Most buildings, whether residential, commercial, or industrial, consume a significant amount of energy over their lifetime, whether for lighting, heating, ventilation, or plugged-in devices. Buildings consume approximately 40% of global energy, 25% of global water, 40% of global resources, and emit approximately one-third of global greenhouse gases.
The energy required to power these structures has risen precipitously in recent decades, putting an increasing strain on national power grids. This has increased the pressure to generate power by burning fossil fuels, contributing to the current climate change. This lethal cause and effect has compelled many engineers and policymakers to consider how we can reduce energy consumption in the buildings we build.
What is a Zero-Energy Building?
A zero-energy building (ZEB) is one in which the total energy used over the course of a year is equal to the amount of renewable energy produced - in other words, it produces enough energy to meet its own annual requirements. This means it does not require energy from the power grid, lowering greenhouse gas emissions. In addition to mortgage or bank repayments, utility bills are one of the most expensive running costs for these homes, offices, and manufacturing plants. So there are financial as well as environmental reasons for having ZEBs.
The scope and approach of these terms vary, but the fundamental goal of reducing energy usage, improving building energy performance, and lowering greenhouse gas emissions applies to all definitions.
Components of A Zero-Energy Building:
A ZEB has two main components: reducing the building's energy consumption and producing renewable energy for on-site use. The first key element (lowering the total amount of energy used in a building) can be achieved through the use of energy-efficient lighting systems, insulation, better water management, improved ventilation systems, and smart meters. Even changing occupant behavior can have an impact on a building's energy efficiency. The second component (on-site generation of renewable energy) could include installing solar panels, small wind turbines, or micro combined heat and power systems to meet a building's electricity, heating, or cooling needs. Any excess energy generated by the building can be transferred to the national grid, allowing the building's owners to profit from their own thriftiness.
Zero energy cities are an engineered extension of zero energy buildings. As more buildings become energy self-sufficient, communities and cities may become zero energy. This means that the total energy consumed by a city's infrastructure will be equal to the amount of renewable energy generated.
Engineering solutions that create zero-energy buildings, whether residential, commercial, or industrial, are the first steps toward achieving zero energy cities - a transition that will be critical in slowing rampant climate change and that we must now accelerate.

Theconstruction industryhas long been challenged by a number of inefficiencies. As countries across the world look to stimulate their economies into recovery, investment in infrastructure and construction projects is at the forefront for many—meaning now is the time for construction companies to face and resolve their inefficiencies.
In an earlier blog I looked atkey trends in the industry for 2021and noted that increasing productivity is still one of the major hurdles that the industry needs to overcome. However while there is no one-size-fits all to resolving this, there are some general themes that can be adopted by all who are ready to transition to a more dynamic, agile and profitable construction company which is centered around the adoption of best practices.

Building Information Modeling (BIM) is revolutionizing the architecture, engineering, and construction (AEC) industry worldwide. For many public sector and major projects, BIM has become the required method of working. Yet, despite the increasing acceptance and use of BIM, there are still some barriers to its adoption.

While an important milestone, the remainder of Phase 2B connecting Birmingham to Leeds awaits similar backing. Delivery programmes can often become constrained by timescales associated with land acquisition, procurement and site mobilisation at the start of a project.
As this legislation makes its way through Parliament, continuous and prompt delivery of the integrated route must be supported. This will enable efficiencies and benefits to be realised during both delivery and operation phases of the complete HS2 route, as well as Northern Powerhouse Rail (NPR). HS2 will provide 50% of the infrastructure for NPR; a project designed to transform the rail network in the north of England.
Encouragingly, the Queen’s Speech recognised that improving existing processes can be equally conductive to positive transformation. The Planning Bill will modernise our current systems with simpler frameworks, enabling those on the ground to deliver environmental and commercial opportunities more promptly. This will also support delivery of the UK’s ambitious net zero target. While efficiencies are encouraging, the importance of public consultation, as many major infrastructure projects currently undertake from conception to completion, should not be forgotten.
