Glasgow Ice Box Challenge: Student Design Competition Launch

 

 

 

In response to the priority action points set by the UN Climate Change Conference, COP26, hosted by the UK in the City of Glasgow, Scotland this coming November, the Passivhaus Trust UK and the International Passive House Association (iPHA) in partnership with Edinburgh Napier University (ENU) is launching an Ice Box Challenge and accompanying student competition to demonstrate the benefits of an efficiency first design approach.

 

To create awareness and inspire young designers and architects in Scotland, this student competition, with the support of key participants such as the Glasgow City Council, Construction Scotland Innovation Centre (CSIC), Glasgow Institute of Architects and John Gilbert Architects, invites students to submit design entries for the creation of two small ice box structures. The Glasgow Ice Box Challenge seeks entries where one-box design will be built to Scottish Building Standards and another to the Passivhaus standard criteria. In order to evaluate and demonstrate performance during the public display, each box will hold an equal amount of ice allowing it to melt. The differential in melted ice will demonstrate to the public the thermal benefits of a high-performance building envelope.

 

The initial stage of the student competition asks groups of students and recent graduates from all built environment and Architecture Schools and Universities in Scotland to submit an entry for the design of the ice boxes. The top three groups will be invited to take part in an online presentation to a jury. All finalists will be given free access to the Passive House Fundamentals E-learning content, the latest Passivhaus Planning Package (PHPP) energy balance tool and a year's membership to the Passive House Trust UK and International Passive House Association. The winning design will be built and placed in St Enoch Square, Glasgow for the Ice Box Challenge in July 2021. The group will also be awarded £1,000 by the Glasgow Institute of Architects (GIA), after the fabrication and public display stages. There is also a cash prize of £300 for second place and £200 for third place available after the presentation stage.

 

The design brief can be downloaded at the link below. Please submit questions or queries to Louise Rodgers at l.rogers@napier.ac.uk.

 

Final submissions are to be made electronically, in pdf format to: l.rogers@napier.ac.uk by Monday 23rd of May 2021.

Announcing the "Efficiency: The First Renewable Energy" #EfficiencyFirst Campaign

 

 

The past decade has seen increased awareness of the need for renewable energy and reducing embodied energy in the building sector. Together with our affiliates, our global #EfficiencyFirst campaign aims to raise awareness of the foundational aspect of sustainable buildings that is too often overlooked: Energy efficiency.

 

Currently, 35% of global energy consumption stems from the building sector alone and the operational stage is the largest contributor to carbon emissions. The majority of this stems from heating and cooling demand. Passive House buildings provide a transparent, quality-assured approach to meeting our climate goals, while also creating a comfortable, healthy and sustainable built environment.

 

Over the course of 2021, the iPHA network will be running a series of activities and events with the aim of promoting the significance of an efficiency first approach to building design; wherein buildings are planned, constructed and retrofitted to have an extremely low heating and cooling demand.

 

Find out more about the #EfficiencyFirst campaign here.

The key to a healthy climate

 


The 25th International Passive House Conference will take place from September 10-11th in Wuppertal, Germany, under the patronage of Andreas Pinkwart, North Rhine Westphalia's State Minister for Economic Affairs. Only buildings with a low energy demand for heating and cooling will put us on the path to efficient climate protection. By reducing the energy demand, we can ensure that our building stock’s energy needs can be fully met by renewable energy sources, long term and at large scale. Encompassing this idea is this year’s International Passive House Conference and complementary exhibition, which bare the motto "Passive House - The key to sustainable buildings!”

Ventilation systems strongly recommended

 


With the start of the cold season, attention is increasingly shifting to schools and the question of how the risk of infection with the Sars-CoV-2 virus in classrooms may be reduced. The German Environment Agency recommends frequent air replacement; in schools that do not have ventilation systems, this air exchange should be achieved by opening the windows. The German Environment Agency expressly advises against mobile air purification units as a substitute for ventilation with fresh air. These mobile appliances should only be used in addition to active ventilation. The Passive House Institute endorses this recommendation and draws attention to the advantages of a ventilation system with heat recovery.

Build better than required by code!

 


This year the final applause was shared in the chat window: the participants expressed their appreciation for the 24th International Passive House Conference, which was held as an online event for the first time on account of the COVID-19 pandemic. Over the past three weeks, more than 800 participants around the world tuned in and listened to the lectures on energy efficient construction and retrofit solutions from their own screens.  The virtual Passive House Café was open 24/7 for international networking. The conference conveyed two important messages, amongst other topics: deep energy retrofits need to be carried out on a broader scale, and construction practices must exceed the mostly inadequate code requirements for energy efficiency. The 25th International Passive House Conference will be held in autumn 2021 in the German city of Wuppertal.

Pointing the way – then and now

 


Construction of the first Passive House in the world started 30 years ago in Darmstadt, Germany. The building physicist Wolfgang Feist had developed the Passive House standard prior to this. In the autumn of 1990, he started putting theory into practice with the construction of the private terraced housing complex. Since then, countless buildings have been built to the climate-friendly Passive House standard around the globe. Current projects and research findings will be presented at the 24th International Passive House Conference from 20 September until 8 October 2020. The Passive House Institute presents ten reasons for attending the online conference.

Hospital a step closer to certification

 


The world’s first Passive House hospital, currently being built in Frankfurt, Germany, is a step closer to certification: an airtightness test for the building, which spans 78,000 square metres of gross floor area, was extremely successful. The Passive House Institute in Darmstadt has been consulting on this pilot project right from the start, including the initial planning phase. It has now been tasked with the certification of the project. A baseline study on the implementation of the Passive House standard in hospitals was carried out in advance by the Passive House Institute on behalf of the German Federal State of Hesse.

Passive House social housing project winner of this year's Stirling Prize!

 

  

The Royal Institue of British Architects has awarded the 2019 RIBA Stirling Prize for UK's best new building to a Passive House development. Goldsmith Street, developed by Mikhail Riches with Cathy Hawley, comprises 100 highly energy-efficient Passive House homes in the city of Norwich. The low energy consumption not only saves the residents a lot of money but also makes the houses highly sustainable and climate-friendly. Stylistically, the design pays homage to Norwich's history while embracing the future. It combines the creamy clay bricks of Victorian terrace houses with modern Passive House building techniques. Having RIBA award this project with their esteemed prize is a testament to the tradition-steeped organisation's transition into one of the most progressive and sustainably-minded architectural associations.

A new addition: energy efficiency!


The two buildings are used completely differently, but they have one important thing in common: both buildings have achieved the EnerPHit standard after an energy retrofit. The Passive House Institute recently presented the certificate for the EnerPHit retrofit of a supermarket in the Austrian town of Prutz. About 7800 kilometres away, a clothing factory in Sri Lanka also received a certificate for a successful energy efficient modernisation. This pilot project in the tropical climate will be presented in October at the 23rd International Passive House Conference in China.
