What We Do – Design
Evolved Design can help you at every step from concept to completion or just when you need us. Find our what we do for our clients below.
Evolved Design are Chartered Architectural Technologists who specialise in designing low energy homes. We design using the principles of passivhaus to provide you with an energy efficient, comfortable home to live in.
We design the home you want to live in but also ensure that the technical specifications for structure, heating, ventilation & air tightness provide you with the cost effective home you’ve asked us for.
We suggest that our clients make a wish list of their requirements by cutting out pictures from magazines and collect details of houses and designs they like. As this helps us to establish what type of design of house they would like to live in – planning requirements accepted!
It is also important that they also consider the environment they want to live in. For example; Low energy or Passive House, environmental considerations for rainwater harvesting, solar heating, heat recovery systems, photovoltaic system, and ground or air source heating. As Chartered Architectural Technologists and Certified Passive House Designers we are able to take into account at early design stages, measures required to achieve these levels of comfort & technical assessments.
Once we have designed your ideal home, the next step is to apply for planning permission. This is required for most developments. Local authorities consider all planning applications against a set of adopted policies contained in their Local Plans. These will tell you whether your proposal is likely to be acceptable or not. Evolved Design will check with the Local Planning Authority before submission as there are limiting policies that would prevent your intended use of the property or design.
When this is completed Evolved Design will prepare any necessary detail drawings and plans and complete the planning application forms. Also certificates and any notices, enclose any other relevant information.
Building Regulation Approval
Once planning is granted, we will then apply for Building Regulation Approval. The Building Regulations set out the requirements necessary to ensure a consistent and appropriate standard of health, safety, energy conservation and accessibility is achieved in building work, for both domestic and commercial proposals. They are regulations that are laid down by Parliament and are accompanied by a series of “Approved Documents” which relate to particular aspects of the Regulations.
These Approved Documents range from Structural performance, Part “A” through to Part “P”. The Regulations cover most building works including:
- the erection of new buildings
- conversion and extension of existing buildings
- installation of heating, drainage or sanitary facilities
Furthermore most must be completed in accordance to the information laid down in the regulations.
It is at this stage that we calculate the predicted energy performance of your new home and advise and provide effective recommendations for improving it. We will work with you and advise on the heating and ventilation specifications which provide you with a comfortable, cost effective home to live in.
Is the study of Earth’s surface features. In a broader sense, topography is concerned with local detail in general, including drainage, surrounding building heights, vegetative and human-made features, and even local history and culture.
Topography specifically helps the planning process as it involves the recording of relief or terrain, into a three-dimensional quality of the surface, and the identification of specific landforms. This involves generation of elevation data in electronic form and is including the graphic representation of the landform on a map, including contour lines, relief shading.
SAP Ratings (Standard Assessment Procedure) for Energy Efficiency Ratings for Dwellings is requirement under Part L Building Regulations.
The SAP Ratings use the Government recognized Rating System of 1 – 100 to Part L Regulations that came into force on October 2010. To achieve a SAP Rating, detailed information will be required on all aspects of the design and materials to be used. Including the type of heating you intend using, the size and type of windows and doors plus information on the type of wall and roof construction to be included.
At the Design Stage, a SAP Rating can point to where any recommendations can be given on how to improve the specification and improve the SAP Rating and Efficiency of the Building. A Predicted Energy Assessment, PEA, will be produced, giving details of the Energy Efficiency and Environmental Impact of the new dwelling. Consequently a Building Regulation checklist will also be produced to ensure that all necessary criteria are being met.
Once your project is complete, we will check that no changes to specification have been made from the PEA and the Energy Performance Certificates (E.P.C.’s) will be produced. These are the Certificates required for Building Regulation compliance and give a rating between A and G according to energy efficiency and the environmental impact of the dwelling. Before E.P.C.’s can be issued they have to be registered by Landmark using a UPRN number, which is the (Unique Property Reference Number.) Once registered they can be retrieved from the Landmark Web Site and printed or forwarded on.
This information is also required by Building Control so that the dwelling can be signed off as being complete.
Passive House Design
Passive House is a German method of building principals based around achieving a high level of comfort through excellent building fabric efficiency.
As Certified Passive House Designers our aim is to provide you with an air tight, thermal bridge free construction that requires minimal heating, and, with the introduction of mechanical ventilation with heat recovery, provides you with a healthy home with even temperatures throughout.
The myth of not being able to open windows in a Passive House is not true, you just accept that the energy will be lost and not recovered to heat the new air entering the building. The performance of these buildings, a window open or not, is still far higher than provided by any other construction regulatory system in the UK.
The principals of Passive House can be adopted to suit any design of home and even renovation projects can aim to achieve the EnerPHit standards.
