Maximise daylight potential and meet planning requirements

Whether you're a planning consultant, developer, project team, contractor, or resident, you need reliable evidence for planning submissions delivered with accuracy and efficiency. Use our expert daylight and overshadowing analysis to ensure your project meets BRE 209 2022, BREEAM, or DfE Output Specification Annex 2E.

With 40+ years of combined expertise, we use comprehensive IESVE software to produce detailed simulations and calculations. These can be used to optimise building designs and solve potential planning challenges.

Key services for your project
• Target Illuminance Levels to demonstrate internal daylight
• Overshadowing Analysis to assess the impact on main amenity spaces
• Vertical Sky Calculations (VSC) to demonstrate the impact on neighbouring properties
• Climate-Based Daylight Modelling for Schools Output Specification compliance
• Average Daylight Factors (ADF) Calculations provide BREEAM evidence

Sectors covered
🏡 Residential | 🏫 Schools | 🏢 Offices | 🏛 Community Buildings

Get the right advice at the right time to navigate planning, optimise daylight, and enhance building performance.

Meet the Team

Clare joined HDSgreentech in 2017, bringing transferable skills from previous employment that provided an alternative perspective, helping to balance the team.
In 2020, she completed a Level 3 BTEC Diploma in ‘Construction and the Built Environment’ at Southampton City College, achieving a Distinction/Merit. Clare followed this up by attending an ‘Introduction to Zero Carbon Buildings’ at the University of West England.
Clare reflects on the past eight years: “Through my work and the training courses I've undertaken at HDSgreentech, I've learned to deliver sustainable, holistic designs, considering site characteristics, built form, and renewable strategies. I've also developed our Daylight Assessments, working closely with local planners to provide support and guidance to achieve recommendations. I'm always happy to go above and beyond for our clients."

HDSgreentech celebrates our 10th Anniversary 🌿

As we start 2025 we’re reflecting on not just last year but the past 10!

Since establishing ourselves as highly reputable and reliable specialists in building sustainability, we’ve been involved in so many exciting projects.

From ancient to modern, we’ve worked on the building that houses the Mary Rose in Portsmouth to the Facebook HQ in London.

Large and small projects (and everything in between) have been covered, from universities and leisure centres to private residences.

Solutions have been found to improve comfort levels in buildings both old and new.

Delivering sustainable building solutions for everyone, lessening environmental impact and waste energy, is at the heart of what we do and we’re proud to have been improving buildings for all for 10 years.

If you have a project old or new, big or small, that needs a building sustainable solution, get in touch.

HDSgreentech donated play parachutes and play silk scarfs for an employees daughter to take on her 12 day trip with Brock2Kenya to work on three projects for impoverished children in Nukuru outside Nairobi.

She visited Melon Mission School, Little Kings Nursery and Silver Bells Welfare Centre for Orphaned Children donating a parachute and scarfs to each, allowing them to enjoy the activity long after her visit.
