What’s a positive house?<\/span><\/p>\n

What’s the price of a positive house?<\/span><\/p>\n

\n

Let me tell you we design and build your positive house.<\/p>\n

 <\/p>\n

May you don\u2019t know us yet, let\u2019s have a quick introduction: we’re ERA architects.
\nActually, I’m Esther Rovira, architect and passive house designer in Barcelona, Catalonia and Andorra for either passive houses, efficient houses and positive houses.
\nIn this post\u00a0\u2018What’s a positive house and price\u2019<\/em>, You’ll find our professional recommendation.
\nI hope it helps you. Let’s dig into it!<\/p>\n<\/div>\n

 <\/p>\n

Energy use<\/strong><\/p>\n

First, to secure an energy free house, you need to generate all the energy needed to deliver comfort inside.
\n<\/span>As you already may know, we use the German Passive house standards.
\n<\/span>The reason is that it\u2019s the most trustful simulator to forecast how your house will behave in the climate you’re located.
\n<\/span>However the Passive House Classic standards by itself doesn\u2019t secure an energy free house. Only a cozy low-consumption home (which may be good enough for you and that’s great!).
\n<\/span>If you want to add energy freedom, then you need to build your house by using the Passive House PLUS standards by using photovoltaic panels.
\n<\/span>That will assure your house will generate all the energy needed when it’s sunny. Yes that\u2019s right, only when it’s sunny.
\nMay you need to be 100% self sustainable home, mind to check our coming soon post ‘<\/em><\/span>Off-grid systems for your house’<\/span><\/em>.<\/span><\/p>\n

Water<\/strong><\/p>\n

Passive house plus standards help us simulate the house\u2019s behavior in terms of energy and comfort.
\n<\/span>However, this German standards doesn\u2019t say anything about water or biomaterials.
\n<\/span>Considering water will be a scarce resource in the future, we do apply our own systems to save and collect water.
\nMainly consists of: harvesting rainwater, recovering greywaters for gardening and treating wastewater for gardening.
\nMay you wanna know more in detail, mind to check our coming soon post ‘How to save water in your positive house’<\/em>.<\/span><\/p>\n

Bio materials<\/strong><\/p>\n

Finally, if you want to consider the carbon footprint of materials and the construction process, you\u2019ll need to use materials that are based on natural primary resources.
\nConsider only materials that have quality sustainable certificates such as ISCC plus (International Sustainability and Carbon Footprint) or RSB (Roundtable Sustainable Biomaterials).
