Selecting energy-efficient plant is just the first step in efficiency, how it’s controlled through its life is just as important. *Kevin Stones illustrates this
principle with reference to cascade heating systems

Pollution in the working area depends on the air flow concept as well as the type, arrangement and magnitude of the heat loads; beyond that, it depends on the type and
arrangement of the air outlets. For example, pollution levels up to 100% with mixed ventilation can be reduced to below 10% using alternative air flow patterns.

Achieving optimum performance in heat networks requires close attention to system design alongside integration and control of diverse heating technologies. Geoff Lord,
Technical Sales Manager at Hoval UK, explains

The selection of ventilation and air conditioning systems for production halls with extensive heating loads has always been a challenging part of planning and design.
Our ultimate guide will highlight some of the major differences, and help you find the best solution for your project. The first...

Hardly any new building can do without controlled ventilation. Due to new buildings being so well insulated for energy reasons, there is no spontaneous exchange of
air. So what about old buildings? Does it make sense for them too?

District heating is set to play a key role in the UK’s carbon reduction strategy and is also central to the European heating and cooling plan. In this blog we answer
Heat Network FAQ's, and discuss the importance of District Heating.

It's a common misconception that mildew only occurs in old buildings. Where there is moisture, the furry fungus can sprout. Are the inhabitants to blame for not airing
out the building enough? Architects who plan incorrectly? Or negligent contractors?

Hotels, hospitals and nursing homes consume huge amounts of energy. Programmes are used to keep consumption under control, and energy efficiency is the top priority
when it comes to investment decisions.

Heat pumps are more in demand than ever before: they supply heat efficiently and are environmentally friendly. Nevertheless, the more popular they become, the more
quickly myths spread concerning their characteristics and operation. In this article, we’re going to straighten things up.

Factories, warehouses and other ‘shed’ type buildings provide special challenges for HVAC systems. Eduard Kovac explains how decentralised ventilation units can meet
many of these challenges

When the time comes to replace heating equipment, or to install a completely new system, there are a number of factors that will contribute to a maximum return on that
investment. Ian Dagley discusses the most important considerations

There is growing concern in the UK about the levels of air pollution in our cities and the possible implications for health, but what many people don’t realise is that
the pollution inside our buildings can be as much as 100% worse than outside air. How can we fix this?

Confirmation from the Chancellor that the RHI will be retained means that building operators can continue to maximise their benefits from biomass heating – as long as
they address some important criteria.

As district heating systems/heat networks gain in popularity it’s important to ensure they deliver optimum performance. This will only be achieved through close
attention to every aspect of the system design

We spend more than 80% of our time indoors, and take 15,000-20,000 breaths per day. So it may come as a surprise to you that the pollution indoors could
be up to 100 times worse than outdoor pollution. The air in our homes, offices and schools has a huge impact on our health, so it is...

Climate technology in a warehouse has to be able to provide supply air and dissipate heat loads and/or pollutant loads. In principle, air flows can be transferred in
two ways: either mechanically by ventilation and air-conditioning units or without machines by means of free (natural) ventilation using pressure differences. These
pressure differences are created inside the warehouse by heat released during the production processes (negative pressure) and outside by wind pressure.

The investor's and developer's goal at the beginning of every project is quite obvious: To build or renovate the building using modern technologies. Execution costs
often play a huge role in the decision-making process. However, this innocent idea does not always lead to the expected savings. One such project is the redevelopment
of the historic building in the center of Prague.

An improper micro climate with little air filtration can encourage the growth of a huge amount of contaminants, including the Legionella group. Read our tips on how to
avoid these contaminants in your heating system.

Access to information, priority setting and proper communication between industries are of key importance for the success of designing systems. We currently have files
at our disposal, which can be used in 3D modeling of these buildings and building systems. This will enhance the design process and ensure a constant flow of
information between all the participants of the process. And that is what BIM (Building Information Modeling) is all about.
