Daylight
For many, city living has it all and is the best place to live. This belief can be attributed to common themes;

  • Access to work place, educational, medical, retail and leisure facilities
  • Transport links and reduced travel times
  • Cultural benefits with social possibilities and networking

With this, many developers still see building development in city and brownfield sites as a key area of focus. However residential development poses some interesting challenges perhaps none more so than with respect to visual amenity;

  • Views and privacy
  • Quality and availability of sunlight

Whenever new development is planned there are a number of key parties all with their own interests:

  • The development team eager to gain planning permission whilst minimising risk and associated delay
  • Existing Building Owners and Residents who may be impacted by new developments
  • New Building Owners and Residents keen to ensure they maximise visual amenity

Privacy, daylight, sunlight and immediate outlook are all import factors and should be considered as early as possible in the design stage.

Early daylighting analysis using 3D modelling techniques will improve understanding and mitigate the risks. Using a low cost modelling approach at each design stage helps avoid costly abortive design and construction works.

Daylight, Sunlight and Overshadowing (DSO) assessment can include tests for a range of factors that designers use to make the right decisions:

  • Average Daylight Factor – the amount of daylight in a given space reported as %
  • Annual Probable Sunlight Hours – the expected number or % of sunlight hours for a reference point
  • Overshadowing to Gardens and Shared Space – images showing the change in shadows cast by proposed / existing buildings
  • Glazing % – the level of Glazing on facades / orientations – can be required by Planners
  • Vertical Sky Component – the illuminance ratio at a reference point based on the amount of visible sky – can be required by Planners)
  • Daylight Distribution / No Sky Line – identifies which parts of a room the sky can be seen directly – can be required by Planners)
  • Glare – where there is a potential for ‘dazzle’ occurring when sunlight is reflected from a glazed facade leading to issues for motorist or pedestrians – can be required by Planners)

IES Consulting have the experience to help investigate and interpret the impact on your building design by undertaking the tests summarised above. IES work with you from the concept stage to ensure that building form is well considered and to identify potential problems quickly and help test possible design solutions to reduce planning risks and help avoid the potential for related neighbourly disputes.

In January 2016, the IES team, alongside special guest speaker Jean Carriere of Trailloop, hosted another instalment of our popular IES Faculty BIM webinar series. The event provided an update on our BIM4Analysis strategy and interoperability development work. Based on participant feedback from the event, we compiled the following list of FAQs which have been answered by our experts. You […]

One of the greatest challenges that our societies have ever faced is how to drive energy efficiency at the building, district and city level. Sustainable Places is an International Conference held each year across Europe to gather scientists, researchers, and engineers, from both academia and industry to discuss the latest state-of-the-art advances in this area.

Energy vs Cost Modelling

Posted : June 20, 2016 by Mark Gifford

I recently conducted an energy survey at a new healthcare facility and a couple of headline numbers jumped out which I thought could do with some further investigation and validation. So the focus of this Post is specifically around the application of Energy vs Cost Modelling within the Building Performance Analysis industry. So here are […]

Ever wondered what a Technical Analyst does? Well wonder no more! For this blog post we went behind the scenes to meet with Birthe Klebow, a member of our Software Development team to find out more about her role, what she loves about it and what advice she would give to other women entering a […]

Daniel Coakley presented at the recent CIBSE Symposium on “Integration for whole life building performance.” His session looked at the “Development of calibrated operational models of existing buildings for real-time decision support and performance optimisation.” Building simulation tools are commonly used in design for performance appraisal and optimisation. However, numerous studies have found that actual […]

In a testament to the talent and high level of expertise of our people, Consulting-Specifying Engineer (CSE) magazine, for the 5th time, have selected an IES member of staff to receive a prestigious 40 under 40 award. This year’s winner is Colin Rees, Consultancy Manager at IES. The award is given to 40 non-residential building […]

All Energy: All Wrapped Up

Posted : May 17, 2016 by Edwina

As the doors to All Energy closed the other week, so did the end of a busy week for IES. Our R&D division presented on five different European funded projects we’re currently involved in: EINSTEIN & Energy in Time: Making real-time operational control of buildings a reality with 3D simulation Catherine Conaghan, Senior Project Manager, […]

Last Week Daniel Coakley of IES spoke on the topic of “Modelling Natural ventilation in the IESVE: Case studies & Research Outlook” at a half day seminar, organised by Cork Institute of Technology (CIT), for researchers, designers, engineers & architects. This CIT Technical Seminar: Ventilative Cooling & Overheating Risk was organised in collaboration with IEA-EBC […]
