Offices account for the highest usage of energy in non-domestic buildings, in the UK, alongside retail premises, accounting for 17% (27,620 GWh/year) of the total non- domestic energy consumption. Surprisingly this puts them ahead of industrial buildings. A whopping 67% of this is accounted for in the consumption for building services, this includes heating, ventilation, cooling, hot water and lighting.

Reducing energy in any building is always going to make sense financially and will often come with the added bonus of increased comfort levels for the occupants. The Carbon Trust ‘estimates that up to 90% of heating, ventilation and air conditioning building control systems are inadequate in some way, costing industry and commerce over £500 million per year in energy costs’. Typically, poor boiler control can add 15-30% to fuel consumption costs in an office building. This is certainly something most organisations would wish to address.

The opportunity to optimise building systems through BeMS (Building energy Management System) exists in most office buildings with a typical potential reduction in consumption of the systems controlled of around 25% leading to a short payback period, usually in less than 12 months. This is done through optimising the performance of systems, assets and in particular the BeMS that control many of the assets leading to considerable savings in terms of energy consumption, asset life and maintenance costs.

For every additional hour of occupation each day, the consumption can increase by as much as 10% in a typical office. Incorrectly set time schedules, setpoints and optimiser can be a large contributor to this additional usage. Maintaining optimum internal environments for staff and building users will improve comfort, which in turn will help boost attentiveness and morale, alongside minimising energy consumption and carbon emissions.

Reducing the heating temperature by 1 degree can reduce energy consumption by as much as 8%

Why Optimised Buildings

 

Minimising energy usage is our business and ‘Optimised Offices’ utilises analytical technology with engineering expertise and process to maximise savings from assets and systems in a single building or across building portfolios.

We wrap all things ‘energy management’ into a single proposition, based upon your needs, providing you with a single supplier that can optimise the efficiency of your buildings and ensure it remains optimised for the long term. We achieve this using a joined-up approach, ensuring you maximise the efficiency of each element and there is no conflict to compromise services between them.

Optimisation

Regardless of whether your facility has previously undertaken extensive energy saving initiatives and you are at an advanced stage of your energy efficiency strategy or if this is the first step, we are confident savings can be made. 

 

We will review the BeMS operation including: time schedules, setpoints and control strategies along with any energy consumption data that will help us identify where energy is wasted. We will also review the physical HVAC plant and identify areas of savings due to assets configured incorrectly, equipment in manual or areas that may require maintenance or repair. All of which will be formed into a strategy agreed with the client and documented to get the estate on track. 

 

Optimised Buildings work with you, providing consultancy, technology and expertise to minimise the wasted energy and ensure your facilities are running with optimum efficiency through minimal capital expenditure and maximum return.
