Despite the huge profitable savings potential, almost no investments in optimal energy efficiency of buildings are being made. Nor do building codes fully profit from Best Available Technology. This is what can be done to build a better, cleaner and richer future:
Authorities
Better energy codes It is technically and financially possible to erect buildings that are many times more energy efficient than the low demands for new buildings today. Improve energy demands by 30% every five years - then today’s Passive House technology will become standard within 15 years in the best countries.
Energy efficient modernisation All buildings undergoing renovation should be brought up to modern energy standards. Not just buildings larger than 1000 m2.
Information & incentives There is a lack of knowledge among building owners about the huge potential for energy savings in buildings – and the ways to bring improvements into practice. Information campaigns and incentives, such as tax and VAT relief and subsidies, are needed.
Remove owner-tenant dilemma Building owners must be given strong incentives to insulate their buildings. Today few do, because it’s the tenant who pays the energy bill.
Don’t subsidise energy waste Low energy costs can be vital for the poor. But wouldn’t it be more prudent to subsidise energy savings instead of subsidising energy use as many governments do today?
Building owner
Use best practice Use the best available low-energy technology. An efficient house will save you massive energy costs and improve your indoor climate too.
Energy audit – and implement Let a professional fi nd your leaks! Most houses have significant energy savings potential. Carry out the energy savings today, not tomorrow.
Modernise energy efficiently No modernisation without insulation! Adding extra insulation to a roof or façade that needs renovation anyway is very cost effective.
Building industry
Sell good quality! Offer energy efficient solutions with the lowest lifetime costs. Selling energy inefficient buildings that are slightly cheaper to buy, but much more expensive to heat or cool, is not good customer service.
User-friendly solutions Develop total packages including solutions for building owners with few or no technical skills.
