ModelHome 2020 - Strategic focus on daylight, indoor

1 ModelHome Strategic focus on daylight, indoor climate and energy for sustainable living in buildings.

2 Today s challenges in buildings In the EU today, we spend 90% of our time indoors, in buildings that consume over 40% of the total energy consumption. Up to 30% of the building stock does not contribute to nor provide a healthy indoor climate. Looking into a future perspective of how we construct and renovate buildings, it is necessary to consider climate changes, resource supply and human health.

9 Our VISION for future buildings is based on two key principles LIVING FACTOR: Optimal daylight, fresh air and indoor comfort ENERGY DESIGN: A climate neutral dynamic building envelope

11 An Active House has a healthy and comfortable indoor climate and requires optimal use of daylight and natural ventilation. Sustainable and low-maintenance materials are used with a minimal effect on the indoor air quality. The house must be flexible so it can be adapted to changing needs. The daylight conditions must be optimized by strategic placement of windows. Intelligent operation will provide the windows with sun screening on warm days just as dynamic elements in the building envelope can reduce the heat requirement of the house during wintertime. Natural ventilation where windows are opened automatically when needed will contribute to a good indoor climate. Environment Challenge Although the challenges we face are global, the local environment differs greatly, and many present solutions are only viable within fixed parameters. We need an openminded approach to flexible solutions that take into account local cultural and infrastructural differences. Environment Solution An Active House is designed with focus on adaption to the special character and the climatic conditions of the location, as well as the choice of energy system for the house must be optimized in relation to the local energy supply and structure. An Active House stands in relation to the formations and vegetation of landscape and surrounding buildings, just as the local building tradition and the use of local materials are considered as architectural design parameters. The specific site will be decisive for the design of the building; through an extensive use of sunlight and daylight potentials, by ensuring views to the exterior and by the interplay with the local environment.

20 VELUX Model Home 2020 VELUX roof windows are part of an entire system that provides people with daylight, fresh air and outlook. The underlying principle of the VELUX range of products is to transform homes into selfsufficient organisms that let daylight, sun and natural air flow inside, harnessing and controlling them to create the indoor comfort and energy conditions necessary for better living.

24 Home for Life Home for Life is the result of an interdisciplinary project to synthesise the parameters of energy, comfort and visual appeal into a holistic entity, where the parameters are mutually complementary and maximise the quality of life in the home and the world around it.

27 The use of daylight has been optimised to ensure the health and well-being of the residents as well as to minimise consumption of electric light during daytime. The house is 190 m2 and comprises 1 ½ storey. The window area amounts to 40 % of the floor area (as opposed to the usual %), with the windows placed in all four facades as well as the roof to ensure plenty of natural light, distributed deep into all rooms.
