Todays challenges in buildings

In the EU today, we spend 90% of our time indoors, inbuildings that consume over 40% of the total energyconsumption. Up to 30% of the building stock does notcontribute to nor provide a healthy indoor climate.

Looking into a future perspective of how we constructand renovate buildings, it is necessary to considerclimate changes, resource supply and human health.

Id put my money on the sun and solar energy. What a source of power!I hope we dont have to wait until oil and coal run out before we tackle that .

Holistic thinkingTo reduce CO 2 emissions from buildings, it isnecessary to look at a buildings overall qualities,properties and functionality in terms of energyefficiency, healthy indoor climate and renewableenergy . Together, these three key areas constitutethe core of what VELUX refers to as SustainableLiving the ability to continue improving the

quality of our homes and maintaining high livingstandards while reducing or eliminating CO 2emissions

An Active House has a healthy and comfortable indoor climate and requiresoptimal use of daylight and natural ventilation. Sustainable and low-maintenancematerials are used with a minimal effect on the indoor air quality. The housemust be flexible so it can be adapted to changing needs. The daylight conditionsmust be optimized by strategic placement of windows. Intelligent operation willprovide the windows with sun screening on warm days just as dynamic elementsin the building envelope can reduce the heat requirement of the house duringwintertime. Natural ventilation where windows are opened automatically whenneeded will contribute to a good indoor climate . Environment Challenge Althoughthe challenges we face are global, the local environment differs greatly, and manypresent solutions are only viable within fixed parameters. We need an open-minded approach to flexible solutions that take into account local cultural andinfrastructural differences. Environment Solution An Active House is designedwith focus on adaption to the special character and the climatic conditions of thelocation, as well as the choice of energy system for the house must be optimized inrelation to the local energy supply and structure. An Active House stands inrelation to the formations and vegetation of landscape and surrounding buildings, just as the local building tradition and the use of local materials are considered asarchitectural design parameters. The specific site will be decisive for the design ofthe building; through an extensive use of sunlight and daylight potentials , byensuring views to the exterior and by the interplay with the local environment.

Sustainable living in the world of tomorrowSustainable buildings are a decisive factor for a more sustainable

world. Besides obvious environmental benefits , theyenhance quality of life for people, boostproductivity at work , improve learning abilities inschools and reduce health costs for society.

Model Home 2020

One experiment is better than a thousand expert views

Villum Kann Rasmussen

Live experiments: The VELUXGroup has just completed a seriesof six experimental buildings inEurope and demonstrated how it ispossible to meet the buildingsrequirements of 2020 with theproducts available today. Thesebuildings address the dualchallenge of climate change andliveability.

VELUX Model Home 2020

VELUX roof windows are part of an entire system thatprovides people with daylight, fresh air and outlook.The underlying principle of the VELUX range ofproducts is to transform homes into selfsufficientorganisms that let daylight, sun and natural air flowinside, harnessing and controlling them to create theindoor comfort and energy conditions necessary forbetter living.

The use of daylight has been optimised to ensure the health and well-being of theresidents as well as to minimise consumption of electric light during daytime. Thehouse is 190 m2 and comprises 1 storey. The window area amounts to 40 % ofthe floor area (as opposed to the usual 20-25 %), with the windows placed in allfour facades as well as the roof to ensure plenty of natural light, distributed deepinto all rooms.
