Energy Statements

A Energy statement is a report demonstrating compliance to local authorities own carbon commitments.

Tips and Tricks

Photovoltaic arrays can only offset electrical power, to maximize the benefit make sure you are only using electricity onsite

Energy Statements

Tips and Tricks

Air tests can be critical in reducing the building carbon footprnt

Why do i need a Energy Statement

Each local authority have their own carbon commitment targets to achieve,
A energy statement for new buildings aids in the local authority's reduction of Co2

How does it work

The energy statement shall demonstrate how the building betters the notional standard building by using a combination of methods, these may entail thermal improvements to green energy

How do i know the reduction required

Typically local authorities have had a 10% reduction target on Co2, however London has increased it targets to 35% reduction. If in doubt always check with planning beforehand

Be Green

Introduce renewable energy to site, be that PV, top tier Split Systems or Ground Source Heat Pumps

Be Lean

Make sure your building fabric is above the minimum requirements in Part L, look to improve on typical glazing factors

Be Clean

Increase your HVAC system above the minimum standards, aim for a air permeability of below 5PA, and use high efficient LED lighting throughout

Energy Statements Explained

The purpose of an Energy Statement

The goal of the statement is to ensure that a new building or development adheres to local and national environmental policies aimed at reducing the carbon emissions and supporting sustainability.

Tips and Tricks

Site Orientation

Think about the site orientation, large glazed windows on a south facing elevation are going to produce solar gains, this in turn increases the HVAC system's load as it works harder to maintain a comfortable temperature

What is the Energy Hierarchy

The energy hierarchy is a calculation based on the minimum requirements under Part L2 building regulations followed on with improvement factors to the building bringing it inline with the local authorities requirements.

These are typically known as Lean, Clean and Green calculations

Lean, Clean and Green

Lean, Clean and Green refers to differencing modeling of the building demonstrating uplifts through increased building fabric, improved HVAC systems and renewable onsite energy

It's not rocket science

Energy statements aren't new, We have caried out many over the years and have never failed to obtain approval. If you have any concerns, call us today and we shall set your mind at ease

What is a Energy Statement

An Energy Statement is a report required by local authorities or regulatory bodies to demonstrate how a proposed development or building complies with energy efficiency and carbon reduction standards.

The goal of the statement is to ensure that a new building or development adheres to local and national environmental policies aimed at reducing the carbon emissions and supporting sustainability.

The Energy Statement shall include the following.

Energy Efficiency: How the building or development minimizes energy consumption through design features, insulation, HVAC systems, and other measures.
Renewable Energy: The inclusion of renewable energy systems, such as solar panels or wind turbines, to reduce the building's carbon footprint.
Carbon Emissions: The estimated carbon emissions of the building, both in construction and operation, and how they compare to the targets set by local authorities or national standards.
Sustainability Measures: Measures to ensure long-term sustainability, such as the use of low-carbon materials or water-saving technologies.
