Consultancy services

We want to enable you to achieve the best you can in the context of your objectives and your resources. Good buildings are a comfortable temperature in winter and summer, are healthy to live in and don’t need much energy to achieve that, now or in the future.

In order to complement our existing products and our vision for the construction of low energy homes in this country, we are offering the following services to self-builders and their architects:

Low Energy Design Service

Our Low Energy Design Service aims to empower architects and self-builders during the early stages of design by providing them with informed and quantified decisions regarding the building fabric specification. This includes crucial factors that feed into a building’s performance, such as U-values, windows, airtightness, and ventilation. Our approach involves generating an initial whole building energy model using the Passivhaus Planning Package (PHPP).

Heating & Ventilation Specification

With low energy and Passivhaus homes having unique heating requirements, this service concentrates on the appropriate specification of air source heat pumps and room heat emitters for such homes. Leveraging architect’s drawings and design data, including fabric details, airtightness levels, window schedules, and ventilation data, our service produces precise room-by-room heat loss calculations that are in accordance with the MCS standards expected of heat pump installers. If an MVHR design has not yet been completed, we can include a basic MVHR specification in order to determine ventilation heat losses accurately.

Design Review

A practical review of your building plans with Director Bill Butcher, to help guide your project team to deliver energy efficient, up to Passivhaus standard, building projects.

Our Design Review focuses on building professionals and their clients working on domestic residential projects helping them to meet Passivhaus, EnerPHit and AECB  low energy building standards.
