Hybrid Variable Refrigerant Flow

This seminar covers the basic principles of air-conditioning and explains how a modern air-conditioning system works, how it solves the problems of the past and how it complies and satisfies the latest regulations.

In 2020, the UK government set out a roadmap for the country to achieve net zero greenhouse gas emissions by 2050. One vital step on this road is the importance of wellbeing in our homes, improving indoor air quality and tackling overheating.Updates to the Building Regulations, and in particular Part F (ventilation) were announced to further its net zero agenda. It also introduced a new Part O which deals with the issue of overheating in modern dwellings. This presentation looks at the main areas of the updated regulations that impact the design, installation and operation of residential ventilation systems.

Seminar covers technological trends and legislative and market forces and discusses benefits of new mixed mode systems that combine natural ventilation and air conditioning and the greater use of heat pump technology for space and hot water heating, particularly when linked to ground source cooling/heating.

Legislation on carbon reduction, mitigation of climate change and use of renewable energy sources is having a huge influence on most business sectors. Not least construction and building services engineers. The UK is not alone in its growing concern about the impact of domestic and commercial buildings on the environment. The legislation which is being implemented here has its source in worldwide agreements, in some cases in international treaties which were signed over a decade ago. In this Guide we will be looking at some of the key drivers behind UK legislation, and how these are being implemented in this country.

In the commercial sector, 55% of energy used in buildings is for heating, according to the Department for Energy &amp, Climate Change (DECC). Many legislative drivers are forcing building operators and owners to find new ways to reduce their energy consumption, so finding energy efficient heating technologies is an important issue. There are also strong arguments for reducing our use of primary fuels by switching to more energy efficient and renewable sources of heat for commercial buildings. Finding energy efficient and renewable solutions for heating commercial buildings can be a challenge – heat pumps offer a new approach to heating commercial buildings, based on well-established and reliable technology which offers the added benefit of being officially recognised as ‘renewable’.

The changing face of construction in the 21st century demands that designers, specifiers and suppliers work as teams to create better buildings for their occupants and the environment. This seminar is designed to enhance knowledge and awareness of the key issues facing industry today relating to the use of building controls and their effect on efficiency levels in various applications.

Reducing the environmental impacts of the built environment has become a priority. As the built environment is a significant contributor to man-made emissions, it is imperative that we better understand the main causes of these emissions. Buildings generate emissions throughout their lifetime, from design, build, use and end-of-life disposal. While operational emissions from the built environment are significant, they do not account for the emissions generated through the construction process, the manufacture, transportation, and installation of its component parts or, for the disposal of these at the end of the building’s useful life. These emissions are known as Embodied Carbon.

While Global Warming Potential (GWP) provides a standard single number for assessing a refrigerant’s impact on the environment, it does not tell the whole story. Unfortunately, GWP is currently being used by environmental lobbying groups, Government and opposition parties to justify moves to ban HFC refrigerants completely. There are numerous technologies available today which can help building owners and managers provide comfortable and productive indoor environments while taking a low-energy approach. Products which combine heating and cooling, or hot water production with air conditioning can be used to ensure that energy waste is minimised.

The seminar looks at what the Enhanced Capital Allowance Scheme is, its history and qualifying technologies. Other points covered include ECA criteria, claiming ECA's and a frequently asked question and answer section plus useful websites and other points of further reference. AIM - to provide a better understanding of the ECA Scheme and how to claim ECA's.

Ground source heat pumps are proving an increasingly popular sustainable choice for commercial buildings to deal with both heating and cooling requirements. One of the advantages of the system is that they are based on well-known and straightforward technologies. Ground source heat pumps can be applied to a variety of applications and while some preparation is required to ensure smooth and efficient operation, they can provide many years of reliable and energy efficient service.

Seminar and accompanying guide gives an update on BREEAM, the scheme for the assessment and certification of sustainable buildings. The scheme has now been broadened to cover all types of areas.

This Mitsubishi Electric guide &amp, presentation provides an insight into the net zero target proposed by government, which has generated a range of new and proposed legislation on energy use and adoption of low carbon technologies across industries. This provides an opportunity for new approaches to building design and operation to flourish, and to encourage building owners to adopt low carbon building services technologies such as commercial renewable heating.
