"18% of UK emissions come from non-domestic buildings..."


At the heart of commerce in the UK is our places of work. These buildings offer a secure, comfortable environment for educating the youth, governing the country and keeping the economy afloat. It stands to reason then that the better our buildings perform, the better we perform and the more productive we are.

The commercial sector represents about 66% of existing building stock, with vast improvements necessary in order to meet EU energy efficiency targets. With 80% of the buildings in 2050 already built, retrofit represents a massive area of potential in achieving the UK's overall emissions targets (80% reduction by 2050). Additionally, with recent incentives offered under the Feed-in Tariff and Renewable Heat Incentive schemes, installation of renewable technologies presents a worthwhile investment with good returns.


Renewable Energy

The buzzword at the moment is solar PV, however this is not the only option for those looking to generate income by installing a renewable energy generator. A host of technologies have been placed on the Feed-in Tariff list, as well as the recent Renewable Heat Incentive list. 

Generous cash-back rates are offered as part of this self-funding scheme, with the highest tariff paid to solar PV installations below 4kW. Technologies that have higher annual hours of operation, such as wind or hydro power, receive a reduced tariff relative to the expected annual energy yield. Thus the payback period of systems across the range of technologies remains relatively constant - typically less than 10 years. 

The key challenge is determining which type of technology is most appropriate for a particular building. Sometimes this will be largely intuitive, however often a feasibility study is required to compare a number of options.

Refurbishment & Retrofit

Sustainable refurbishment must progress hand-in-hand with sustainable development, if the UK is to meet it's emmisions reduction commitments. Indeed the majority of buildings standing today will still be around in 2050, and thus their energy performance must be upgraded to meet the requirements of a low carbon UK. 

Two approaches can be taken to upgrade a given building: replacement of equipment and changes to building fabric. The former approach would apply more to post-1980's buildings, whilst the latter or both approaches would be necessary for earlier buildings. By refurbishing your building you will not only be establishing a platform form which your business can operate going forward, but also comply with upcoming regulations and reduce annual energy bills. Keeping Blue can advise on the most cost effective course of action for office and warehouse refurbishment, as well HVAC equipment and lighting replacement.

HVAC System Advice

Most existing building stock is not designed to cope with the intensive heat gains from current office applications, such as server rooms and VDU rooms which generate excess internal heat gains in both summer and winter. Additionally, much of the equipment installed in the 1980's and 1990's is nearing end of life and requiring replacement. The solution is often retrofitting of energy efficient technologies, and often low carbon technologies can be specified to further reduce bills and generate income.

Whether your equipment is at the stage of de-commissioning, or you simply wish to upgrade your equipment and reduce your energy bills, Keeping Blue can offer professional advice on the best route to take.


Energy Audit - Common Sense Approach

A recent survey has shown that the actual energy performance of buildings, even those which are well designed, can be more than double the design value. This can be attributed to a number of factors, one of which could be poor understanding and inappropriate use of HVAC equipment. 

As offices are often leased rather than owned outright, tenants tend to have a limited understanding on optimal usage of A/C equipment, and layout of desks and furniture. 

For this reason, flexibility is highly desirable for A/C terminal points in rented premises. Partitioning of open plan office space (pictured) can lead to a poor balance of air flow and temperature control in divided areas. This could be due to temperature sensors being wrongly located, or air outlets being unevenly distributed. Ideally, there should be some level of mobility for ceiling ductwork and outlet grilles, however this is usually limited. Additionally, a common sense approach should be taken with temperature sensor positioning, to ensure that accurate measurements are taken and a negative feedback loop is avoided. 

It is important that tenants are educated regarding the optimal layout of the floor space regarding air conditioning. As part of a Keeping Blue Energy Audit, advice would be given to the building manager regarding suitable floor plan layouts, and in turn the tenants should consult the building manager before any alterations are made. A Keeping Blue Energy Audit will aim to bring a building's actual performance in line with it's potential, with minimal capital expenditure.

Take Action - Show your commitment

For many businesses, not knowing where to start is one of the biggest drawbacks to going 'green'. The task of narrowing down a roadmap towards sustainable operations is often blurry, fraught with ill-advertised green schemes and products. Keeping Blue is here to assist with putting an action plan into place, prioritising the lowest cost, highest impact measures first and foremost. With our simple 'cost per cut' comparison methodology, our report will clearly present the most cost-efficient measures to take, the low-hanging fruit so to speak. This will result in the shortest payback period on your investment and ensure that your money is well spent.
