Low Energy Design have the knowledge and experience to guide you to positively invest in well designed buildings to best practice standards through architectural and passive house consultancy services.

Buildings to delight and deliver

Passive House Design

As your passive house designer (including EnerPHit projects for refurbishment), I would ideally like to be involved early in the design process. This can be a service on your project with Low Energy Design or I can work with your personal architect or engineer if you wish on passive house design issues only. Passive House Planning Package (PHPP) is the software developed by the Passive House Institute in Germany for use worldwide in comprehensively analyzing the energy performance of your project using building physics principles. Minute detail of every pane of glass is entered along with floors, walls and roofs, ventilation, solar gain, electricity, airtightness, water heating and thermal bridging. PHPP when complete can be used to iteratively analyse the design performance of the various elements to optimize the design. Detailing is key to almost zero thermal bridges desired in Passive House for each fabric junction along with window installation. This is an area that is also key to airtightness performance. Should you choose to obtain Certification for your project from the Passive House Institute, the PHPP will predict compliance and we can work with approved certifiers to achieve your goal.  

Architectural Design

Walking You Through A Design Phase, That Takes Account of Your Identity One of the most exciting parts of the journey is at the design phase. The possibilities are endless; and I encourage my clients bring their ideas, clippings, photos, checklists and other items that set the mood, tone and style of what they like (and what they definitely don’t want), to really understand what it is you want to achieve. Very soon ideas from both client and architect begin to flow in a synergy and joy that is directed towards your project. The Design & Build Process As an architect I deal with many clients, who are unsure of the entire process, from conceptualisation to realisation. Building a custom designed home can be intimidating if it’s a process you’re not familiar with. I’ve heard horror stories of homeowners barely surviving, having wasted thousands of euros with contractors who took advantage when they have the upper hand, or being tied up in court, slowly losing their sanity when they realised they were out of their depth. It doesn’t have to be like this. Planning your home should be a methodical, logical process and proceed in a step by step manner to get the right people to do the job. In fact it should be a delightful and exciting process. It’s about having a game plan and an expert on your side to guide you through the most complicated stuff – how to select a contractor, determine the right price structure and secure it with a contract, down to the last detail. As one of the most expensive endeavours in a lifetime, it’s important that you have a written contract to protect yourself in the event that something goes wrong. I can help you with all of this.

Thermal Bridge Modelling

Increased levels of insulation have put more emphasis on the building fabric junctions, where there is a change in direction in plan or section, a change in material or thickness and where different components join to make up what is called the building envelope that protects and keeps you comfortable in your home regardless of the external environment. These junctions can be analysed using computer thermal modeling techniques for both Building Regulation compliance and Passive House. Thermal Bridge losses can account for 25% of the fabric heat wasted in a highly insulated dwelling so getting them right can have huge benefits. Low Energy Design have third level Diploma level course training in the first progamme of it’s kind worldwide and offer thermal modeling to improve your BER, compliance with Part L of the Building Regulations or demonstrating accurate psi values for Passive House Design. James Walsh has been accepted for the NSAI Approved Thermal Modellers Scheme competent to thermally model junction details and calculate their linear thermal transmittance as allowed for in Part L of the Building Regulations and as part of Y factor calculations entered into DEAP for Building Energy Ratings.

About Low Energy Design

It is my mission, in partnership with my clients, to develop inspirational, relaxing and enjoyable living spaces through architectural design that combines clean elegant lines with low-cost energy solutions and to work with my clients vision for their home, whether it’s a new-build, conversion or extension. My philosophy is that your home is a reflection of you, your identity and your values and I work hard to get beneath the surface, to truly understand what it is you want to achieve. What’s important to you – lots of family space, entertaining, quiet spaces, or being green? It’s important to decide these things before you begin.

Thermal Bridge Assessment

We prepared this guide after seeing so many people struggle with understanding thermal bridge assessment. This process can seem like a complex and frightening roadblock for those who haven’t been through it before. Best of all you can get a 20% discount on my thermal modeling services when you download a copy of Thermal Bridge Assessment – Frequently Asked Questions.

Why do we provide free educational tools and resources to people like you?

Simple. I am an architect in the low energy design and passive house field who has has seen many details that could be better thought out –
and I would prefer to help people avoid the costly stressful mistakes rather than come in as the ambulance.
