Hoch Bau's approach to sustainable design;
We realise that projects require varying levels of sustainability and we work collaboratively with our clients and consultants to determine which features present the greatest value for money for each building. We promote sustainability in both our Practice and our buildings from the first conceptual sketches through to the completion of a project. This allows us to seamlessly integrate environmentally-conscious features and also to make fundamental decisions regarding sustainability early in the design process which saves both time and money.

We create inspiring and beautiful buildings of elegant simplicity, which are:

?design based on simple and fundamental principles that make the architecture to do all the hard work in saving energy and reducing environmental impact
?sustainability integrated into design rather than as added eco-cliches

We achieve dramatic reductions in energy consumption and carbon emissions by optimising the building shape, section and orientation to maximise the comfort, delight and benefit of daylight, solar gain and natural ventilation, whilst avoiding overheating. This is underpinned by high levels of insulation, high performance windows, excellent airtightness, elimination of thermal bridging, and carefully integrated services with simple intuitive controls.

At early design stages we are able to provide full sustainable modelling and building thermal analysis service. With BIM, we can model various criteria, such as solar, thermal, shading, lighting and airflow, to determine how they will affect building performance. A building’s total energy use and associated carbon footprint can be determined and reduced.

We minimise wider environmental impact and create healthy internal environments, by using natural materials, with low embodied energy, that are renewable, recycled, and manufactured in non-polluting processes, such as UK grown timber, recycled newspaper insulation, organic paints and stains, cork, rubber and linoleum.

By integrating sustainability and avoiding unnecessary complexity in design and detailing, we create uplifting and beautiful sustainable buildings, that are practical, robust and affordable.

Code for Sustainable Homes

The Code for Sustainable Homes is an environmental assessment method for rating and certifying the performance of new homes in England, Wales and Northern Ireland. It is a national standard for use in the design and construction of new homes with a view to encouraging continuous improvement in sustainable home building.
The code works by awarding new homes a rating from Level 1 to Level 6, based on their performance against 9 sustainability criteria which are combined to assess the overall environmental impact. Level 1 is entry level above building regulations, and Level six is the highest, reflecting exemplary developments in terms of sustainability.
The sustainability criteria by which new homes are measured are:
?Energy and CO2 Emissions – Operational Energy and resulting emissions of carbon dioxide to the atmosphere (different minimum standards that must be met at each level of the Code)
?Water – Internal and external water saving measures specified (minimum standards that must be met at each level of the Code).
?Materials – The sourcing and environmental impact of materials used to build the home (minimum standards present).
?Surface Water Run-off – Management of surface water run-off from the development and flood risk (minimum standards present).
?Waste – Storage for recyclable waste and compost, and care taken to reduce, reuse and recycle construction materials (minimum standards present).
?Pollution – The use of insulation materials and heating systems that do not add to global warming.
?Health and Well-Being – Provision of good daylight quality, sound insulation, private space, accessibility, and adaptability(minimum standards present for Code Level 6 only).
?Management – A Home User Guide, designing in security, and reducing the impact of construction.
?Ecology – Protection and enhancement of the ecology of the area and efficient use of building land

Hoch Bau Architecture are experienced in producing buildings to the Code


The term passive house (Passivhaus in German) refers to a rigorous, voluntary, standard for energy efficiency in a building, reducing its ecological footprint. It results in ultra-low energy buildings that require little energy for space heating or cooling.

Passive design is not an attachment or supplement to architectural design, but a design process that is integrated with architectural design. Although it is mostly applied to new buildings, it has also been used for refurbishments.
