Baxi’s Commercial Sales and Specification Director Rob Erwood discusses some of the approaches to tackling the net zero challenge.

From commercial spaces, public buildings, and more, the built environment is responsible for approximately 25% of the UK’s greenhouse gas emissions. A figure which reaches 38% when accounting for total global carbon emissions as a whole. In the face of growing concerns surrounding climate change; individuals, companies, and governing bodies alike have made commitments to half global emissions by the end of the decade, eliminating them in their entirety by 2050.

Artificial intelligence, incorporating Internet of Things (IoT) solutions, is key to enabling building owners and managers to improve performance as well as lowering energy use, costs and carbon emissions, writes Adalbert Neumann, Global Product Group Manager Building & Home Automation Solutions, Smart Buildings Division, ABB Electrification.

David Harris, Managing Director, Premier Modular, considers how close we are to achieving carbon efficiency, whether we’re on track for net zero targets, and how to take that critical next step to achieve carbon-efficient buildings.

High temperatures are increasingly common in the UK with four of the five hottest summers on record having happened since 2003. Tim Mitchell, Sales Director at Klima-Therm, examines the likelihood of future heatwaves and discusses the implications for the cooling industry.

Vidal Bharath, Chief Commercial Officer at Bramble Energy, says much of the ability of the UK to successfully meet its 2050 net zero target will hinge on the success of the construction sector’s decarbonisation strategy.

Innovations to decarbonize buildings have brought the goal of Net Zero within reach. To achieve it, industry and government must work together to implement them. Eric van Oossanen of Trane looks at the issues. 

Elitsa Yakimov, Marketing Manager at Armacell UK, discusses the latest IPCC report amongst others, and comes to the sobering conclusion that it will be impossible for the UK to meet its 2050 Net Zero target without fundamental changes to the ways we build and heat our buildings.

Alistair Bell, Director at ThermoSphere, discusses the mood in construction, and the industry’s opportunity for growth.

“With very little sign that the cost pressures are easing, what is the impact of this uncertainty?”, asks Anthony Ainsworth, Chief Operating Officer at npower Business Solutions.

Peter Sayce, Product and Commercial Development Officer at Bramble Energy says the industry must go further to make sure that any new infrastructure is built in the most efficient way possible, and existing stock is improved and repurposed where possible.  

With 80% of the UK’s 2050 building stock having already been built, there remains a major priority to decarbonise existing stock to meet climate targets. Stephen Flood looks at how. 

What are the challenges and opportunities for organisations as they tackle heat decarbonisation amid the continued energy crisis? Rob Erwood of Baxi Commercial solutions has answers.

With the UK Government setting ambitious targets to achieve decarbonisation and net zero emissions by 2050, Alex Ashton, Environmental and Sustainability Manager from Polypipe Building Services, explains how manufacturers have a role to play in a low carbon.

To achieve a reduction in the UK’s carbon emissions, we need to look at BOTH the means of heating, cooling and airing a building, and our sources of supply says Roy Jones, Technical Director at Gilberts Blackpool.

The energy efficiency of buildings and products has improved dramatically over the past 30 years, but to protect the global environment we must also crack the more complex challenge of reducing ‘embodied carbon’, according to the Building Engineering Services Association (BESA).

Giving building managers the power to make informed, data-driven decisions that reduce CO₂ emissions, optimise energy efficiency and create a more sustainable world, says  Dr. Thorsten Müller, Head of Global Product Group: Building and Home Automation Solutions at ABB

Post-pandemic life is still uncertain. Priorities have changed and targets shifted. New and flexible forms of work (“New Work”) as well as the growing importance of employee satisfaction present companies with new challenges. Buildings nowadays are also measured by whether they provide a productivity-enhancing and inspiring environment. Leighton James, Product & Marketing Director, TRILUX and Alex Klein, Director of Sales, wtec tells us more.

80% of the buildings that we’ll use in 2050 – the UK’s target for achieving net-zero – have already been built. Reducing the energy requirement of these buildings is a key step in the transition to zero carbon. Caitriona Jordan, head of retrofit programmes at Construction Scotland Innovation Centre (CSIC), looks at how. 

This year, England, Scotland and Wales are taking significant steps towards achieving net zero carbon emissions with the introduction of tougher building energy efficiency standards. In addition to these efforts to cut the operational impact from buildings, there is also growing pressure to address their embodied impact. These are the emissions from the processes needed to construct, maintain and deal with a building at end of life. As a result, project teams are being increasingly asked to consider these factors as part of the design and specification of projects. 

A single unifying body can concentrate all efforts from all sectors of the building products & services industry in achieving clear and concise information exchange in drive to net zero carbon

I was interested to read about the report from Infrastructure Management at Sheffield Hallam University stating that solar thermal panels cost around £3500 to install [MBS February 2012, page 8].

Immediately available from Shorts Environmental, which specialises in the design, supply and fitting of low-carbon building-services products, is a new biomass package. According to Mike Wheeler, national sales manager with Shorts, a biomass system is the runaway winner in any contest for lowest running costs. He is convinced that end users, architects and specifiers will be looking beyond the initial installation costs to the quite substantial operating gains achieved in lifetime savings.

Dimplex is helping installers get to grips with a new installation standard for heat pumps that came into effect from February 2012. Chris Davis, business-development director with Dimplex Renewables, says, ‘We believe MIS 3005 is a positive move for the industry and will help heat-pump systems deliver the consistently high performance that’s needed to encourage the uptake of renewable heating in the UK.’

London Data Exchange, which provides network-independent colocation solutions and data centres, has chosen Airedale International Air Conditioning as its cooling partner. Airedale has designed a low-energy, resilient solution for LEeX1, a purpose-built £5 million 2000 m2 carbon-neutral data centre due to open in April 2012 and close to the south end of the M1.

Existing buildings can benefit from a considered approach to substantially improve their energy efficiency. David Lewis outlines four simple steps to achieving energy efficiency and the notable savings that can be made in the process.

The low water temperatures that characterise heating systems using renewable energy do not preclude the use of radiators, says Chris Edwards, marketing director with radiator manufacturer Purmo. He says, ‘Even in countries with harsh Winters such as Sweden, radiators are accepted as an integral part of a modern, efficient and green heating system. Our low-temperature-technology products prove that radiator-based heating system provide a quicker a more consistent heat distribution in many settings.’

AET now offers the Camel Solar high-efficiency evacuated-tube solar thermal collector, which can absorb over 92% of the Sun’s energy that lands on it. This capability is said to make it one of the most efficient solar collectors on the market, with a stagnation temperature of 250°C. Evacuated tubes enable these collectors to work effectively even during the coldest months of Winter.

Lighting is widely recognised as one of the best starting places to reduce energy costs in the built environment. Graham White and Greg Herring outline the key issues to consider.
