What do you know about energy saving design?

Recently I was researching about energy saving desing projects and it seems like those projects become more and more popular in Europe. One of the reasons to do energy saving renovation and design is to make building more self-efficient, and in some cases even make building to produce energy insetad of using it. In Copenhagen energy saving renovation is on the top of the list of Climate Plan 2025, the strategic document for city development. The main goal of the Climate Plan is to reach zero level of CO2 emissions by to 2025, so Copenhagen can be the first CO2 neutral capital in the world. Construction industry and building maintenance have a big impact on the environment and results in large amount of CO2 emissions. That is why energy renovation and design play a crusial role in sustainable development. To clearify a bit more about different factors in energy saving design I will talk about 3 realised projects that show different approaches to how to build and renovate for better environment.
Project 1 Upcycled Family House, built in 2013
by Lendager Architectslocation: Nyborg, Denmark

The main focus in house design is to use recycled and upcycled building materials, ranging from old shipping containers, recycled wood and gypsum sheets, paper from recovered newpapers, aluminium facade plates made from cans, used car tires etc. By using recycled materials we can reduce the potential environmental impact up til 25 percent compare to a house built with commonly used materials. This approach shows quite clear that recycled materials can be durable and environmental friendly, and with a good design also reduce the construction costs. However not all of the solutions used in this house design are possible to use somewhere else due to availability of materials.

Project 2 Lichtaktiv Haus, rebuild as a Model Home 2020
by Ostermann Architecten
Location: Hamburg, Germany

Energy saving approach converted this typical one-family house into a CO2 neutral house. The house uses solar energy with PV and solar thermal collectors, natural ventilation and passiv solar warming with help of a large amount of glass, that also gives plenty of daylight. Energy comes also from heat-pumps, and in total gives 16 kWh/m2/year, that fullfills the standards of livability for 2020. The house was built as an experimental model and its development and construction was supported by range of companies, like Velux, Sonnekraft, HL Teknik etc. Lichtaktiv Haus shows how smart design together with sources of renewable energy enable a holistic approach in energy saving renovation.

Project 3  “Green Towers” Deutsche Bank Headquarters, renovated 2011
by Mario Bellini ArchitectsLocation: Frankfurt am Main, Germany

A pair of reflective glass towers is the most recognizable symbol of the bank in Germany. The building was build in the 80’s and undergone complete renovation in 2011. Energy modernisation included change of facade materials, heating, water and lighting systems. The facades have been reglazed with opening windows that turn it into a climate facade. The windows opening parallel to the façade are equipped with motorized scissor hinges – making it possible to have natural ventilation. That is how the towers perform now: 67 % less energy used for heating and cooling, 55% less electricity consumption, 74% saving in annual water use, 89% less CO2 emissions (that by the way corresponds to the amount of CO2 emissions of 6 000 cars each driving 12 000km) and 98% of used materials are recyclable.
As you can see there are different approaches in energy saving design, but there are two main goals behind this: to reduce carbon footprint (that is good for the environmental, ressource consumption and people health in general) and to pay less for heating, electricity, warming, cooling etc. (that not only saves our money, but also gives us a good reason to change our behavior).

Peter Stutchbury

Yesterday I went to the Danish Architecture Center for a lecture by australian architect Peter Stutchbury.
I was so much impressed by his works! In my opinion it is the best combination of sustainable and contemporary architecture I have ever seen! With a high level of quality in every single detail. Amazing work with water surfaces on top and around the buildings. Very inspiring work with climate adaptation of every house he made.
You can see his houses here.
