An eco-first for Scot­land

En­erPHit: ‘A so­phis­ti­cated and re­li­able way of build­ing in an eco­log­i­cal, sus­tain­able and eco-friendly method.’

Scottish Field - - ABODE -

Au­gust 2018 saw a first for Scot­land when a once draughty, tra­di­tional barn was cer­ti­fied as one of the coun­try’s most en­ergy-ef­fi­cient homes. Thomas Robin­son Ar­chi­tects had the very first En­erPHit cer­ti­fied build­ing in Scot­land signed off. En­erPHit is for ex­ist­ing prop­er­ties what the Pas­sivhaus stan­dard of en­ergy-ef­fi­cient build­ing is for new­builds. con­struc­tion, show­ing ev­ery stage. ‘This de­gree of rigour is not some­thing that the con­struc­tion in­dus­try in Scot­land is used to. It re­quires the con­trac­tor to fully em­brace it and every­one on site to un­der­stand what is at stake,’ said Tom.

En­erPHit is used for retro­fit or ren­o­vated houses, where the pres­ence of older ma­te­ri­als, a crum­bling barn wall, for ex­am­ple, means that dif­fer­ent meth­ods are used to cre­ate ex­treme en­ergy ef­fi­ciency. There are ap­prox­i­mately 1,000 cer­ti­fied Pas­sivhaus build­ings in the UK. Of these around 56 are En­erPHit projects, but this is Scot­land’s first. Thomas Robin­son and his team have cre­ated an ex­cep­tion­ally eco-friendly home from what was an old barn. En­erPHit ad­heres to the Pas­sivhaus aim to re­duce car­bon emis­sions, im­prove en­ergy ef­fi­ciency and ul­ti­mately achieve greater en­ergy se­cu­rity, while cre­at­ing an ex­cep­tion­ally pleas­ant en­vi­ron­ment. This is done via a va­ri­ety of meth­ods. Tom said: ‘Achiev­ing com­pli­ance for this build­ing was not straight for­ward and many of the ob­vi­ous mea­sures that could have been done such as mak­ing the south fac­ing open­ings larger were not avail­able to us. How­ever, we’ve done it and we and the client are ex­cep­tion­ally pleased with the re­sult. ‘We over­came chal­lenges in­clud­ing get­ting plan­ning con­sent for a large glazed open­ing to op­ti­mize a mag­nif­i­cent view where in the­ory no glaz­ing could be al­lowed. Achiev­ing the En­erPHit stan­dard in the Pas­sivhaus method in the com­puter en­ergy model in­volved care­ful balanc­ing of glazed ar­eas, high qual­ity com­po­nents and con­struc­tion de­tail­ing to elim­i­nate cold bridges.’ Mike Roe of Warm Low En­ergy Build­ing Prac­tice cer­ti­fied the project de­signed by ar­chi­tect Tom Robin­son, and built-in cen­tral Scot­land, is­su­ing a unique ID num­ber along with a plaque. To get a Pas­sivhaus build­ing cer­ti­fied re­quires that an in­de­pen­dent Pas­sivhaus Cer­ti­fier like Mike to check the Pas­sivhaus Plan­ning Pack­age soft­ware cal­cu­la­tions car­ried out by the de­signer.
