Forget CO2, global warming Gas takes over as main energy source for electricity generation Gas prices rising UK now importer of natural gas, likely to be the biggest by GDP by 2017 Supply and demand – electricity prices will rise Nuclear – time to construct and commission Increase energy from wind, tides, etc – technically difficult to manage peaks Invade Norway? CONSERVE WHAT WE’VE GOT
Regulations Paper regulations – red tape Feel good factor Financial
Planning 10% renewable – no proof of effective energy saving
Salix – apply, implement, payment (interim?), repay. £5000 min, any max

Transcript of "The investment case for reduction in building energy consumption"
Barry Shambrook Founder, Building Energy Reduction initiatives The investment case for reduction in building energy consumption
Incentive types Feel good factor/Corporate Social Responsibility Laws, enforceable regulations Red tape, regulations requiring paper Financial penalties / rewards
Incentives - Hole in the ground stage Planning requirements Part L building regulations Lifetime cost? BREEAM?
Incentives – Sale or lease stage Energy Performance Certificate Energy cost?
Incentives – Private sector “mature” buildings Plant inspection reports CRC Carbon Trading EN14001 ECA tax allowances Feed in tariffs Clause A.4.6 of ISO 14001 states: “ An organization should evaluate those of its operations that are associated with its identified significant environmental aspects and ensure that they are conducted in a way that will control or reduce the adverse impacts associated with them, in order to fulfill the requirements of its environmental policy and meet its objectives and targets”. Potential effect of higher energy prices + CRC Carbon trust loans

Traditional “input” procurement – specify, tender Advantages Disadvantages Proven and understood Time for implementation Standard contracts available No guarantee of energy savings Competitive Best quality? Use of loans and other incentives Best value?
Shared or surrendered energy savings Advantages Disadvantages Guaranteed energy savings Lack of control No investment cost Cost of finance Cannot be used with loans and other incentives
Suggested alternative risk sharing Deposit, 10%? Main payment
