Domestic Energy Assessors Help Homeowners Show the Energy Efficiency of Their Homes When Selling

There is a new breed of professionals who you will get to know about now when you start out to sell your home. They are called Domestic Energy Assessors and are out now in England and Wales performing a brand new service.

The role of the Domestic Energy Assessor is to produce Energy Performance Certificates for inclusion in Home Information Packs. If this is complete news to you then just think of these as being certificates, like those you see on new fridges, which will provide A-G ratings on the energy efficiency of a home, plus advice on how to make further energy savings.

Energy Assessors will use their in-depth knowledge and practical understanding of the thermal performance of your home to judge on the thermal energy efficiency of properties.

This requirement has been introduced by the UK government working on the theory that these assessments of the the capability of all buildings about to be sold will encourage us all to be energy efficient. This will be good for the nation as it will be thoroughly green. It will the idea is, help avoid the need for the energy whether renewable or not.

This type of certificate is required whenever the building is constructed, sold or rented.

In the short term home owners directly, and home buyers indirectly, will need to pay for these Energy Performance Certificates (EPC) and in order to possibly carry out work to improve poorly insulated properties, they will need to pay for general advice to clients on energy efficiency measures.

This is all very good in principle, but the UK government has chosen exactly the wrong time to do this. The credit crunch is hitting the house sales market hard, it is already very difficult to sell properties, and the value of most of them is falling.

The staff that produce Energy Performance Certificates are very experienced in construction technology, building condition surveying and domestic energy assessment and are Degree qualified professionals. They do not come cheap!

Now we do accept that most assessors will not simply stop at inspecting your property, they should also take the time to explain exactly what they are inspecting, how they are going to go about it and gladly answer any questions that you may have. But, most sellers are going to deeply object to being forced by the state to take on this additional burden of cost.

The energy assessor takes measurements to analyse the cost of heating, water and lighting for a house and makes recommendations to improve the energy performance of the house. To me it looks like you the government may think that an assessment is a quick hour in the property and thats it. I doubt they have fully considered the travel time to and from the houses to be assessed, time taken to assess, time to prepare and check the report, input the data, produce the certificate and then charge a fee which includes the professionals insurance, accountant fees, advertising and many other costs – the list goes on and on, after all they will have to make a living like everyone else.

How Cooling Systems Can Improve Your Energy Efficiency

The business case for energy efficiency is a powerful one. At the end of 2010, the Carbon Trust reported that the average return on investment of energy-efficiency projects carried out in commercial premises is 48%. Increasingly, it is becoming clear that to invest in sustainability is to save money.

But while the UK government is supporting carbon reduction by introducing grants and green initiatives, these have done little more than skew people’s perception of what represents an energy saving. With heavy focus applied to insulation and heating, cooling strategies have been left rather more out in the cold.

The hot topic

The government’s Renewable Heat Incentive (RHI) was announced in March 2011 to drastically alter the way heat is generated and used in buildings and homes. Britain’s largest energy users are required by the CRC Energy Efficiency Scheme to start lowering carbon emissions so will naturally be enticed by such offers. But incentives like the RHI fail to acknowledge that when a commercial building is designed, the crowds of people and electrical appliances that then occupy it are not taken into account.

Human bodies and devices such as computers, printers, coffee makers, toasters and refrigerators generate an exceptional amount of heat and cause room temperatures to dramatically increase. So, instead of heating, most commercial buildings need to bring temperatures down in order to maintain a comfortable environment and maintain staff productivity.

Office cooling, namely air conditioning, represents a huge energy burden, and can increase a building’s emissions by 100%, according to Carbon Trust research. So, to use it on a daily basis yet take a grant to invest in heating and insulation is a notion most people would surely see as perverse.

The reality of air conditioning is that, despite its widespread use, the energy it consumes often goes to waste. Realistically, without tackling this problem it is unlikely than any commercial building will be able to create a truly energy-efficient environment, no matter how much government grant money it is awarded.

Here comes the sun

As we all know, when the sun comes out in the UK, it is met with something resembling blind panic. Whether in the heights of summer or the depths of winter, sunshine causes heat to build up through unprotected glass windows. These windows then get thrown open to create a through draft, or in colder months, blinds will be snapped shut to block out the sun’s glare, meaning that lights have to be switched on. Either way, this behaviour ends up negating the effect of air conditioning, causing wildly fluctuating internal temperatures and eating up a large, unnecessary supply of heat and energy.

Such widespread and basic energy wastage should not be allowed to continue. Maintaining stable internal temperatures requires more than efficient heating and insulation; businesses need a cooling solution that minimises air conditioning, allows natural light to enter the building and helps to block out heat, rather than trap it within the building. One of the most simple and most cost-effective solutions that can deliver all of these benefits is one you may not have heard of: solar-control window film.

By rejecting up to 82% of solar energy, window film can reduce internal temperatures by up to ten degrees. This stops air conditioning units from being maxed out during sunny spells, meaning that internal temperatures are kept stable and extreme peaks in energy usage are reduced.

Cooling systems can therefore be run more efficiently and inexpensively, reducing a building’s cooling load by 30%, or roughly 5% of the energy bill. If window film were taken into consideration during the design stages of a new building, savings would be greater still as businesses would reduce cooling requirements from the outset; using smaller, cheaper air conditioning units that are easier to install and maintain. In plain English, this could mean thousands of pounds in savings to many UK firms.

Love in a cold climate

With budgets being squeezed and such significant carbon reductions to be made, the heat is on for UK businesses to find meaningful ways to lower emissions. It is the responsibility of our government to steer them in the right direction. Improved insulation and heating is, without doubt, an effective means of preventing energy waste, but without considering the likely effects of over-heating, businesses are in danger of missing the bigger picture.

While most UK businesses will currently look to insulation as their first port of call for energy savings, more vocal support for solutions such as window film by government schemes and incentives, would show these companies that such measures are just the tip of the iceberg.
