be fully controlled, in contrast to a passive system which continuously drains at a set discharge rate. This control allows the attenuated water to be used for purposes which would otherwise require separate tanks, such as firefighting water …
