Case Studies: Reduce Energy Consumption of your Buildings’ HVAC

Category: ,

The presentation looks at how leading organisations have significantly reduced the energy consumption of their existing HVAC equipment, by fitting EC fans and controls as well as improving the system design. The main case study will look at how a major UK airport achieved energy savings of 73%, additional case studies look at savings achieved for data centres and commercial buildings.

Details will be given on how the projects were managed and completed, and look at not only the energy savings but also the additional benefits offered to building managers such as improved control and monitoring, reduced noise, reduced maintenance, built in redundancy and extended product life.

Attendees will:
- Understand the important part HVAC equipment and the fans & controls used plays in delivering an energy efficient building, HVAC is one of the
main contributors to energy bills for most commercial buildings.

- Understand how upgrading your buildings' existing HVAC equipment can be a relatively simple task and offer excellent energy savings and ROI.

- Case studies demonstrate how leading companies are already benefiting from fitting high efficiency EC fans in their buildings HVAC equipment,
achieving energy savings of up to 73%.

- Learn how improvements to system design can deliver additional benefits including reduced noise, improved control, accurate power measurement and
predictive maintenance.

Utilising your Building Assets to Improve Indoor Climate and Reduce Energy Consumption

Category: ,

David will explain the benefits Skanska and their client AMF Fastigheter have achieved by utilising the thermal storage capabilities and natural assets of their properties. These principles are based on theoretical research conducted at the KTH Royal Institute of Technology in Stockholm and are brought to life, by Ecopilot, through the use of modern technology.

David and Viktor will discuss the opportunity to achieve carbon reduction targets where “low hanging fruit” options may have been exhausted, and share their journey as well as the road ahead.


14:00 - 14:30

A Meter of Life and Death

Category: , ,

Metering is the bread and butter of energy management, without it, we cannot even begin to understand what, when and how much we use; to manage energy, you need to understand your usage, and to do this, you must have sight of consumption. The scale of the task, in delivering accurate metering to domestic and commercial users, is the sheer diversity of meters, from old turbine and bellows type gas meters, to the latest digital Smart ones.

SMART Meters – Anything but! – The problems with Smart metering:

  1. Inaccurate (Less than 30% are accurate, with some as much as 400% over reporting).
  2. Cannot be fitted on sites with common supplies such as blocks of flats.
  3. Restrict competition by dissuading users to change suppliers due to incompatible technology between users.

Data – With accurate data, patterns can be identified, to show how much, when, and why energy is used, which allows the energy manager to predict future usage and identify potential efficiency savings. But this only works if the data is good and as energy managers, we do not deal with guess work – our mantra is facts, not opinions.

“Mind the Gap” – The difference in performance between design and the building “in-use”


We have the ability to design good buildings and the knowledge to operate them in an effective and efficient manner – so why doesn’t it happen?

As we drive the performance of our building stock, it is becoming clear that one of the key challenges we must address is narrowing the gap between design and actual performance. The industry needs support to ensure they understand how the building will perform in operation. If we don’t, the gap in performance can be as big as 200-450% greater than predicted. With project costs squeezed and ‘value engineered’, all too often performance suffers.

This expert panel will discuss the issues such as:
• Designing for compliance;
• Commissioning and soft landings;
• Benchmarks and real performance.

Case Study: Operational Energy Reduction through Data Analysis & Virtual Benchmarking


In this session, IES will explore the use of digital building performance models during building operation to optimise performance and reduce “in use” energy consumption. To satisfy regulatory requirements (e.g. Part L/Section 6) a digital model is created during the design stage for practically all new commercial buildings, but often these regulatory compliance models under predict energy consumption by a large margin, known as “the Performance Gap”.

With additional effort, these compliance models can be enhanced by combining utility and BMS data with the 3D virtual model and undertaking a calibration exercise. This enhanced digital asset provides a much more realistic representation of building performance and energy consumption and can therefore play a valuable role in improving operation of the building and identifying opportunities for energy savings. New Parametric and Optimisation techniques are also playing a key role in reducing the time it takes to undertake model calibration.

During 2016, Barts Health NHS Trust – the largest NHS Trust in the UK - undertook an innovative project with IES to perform enhanced Energy Modelling and Building Management System (BMS) Data Analysis services for the Alex Wing, Dental Teaching Hospital within The Royal London Hospital.

The project aimed to take advantage of the existing BMS and extensive sub-metering infrastructure and utilised the latest advances in building performance modelling to deliver innovation in how the Trust approaches assessment of proposed Energy Conservation Measures (ECMs).

Through a combination of building data and advanced computer modelling, IES succeeded in creating a virtual benchmark of the building which comfortably meets the calibration thresholds for ASHRAE Guideline 14. The calibrated model was used to identify operational issues and assess potential Energy Improvement Strategies, with possible energy demand reductions of 22.5% for Gas and 30% for Electricity demonstrated.
